Good thinking, Batman. This was the first one I found and seemed straight forward enough so I gave it a go, resized to allow for the shallower capacity of my lathe. Was going well till I mounted them to the chuck assembly; higgeldy-piggeldy barely does it justice. Thought I could maybe use the lathe to true things up a bit and watched from behind my face guard as one of the better looking jaws went into orbit! Back to the drawing board.marcros":2hxuoc0g said:Have you thought about marketing a set? Various videos on YouTube doing so.
