I built a dust collector out of two kitty litter buckets. Bolted a shop vac filter into the top one and cut a hole in the side for a two inch shop vac hose to plug into. I use a Harbor Freight dust collector motor to draw dust into the collector. I can't find my pics of the set-up. I'll get new ones when I have the cabinet out.
Everything breaks down and stores inside the blast cabinet when I'm not using it.
And the cabinet is on casters so it is easy to roll around.
