Here's my setup:
First of all, I build a make-shift sandblast booth in a corner of my shop, out of 2x2 lumber and plastic sheeting. The booth is up against the back door of my shop, so I can open the door to get some air circulation going when I'm working in there. You can see there's a squirrel-cage fan blowing in at the front at ground level into the booth, and out the door. There's also an upright floorstand fan along the right side, blowing in through a hole in the plastic. When I finish off a tank of sand in the sandblaster and am ready to start sweeping up, I turn off the squirrel-cage fan but leave the upright fan on for air circulation. You can also see the air compressor just to the left of the booth, with another squirrel-cage fan on the workbench blowing up onto the compressor pump and motor, just for a little additional cooling....and it does work pretty well.

This next picture shows the basic interior of the booth. I have two 55-gallon drums....one for a worktable and the other is my sand-sifter.

....and here's a closeup of the sand-sifter. All I did was take a 55-gallon drum and cut the top 1/3 off. I then cut out a section of the top leaving a lip around the edge to attach some attaching wire grid chicken-wire stuff. Obviously this is too coarse for sifting sand, but it'll hold up the finer door-screen material used for the actual sifting. I then just bent the top edges of the lower 2/3 of the drum in a little, to allow me to flip the top over on top of the bottom. I lay some window screeen down into the top part and drop my dirty sand into it, where it gets screened. The good sand drops down into the bottom, and then I can lift the top section off and dip out the cleaned sand.

Just curious how others did this, and thought maybe I'd pick up a tip or two, or at least share one with you.
