I’ve started thinking about building a helve hammer when I get the time. I’ll start by doing the design drawings and that way I have some definite ideas in mind so I can collect potential components.
I began by studying the images I took of Bernie Tappel’s machine and making a parts list. Next I did some searching for other design variations. Eventually I’ll put something together that seems to best suit my needs.
The following list if some of the things I found about helve hammers on the web which seemed must helpful to me.
Richard Ferguson’s Excellent post that covers almost everything about helve hammer physics.
