Be careful not to overdry yew. It'll explode, even if the tiller is perfect.
There's only ONE bowmaking do-over I wish I could have, and it was a yew selfbow... the style you're talkin' about. It was a thing of beauty, tight growth rings, perfectly clear wood, backed by its own sapwood in a single growth ring that I chased forEVER, white horn tips, done, tillered to 28", shot in, still showing a little reflex... then I forgot it in the drying box, for a couple of months actually, and it blew up as I tried to brace it. I was sick... and it still bothers me now thinking about it.
I should make another just like it.
