Warning... grumpy post!
"Someone asked me to"
Yeah, there is no shortage of idiots... I wouldn't spoil a good bit Yew (mind to be fair I'm probably working with Yew that others would consider marginal in the first place)
But if you have some with bad sapwood maybe try it.
More than once I've made a customer what he thought he wanted and it failed, whereas If I'd been left to my own devices they'd have ended up with a fine bow
.
During my working life I found that what the customer thinks he wants wants and what he actually needs are two entirely different things.
I no longer make bows for idiots
