Dave,
You mentioned about replacing the screws. Ball screws my friend ,and start looking ,since the small ones are hard to come by and they are not cheap if bought new. You may also want to check out Phils screen for the lathe. Guess you'll be threading in a short time.
Let me know how it all works.

I bet he did but also bet he doesnt use it for fear of being sued ;D
Bit curious, what spindle speeds do these wee lathes have?

Hood

Hood, the original 3/4-16 thread headstock is only recommended at 7000RPM but I've since gotten the ER16 headstock that is "supposedly" good to 12,000 RPM. My aftermarket treadmill motor does 10,000 RPM with no issue, so that should give you an idea of where I'm at.

Here's the website for the original setup: http://www.taigtools.com/mlathe.html

Rich, after looking around, this lathe would just be too much "underkill" for ballscrews as delrin "adjustable" nuts work just fine. I thought they would wear so much more than they have but have been just unbelieveable in their performance on this thing.

Thanks for looking,
Dave

Hi Dave,

Are you using a Delrin nut on the cross slide as well? If so did you just copy the original bronze one?

Cheers,

Peter.

Hi Peter,

Yes, but I took it a step further as I've actually screwed the "boss" of the nut, to the crosslide from above (drilled and counterbored through the top of the crosslide. Sorry, no pics of that, but will try to remember to get some in the future.


Thanks,
Dave

Thank you Mikee, perhaps you could start a thread showing off your pool cue lathe or your wood router?

Everyone here loves to see what others are building.

 well Dave it has been a good day
 i got my cnc to cut a circle little flat on the sides  i have a little play here and there i will tighten it up  hope fully that will make my circle a little more round   .
  need to get my  cnc where it can repeat
 i will start getting some pictures  together  you are going to have to help me post my pics i don't know how to on this site
 (my stuff  back yard cnc ) but i  have very much enjoyed this
i sure didn't know what i would have done without some of the guys in here helping me
 taig has a lathe chuck with a large spindle bore out now with a indexer  on it  that's the one i would like to make my 4 axis with  in truth my tail shaft on my taig lathe  it is so loose
  I'm very interested on how you got your lathe in tolerance

Hadn't seen that on the site, got a link, and/or a price?
