Micromesh Grades

[qquake2k]

Does anyone know what the 6000, 8000, and 12000 Micromesh grades equate to in sandpaper grit? They're missing from all the charts I can find. I edited the chart to make it easier to read.

6000 = 4microns
8000=. 3microns
1200 presumably = around 1 micron

I imagine when you get as fine as a couple of microns there's not a lot of abrasives that can get that fine hence equivalent ratings for standard abrasive like aluminium oxide don't need to go that low.

I use a 3 micron paper it's designed to polish fibreoptics, there is little abrasive feel to the paper.

Never felt the need for micro mesh. I note Timberbits who does all the pens for a prestige gallery near me uses down to 400 only, always has, can,t fault his finishes.

I use Micromesh on acrylic, not wood. It makes a big difference on plastics.

Converting is difficult, MM 12000 is around P 4000 - 6000 I have heard. But I never met a P 6000 sheet so I cannot compare...

I am not sure to agree Peter, by the sight of this vid where David uses the whole set.

Of course, one can do without it for a satin finish, but to obtain a sword-like reflect MM is invaluable for most plastics and CA, imho.

Gratefull for this info Pierre I figure I go back to far. I have the immaculate early pen from David when he never used micro mesh. We swapped through the U BEaut pen swap when David had been turning only a few months. Because we swapped in person we established a friendship that is important to me. I never use MM and my finish on plastics is blemish free and brilliant gloss. I never liked the use of water anywhere near the lathe.

Earlier today I said I do learn more every day, thank you.

This list go to 8000, nothing for 12000.

Taking all of this to an extreme brown paper is ultra fine.
