Apertures Float Like a Butterfly

We get letters ♫ … I got an email recently regarding apertures from a compound archer. Some interesting points were raised. Here it is:

Steve,
I’m working on a steadier hold. I switched to a dot from my aperture because the new (kinda) 80 cm target for compound @ 50m didn’t work with the aperture I’d been using for the 122cm target. That aperture also worked perfect in my garage at 28 feet as well as 18 m indoors. The dot seemed to be the same size at all distances. I was doing holding drills this week and tried both the dot and empty aperture, then noticed something interesting. When using the dot, it wanders out of the gold and you don’t want to take a shot when it does that but when using the aperture you always have some yellow in the circle made by the aperture even when the dot would be out. It’s an illusion, somewhat, you’re always in the yellow while you’re “out” with the dot even though it’s really the same position you’re holding on.

Here’s my response.

* * *

For compound people, there are a multitude of rings in different diameters and thickness … and colors to try. You can even combine rings and dots and use one or the other under different situations.

You were perceiving what is called relative steadiness. A bigger dot seems to move less than a smaller one (possibly because the extent of the motion is a fraction of the diameter of the larger dot, rather than a multiple of the diameter of the smaller one). Same is true for larger rings/apertures v. smaller rings/apertures. If you are using a central dot in your aperture, you want to have the dot be small enough it does completely cover the gold, nor does it leave the gold often. This is why I prefer a larger ring decal on my scope lens apertures. The gold floats inside of the ring and provides the information my brain needs to see that it is “centered” in that ring.

Imagine a dot so big it covers the gold. (Some have used old sight pins with beads glued on the tip to create such a thing for indoors compound archery.) In this situation one feels the urge to move it off to see if the gold is actually behind the dot. If you are in a situation like that, due to the distance to the target, it is better to “see” the dot as being inside, say, the blue ring, and looking to have it centered in that ring because the gold is not helping. On a target like the NFAA Hunter targets, you are SOL as there is only the small central dot on the face and no outer rings to help as with the parti-colored target faces.

Small dots make you feel more jittery, larger ones less so, but larger rings/apertures include the ability to see what is behind the aperture while keeping the sense of stillness.

We are never perfectly still. The fact that out hearts beat continuously, and each beat changes the location of our center of mass slightly, which means we can never be perfectly still. So apertures, scope lenses, dots will always be seen to be moving. Small objects moving a distance equal to their own size appear to be moving a lot. A large object moving the same distance appears to be moving very little. The empty ring aperture (recurve) and the ring decal applied to scope lenses (compound) provide the best of both.

Again, these are my opinions, my analyses. There ain’t no gospel here. If you are someone which an elevated innate sense of calmness, you made need no extra help like this. I am not one of those people and was born jittery, so I needed all of the help I could find. Steve

The Selling of BS

I was reading a blurb for yet another golf video lesson and I ran across the words “Speaking of draws, not many amateurs can hit one … especially with the driver…. What’s the big deal about a draw, anyway? Well, did you know a draw travels 31 yards farther than a fade hit with the same swing speed? It’s a fact, proven by a Golf Labs robot.

Ah, the Holy Grail of amateur golf, hitting a draw. A draw is a shot that curves slightly from right to left (for a right-handed golfer). The factoid they supplied is indeed probably right (assuming the club was a driver, the longest distance club), but it is also irrelevant. A draw will go father than a shot curving the opposite way, a fade, using the same club. The reason is that the technique used to hit the draw involves turning the club in your hands so that the club’s face is more upright. A more upright club face means the ball will travel more forward and less upward, so farther. To hit a fade, you must do the exact opposite, tilt the club face slightly back away from vertical, which means more up and less out, resulting in a shorter shot.

What they don’t tell you is that if a fade is the result of your natural swing, you can compensate by using clubs with the faces a half degree or so more vertical. Voila. Now you get the same distance you would have gotten from those other clubs, hitting a draw.

Hello? Jack Nicklaus, arguably the most successful professional golfer of all time and one of the longest hitters of his generation, hit a fade. A draw is not necessary to hit it long. Sheesh.

But then, they had clubs to sell, clubs that make it easier to hit a draw.

This is the case in any sport in which there is gear to sell, like, say, archery. For a long time, bow manufacturers have been finding ways to make arrows fly faster and bragging about the arrow speeds their bows provide. And, the benefit(s)? Well, in most cases, the extra speed means that the angle the arrow makes with the ground is a fraction of a degree flatter. And we all know how that affects an archer’s accuracy or success at hunting. It … it … means … uh, hmmm, well … it means…. Yeah, diddly squat.

