Thanks, guys.
The White Ash I used was a 7-foot plus seasoned log that my uncle bought to cut up for firewood. It yielded my first two self bows and one stave I mucked up and one stave I cracked (just last week) trying to straighten a limb twist.
It doesn't have borer marks all over it?
My grandpa tried to tell me he had some ash he could cut and give me for building bows. I saw the particular trees he was talking about and the ash borers had already gotten to them.
If your uncle bought this as firewood, it is
very likely that it was cut standing-dead and already had ash borers in it.
If the last ring is marred up it's not going to work. Chasing a ring might work, but frankly, I wouldn't even mess with it.
If it was alive and unaffected by the bugs when cut, well, then that's a different story.
I've made an ash bow from a sapling, and have a few others that I'll do the same with.
