I had been connecting my shop vac to the blast cabinet when blasting, but when using glass beads it would suck all the beads along with the dust into the vac. I'm too cheap to buy a quality dust collector especially after seeing the home made ones in action. I got this lid at Amazon, it fits a 5gal bucket and an additional 2.5" shopvac hose with adapters at Lowes. My shop vac has 2.5" hoses to I figured it would be easy to plug it all together and collect dust instead of beads. Well, the lid orifice is too small to fit the 2.5" shop vac hose, so I dug out my heat gun, softened up the bung and slipped in the shop vac hose. Unfortunately it still didn't work correctly. All the cyclonic dust catchers that I have seen had an extension inside to force the suction to come from the bottom of the container and this one didn't have anything like that, so I epoxied a 2.5" length of PVC so that it sits about 2" from the bottom of the bucket. It now works great! it will still suck up the glass beads, but they all seem to drop out of the air stream instead of getting sucked into the shop vac bag. The dust, being lighter seems to continue on to the bag.
