Does anyone know exactly what gear module the head stock gears are on the mini mill and mini lathe? I don`t have a disassmbled set here to measure just yet, but will soon. I found that the change gears seem to be module 1, 20 PA.
 
I've got a HF 44991 on my bench in pieces right now, due to shattered spindle gears. I'll be reassembling it tonight and/or tomorrow with the LMS steel gear set. I'm not sure what a gear module is, but assuming these are measurements that can be taken with calipers, I'd be happy to measure whatever.
 
Thanks. I eventually found that they are module 2.25 with a 20 degree pressure angle. Change gears are module 1.0 and pinion/drive gears on the mini mill are module 1.5.
 
Gear module ?
Brand of machine ?

This forum is for the harbor freight style mini mill and mini lathe. Sold by many others under various brands and configurations but generally all having the same headstock/gear configuration.
