I am working on building my motor mount for the cross slide for my lathe CNC conversion.

Documented here:

I cannot mount the motor for a direct drive, hence I need to mount it below the ballscrew and using pulleys and a belt to drive it. I sort of have it figured out how to do it, but I am wondering about building some sort of belt adjustment into the mount. Can anyone post some pictures on how you accomplished this?

AND....

I've been looking at pulleys and belts over at https://sdp-si.com/ to drive this thing. Good lord....what a selection! I guess my big question is: how do I figure out how long of a belt I need? I thought there was some sort of on-line configurator to make sure the right pulley and belt combination was ordered.

ANY help will be greatly appreciated.

Thanks

Mike
