Topic tags/keywords: question tablesaw

Hi Folks:

I’m restoring an old Craftsman 113 table saw (yes … I know I can’t turn a pig into a racehorse … but I can make a fast pig!!)

I’m replacing the 1.5HP motor with a 3HP motor, and adding machined steel pulleys and a link belt. I’ve also made PALS-style adjuster brackets for the trunions, and am making an adjustment tool with a dial indicator.

My question is … what speed should I run the blade? The motor is 240 volts, 15 amps, and spins at 3450 RPM. I have several options for pulley sizes, and can pretty much spin the blade at any speed I choose.

What speed do you recommend?

Montana—I had a similar saw that ran at 3450 rpm from the factory, so I think that’s the right speed.

I agree with Don….factory speed of around 3450 is best.

The manual will probably have the rotational speed of the blade. I suspect it’ll be somewhere around 6000rpm.

Don’t get carried away with feed speed. The motor may be able to handle it but not the trunion. It was designed for a weaker motor and the bearings or even the cast iron may fail if used like a cabinet saw.

Pulleys on the 113 are 1:1 so its about 3450.

A word of advice, stick to whatever the manufacture recommended for blade speed. Bad things happen when you tinker. Just saying….

If you install the machined pulley’s from inline industries it bumps the blade speed up to 3833 rpm using a 3450 rpm motor. The motor pulley in the kit is 2 1/2” and the blade pulley is 2 1/4”. I guess you could install them the other way around and get 3105 rpm, but I don’t know why you would want to slow the blade down.

I have a 113 table saw with (I believe) original pulleys. The pulley on the arbor is slightly smaller than the pulley on the motor. Because of this the blade spins at a slightly higher speed than the motor.

Have your say...
