No way?
It can be done. I've done it on each yew bow I've made, with very few violations.
I'm working on a yew elb now. I thinned the sapwood and chased a single ring from end to end. I don't believe there's a single violation in it. It's quite thin ringed high elevation yew. I'd guess 60+ rpi. It probably took me as long to chase that ring as some folks spend on an average whole bow's construction

But I'm glad I did it. She's shur purdy.
