[TheForge] Krause/Nazel type air hammer

Sun Dec 1 12:15:00 2002

Bob,
Many of us would like to see pictures and info about your  hammer.
Please post to the list and the photo site--thanks.

I was surprised that there were no examples of home-made
self-contained hammers at the ABANA conference in LaCrosse.
