Tech Help!! Any one converted a grinder to a polisher??

I'm just wondering if anyone has converted a grinder to a polisher, I'd really like to have a polisher and I have a unused grinder at this point.

Any help is appreciated.... thanks fellas!!

 

Arent they different rpm's?

 

Chad, I bought a buffing wheel and put it on my 5" grinder. Works great for small pieces. Now I have a wire wheel on one side and a polishing wheel on the other...works great so far.

It does run slower than my Balfor unit but still does a good job

 

Bench grinder, angle grinder, what have you got? I have a cheap chinese bench grinder (X-mas present) that is set up for buffing. Course rouge on one side and fine on the other. I have a second set of buffing wheels for plastic. About $15 for a buffing wheel.

 

It's just an old bench grinder... I didn't know if I needed a ext. shaft or faster rpms or what?

 

You mean like this? I can't speak to how you're supposed to do it, but I just swapped the stones for some buffs and hold em on with oversize washers.

May not be "right" but has polished a lot of stuff.

Oh yeah, that's a $15 swap meet chineese pedestal. Filled the tube halfway with wheel weights then welded all 3 pieces together. Again more "you can't do that" with welding steel tubing to cast iron, but it works. It's hands-down the nicest portable grinder pedestal I've ever used, good m*** center and vibration damping. Great for moving the buffing compound mess into the backyard.

good luck

 

That's pretty much what I'm looking for shifty!! did you put those extensions on the shafts or what? looks like a tubing with some set screws?

 

Those extensions were on that motor when I got it. I've seen them sold alongside grinding stones, I think they're to allow stones or pulleys to be mounted to plain electric motor shafts. That's what my buffer is, a 1960s electric motor, same as you'd find on an air compressor, etc.

 

Thanks Shifty!! I think I'm going to try and make mine into a buffer similar to yours....

 

Chad, what shifty posted looks a lot like mine too, seems to work fine.

 

Cool! Works for me... thanks GV

 

Never to a polisher but I converted a thumb and back of a right hand into a m*** of red meat pulp when the 12 " wire wheel grabbed my ****ing latex glove and drug it in.

Also don't ever use Final Wash/ Prepsol to try to clean up the mess, never, ever, ever.

 

Yes- I've used my Craftsman bench grinder as a buffer/polisher quite a bit.

Sorry to bring this back up, but what about an angle grinder? I have a buffing wheel with the metal insert and want to use it on my angle grinder. I tried a felt wheel on it already and it looked like christmas- that thing disintrigated in about a half a second. It was completely gone before I could turn the damn thing off. I am still picking that **** out of my beard. Will the one with the metal center work? I wanted to polish some trim with it. Will it be too course for trim?

 

caswellplating.com has the shaft Adapters for about $10.00 for the bench grinders.
