Sorry, that is very correct and could be a huge mistake. I was using 2000 for a completely unrelated project and it was on my mind. It's not rated for under water application

ha ha, I knew what you meant about the GE1200...

I was curious about that 2nd disc. Google found this for me:

I might have to try on a scrap, unless the glass store is reasonable and I don't want the hassle.

The first 2 discs are called flapper discs, they can be purchased at any welding supply / tool supply store. The discs are made up of overlapping pieces of sand paper. Never thought of using them but tried it out today in the shop. Works great.

Ya, I've used them before, (not on glass), but much coarser around 60grit. The one in the video is fairly fine and has some flex.

What grit did you try today and did it leave a fairly honed/polished surface condition?

Cheers and thanks for experimenting!

All I had was an 80 grit but it worked amazing to smooth out a bad cut that was made on the 116 gal that I am rebuilding. Going to pick up some 180 & 220 grit tomorrow.

They have other 'straight cut' diamond router bits, which can be used on a table with water and a parallel offset fence to put a true edge back onto the glass.
