Speaking of specialists, wwh, what haven't you done in this life? I ask a simple question about chatter marks, and learn that you have, among the many things you've done, made your own baseball bats from scratch, and, as if that weren't impressive enough, learned your father made a cannon from--what????!!!!--an axle, and let the thing boom off on a common.

Uncommon life, yours! I'd love to see a list of everything you and yours have made.

Best regards with utter amazement,
WW