Addendum Professional golfers, some of them anyway, use this draw-fade difference to help them control their shot’s distances. Not only does being able to hit both kinds of shots with the same club allow them to “shape” shots to fit golf holes that curve to the left or right, but they can also use those different distances to make their clubs more versatile. If their driver goes 300 yards with a draw but they need the shot to go 285-290 yards, they can hit a fade with the same club and voila. (It is hard to hit draws and fades with higher lofted clubs, wedges, etc. so this is limited to the “longer clubs.” Although a common technique in hitting the “short irons” is to turn the club in one’s hands to change the angle of the club face to match it to the distance needed, which is the same idea. So this aspect of “a fade” going less far than “a draw” is not a bug, it is a feature. But when it comes to selling, any old factoid can prove useful.

Barebow, Barebow, Barebow

I just got an email from a viewer who had a boatload of questions about Barebow. (Hooray!) I love it when you send in your questions as it gives me ideas about what I should write about, so if you have them, please feel free to email them to me (ruis.steve@gmail.com).

Here’s Dieter’s questions:
So, the questions are:
• Does one have to close one eye when aiming off the point?
• My kind of split vision string- and face walking does work. However, did you come across someone who managed to combine the more “instinctive” split vision technique with aiming off the point brought right below the target without having to drastically alter button spring tension?
• Of course, I could decide for either technique. The benefit of split vision from 5 – 25 meters is, I do not need to crawl down the string and thus do not imbalance the bow. The other thing is losing accuracy on longer distances. I might also improve the closer distances aiming off the point.
• Maybe, my little problem is confusing. However, I’d be glad if you could share your experienced thoughts with me.
Best wishes, Dieter

* * *

And here are my attempts at answers! (Note I assume Dieter is referring to Barebow Recurve.)

  • Does one have to close one eye when aiming off the point?
    My opinion is that this is only necessary if there is a problem with keeping the off eye open. I, for example, shoot right-handed but am left-eye dominant. If I don’t half shut my off eye, I can end up with some bad misses. There are problems with shutting the eye completely (as with an “eye patch”) as this lowers the total amount of light coming into the eyes and therefore affects iris responses, etc. Eyelids allow some light it and people with glasses often resort to putting a strip of transparent tape over the off eye lens. This allows light in to an open eye but no clear image, so if the off eye “takes over” it will be easily noticed.
    This is the same whether you are aiming off the point and or using a sight.
  • … did you come across someone who managed to combine the more “instinctive” split vision technique with aiming off the point brought right below the target without having to drastically alter button spring tension? This is a very complex question. The “split vision” technique, as recommended by the likes of Howard Hill, is not really split vision as much as it is split attention. I am not a fan because while you are aiming that is the only time you are splitting your attention on what you are doing during an archery shot: you are attending to aiming and attending to completing the shot via swinging the draw elbow around, squeezing back muscles, or whatever. Splitting your aiming attention in two results in a three-way split in attention, something I am not a fan of. But then, I am a fan of whatever works, as long as we know what actually works, so if the “split vision technique really works for you, then go for it. (That you asked the question indicates it is not working well enough or under the circumstances you encounter.)
    Two topics are being addressed here in addition. One can aim off of the point several ways. The two primary ways are gap shooting (basically aiming off, with “gaps” being the amount of high or low aiming) and stringwalking. Since the grip of bow and sting do not vary when gap shooting, no adjustment of plunger tension is needed. However, when string walking, whenever the “crawl” (the distance down from the arrow the string is “gripped”) is changed, you are essentially de-tuning the bow. The draw length changes, the draw weight changes, the tiller changes, everything. These changes are small and successful Barebow Recurve stringwalkers focus heavily in finding a bow tune that represents a “happy medium compromise.” Usually, since the shorter distances are shorter and therefore easier (in field archery) they allow for a poorer tune there and set up for a better tune for the longer, and therefore harder, shots.

    Taking a crawl on a longbow.

    So, elite Barebow Recurve Archers who stringwalk have this unavoidable dilemma. Some use plunger adjustments at the extremes of their distances to help with this problem, so you are not wrong in doing that. The ultimate tune, though, for such an archer is one that doesn’t involve such adjustments, so these archers work on their arrows obsessively and their plungers to find a “no fiddling tune” if they can. If such plunger adjustments are required, you need to adjust your shot sequence to make sure that you add or subtract known numbers of turns on your plunger button and then take them off when no longer needed. Forgetting to do these things are mental mistakes that always lower scores, so eliminating the need to make such adjustments reduces the number of possible mental mistakes, which is a good thing … if you can pull it off.
    Sorry, for being so long winded on this one, but that’s the best I can do. Possibly more expert Barebow archers will chime in in the Comments.

  • Of course, I could decide for either technique. Yes, you can. There are some who insist that this technique is better than that technique. I have never seen a case in which this has been proven, unless you put up some form of standard technique against, say, standing with your back to the target. The entire reason we all shoot much the same way, with only minor differences, is that in the 60,000–70,000 year history of archery, the bow has taught us what works and what doesn’t. So, most of what you can find being currently recommended by archers and coaches works! That’s the good news. The bad news is “so does all of the other stuff.”And the only way you can tell “what works for you” is to try things out. Unfortunately, the things being tested against one another are so similar (they may feel really different, but they are not … to the point that onlookers may not notice that you have changed anything) that it takes many weeks of trying out the new thing to see if there is a real effect or not. There are very many things to try, and not enough time and effort to try them all, so you just have to pick.

