Well, dang. Several attempts ended in failure.
Used bacon oil and dry heated the wood - first attempt, got it nice and hot on the belly, but not scorched - hot enough to feel heat through to the back - put it in my caul and let it sit overnight. Next morning, released it from the caul and it sprung right back to original shape........
Tried it again, this time with more heat (enough to scorch the belly and the bow was very hot to the touch)... put it in the caul, next morning pulled it out to find the back splintered.
I need to check my thinking - if a bow is seasoned and dry, dry heat seems as if counterproductive. Not enough oils in the wood at this point, is there? Can someone explain the reasoning behind the concept of dry wood = dry heat / wet wood = wet heat? Seems as if it should be the opposite. Just curious.
Thanks.
I'm not giving up on russian olive just yet - starting another, this time a D-bow (staying on the simple side until I'm sure). Its too perdy of a wood, and seems quite strong.
