Re: Calculating Tablesaw blade speed
I have asked at a few places what the optimal rim speed of a blade is and have yet to get an answer. I suppose each blade has a different optimal rim speed.
In any case... You assumed the speed of the original motor to be 3600. That's possible but it's more likely 3450. The motor you're putting on runs at half the speed of the motor you took off so doubling the size of the original pulley will give you the same speed you had before. It will also cut your torque in half so in essence you end up with a 3/4 HP motor.
All of the above is very roughly speaking. There are far to many variables to give accurate numbers but in cases like this, getting close is usually good enough.
