Garnet as blasting media?

[Doug in NJ]

Hello,

I was in Tractor Supply yesterday and I noticed that they had 80-grit Garnet media for only $25. How would garnet compare to glass beads in a blast cabinet? I have been using glass beads, but they are a bit wimpy for rusted stuff.

Thanks and Merry Christmas to all,

Doug

Quite OK for rusted parts.

Just test when you are doing external sheet metal for "profile" finish.

I looked it up, and according to this website's chart (link below), it may be a little better at rust removal then glass bead. It's harder then beads, but doesn't last as long.

My harbor freight benchtop cabinet wouldn't feed abrasive larger than glass bead,and I had to add a different gun,to help prevent clogging.

If you have the steel pickup tube that you dunk in the media, no wonder.

Modify the cabinet if you want any success.
