Heat correcting twist in recurves...
« on: January 05, 2013, 06:30:24 pm »
I'm currently making a, soon to be, rawhide backed osage. It's 60" ttt and will have a mollie style build to it. I normally get a wee bit of twist while recurving the tips, this one seemed to twist quite a bit more. Any tips on how to fix this? Thanks in advance.

Best way to do it is to overcompensate before hand, I have the same problem as you with my recurves alot of the time. What you do is, make sure you leave a good amount of extra width so that you can just remove the excess to get a good alignment friendly recurve after bending incase they twist or go to the side.

EDIT: Also, for your problem at hand, I suggest googling heat bending or heat correction, and I am sure you will find some good info. I personally can't help much in that department.

 the upper part is pressed down,
 the lower part is raised up,
 the part that has too much is reduced,
 the part that has too little is increased."

I'v never done this but from what I understand, maybe just heating it up enough so you could twist it the other way would work?

I can generally carve out the twist. I think I can clamp it to my bench and heat bend it enough to get it to where it's livable.

Generally when I'm making a recurve I have to adjust the tips a few times. I also leave the tips wide and I can make adjustments by situating the tips by removing wood from one or both sides.
  Have you rawhide backed the bow yet? What glue did you use?

No, I haven't backed it yet. I haven't done rawhide before but, with sinew backing, I get the tips recurved how I like and then add the backing. I'm going to be using TBIII. It's done me good for snake skin, sinew, etc. I think I'll stick with it.

I think I found the ticket. Stuck one tip in the vice, heated it up and pushed it until it realigned itself. Easy deal, the tiny bit of crook/twist left will easily be carved out. Thanks for the info fellas.
