Jason, I have seen some Hardinge lathes sell for around $4000+ on 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,
Just my preference for what its worth,..............Edmund..................

Thanks for the info dave,
I really started to look up info, and like you said they are all the
same, but what suprised me was all the bad feedback on the 9x20
lathes. Another downturn is the need to change gears or belts for
diffrent speeds. At my school we have a enco lathe, with about 40"
between centers, but its pretty old, and has as alot of backlash and
runout. I needs alot of work to get back to good runnign condition for
precise machining, so I want my own lathe and I want to convert it to
cnc. Can anyone suggest a lathe of good quality and ease of use that
is around the size of 9x20 or bigger under 1200 bucks?
I am favoring towards the lathe, but am still thinking about the
possablilty of getting a mill and converting it to cnc. Just like the
lathes, all of them seem to be the exact same thing. Man no one can
come up with their own design. I plan on converting a mill to cnc too,
but like the lathe I am not sure what to go with. I did see a website
selling a rongfu31 mill converted to cnc, but for almost 8k, so I know
its a good canidate for a mill, but does anyone have any suggestions
what mill they would go with if converting to cnc around 1200 or
below? I know the lathemaster mill has a dovetail colum which is
better than a round colum, but since I am going to be putting the
stepper on the quill, I dont think it really matters.
I really am mainly looking for people to give me suggestions on what
they think is a good lathe or mill for converting to cnc around the
size and price I am looking for, as I don't know what type of stuff to
look for when shopping for one of these machines. Sorry for the long
length of these post of mine.
