What do you guys use for holding a ring accurately while turning it
in a lathe?I modified a Rathburn ring stretcher a few years ago and
it kind of works but its not accurate enough for my liking.I can get
it to run true with a bit of mucking around but if I remove it from
the lathe and try and re centre it it takes forever.I figure there
must be a better tool that is more precise.I use a small lathe with
only 150mm between centres so I can’t use my ring mandrels.Any
suggestions? Thanks, Colin.