    What I do know is this: the key factors are whether an archer has committed to a new/different technique and practiced it in and … in my not so humble opinion … simpler is better. If you try an aiming technique and it only works for shorter distances and you need another for longer distances, I would keep looking. What you want is a technique that is the same for all shots you take on a certain course, e.g. WA Field Unmarked shots are never longer than 50 m, WA target shots used to be longer (30-90 m for men) but now seem to have been shrunk down to just 50 m for target events. I would have separate bows set up for the two kinds of events. If I couldn’t afford two bows, I would have two bowstrings and two sets of bow settings for the two events. I might also, depending on budget, have two sets of arrows tuned for two different events. (Consider archer’s arrow choices for indoor and outdoor events as a model.) The gold standard for FITA Field Barebow archers shooting unmarked targets is a single anchor with a single set of crawls from 50 m on down to the shortest shot (don’t remember this … 5 m?).

    I prefer having a single technique for a single event. When I teach stringwalking, we start at close up, determining the archers point on target distance (POT) and then determining their set of crawls for distances inside that distance. Then we change from a high anchor to a low anchor and determine the new POT for that anchor (much farther out) and a set of crawls there, too. (Often the crawls are amazingly consistent, e.g. the same crawl for five meters closer than POT distance for both anchors, which makes memory mistakes less likely). What we hope is these two ranges overlap, covering all of the distances being shot. If they do not, instead of adding a third technique, we look to changing things like draw weight or slight changes in anchor hand position to get what is desired.

My rule of simplicity would rule out string walking as a tool for tackling a FITA Round, for example. There were/are only four distances. It is far easier to determine four points of aim for the four distances (if they are on target) than employ stringwalking with its detuning characteristics. But for a Field Round in which targets are placed at many different distances, having a different point of aim for each target is too cumbersome, there stringwalking shines. So, there are legitimate reasons for having a “bag of tricks” to employ for aiming at various kinds of events as “one size never fits all!”

I hope this helps more than it hinders!

NFAA Trims Back Styles

When I got up this morn I found an email from the NFAA (US) in my Inbox indicating that they have trimmed back the list of recognized styles. And as one might guess, the numbers of “fingers” (versus “release”) styles are the ones being trimmed.

Here’s the list from that email, in case you are interested but didn’t get the memo:

So, since I first jointed the NFAA (1990), the list of styles no longer available is:
Bowhunter (Adult and Youth)
Bowhunter Freestyle Limited (Adult and Youth)
Longbow (Adult Only)
Freestyle Limited (Youth Only)

I do not know the data or politics behind these changes, so please do not ask.

A number of styles have been added since that time (Freestyle Limited Recurve is basically Olympic Recurve, plus some of the Pro styles).

Quiver Protocols

There is much information in archery that is needed to be learned and mastered that just doesn’t show up much in print or video anywhere. I was reminded of one such bit as I was chaperoning some new field archers around a field course this last weekend. I have written about this topic in one of my books, but I guess it is worth restating here.

The penalty for shooting an incorrect number of arrows is steep. Obviously, if you do not shoot all that you are allowed, you left scores in your quiver. If you shoot extra arrows, the rules penalize you and, to be effective, the rules must penalize you more than you could gain from the extra arrow(s). A common penalty for shooting an extra arrow is to lose the score of the highest scoring arrow on the target, or even the highest scoring arrow score plus one more point.

To prevent such mistakes, we create habits and one such is using a quiver protocol. I will describe my quiver protocol as an example, and you can take it from there. I use four-tube side quiver. A hip quiver slid around your back is great for indoors, but doesn’t allow you to see your quiver. Ditto for a back quiver. Seeing how many arrows are left in your quiver is at the core of all of my quiver protocols.

This is a four tube quiver. I made my first quiver as a back quiver, then modified it to be a side quiver, and then modified it to add tubes. (The tubes we got from golf stores.)

Of the four tubes in my quiver, I shoot from the top tube downward, meaning I empty the top tube before taking arrows from the next tube down. I do this this way because when I drop my hand down onto my arrows, the first arrow I touch is in the topmost tube which still has arrows in it. In this fashion I can pull an arrow out without looking at my quiver.

I reserve the bottom tune for “spares and defective arrows.” The spares are put in normally, but if I put an arrow in my penalty box because it is broken or bent, etc., I place it in fletches down, rather than fletches up. This distinguished the spares from arrows that must not be shot.

The top tubes are then used to distribute the arrows that will be shot. The basis for the distribution is our ability to count things without, well, counting them. For example, if someone rolls a die, do you have to count the pips on it to determine their number? The answer is no, because each face of a die has a distinctive pattern that is recognizable. If there are pips in all four corners and one in the center, it is a five. If there are pips in all four corners but none in the center, it is a four. Once you learn the trick, you never again count “1, 2, 3, 4 … that’s a four.” We learn this at, what, four or five years of age?

