Position of the belt in the minilathe

[Robert1998]

Hi everyone.


Today, using the lathe I thought came to my mind. It has a belt that connect the motor with the spindle and you can choose to positions A, less revs but higher torque and B, the opposite.

I have it always in A, because I don´t usually need more than 800 rpm. but I have realized that if I don´t need that torque (I work with soft materials), the motor is running at higher rpm that I don´t need.

So, what position is better if you aren´t parting and working with plastics, aluminum and brass? Or it is a silly question and it really doesn´t matter.

Thank you

Best regards

Smaller diameter stock has a slower surface speed so faster spindle speeds required

Reverse for large diameter

I wouldn't run too high a speed with plastics to prevent them overheating and melting. Personally I find 1200rpm is fine for a top speed for everthing I do, including the occasional use of 3mm brass.

I'd stick with position A and enjoy the extra torque.

Thanks for your answers.

Is a brushless motor.
