Mike, I hear what you're saying. I've got an email in to Mr. Adcock. If he doesn't respond, or can't help me, I'll see about having someone else do them.
To me, the biggest pain will be building the form. The rest should be straight forward. The pins aren't centered, but it looks like it would be easy to make a pattern off the existing limbs. Heck, a person could even grind off the old ones and put in new.
I don't think the limbs are made out of any top secret materials, either. It looks like bamboo cores, bamboo veneers, and clear glass. The wedges look like ebony. The tip overlays are micarta.
I'm just about talking myself into building them myself. I just need to get a bandsaw and a sander.