In any case, we want to set up our quiver to take advantage of this ability. For a shoot with six-arrow ends, we could just stuff all six arrows in the top tube and shoot them one at a time. But if there were only five arrows in that tube, instead of six somehow, would you notice? Possibly not. My quiver protocol has me putting two arrows in each of the top three tubes (3 x 2 = 6). When I glance at my quiver, if the tubes are “full,” meaning have two shafts in them, I am good to go. And a tube with two is easily distinguished from a tube with one or three just by looking, no “Uh, 1, 2, 3 … damn!” When I have shot my first arrow (from the top tube), if I look down there is one left in the top tube with two each in the next tubes. After the second arrow the top tube is empty. After the third arrow, there is an empty top tube and just one arrow in the second tube down. After the fourth, the top two tubes are empty, and … after the sixth, the top three tubes are empty. I never, ever, ever ever take an arrow out of the fourth tube and shoot it. Arrows taken out of the “spares” are only placed in the quiver in place of an arrow that was rejected, then they are shot from there.

If I am shooting in a three-arrow per end round, I start with two in the top tube, then one in the next, then an empty tube. If a five-arrow end round, I go “2, 2, 1, spares.” All of these patterns are as alike as I can make them. I always start with two arrows in the top tube, for example. This makes this ordinary and not something special just for this round, which requires additional thinking, something we try to avoid.

Using one’s quiver protocol over and over makes it automatic. I have not made the mistake of not shooting the correct number of arrows since I adopted the practice.

To make this work, you have to load your quiver carefully. This you do most often at the target aftre pulling your arrows while you might be engaged in chit chat with your target mates. You must clear the mental space to load your quiver correctly after each end. I use a mental trick of not allowing myself to move my feet until the arrows are quivered correctly. This is just an extension of not moving your feet until all your arrows are safely quiver, which is what we teach beginners for safety. (You can’t trip unless you are walking, unless you possess unusual “gifts.”)

Of course, there are all kinds of additional things of this ilk to learn. If an arrow is pulled from service do you know which one it is if it accidentally gets put in the wrong tube? (I number mine for this purpose.) Do you …

As a coach, these are things to teach your serious students. The advantage to them is if they offload some of these things into the realm of habit, there is less to distract the thought processes during the competition and fewer stupid mistakes to upset them.

Archers Need More Help with Stabilizers?

We have addressed the topic of stabilizers, primarily how they work, and how to get started using one. It seems that it is time to expand on that beginning. Here I am going to focus in on how you, as a coach, can help archers wend their way through a forest of stabilizers.

More Stabilizers, More, Please
It seems to me that many novice archers, young and old, rush to make their equipment look like the “good archers’” stuff. This is especially true of young archers whose moms and dads are archers. The problem with doing this is that such additional accessories may not help and might just hurt their progress in archery. Each new accessory changes how their bow feels and needs to be adjusted and tested. If your student does not shoot quite well yet, they may not be able to notice that there is no improvement in their archery from the addition of the XYZ Gizmo. And if they are adding mass to an already “too heavy” bow, they will be hurting their progress.

These accessories only make small differences in their results and if they really want positive attention for their skill as an archer, practicing and refining their form will probably pay off more than fiddling with their equipment.

That being said, you will probably not make many friends if you pooh-pooh each student-archer’s desire to add something to their kit. So let’s look at how you can help.

Getting Fitted
One of the areas archers need the most help is with their archery purchases. The archery marketplace is bewildering to even many seasoned archers, so it is especially so for novices and beginner-to-intermediate archers. If you prove valuable helping with these purchases, your opinion on subsequent ones will become more and more impactful. Besides, trying to help an archer is always one of the better things we do.

Fitting Long Rods Short stabilizers are limited in length by rule, but long rods are not, so let’s look at long rod fitting. An easy way to measure a student up for a long rod is to have them hold their bow at their side, string up. Have them allow it to hang as far as it will, but their hand should be in the bow as it is when shooting. Then measure from the stabilizer boss to the floor/ground. Add an inch to this length—this is a good first estimate as to what length of long rod to start on. If your archer is still growing, add another inch. If the long rod you are shopping for doesn’t come in that length, err on the long side, but not 5˝-6˝ long as that will be unwieldy.

As to how much the rod weighs: lighter is better (stiffer is better, too). The rule of thumb is a lighter weight farther out has a greater stabilizing effect than more weight closer in. There are now some carbon fiber long rods that are not too expensive that are lightweight and quite stiff, too. If on a tight budget, an archer can look for a used rod or a less expensive aluminum one. Some very gaudy scores were shot using aluminum stabilizers. Don’t fall for the “carbon is like bacon: it makes everything better” rule.

With regard to long rod “end weights” we recommend they start with none, maybe just a plastic cap to protect the threads on the end of the rod. If the rod comes with end weights, they can be just taken off (and put in a Baggie labeled and dated!) and added later when your archer is feeling experimental or just stronger.

