I managed to get a good string alignment on my recurve but now I want to heat treat it. I've lost string alignment before due to heat treating. Is there any tricks to keeping it straight?
-
Only thing I can think of is clamping it down during heat treating and waiting a day or so to unclamp.
-
I've tried that and I think either my clamping or just the reheating of previously tweaked puts different stresses on it and when you undo it, it moves. I guess I'm going to have to figure a way to hold it without clamping it too hard. This one has siyahs so if gives me a uniform shape to clamp so maybe it won't be too tough. This has been my stumbling block with recurves. I spend more time with a heat gun in my hand then I think I oughta.

The thing about recurves is the more you put the tips behind the back the fussier it is to have them dead nuts aligned.With reflex in limbs or degree of static your working with.A deflexed limb with recurves is a bit easier for alignment.Like Jeff said clamping it in place is the best way.Always more work and time with making a recurve.No getting around that.You just keep tweaking till you get it right is all.Look forward to seeing what you get done.

I've found a lot of tweaking with recurves and especially with any change. After the heat treating just reheat and make the adjustment. I'd suggest adjusting each limb independently and readjustment the bow for a final profile.

+1 No quick answer... just repeat until it's right or your patience gives out >:D

The only trick I can suggest is to do the heat-treating before you do all that tip alignment ;D

Marc that makes since to me. I'll try that on the next one. Arvin

Yup. I leave the limbs on my bows at least 1/4 wider than my end goal until after heat treatment. Much of my final tillering happens from the sides of the limbs, and I use it to reach final width from the fades all the way out to the tips.

I do it all in one heat on one caul. Seems to work out nearly every time.

Flex your recurved blank and and make note of which way it is showing it wants to twist. Heat treat it in a slightly overcorrected shape and you'll be very close.
