Title: Reverse Taper
Post by: Craig Warren on April 12, 2008, 10:43:00 AM
Can someone tell me the reason for adding reverse tapers to a one piece recurve form?  I've made quite a few 3-piece recurves and 1-piece and 2-piece longbows, but am about to cut our a form for a 1-piece recurve and am curious why it is recommended.
Thanks, Craig

I think it has alot to do with different bow designs.Like 21st Century,they used a reverse tapered lam in all their bows.I have had a few others with a reverse taper.I believe it helps to stiffen the tip end of the limbs,making faster bow with less handshock.Most of the bows I've seen with a reverse taper were in longbows.

I believe it is to compensate for the tapered laminations used in the limbs.  Adding the reverse taper to the form allows the riser section to fit with the tapered limb lamination between the riser and the form.

Craig, did you mean, on the form or in the bow make up??
   I thought you were asking about a reverse taper on the form it's self not in the limb of the bow.

On the Bingham recurve,when you cut the strait line on the form in the riser part,then glue-up the bow with .002 tapers,the handle section overlays won't fit quite right,only reason I can think of.....

Shaft Slinger, yes, in the form.

Kennym, I can see what you are saying, but I've never used reverse tapers in my form and have never had a problem.  

Thanks for the info.
