[TheForge] Krause/Nazel type air hammer

Sun Dec 1 00:30:01 2002

Steve and Mike,
I have built a nazeloid based on Mark's design and help. I need to enlarge
the ports, but otherwise I belive it will work like Mark's. If intereted,
contact me off the list if you have any questions. I am not expert ,but I
have made plenty of mistakes to learn from.
Bob