Fitting Side Rods Side bars and V-bars themselves come in a number of variations. V-bar blocks (the block the side rods screw into) can be “fixed” or “adjustable” as to the angle. For compound archers, “one side only blocks” are available, but you can just use an ordinary dual rod block also, even though only one rod is the norm. The V-bars themselves come in various lengths, sort of small, medium, and large. If your student is fairly short in height, they should get the short side rods. If they are fairly tall in height, recommend they get the long side rods. If in the middle, have them get the mediums. If an adjustable block is used, the angle the rod makes with the bow tunes the effective length of the rod.

To fit them, they need to be attached to the bow and your archer needs to shoot some to adjust to the new feel. After this “break in” period, you need to ask them how the bow feels. If they pay attention, they will notice whether the bow tends to react left, right, up, or down. If they do not notice, have them shoot some arrows blind bale, specifically asking them to pay attention to how stable the bow feels at full draw and which way the bow tends to move when the shot is loosed.

Angling the side bar or bars downward moves the weight distribution from back to front (and the reverse does the opposite). So, if they feel like the bow is “rolling back” in their hand too much (or less forward, these things are relative) then the bow is back heavy and weight needs to me moved forward. Angling the side rods(s) down will fine tune this. Adding weight to the tip of the long rod would be the most affective way to move weight forward (and so removing it is the most effective way to move weight back). What you want to be leery of is adding a bit of weight on the end of this side rod, then a bit more on the end of the long rod, then a little weight on the other rod, . . . ; this can lead you to a bow that is much heavier than before, something that might not be desirable (this is a warning for youths and smaller adults who have less shoulder muscle development).

To get a feel for how the bow is balanced, try hanging it from a hook or loop of cord so it can hang freely. You will eventually develop an “eye” for how a bow that is balanced well hangs. One with too much weight forward will hang with the long rod at an angle that looks “too steep.” One that has too much weight to the rear will hang with the long rod to flat to the floor/ground. From behind the bow, the bow should hang straight up and down, if it doesn’t then weighting of the side rods needs to be adjusted. (This is the only reason for a single side rod on a compound bow—to balance the weights of the “compound weight” bow sight and arrow rest on the other side of the bow.)

Testing, Testing, Testing
We have recommended over and over that when anything new is added to a bow (or the accessories jacked up and a new bow put inside of them), the new rig needs to be tested against the old. Notes need to be taken regarding the arrangement of the “old rig” and some measures of how it performs need to be had (group sizes and round scores seem to work best). Then the “new rig” needs to be set up, adjusted, and tuned and tested in the same way. This is what serious competitive archers do.

Having said this, don’t beat this approach like a borrowed mule. A little bit goes a long way, here. Your first goal is to establish that “this is the way things are done.” You are not trying to establish that this is the best equipment setup in all of the world for your archer. U.S. archer Jake Kaminski has set up a YouTube channel and has made some very useful videos in which he walks through setting up new equipment and testing it. He is an elite archer and has worked out how best to do those tasks for him. You will also see the amount of equipment he acquires and tests, looking for small improvements in his performance. The amount of effort is amazing. Do not try to emulate this as your students are nowhere near ready yet.SAve the elite archer routines for the elite archers.

Bare shaft tuning works well (Jake uses it). Simple testing routines that can be done in a single practice session (or between lessons) should be the goal.

Barebow Arrow Considerations, Part 2

Tuning for a Single Distance

Target archery is becoming less interesting. In field archery, one has to contend with many different shooting distances, different footings, different directions (into the sun, away from the sun, into and out of shade, etc.) and different shooting angles (uphill, downhill, sidehill, etc.). Target archery was a contrast to field archery in that the shooting was on a flat field, at just a few distances and the angle of the sun only changed as the sun moved through the sky. Most rounds had three or four distances to contend with. But, now, as Olympic archery is being driven by telegenicity (make the game simpler so viewers can understand) and dragging the rest of the target archery community with it, competitions have devolved to single distance contests(!).

This came to my attention as I was helping a student prepare for our USAA national championships and he stated that Barebow Recurve was to be contested at 50 meters … only. That couldn’t be right, I thought, so I looked it up. Yep. 50 m, and only 50 m. <Sigh> This certainly doesn’t make things more interesting for the archer.

Preparing for a Single Distance Shoot
Obviously most indoor target competitions are single distance shoots, but outdoors was typically more varied. What this means in terms of preparation is that a number of options are now available for these outdoor contests that were not before. Here are some of my thoughts.

Try to Arrange Your POT Target Distance to be the Competition Distance Stringwalking puts demands upon an archer’s tune so that arrow flight will be acceptable at all crawls. Lots of compromises are involved. This is because taking a crawl basically changes the tiller of the bow and affects the bow’s dynamics. With just a single distance to prepare for, having a zero crawl is ideal. There is also less variation is placing the tab on the string when the crawl is zero rather than, say, a half an inch.

