Can you turn a bench grinder into a polisher and if so what do you need to do ???????????

Yes shove a pigtail on the end and make a buffer that will burn through steel if it ain't slowed down.

It's a motor that spins, so there will be a way of doing it!

Axminster used to do Pigtail adapters to fit a couple of different shaft sizes, but I can't find them now. I picked up a double shaft motor for free, and just bolted these on to make a buffer.

There are many shaped mops about that will go in a Jacobs chuck if you can adapt one to fit.

Walter has a motor bolted to his lathe to runs a Jacobs chuck, so he may be able to tell you more!

Neil is right Geordie

I have a motor with a 5/8 shaft. It is fitted with an adaptor (easily made by anyone with a metalworking lathe) that fits a threaded Jacobs chuck. A standard pigtail is mounted in the chuck to take the buffing wheels.

I will post a photograph when I get a chance.

Brian is also right you could just mount the buffing wheels on the lathe which has the advantage of variable speed. OK for pens, I found that the lathe bed got in the way though for any larger pieces.

I made a mini variable speed buffer sits on my pressing table from a lab stirrer in a previous life invaluable to me and in answer to your post there are right and left hand threaded attachments that fit the shaft of a grinder that taper the other end and sort nof screw a polishing mop on easily that can be changed quickly.

From my school days in the 1951 I finished school in the metal work room we all made a copper ashtray since everyone was exposed to a smoker or like me was a smoker. BEWARE there is no more deadly weapon than a flying dish of metal that magically turns into a UFO. If its your:fingers: pen you want to buff make it captive on a rod they are hard to find in the sawdust and like any buffing method it requires skill the speed is immaterial it is the application to the buff that counts, bit like the racing driver you get used to it but have to respect it.
