Shopsmith Forums

Okay! So after I checked all the wires (connections were good) I flipped the motor in the mounts and looked inside the wiring compartment in the tail of the motor, I noticed that the contacts were about 1/8" away from each other, so I took a small screwdriver and bent the stationary side until the gap was about 1/32". gave it power and it fired up nice with no hum. I let it come to a stop and flipped the switch and it fired again perfectly. After doing it about 10 times, I called my humming motor fixed. Thanks guys! Now what have I done wrong????

I keep saying this... If your Shopsmith (or anything else) will not run, "always begin at the beginning. The motor capacitor is not the beginning". I have said it several times here and maybe I need to just post it weekly (or daily). Maybe someone will relocate the last thread on this where Bill Mayo discussed it well.

The beginning is at the plug... Is power getting that far? next the switch. Is power getting that far? Then is power getting to the motor terminals? Then is the centrifugal starter switch working. Notice that I have not even mentioned the capacitor yet... It comes in about here. Every time someone has any run problem several guys want to replace the capacitor first off. Sorry, it just does not work like that.
In this case since the motor hums when the switch is flipped we already know that the power is getting to the motor... Sorry, I don't buy this stuff about it being a poor connection, other than at the starter switch, if it will make the motor hum. It can have connections that need work but if it will hum that is not your immediate problem. Begin at the beginning... Follow a logical progression and fix any problems where you find them but avoid changing a bunch of stuff until you have diagnosed the real problem for sure or you can be led astray.

Do Not take Farmer's comments personally. He was attacking the 'problem' not any individual!:)

Also he IS 100% correct!;)

Mark-b: Nothing! You done real good!

And you should keep trying! We all here at this site try to do just that, including the farmer. As I read through his post, I did knot get the idea he was contradicting you (did knot even think along those lines until you responded), he just wanted to help like you did.

You do know that its "not" and not "knot" right......just trying to help.

If he was "knot" having fun it would all be for "naught".

You'd probably have to help a lot on the first and last sentence in this post.

Thats "cute".

Wow you people need to step back from the computer and use your shopsmith some more.....
