The "sand" I have is not silica sand, but some sort of a proper sand
blasting media. It is of fine composition and does feel like powder to
the touch, like you said.

If it feels like a powder..its designed to be a polishing media and
NOT for rust or burr removal. You can..over time..remove rust with
it..but it takes a long time and it uses up media like a brush fire.

OK, thanks. Yes, it feels like extremely fine sand, the grains are so
tiny.

You never did indicate what your cabinet is to be used for.

General rust and paint removal only.

I have a Trico Mod 36 here at the house

Very nice, I have a 24" Trinco cabinet, that I will be soon selling
due to putting the big one in service.

And for rust removal..use Black Beauty media

OK, what size?

For polishing and smoothing I use both ground glass and glass beads

I wound up with (15) 5 gallon buckets of unused glass media, and ,
have given at least 8 away to friends.

I find little difference in my sort of work to crushed glass and bead
glass. Shrug

I also have a smaller table top version but the window seals are shot
and a "tank" type sand blaster from Harbor Freight that I use strictly
with playground sand to do bigger things such as boat trailers and
motorcycle frames etc etc

I hope that you use proper breathing equipment!

I've recently discovered a wet sandblaster mod for a pressure washer
on eBay for $95. It's very, very interesting.

It looks a helluva lot faster than the cheapie handheld blaster I have
or the bigger cabinet I once used at Gunner's.
