Clueless wife

I need help!

My husband has an old Delta Milwaukee bench lathe from the 1940s. The probl em is that the motor is too fast for the turning he typically does. On the lowest setting, it's still faster than the highest one on his previous lath er (3200). I would like to surprise him with a new variable speed motor for this lathe, but I'm way out of my element and don't even know where to sta rt.

Any help would be great appreciated!

If the lathe has a speed adjustment capability now (likely stepped pulleys) it sounds like a change of the pulley on the motor, and perhaps the belt, is all that is needed to slow it down overall. For example, a smaller pulley on the motor would reduce the speed for each pulley on the top. Has you husband looked into this approach?

Does the lathe have a set up similar to the one pictured here, i.e., one pulley on the motor and a stepped pulley on top? If so this may solve the problem (inexpensively!).

The problem would be that a lathe variable speed motor can go two ways, the cheap way is a DC motor and a simple rheostat.

The more expensive way is a multi-phase motor and a control box for that.

The problem with the DC motor is the motor lacks power at any voltage but "full".

The other solution depends on getting the right motor and speed control

It almost might be easier to simply get a slower motor to replace the one he put in

As mentioned previously, changing the pulleys on the lathe may be all that is needed. That is a user operator error. However, if the pulleys still d o not allow the lathe to run slow enough, a new motor may solve the problem without affecting anything else on the lathe. Assume the current motor is a 3650 rpm motor now. By changing the motor to an 1800 rpm motor, you cut all the speeds in half no matter which pulleys you are using. Go over to Google and type in "1800 rpm motor" and you will see many motors show up in price from $80 on up. In various horsepower from 1/4 to 1.5 hp. Just get one the same hp as the current motor. Hopefully the shaft will be the sam e so the pulleys will slide on easy. And someone will have to know somethi ng about wiring to put a cord and/or switch on the motor.

Is there a back gear to slow it down ?

What is the speed on the motor - can a slower one be found ?
