twisted limb on a board bow
« on: March 14, 2010, 03:39:00 PM »
i got a longbow kit that is, ipe with a hickory backing. after i glued the backing on i notice the the ipe had a twist in it, i knew it wasnt good but i keep going anyway. well after i got the limbs cut out you really notice the twist in the limb now. (my limbs are a little too narrow so thats not helping) is there any way i can get it out ? i thought about trying to soak the wood or putting some steam on it and twisting it the other way. or should i just put it in the trash.

Heat/water/steam and glue don't go well together. Maybe you can take it out messing with the tiller?

You can heat up the backing strip and the TB glue will release at 150deg (F). I did it with a heat gun.I started at the tip and worked a chisel into the joint and separated it as I heated down the bow. Then you can clean up the surfaces and re-glue it up untwisted.

Also, Ipe, like other tropical woods don't react well to heat, wet or dry so trying to straighten it with heat is ineffective.