You Can Use a Bottom Nocking Point Locator to Your Benefit If you have a powerful bow, a small crawl may be inevitable. If that is the case, it is allowed to use the bottom of the bottom of two nock locators a set your crawl. The arrow and bow must be set up to make that crawl the correct one, of course. You are not allowed to put on a half inch long nocking point locator, or set your bottom nock locator a half inch below the nock where it would serve no purpose other than being a crawl locator. But for an ordinary tied-on locator in a reasonable position, well that can be used.

You Can Use a Split Finger String Grip String walkers do not use a split finger string grip, they use a “three fingers under” (3FU) string grip because they will be making crawls. But what if your bow is underpowered for the competition distance? In this situation, with no crawl and 3FU, your arrows hit below the target. One easy fix is to try a split finger grip (you may need a different tab). This results in a substantial gain in cast and if your arrows land on the target, you may be able to find a point of aim using either the target rings or the target stand or the wind flag, or … , etc.

A Permanent Fix is to Find Perfect Arrows If the target distance in such competitions is to be the same for many years, it may be in your (or your student’s) best interest to purchase and tune a special set of arrows. After all, you don’t see the long drive golf contestants taking full sets of clubs out onto the tee box. They just take the clubs they are going to use (a pumped up driver and spares). So, why prepare a bow and arrow combination to shoot multiple distances when there is no need. Field archers use arrows with lower FOC balance characteristics than do target archers, who tend to shoot at longer distances. This is just a manifestation of having different arrows for different applications, so this isn’t anything new, just the same response taken to an extreme.

A Perfect Solution Would Be a Dedicated Bow and Arrows It was the case that some archers used different bowstrings on their recurve bows for different distances in the FITA Round. This allowed them to choose different nocking point heights and brace heights for the various distances, essentially creating a different tune for each distance). A lower brace height could be favorable at 90 m but not help at all at 30 m. At 30 m a higher brace height might be a benefit. The nocking points would be used to get the best tune at those brace heights for those arrows (which by regulation had to be the same). I haven’t heard of this being done, but were I in that position and also well-heeled (I am not), I would be tempted to tune my backup bow and arrows, which can be different (both) from the primary set, for the shorter distances and switch bows half way through. Of course if one needed one’s backup bow at the longer distances, one would be in a bit of a fix, but how often does that happen?

So, the message is: if you only shoot at one distance for many of the events you enter (or your student’s enter) focus on setting up the equipment for that distance alone. If you can afford it, dedicate a set of equipment for just that distance. (This is already being done by anyone who has an “indoor bow” now.)

Parallel Shafts and Barreled Shafts: Same Centershot or Different?

I was recently asked by a Recurve student about whether barreled shafts should be set up the same as parallel shafts with regard to centershot. He commented that some expert archers are saying barreled shafts should be lined up with the string (actually the string plane) but parallel shafts should be lined up with the point peeked out from behind the string (the “standard” recommendation for “fingers” shooters). So which way should barreled shafts be set up?

I answered “yes.”

Having the arrow point peeking out from behind the string is the traditional setup position. Let’s look at this. The reason that the arrow point is set up outboard from the string plane is because when a finger shooter releases the string, the string slides off of the fingers (actually the string pushes the fingers out of the way, but “action-reaction” applies: as the string pushes the fingers away, the fingers push the string away). Since the fingers curl in toward the archer’s head, the string slides toward the archer slightly as it slides toward the bow. The bow pulls the string back toward the string plane as it pulls the string back toward the bow and the string slides over to be inside the plane of the bow and then back outside. The nock separates from the string when the string is at a peak in this sideways oscillation (away from the bow, similar to where it started), at least if it is properly tuned it does. The force on the arrow from the string is directed mostly down the shaft and by having the arrow point slightly outboard of the theoretical string plane, then the point end and nock end of the arrow are aligned when the arrow separates from the string. This results in the force being more down the line of the shaft (in which direction the shaft is very strong) and not sideways (in which it is weaker). Force that goes into the arrow oscillation/flexing doesn’t move it toward the target. If you want to see this in action, there is a YouTube video in which a bloke shot a weak arrow with ever stronger bows and the amount of side-to-side bending gets extreme, almost bizarre, before on the final shot (weak arrow-strong bow) the arrow shatters from the side force. (Note: this is why a spine match is so important for “fingers” archers.)

The traditional arrow rest/centershot position for a “fingers” archer. The string has to be visually centered on the riser to get this view.

The argument goes that a barreled shaft is thinner toward the point and when it slides forward to the central thicker section, it moves the arrow point out to the left (for a RHed archer) anyway, so starting from that position gives you twice as much offset and a misaligned force going down the string.

So, is this right?
Yes, sort of … the arrow at brace is sitting fairly close to the thicker center section and so this position is built in, it doesn’t sit with the thinner part on the arrow rest in the position the centershot is set in. When the arrow is drawn, the thinner part slides in toward the bow.

