Slap or snap!

[squid]

Ok, a friend of mine that makes longbows decides to try his hand a recurves. He gives me his first one and wants me to be his R/D person on the bow. I shoot it and first thing I heard upon my release was a slap or snap. So this is what I have done with the bow to try to get rid of the noise.I have shot three different spined arrows and no change in the noise. I have adjusted the brace height from 7.5" to 8". No change. I have moved the nock up and down in a 1" range. No change. I replaced the felt in the string grooves with thicker felt and wrapped the string ends that contact the limb with felt. No change.I put limb savers on the limb ends, no change.I put felt on the edge of the shelf facing the shooter, no chage. The only way to describe the noise is if you were to slightly hit a carbon arrow on the edge of the limbs is what it sounds like. I thinks the noise is loud. He stacked the limbs and it has narrow limb ends(1").
I beginning to think that the noise is the limbs actually snapping back when I release it.
I'm new to the trad world(3 years) so I was wondering if any of you ever heard of a bow's limbs snapping back and making the noise. It's a 62"@48#. Everything I had done the noise never changed tone or loudness.
Thanks

Ask this in the bowyers bench on the main page. Oh and are the limbs equal when drawn?

One piece bow?

Without hearing it , it is difficult, but that sort of sound is often the arrow nock or rear end hitting the bow as it passes.  Needs more tuning.  Try spraying "dry" deodorant or similar powder stuff on the bow in front of and in back of the rest.  Not just the bottom, but also the riser sides.  Shoot and see if any marks are left there.  That may help rule out or point to something.

Are you certain it is the bow ?  Not the string slapping your sleeve or arm guard, or your tab snapping from the laser speed of string release : )

How tight are the nocks?

Lots of things can cause that noise.

Yep. Point bow at ground w/nocked arrow and lightly tap string. Should fall right off.

Maybe try a different string material.I have bows that are quieter with D97 some with 8125 and some with 450+.Just a thought

Had a sound like that,ended up it was my wore out shooting glove snapping.

Does your strike plate appear to be wearing too fast?

I went through the same thing this last week and it about drove me crazy. Changing the string material solved the problem for me on the first shot.
