I do quite a bit of Media blasting in a Barrel Blaster cabinet and have been using a home made dust collection system I found on the internet. Uses a 5 gal bucket, a couple inches of water and a shop vac. I works fair if at all. I've been through 2 shop vacs and finally decided to buy a commercial dust collector. The dust in my shop was bad. So I pulled the trigger tonight on a Eastwood 20027 dust collection system. I'll let you know how it works when I get it in service.
