Thread: converting a grinding machine to polish machine?

Just to add that 2" / 50mm wheels on a high speed grinder will reduce a lot of the overheating risk but still be careful not to linger a long time in one spot.

The smaller the wheel the slower the speed. Castwellplating.com has a good tutorial and wheel speed chart. They also sell spindle extensions.

Yes I heard about this the left and right sides may be differents.

Well I found an old grinding machine for 350W, costs me 15€. I think I will think later about spindles and i will take some cloth wheels to put to each side of the machine and I will see how its gonna work. The spindles I found are about 12mm ( may I'm wrong about because some says inch so I need to check it up and i can not on my phone) for 20bucks for two of them. But only the spindles and no other pieces.

Today I make call to professionals' store even they have no any polish machine but just grinders with stones. It's not just me who think this is bizarre?

You need to buff on the lower half of the front of the wheels which is why extensions are necessary. Its easy for access on the top half but if it goes wrong you will have a razor implanted somewhere in your chest or belly. Buffing on the bottom if it goes wrong the razor is carried away from you. The 1/2 inch spindles are basically the same as 12.7 mm if held by grub screws but obviously different if threaded. I searched for a buffer but found only tjose dealing directly with them offered them and they were the premium machines with prices to match.

The guys are right about the extensions I'm sure but I have 3 machines ( grinders) set up for polishing ( yes I do a lot of razors) and each one I just took the guards off, slapped on some cloth and off I go.
Granted I have 30 yrs behind me but this is the way I've always done it. I even manage to polish Tabernacles and
The book stand here this way as part of my "regular" work. I've done 3 of these over the past 2 months.
This makes polishing a blade easy by comparison.
