For those on the list that think it sure would be nice to have a blast
cabinet of any sort, but don't have space for even a small one, you can
do what I did when I lived in an apartment and make one out of a box and
a sheet of plexiglass. I used a box about 18x18x24 and taped three of
the flaps up, leaving a long one down for my arms. I taped a piece of
24x30 plexiglass to the top.
Bought a cheap sand blaster hoper/gun setup from Sears. Here is an option:

Used it out in the driveway with gloves and a respirator - too much dust
for in the garage. Given the ultra fine silica dust, a respirator is
important - you need more than a dust mask. Sifted the used play sand
with a mesh baseball cap to reuse.
Worked great for my TR6 suspension bits and folded up under an inch
thick. Didn't have a compressor, so ran it off partially empty scuba
tanks fed through a portable air tank.
Hopefully this some of the space or finance limited list members that
there are resourceful ways to do things like sandblasting.
