KMG and motors...

[AmericanPinto]

Hello to all from Pinto. Im from New Mexico and just getting started at knife making. I am currently redoing my small shop to set up for all the tools I will be using. I am looking at purchasing the KMG grinder possibly monday; however, I am on the fence as what to do about motor selection. My budget will allow me to choose the 1.5 hp with the step down pulleys from KMG but....I do have a 1.5hp motor I inherited from my father. The only thing is...the motor is 3450 RPM motor. I am wondering if that is to fast even if I buy step down pulleys. I see KMG's motor is 1725 RPM and the step down pulleys would slow it down even more. I am assuming a 3450 RPm motor might not slow down enough?

You can just use a smaller drive wheel.

4" if you are buying from KMG


3" if you have a choice.

I would think that from McMaster or MSC you could buy a pair of step pulleys to get the speeds where you want them.

Smaller drive wheels, and larger driven wheels than standard.

I know you can even Google a calculator to figure out what diameters you need.
