Some Do, Some Don't

Not being much of a formal target shooter (try not at all), I've had to learn what seems to work and what doesn't by experimentation and research. Having tried several types of wood and metal recurves, I settled on an alloy-risered bow, but noticed a trait that seems common with target-derived recurves: the bow recoiled as if top-heavy. Despite adding weight at the bottom limb attachment, the upper limb still came back toward my head upon release.

I've finally built up a modular stabilizer primarily of Sims components, which extends out nearly 12", and the bow is now slightly nose-heavy. Recoil is straight and forward with a wrist sling, so I'm not clenching noticeably, though the complete setup looks a bit odd. Some people have talked about adding various devices like bowquivers of different designs for the same purpose, one guy rigging a bracket that holds the quiver directly in front of the riser instead of along the side, another turning the mount upside down to put weight toward the bottom of the riser. I'm curious as to whether anybody else has run into this problem, and what your solution for it might be.

Interesting pictures there. I would say you have made a short "longrod"... Poker in the U S I beleive.
The longrod has a tendancy to stop the top limb from coming back to the head You can always add weight to the front of your prod for balance. Take a look at http://www.tenzone.u-net.com/Equipment/index.htm that might help somewhat

Very interesting reads, thanks! Figured I was going along the track of somebody else's experience, just didn't have the data at the time. These sites are just about the only sources I have for modern techniques and kit, so anything is appreciated.

Thanks for posting that up steve , I like to bow setup, but I must say that I am not familar with the problem you are talking about. Maybe I am lucky on my recurve but that has always behaved as it should and feels great in the hand to boot. Nice to know you have your 'curve going well

Seemed odd to me, but I've been told it's a common phenomena with long-risered target bows, and is one reason you see those looooong stabs in competition. Something about hand/grip placement relative to center-of-mass when the arrow is released, and a bunch of other rubbish I can't remember now.

All I have on my rucurve is a small weight in the bottome limb bolt, and it doesn't kick back at the top. Does that mean my bow is different ( Just like me )

Nah, just means I'm out of kilter with the world in general. Cool baby, like tilted.

I'm a barebow recurve shooter and all my bows (aluminum risers) are ballanced to hang straight up and down in the hand. Upon release they jump slightly forward, until caught by the sling, then just hang there vertically. I don't see the need for the radical forward rotation the FITA/Olympic recurve types seem to prefer. YMMV!

There seems to be a desire to have a forward tilting bow for some reason, never understood why really even though I had it with my recurve and currently with my compound, I suppose its an obligitary side effect of having a stabiliser up front.

Just thought I should add this. David Barnes who is one of Australia's best recurve shooters has been heard to say that the bow tilting forward radically does nothing for the shot because the arrow has long gone. But it looks so cool when it happens on the shoot line.

So basically it is for us not the bow or the shot itself. If we think about it our recurves should be going about 200 - 220 FPS. so when we let the string go the arrow will more than likely be clear of the bow in say .4 of a second ? we are not that quick to affect the arrow flight so the stabiliser is for the stability of the bow during the aiming process and after shot reaction. Maybe I am being to clinical but had to say it anyway

I quite agree with Steve. The main part of stabilization is to aid the archer with the feel of the shot and assist in aiming. Assisting the archer in replication of the shot and that is why some archers like a lot of forward weight and others do not.

Setting up a bow to fall forwards is simply a case of making the shot feel more positive towards to the target. It will feel far more positive and aggressive towards the target to have a bow that travels flat out of your hand and falls away in a controlled way than one that leaps up and flaps about aimlessly. I know which bow I would feel more confident in shooting.

However I also believe that stabilization also helps the archer during the shot in assisting them in controlling the bow. As the string is released if it is not done perfectly we introduce small errors (or large ones on occasion), and the bow will want to twist and turn because of these errors. The mass at the end of the stabilization helps dampen these errors by resiting the movement of the bow helping to make the shot a little more forgiving.

Yep - it does seem to be considered desirable with target recurve? I sort of agree with the point about it being a "side-effect" though - I always thought that the longrod - which puts weight waaaay out in front of the bow - was mainly there to reduce torque - because the weight far out at the front has inertia and stops the bow twisting in the hand. Can't really see how the "roll-forward" contributes anything to the shot - the arrow's long gone by the time it happens?

EDIT: - Sorry Steve B, read your post afterwards (DOH!)

At least we can say that we agree Cypher
