REQ: Mirac leadscrew details

[Mad Professor]

Hi All.

I have been reading over the user manuals for the mirac lathes, but I can't seem to find any details regarding the leadscrews.

Does anyone happen to know what leadscrews are used in the 1990 model?

Thanks for your time.

Best Regards.

It turns out my Mirac is using 5mm pitch ball-screws, with 12 tooth pulley on the stepper, and 30 tooth pulley on the ball-screw, (2.5:1 ratio).

Best Regards.
