I'm refurbishing a Lortone LS12 for a friend.

It was lacking the motor pulley & the blade pulley.
I ordered the blade pulley from Lortone. it's 4".
I didn't order the motor pulley because I haven't chosen which motor I'm using. I have various with different diameter shafts.

At our club shop we have the same saw with a 4" on the blade & a 2 1/4" on the motor.
That delivers 970 RPM from a 1725 RPM motor (if I did the math right).
Is that standard?

I know these saws have a rep for feeding faster than the blade can handle, so I don't want to run the blade too slow.
melhill1659, I know you've got this saw.

I bought mine from aDave and Tony. It’s great but moving to “fast” It Does Not 😂. I can take you pics if you need me to.
