Thanks, my questions were private in relation to my specific account- not an issue with their product.

I just restarted maintenance after being off it for a few years--it was a pain to do that. After giving them my money, I tried to contact them a few times with some questions, but they don't return...

Thanks the information guys. Sorry I didn’t explain myself well. I got the bearings off the spindle with no problem. The inner races are part of the bearings. The outer race is the problem. There is...

Thanks. I am quite well educated but I cannot spell or write well for that matter...lol:)

Well,

I measured the shaft and could not detect a problem. When it was on the lathe it was measuring 0.015" run out at the same spot each time both at the flange face and on the threaded nose in...

I removed my lathe spindle to replace my tappered roller bearings. What is the best/safest way to remove the races? There is not a lot of room behind the race and you can't get a punch on them from...

I was checking the run out on my Chinese belt drive cz300 lathe. I had 0.0005” on the tapper and 0.0015” on the nose and on the flange face of the threaded spindle. I pulled the spindle and noticed...

Thanks again, great links and information. I am looking at this as an educational experience not just a CNC build.

Thanks, more good info for thought. I don’t think I can afford servos at this time. I guess if I went with larger steppers, not much more money, I should be able to run a belt drive—have to look at...

Thanks

Yeah, I know there are lots of different variables to consider. I actually have an mech engineering background. I have some books I can dust off to figure it out and get a ball park figure.

Thanks for the info and the video. Once I gather all the information I can, good and bad, I will set down and hammer out some calculations and then make a decision on screws and motors. I would like...

I will be happy with slow as well—it is a cheap machine toy after all. My guess is the faster you go the more inaccurate these machines are—just my guess…

Yeah, I worry about buying ebay drivers....

Thanks guys, great advice. Yeah, I will be in the take apart and put back together camp. Hardest part will be convincing my wife:cheers:

I am trying to save on cost and plan on going with stepper...

Thanks for the quick reply. My table is about 31" and I think the y screw is about 40" overall. The X axis screw is 20"overall and free floats on one end. I want to use the old bearing mounts on the...

I own a Wholesale Tools ZX45 RF clone. I am looking into CNC’ing the machine. I am just starting to look into this, so I appreciate the advice. I have a number of questions that I have not been able...
