Mark,
You're right on target. And Donald has some great suggestions.
However, I made my shop vac the water trap. I usually keep an
old small shop vac around for the blast cabinet. (Watch yard sales
for used ones.) I must admitt that I have trashed the bearings
on the motors of a couple over the years, blasting.
Make sure that they have a deflector on the inlet port that is pointing
down, or is rotatable. (You can always make one out of some flashing
and pop rivet it to the vac.) Point the deflector down so the dust
will be deflected to the bottom of the vac. Put a couple of inches
of water on the bottom of the vac, and you have a water trap in
you vac. Less hoses, and pieces.
