Re: cnc lathe/mill

Man I see what you mean Edmund, on ebay a 1950's MLV lathe is 6k, but
that is way out of my price range. I am looking for a reliable, easy
to use lathe/mill close the size I listed in the previous post for
around $1200 or less. So I am open to all suggestions. Thanks

ebay HLVs and second operations, I have thought the second op lathe
would be a good one for a retrofit, and if your lucky enough to get a
good one it will last you a lifetime, (Rolls Royce of small lathes in
my opinion),..... as for round columm versus a dovetail, my preference
would be dovetail, very frustrating if for some reason you have to
raise a round columm, and dial in again,
