I eventually got black cherry, that I cut and seasoned myself, to work well by backing it with 1/16" thick quartersawn hickory. I glued them up in a gentle overall reflex. 1 5/8" wide, 68" long for 28" draw. Radiused bellies too, just my preference. Cherry is feather light and lively wood and doesn't take much set if designed and tillered well. But cherry will test you. It's demanding enough of us as it is, so I think using a board from wood that we don't know how it was cared for from the time the tree was cut, potentially raises the risk of failure a bit more... as it does with most woods I guess. That's why I like to cut my own.
I tried to post pics of cherry bows but had to resize them so small for this site that they looked like crap. I'm not posting them like that. Sorry. How do you guys post decent pictures on here?