Does it make any difference?
Probably not … for most archers … here’s why.

The position of the arrow rest, which determines the position of the arrow when it is sitting on the arrow rest (the so-called centershot position), is a setup position. When a bow is initially set up, you put things as close to where they will be when the bow is tuned as you can. Why start with wild setup positions which will make tuning that much harder? But since those final positions are determined a great deal by your technique, there is no way to specify exactly what they will be without you participating. So, the described positions are positions that seem to be closefor most archers.

The final position of the arrow rest … and the nocking point, and the brace height, and myriad other settings on a recurve bow should all be determined by tuning tests. If your arrow rest is set so the arrow point peeks out from behind the string (when viewed properly: from behind with the string and limbs free) and you think you might benefit from having the arrow lined up in the string plane because you shoot barreled shafts, then by all means test this out.

Be sure to document your bow before you make any changes. Then measure something that determines the quality of your shots (group size, practice round scores, etc.) and then change the centershot and test again. If these metrics improve, keep the change. If they do not or things get worse, set it back to the position you began with.

Realize that elite archers know their equipment better than most archers. They may have starting positions they use for their bows that are very, very close to what they will be when tuned in. Most archers need to learn more before they will know what to expect, so minute information gathered from the elites is probably of not much value.

Also realize that there are many, many variables involved in tuning a recurve bow to a high level: nocking point, string material, string diameter, serving diameter, nock size, the archer’s tab, the brace height, the limb alignment, the stabilizers, nock size, … <pant, pant, pant> … , the quality of the limbs/riser, the button position, the button pressure, … , as I said, myriad things affect the tune. Interestingly, a good basic set up of a recurve bow gets you 90-95% of the way to where you will be at the end. Tuning takes a great deal of time and a great deal of effort for that last 5-10% of performance. We are saved because of a basic rule which is: you can’t tune any better than you shoot, so for most archers, little tuning is needed. Since the elites shoot so well, they have to tune the heck out of their bows. They are, after all, looking for the last fraction of a percent of the performance they can get from their equipment and the law of diminishing returns applies.

Barebow Arrow Considerations

There is an upsurge in interest in Barebow, both Recurve and Compound. (Yeah!) This is accompanied by increased levels of confusion regarding the role the arrow plays in the ability to shoot consistently.

Since there are many Barebow aiming variations (gap shooting, “instinctive” shooting, string walking, face walking, etc.) I am going to hop over these variations (all of which create tuning issues) and move to the heart of the matter: aiming off of the point.

Aiming Off of the Point
Using the arrow point as an aiming support brings many advantages and a few disadvantages. One disadvantage is it makes draw length even more crucial. For example, consider that the nock end of the arrow is below the aiming eye and the sightline. The line of sight being even with the arrow point means that the arrow is slanting upward (as it is with other styles, of course). Now, if you draw your bow a bit too far, the arrow slides back and downward lowering the arrow point, causing you to raise your bow up to get the point back to the sightline. Drawing your bow a bit long results in high arrow hit points in that you’ve made the bow a tad stronger, but raising the bow also contributes to high arrow hit points, so this “positive feedback” results in larger errors. Similarly, a short drawn bow, results in the arrow sticking out and up farther, which results in you lowering the bow, another double whammy! (This effect is prominent for longbow and recurve archers, less so for compound archers.)

Aiming off of the point makes draw length control particularly crucial. On the plus side it provides amplified feedback in that regard and so may contribute to better draw length control. There are many other aspects of aiming off the point we leave to your further investigation.

The Effect of Arrow Length
The effects of variations in draw length can be made permanent by choosing a shorter or longer arrow. A longer arrow will result in a lower hold of the bow. A shorter arrow will result in a higher hold. So, for indoor targets, a longer arrow can be an advantage. Indoors, the distances are so short that most bows are over-powered. This results in points of aim (POA) being very low, off of the target face and maybe on the floor where there are few visual clues as to where the POA is. We would like to have a POA on the target face as a face provides many visual cues as to the POA’s location (e.g. a POA at 12 o’clock in the 5-ring). So, for indoors, most people favor a longer arrow. This cause the hold to be lower and the POA higher. Since the length of the arrow is one of the largest aspects affecting the tune, a stiffer shaft has to be chosen to compensate for the extra length.

Outdoors, the distances are much larger, and bows tend to be under-powered. Here a shorter shaft provides a higher hold, a lower POA, and more cast, but we need a weaker shaft so we can cut it as short as we can.

We accept as a given that one’s form will be more consistent when the arrow is near level than when the bow is held with the arrow slanted way up or way down. So, the closer you can create a setup, for you or your student, that is near that situation, the better.

