I don't think I've seen a tutorial per se, but I'd take any leftovers and try
wet sanding before doing it on a nice blank. It should be OK, but it depends
on how it was stabilized, what it was stabilized with, how complete the
saturation is etc. etc. I'd rather test it on some leftover material before
committing a good blank.
I'd rather wet sand any plastics, because they seem to come out better
for me. And besides, the micromesh is less likely to 'burn' when wet
sanding.
(the following is very basic in case new people are reading. I'm not talking
down to anyone, just seems like a good question that others might be
wondering about also)
As for how to wet sand.. I keep a small bucket of water beside the lathe
and a terrycloth towel on the ways. I leave the micromesh on the water,
taking it out when I need to wash them with a bit of dish soap and a
fingernail brush. Micromesh or sandpaper, I do both the same way. I wet
the material and apply it to the spinning blank. You'll build up a slurry of
sanding dust that you'll want to clear away by dunking in the water.
Keeping the sanding medium clean allows you to see which areas are worn
so you can move to a cleaner area.
Some like to wet sand with some sort of support block under the paper,
(sanding block, felt block, wood block etc.) to get a more even sanding
and straighter lines.
Some prefer to use their fingers only. That allows you to feel for
overheating and also feel the wood texture and any ridges under your
fingertips.
The choice is yours, obviously. Try each one and see what seems right
for you.
