I am looking into converting my mini-lathe to cnc since my motor this last weekend burned up. Might as well do the change over.

My problem is where to purchase the required parts to do this conversion.

First off, I need to get my lathe working again so I can turn some parts I need.
I have an old treadmill motor that I want to adapt to this mini-lathe, Homier 7x12.

The treadmill motor has a flywheel that has a cooling fan attach which I want to keep, so I need a pulley that I can use to drive a idler pulley system for the lathe drive system. I'm not sure what the proper name of this type of pulley, J-Belt, Poly-V or Micro-V. It looks like a serpentine type belt. Any ideas where to purchase one of these?

Next part is the other end of the idler shart that drives the spindle. The original had a cog(?) type plastic pulley, I would like to have a metal one of this type. The belt is marked as 1.5x70, I need a longer belt than the original.

Where do I shop for these types of pullies?

Thanks
Jeff

Many TM motors had Poly Vee pulleys and belts.
Ideally you do not require the flywheel and it will impair the ability to control the spindle in a fast manner.
If there is a fan attached to the flywheel it would be better to put one on separately and remove the flywheel, you can then go with standard timing belt which are available from almost any local bearing dealer.
