MicroMesh Swab Reference

(This page revised June 22, 2012)

MicroMesh swabs are remarkably useful for shaping and polishing concave rounded surfaces. Among other tasks, I use them frequently to smooth the insides of piston-filler barrels that have been roughened by friction from a deteriorating piston seal.

But it’s too easy to lose the card that comes packaged with the swab set, and you can’t tell the players without a score card — so this page lists the 12 swab colors in order from coarsest (Sea Green) to finest (Gray) along with their corresponding grit references in other standard systems. In the U.S.A., for example, ordinary sandpaper is graded by ANSI/CAM grit size, so the Bronze MicroMesh swab is equivalent to 400-grit sandpaper.

Colors in this table have been matched to real swabs on a calibrated monitor; if your monitor is off calibration, colors may be a little different for you.
