Buffing motor rewire?
Hi all,
I just bough a buffer to polish some aluminum pieces I'm making (obligatory metal content), and I'd like to mount it upside down. In order to do this and be able to get to the on/off switch, I need to wire it so that it runs "backwards" or in the opposite direction from how it runs now. In pulling the base plate off, a large cap is evident. I know embarrassingly little about electrical stuff and I'm wondering how to rewire the buffer. Can I flop the power leads to the switch (the cap and the motor connect to the other side of the switch) so that both the motor and the cap have reverse polarity, or do I need to reverse the polarity only to the motor and not to the cap? Or? Thanks muchly, Peter |

You may find that the arbor nuts unscrew themselves if you succeed in this. Just relocate the switch... |

Don't change the rotation of the motor. Just wire an outlet with a
switch and use that switch to turn it on and off. Original switch always on. Dan |

I was going to use double nuts to prevent this. You may be right though. What about the buffers themselves? Those spindles are long tapered screws to grip the buffers, and running it in reverse will unscrew them. (And I think that both screw onto the motor shafts, one side of which is left-hand thread, so you can't even interchange them.

If they are affixed to the floor they are not always in the right place. If they are legal with a toe cover it can be an adventure to get your toe in the damn thing. just my $.02 rant lg no neat sig line |
