tripping breaker

[dregs2193]

My shopsmith was running fine, i adjusted speed and it began tripping breaker. I removed power head, took off belt and motor does not trip breaker on it's own. Any thoughts???

I would hope that the Shopsmith is being powered by a dedicated circuit (nothing other than the Shopsmith).

I would start by lubricating the sheaves, reinstalling the motor and retension the motor drive belt. That done - check for motor startup again.

While powered down, blow all the sawdust out of the motor housing and motor pan.

Been running it on same circuit since i bought it 2 years ago. never had problem until i adjusted speed dial..

When you try to run it without th belt and listen carefully for a click on start up and run down with the belt off. The click is more apparent on shut down.
This will verify that the centrifugal switch is working. One thing that can happen is the V belt can jam in the sheave if the sheave is bound up due to lack of lubrication. This causes extra strain on the motor. Lubricate the sheaves ( don't be afraid you can't overlube ). If this does not work come back and ask more questions.

Check out this guy who rebuilds them, better and stronger. I don't know of anyone who did not love the results.

it was easier then i thought...

[dregs2193]

oh sweet... thats what failed. guessing that is common..

[everettdavis]

It is more common when someone frequently tries to turn it when shafts are not spinning. It puts stress on the quadrant, and frequently bends it if the teeth don't break off on the control dial.
