this is my second attempt on a recurve , this time its a nice piece of elm that ive found. i have it down close to the final tillering shape after heat tempering the belly and the one tip, about up to a foot in, is twisting a little out of middle. i was wondering should i file some of the wood off of the side that the twist is tending towards? or should i possibly try to bend it with dry heat again? i dont want to heat too much if it is possible to make it weaker after a point.