Arrow selection is not a simple matter of just checking a manufacturer’s spine chart and selecting the shaft closest to the characteristics your archer possesses (DW and DL and bow type). In most spine charts, the entire row of choices determined by the DW are available to you. Limited only by arrows that are too short (as they are dangerous). Here is a row from a simplified spine chart:

Compound Bow

21˝ 22˝ 23˝ 24˝ 25˝ 26˝ 27˝ 28˝ 29˝ 30˝ 31˝ 32˝ Recurve Bow
29-35 lb 1214 1214 1413 1416 1516 1713 1716 1813/
1816
1913 2013/
1916
2013/
1916

17-23 lb

Assuming this is the correct DW row, if the archer’s draw length is 24˝ AMO, a 1413 aluminum arrow is recommended. Shorter shafts are possible, but remember the arrow point is typically only about 1.75˝ ahead of the arrow rest at full draw, so a 1214 shaft could be used, cut to 23˝ but I wouldn’t go shorter. Other choices are: the entire rest of the row:
a 1416 shaft, cut to 25˝
a 1516 shaft, cut to 26˝
a 1713 shaft, cut to 27˝
a 1716 shaft, cut to 28˝
a 1813/1816 shaft, cut to 29˝
a 1913 shaft, cut to 30˝
a 2013/1916 shaft, cut to 31˝
a 2013/1916, cut to 32˝

All of these shafts and cut lengths should produce arrows of comparable performance. Keep in mind this is not this simple. As we move across this table row, the arrow shafts are getting heavier and we are losing cast thereby. (There are other issues, but this post is too long already.) All parameters in a spine chart, therefore, need to be taken with a grain of salt and if you desire to experiment with different length arrows, always (Always!) start with a longer shaft and cut it down in stages, testing for tune as you go (a bare shaft test is all that is necessary).

A Note Regarding Young Archers
Archers who haven’t achieved full growth probably should not play around with these ideas. For one, they are still growing and as their height increases, so does their draw length. Ordinarily I like to have at least 1˝–2˝ of extra length on their arrows just for safety (and the ability to shorten the shaft to get a better tune as they grow). These youngsters are better off working on their fitness and shooting form and execution than fiddling with equipment to get a slight advantage.

If a youngster, however, is having trouble “making distance,” the problem may be exacerbated by an arrow that is too long. I have seen some sticking out more than 5˝ past the back of the bow. In this case, a better fitting, resulting in a shorter arrow should help.

The Ins and Outs of Bow Presses

If you want to be a compound coach, do you need a bow press or at least need to know how to use one? I think the answers are “yes” and “yes.” Compound bows were invented before the bow press. In those early days (the 1970s and 80s), it was the practice that to work on a compound bow, you slacked the string and cables or even dismantled it by backing out the limb bolts. This was a clumsy process which could be dangerous and, for one, screwed up any chance of finding your previous bow setup and tune accurately.

For those of you not in the know, compound bows use mechanical advantage to bend very stiff limbs, very short distances. In those early days, again, there were even kits to convert recurve bows into compounds: they involved cutting off the recurve sections and bolting on wheel hangers, etc. These bows, even without their springy limb tips were invariably weaker than purpose made compound bows, which used much heavier limbs (over 100 pounds of deflection force at a minimum).

Technicians in shops and manufacturers responsible for assembly, repair, and adjustment of these bows quickly realized the need for a device such as a bow press and voila!

The photo shows a couple of common modern designs, the yellow one was designed for older bows, the other for more modern bows. The yellow one worked until the past decade or so. The bow was placed so that the limbs rested on the outer rubber rollers, which were adjustable to make a correct gap between them. Then a winch pulled the riser, which was hanging below, downward, causing the limb tips to bend closer to one another, slackening the string and cables (see photo at bottom). The original presses were more like the yellow one, but they involved a single center pull (at the pivot point of the bow). It only took a few dozen bent or cracked risers (they were wood or cast, not forged, aluminum then) to suggest the improvement of having a double pull (note the two central rubber wheels on the yellow press), this perfecting the design.

That design lasted until compound bow’s evolved toward what are called “parallel limb” designs. These bows have limbs that are parallel to one another or even past that point. The original design of bow press no longer worked because the limbs didn’t stick out far enough to get bent; the bow just pulled through the outside rollers!

The other bow press has “fingers” that approach the limb tips on both sides of the eccentric on both ends of the bow (see detail left). Then a screw drive (powered or manual) brings those two ends of the bow closer together, getting the job done. This new type of press will work on newer and older style bows as long as the bow is short enough to fit between the fingers! In the early days of compound bows, the bows weren’t short like they are now. Instead of 30˝-38˝ axle-to-axle bows as are currently in vogue, they had 48˝, even up to 54˝, axle-to-axle bows. Modern bow press manufacturers are unlikely to make their presses accommodating of these very long compounds as so few still exist.

This press was my first press. I still have it as I have quite a few older bows.

Danger! Danger, Will Robinson!
Using a bow press is inherently dangerous, so be sure to get a seasoned veteran of their use show you how to use one. The forces involved are great (hundreds of pounds of force) and, trust me, if you make a big mistake, changing your underwear will be the least of your worries.
