Cut and Polish the Edge of Window Sills in Kolmården Marble

[pjop]

How do I do it?

Thinking about taking a diamond blade for the angle grinder for the cut and then trying to find paper for the regular oscillating sander.

Could that work?

Works perfectly fine!

I did so a couple of years ago. Sanded with regular sandpaper for wood and it turned out good, not perfect, but good. I didn't get that final glossy finish, but it might be possible if you use finer paper or polish.
