longworth chuck
I always ran into the problem of trying to hold finished parts without screws or marks from a chuck i came across this longworth chuck design it works good and simple to make i used cam clamps instead of wing nuts to tighten holds well at low rpm and light work next project to make one for my rotary. splinter
