Gordon:
What PD said, reduce thickness to remove the fractures and add a lamination if necessary. You can tiller a bow before making heat corrections. I do that all the time because it is much easier to bend wood when it is near final tillered dimensions.

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.

That’s what it looks like to me too.

I usually reduce to about 3/4” maybe 1” at most.

Like Pearl said for recurves I use steam. The thicker the longer. Usually about a hour. I also have everything I need waiting and ready when I pull it out of the steam.

For dry heat it I hold heat gun on area to correct until I can feel the wood gives up and it willingly goes where I want it to. You can feel it.

If it doesn’t want to go I don’t force it. I either put it back in the steam or hold the heat gun on it longer.

For recurves I also use a thin metal backing strip that helps hold grain down. A d shape cross section helps and also chasing a ring on belly side where recurves are going to be bent.

PEARL DRUMS:
Next time you need to bend some wood try to get it hot enough before you add weight and/or clamp it. By hanging 10# on it before hand you are asking it to start bending under that weight before it truly is ready.

DV IN MN:
Thanks for the info. I did rasp/sand to below the frets. It is now 1/2 deep by 7/8 wide at that point and we will see if it will work or if more compression damage is deeper than visible.
