maitus I posted the Elm bow for you to look at ,and maybe try the next one this way if you are getting excessive set with Elm. This bow is 60 inches long 44lbs at 25.5 inches draw, and has 1.5 inches of reflex. I get the bow down to past floor tiller,and put it on a form. Then straighten with heat, and clamp as you go.Then I give it a deep belly heat treat before it comes off the form. Then tiller with a gizmo to 20 inches on tiller tree. If it is holding it's reflex I tiller an inch at a time to my draw length, and target weight. If at any time it is not holding it's reflex I heat treat the belly again. I may heat treat the belly 2 to 3 times in the process. Elm takes good to heat. Then sinew ,and hang the bow to dry with a 15 to 20lbs of weight on the middle of the riser, and let the sinew dry a couple of months if you want to sinew the bow. Elm will make a good self bow also. You do excellent work. This may help a little with your next Elm build. good luck.
