Sure, this is an old thread, but I haven't seen much discussion about blast cabinets in quite awhile. My kid's boss bought an HF blast cabinet recently and he really likes it. He followed the tips in the reviews and sealed its seams well with silicone before he ever turned it on.
Yesterday I picked up this Nesco (made in USA!) cabinet. This cab has floated around my circle of friends for the past twenty years, at least. Its seams are welded, so there are fewer potential leak points. The gloves and window are in good shape but it needs a new hose or two, and I should probably add a dryer to my air line. It came w/two guns and a handful of tips in different sizes. The back has been extended so you can get larger items inside, but it won't take a minibike frame.
I bought a Campbell Hausfeld compressor at Montgomery Ward on 1994. It is rated 125 psi max, and should blow 5-6 cfm at 90 psi w/no problem. That sounds like enough for the small jobs that I'll be doing.
Has anyone else built or bought a blast cabinet recently?
