Bought one used a while ago but I am not sure about the speed the blades are
turning. Is there an Ideal speed? or motor speed and pulley sizes that
someone can help me with?
Right now it is running with a 1750rpm 3/4 horse motor on it, with about a
7" diameter pulley on the motor.
Any help greatly appreciated.
You need more info. What size it the pulley on the cutter head. Multiply
the motor rpm times the pulley circumference on the cutter head and divide
by the pulley circumference on the motor. Multiply that number times the
number of knives the cutter head has. That will give you cuts per minute.
I think what you have is either correct or very close assuming that
the pulley on the spindle is about 2 1/2".
We recently bought an old rockwell/milwaukee 6" joiner that still had
the original motor and stand and I believe it's all original. With
the 1750 motor the pulley sizes are 7" on the motor and 2 1/2" on the
I'm sure you can find on the web (or someone here will tell you) what
that equates to as far as spindle speed.
