Customized Hoyt Matrix

gah..i cant see the final pics.

but the preceding ones are awesome!!

have you seen Randy Ulmer's Matrix? he drilled (i think) holes in the riser and mounted his fall away way in the back..so he essentially made an "overdraw". he shoots these tiny, short arrows! i tried freezing the show to take a close look at what he did, but it was difficult to see.
 
Looks great Justin ! To get this straight , you painted that , not a wrap ? Is this some kind of stencil if that is a paint job ? I've gone with Asat as a camo and that would look cool on a rifle I think.

Not to get away from the thread but PM Rodney, Athens Archery will dip your rifle or bow, I'm getting my sako done in highlander.

Yea I went with duracoat painting because I was worried about how a dip would hold up on the carbon riser. I think for aluminum risers dips are the way to go. But carbon riser makes it tough to find a finish that lasts.
 
I have seen that before! Kinda crazy!

I don't get why he does this?

The purpose of over draws was originally to shoot lighter arrows? Not needed with today's carbon arrows. Plus light arrows aren't that great for hunting anyway. Plus I think having the arrow behind your hand would magnifiy torgue or operator errors?

Torque and torque tuning. Nothing to do with speed or shooting shorter arrows. I think Randy leaves his at a standard length for traditional rest mounting. It takes some experimenting, but rest position farther back can ruduce the effects of archer induced torque.

Really? That's interesting. There are two schools of thought on this subject. One is the rest further back helps with torque. The other school of thought is it magnifies torque!
I'm gonna look into it. Might be making another mod to this bow. Haha

Can you explain that in a bit more depth?

If you buy a7" brace height bow, stick a 4" overdraw on it, wouldn't that make the brace height 3"?

We've jacked around with this a lot, and I've never seen a bow with an overdraw outshoot one without.

I'll give it my best shot. Technically the brace height doesn't change. That's a measurement from the string to deepest part of the grip. The only thing that changes is the contact point of the arrow on the rest.

This method is gaining a lot of use in the target venues. Considering Randy's background, and OCD tendencies, I'm guessing that is what he is doing. The theory is that changing the position of the pivot point (arrow contact position on the rest) can influence the effect of naturally occurring torque. By sliding a rest in and out, and shooting the bow normally, and with intentionally induced torque the sweet spot of the pivot can be located. This is the place where the arrow varies from its intended path the least when shot normally, and with intentionally induced torque.

You can see it without shooting. Draw the bow, see where the tip is pointing. Torque the bow in and out and watch the tip. Move the rest, repeat. The tip may move more, or may move less. If it moves less, its an indicator that you are getting closer to the sweet spot. The distance of the OD varies from person to person and bow to bow. Find the sweet spot and minimize the effects of the torque, and the arrow flies where you want it to easier. From shot to shot, archer induced torque, including the effects of fatigue, are minimized. That's the theory. Arrow length are usually left 'normal'. It is also similar to 'node' tuning.

Again, something being used in the target venues where relatively small spots by comparison to critters are being shot at distance for $. For hunting purposes, for most, probably not a huge issue, unless you have severe OCD tendencies.
 
I'm am by no means an expert on bows or bow tuning. But thinking about this from a physics standpoint if the bow wasn't actively twisting (but maintaining its angle) during the release it theoretically wouldn't matter where the support was, the whole thing still pivots around your hand. I realize that the bow probably rotates during this time hence longer brace heights generally being more forgiving. As I was thinking about it I did come up with one possible theory as to why this could possibly produce more accuracy. If you move the support point back, you may be changing the amount of deflection of the arrow. (Increased cantilever shorter span) I would guess that you could theoretically "tune" your bow to produce the best arrow deflection (harmonics) if you could infinitely adjust the rest. I am not sure if it could be isolated enough from all other factors such as bow tuning, arrow inconsistencies, form etc etc to make adjustments and improve it.

Just a thought

As if archers need another almost imperceptible thing to fiddle with indefinitely.

Yea that makes sense. I know it has been an interesting subject with arguments on both sides.

There are a lot of pros that shoot overdraws so I'm thinking they know something and obviously do it because it betters them.
 
Best looking bow i've seen. I've duracoated a few bows. I holds well. Lauer weaponry also sold some stencils that i thought would work. Did you add the flex agent?
 
How does the bow shoot? I may be able to pick up a 2012 Carbon Matrix RKT used in excellent condition. I have only shot the new Hoyts; the Carbons and Faktors; and love how they draw, point and shoot.
