Heat treat maple... when?
« on: July 16, 2013, 10:39:48 am »
I have a hard maple stave down to floor tiller.  I plan to flip the tips and heat treat the belly.

I haven't put a long string on it yet, my question is: Should I flip the tips and heat treat the belly in the same heat treatment?  That's what makes sense to me as cooking the belly after flipping the tips could remove some of the "flip" unevenly.  I don't have to flip the tips, I just like the way they look.

Should I tiller it out by bracing with the long string first before heat treating?

It's pyramid shape flatbow 62 1/2" ntn, shooting for 50# @ 27"

This will be my second completed bow if it survives...

I like to heat it now before I string it, and then possibly again before I finish it.  Never heat treated Maple, but other white woods yes and Osage.  Flip and heat treat IMO.  I have read where others just heat treat once and that's it.  My best results with white woods is to heat early and then again if I take it down to fresh looking wood.

I usually heat just to straighten and line everything up,then tiller to 16 or 18 inches,then heat treat [kind of] with added reflex,after the heat treating then if I am flipping the tips which I usually do,I will do that,then give it a few days to re hydrate and then finish the tillering. :) Seemes to work fine with white wood. :)

what Pappy said...............Just make sure to let it rehydrate for a few days or you might get some frets/crystals, or worse.
