Best thing to do to your blasting cabinet.

I need to take and post some pics of my buddies new blasting cabinet set-up, pretty damn nice and he has the vacuum plumbed to the outside of the building with a big vacuum motor inline using big PCV pipe. Yeah the seams is a bit leaky too but a simply fix. Its one with the hopper under it and he bench mounted it instead of using the cheap legs/stand it came with so it doesnt take up any additional floor space.
