1) Motor to countershaft belt (about 10mm wide). The best belt for this is the NuT-Link Type with metal pins. Link belts help to reduce the vibration usually passed from a single-phase motor to the lathe
2) Countershaft to Headstock spindle belt (about 13 mm wide) For the ML7, the T-link type is too stiff and using the a "Power Twist" type is recommended. 
3) Select your required belt - but, if you would like both, they need to be ordered individually, i.e. complete one payment, then go back to this page and make the other.
