I have a stave I cut early in this journey that I've since learned is unlikely to make a bow but I decided to see how far I could take it anyway, for practice. It had a bad twist in one limb that didn't get any better as I began tillering so I figured, more practice for an "advanced" (for me!) technique. I heated it over a pan of water on the grill and Whaddaya know, it seems to have worked! So far...

My question is how long to wait before unclamping it? It's cool to the touch but should I leave it overnight to be safe?
