A very clever animation and a fascinating bit of machinery. I hope you enjoy.

Superb animation, thank you for posting it. We had a good look at the S&L cut rifling machines a few years ago, they are probably over 100 years old and still producing superb barrels. I asked about the depth of cut per stroke and the owner told us it was so fine it could be calculated but not measured.
