I think I still have some yew lams stacked up that I milled years ago. I personally didn’t care for the lams much myself for glass backed bows. It’s kind of oily material.
I got better performance from old growth doug fir for glass bow cores…. I’ve still got some of those lams milled too, but haven’t used them much in recent years. I pretty much stick to maple and bamboo core woods for longevity reasons now days.
Now if a guy was to get serious about building some laminated board bows, I think this yew would probably work well with some natural backing of some sort. I bet you could use a maple or Ipe belly, with Yew back, and get some good shooting bows out of it. Kirk
