I picked up a used 8 x 12 Central Machinery lathe.
Tag says 07 model ...
Guy i bought it from said he only made watch or clock parts or something ......
machine is not wore....
it's not scratched or dinged up it just look like it's been sitting in a basement for a long time paint looks like it's new.
Most of the tools are still in the plastic so fella didnt do much with the lil thing....
This is my first mini lathe...
I've been Machining for 20 years....
So the machining aspect is not my issue...
I've got the lathe setup on the table that I made and I'm now going over it with my ol trusty interapid test indicator.....
I put a dowel in the 3 jaw Chuck and I can get about .003 run out which I understand or am I'm hearing this is typical , normal or in tolerance...
I need it better !!!!
so I took the chuck apart today deburred ,cleaned it up, took a stone to it and just made it slick as could be.....
reinstalled and I'm still .oo3 out of round not to mention out about the same horizontal in 4inches or so toward chuck...
I guess the confusing part is when the chuck was off I put the test indicator on the adapter and swung it and I can't get a half thousandth of variance anywhere....
Bearings maybe ?
I've been reading post after post after post and videos on YouTube and all kinds of stuff on this lathe and I figured I would start my own post to get some insight I plan on doing quite a bit of threading with the lathe as soon as I can figure out how to engage the half nut and change the change gears I'm use to a big mazak I don't think I've ever changed, change gears before ?
Any input would be greatly appreciated
Thank you
