I have a third hand SS from the late 50's. I've looked up it year but don't remember it right off hand. I have had it for a year now and just started to use it. I cleaned it all up and lubed it when I first got it but then didn't use it. I have cut a couple pieces with the table saw and began to use the joiner. I will lose rpm and bog down during both operations almost to a stop. The extension cord its plugged in to gets hot. Now while running the rpm with just change up and down. thank for any help

Get a bigger(wire size), shorter extension cord.

Shorter the better.

#14 is good.

#12 is better.

#10 is overkill unless very long.

A dedicated outlet is good.

thanks

OK will give it a try tonight and let you know if it is power drop from the extension cord. It is on a dedicated circuit for my tools and only thing plugged in at the time. I will get it rearranged so I can get it directly plugged in and get back to you.

If the motor is bogging down, the voltage is dropping! That is a forgone conclusion.

As recommended, I would deep six the extension cord and plug the Shopsmith into and outlet that you know is not being used by any other appliance (a dedicated circuit for the Shopsmith).

Then lubricate everything and try again.

Oil it here:

and here:

Then if you still have a bogging down, set the speed to saw range and just let the Shopsmith run awhile to loosen up the belts.

NOTE: You are using a sharp blade when doing the cutting and it is the correct blade (crosscut or rip), we all ASSUME that.

These are not my photo images. They were posted some time back by Nick.
