I think the most fascinating piece of equipment I saw at the BAM conference was a helve hammer made by Bernie Tappel. He made it since the last conference and I think this was the public debut. He said he made it almost entirely from scrap he had on hand.
I’m going to study it and see how something similar might apply to my work. It looks like a very appealing engineering challenge. As Robert Oppenheimer said, “It is a technically sweet project.”
I hope Bernie will write an article for the BAM newsletter about it.
