Toasted or toast belly frets

(1/4) > >>

DV IN MN:
So I heated the osage stave adding curved limbs to match the natural curve of the other end. Ended up with some pretty severe belly frets. I can try to super glue or sinew wrap them also. I assume the sinew wrap would save not sure on the SG. If I take it below the frets depth the recurves will then probably be working recurves. Probably 1/2 of depth would be left if I removed to get what looks to be below the depth of the fret. Any thoughts?

Depending on your length and style of bow you may be able to get away with 1/2” thick recurves.  Lots of factors to consider.  Those look pretty deep and would suggest a moisture issue or too much concentrated heat.  Did you use steam or boil the recurves?  You may have had some excess moisture to cause these cracks or frets.  Sometimes with steam I’ve seen the rapid loss of moisture cause these sort of cracks.  Also another thing to consider is keeping to single grown ring on the belly wood at the tips to help prevent lifting of cracks.  Depending on the draw weight you are hoping for you may be fine with 1/2”.  If not you could also consider a belly lam to strengthen that area to withstand the force and hold its recurve shape.  For frets this big I would hesitate on ca glue and wrapping.  It’s hard to say with out more info but would lean more towards a lamination    Hope this helps.  Good luck

I believe its from trying to bend too thick of a piece with not enough heat. I would get down below them and re-bend it, add a lamination if it gets too thin. The wood wasn't hot enough to stretch as far as you intended. Thick wood bends are best suited to steam rather than dry heat. That's my .02 cents.

DV IN MN:
Reason I did what I did was since the other end had a natural recurve on it. It was at slight floor tiller. Did this since couldn't start the tiller process until both ends were the same. used heat gun and put 10 lbs of weight hanging off the end and when it was hot enough that the weight pulled opposite limb to resting on the cull then I clamped it down.
Moister? it is a 30 year old piece that has been inside and pretty dry in MN this time of year. But maybe. 
This was the second heat app the first one did not have enough bend so applied heat again. Should have left well enough alone.
Trying for weight in the 60's @ 29" draw 64 in. TT.
