I bought one of the pressure tank blasters from HF and built a cabinet with a hose sized hole that I can slide the hose through so I can use it with the cabinet or separate. Home Depot's cheapest bathroom fan works great to suck the dust out of the cabinet.
If you are trying to clean big parts, build yourself a tent out of plastic to contain the mess and pick up a surplus full face gas mask on eBay so you don't breath the dust. Be sure to clean the grit out of the shower so your Dad doesn't get mad.
