Re: Dust collector for Sandblaster?
Be mindful of the shopvac route. The filters in most shopvacs are not made to pull particles out of the air down to the size of the stuff circulating in most blast cabinets (micron rating). Those small particles are then shot out into the open shop air around you where you breath them in. Light duty is one thing, but when you're settling in for a day of blasting and using a shop vac, you'll end up doing a week of hocking up black phlegm.
Tie a white t-shirt over the exhaust port of your shop vac and have at it for a small normal blasting session. Then look at the shirt after and see what you're breathing.
