Angle grinders are a bit fast, it needs to be variable speed, but yes it's simply an M14 profiling tool that attaches to a hand held machine.

The machine pictured is a Makita PW5000c with a speed range of 2000-4000rpm and a full water feed. You'd need that kind of equipment to produce the quality of finish in the images above.

You think that Makita with that RPM range of 2000-4000 would be OK with Carrara marble? Or too fast?

See you haven't improved your looks!

That should be fine for Carrara, most polishing is done in the 3000 to 4000 rpm range with diamond pads at 100mm.

Cheers. I had it in my head that 2000 was as fast as you should go with soft marbles..

Im just considering a few options regarding a wet polishr and this one does get some good reviews.

The fixed speed wet polishers available tend to be fixed at around 3700rpm.

With Carrara you'd be better off with silicon carbide discs though, there's no upside to using diamond pads wet unless you're doing huge quantity or dust is an issue.

Interesting.

And do you think dry polishing can produce as good a polished bullnose finish as wet?

The reason I am posting these porcelain pictures in here is because I tend to treat the porcelain as stone using 1/16'' narrow grout joints, custom made shower shelf, bull-nosing etc View attachment 81504

By the way that is some mighty impressive work, tops marks!!!

Out of curiosity, how long did that take you? What piece is on the end of your machine?

Thank you!
It took me about 8 weeks to get that bathroom done, solo work, all custom made, water polished, joist reinforcement was done, waterproofing, plaster was taken off the walls as I do not tile on top of it, windowsill was replaced and redesigned/bull-nosed, shower shelf, toilet box with custom made access panel as seen in pictures. Time consuming I can tell you that. It is a ''Diamond'' router 3/8''

How long does the router last or how many meters does it do,
