Pat.....I couldn't justify the cost of an admittedly far superior blast cabinet from TP or Eastwood. People who advised me all gave different reports about these things. Made the whole procedure far too complicated. A friend had gotten one from Harbor Freight, so I went over to his place with some parts and used it. He pointed out all its faults and what he had done to correct them. He was satisfied with his. I am satisfied now with mine, although I have done some "re-engineerig". All the high priced units have one-piece cabinets, which are sturdier and more leakproof. Mine is in two pieces, with a fairly chintzy rubber sealing arrangement. I replaced that with auto weather stripping, sealed with silicone, a very thin coat. Then I tightened the bejeebers out of the bolts, and, in conjunction with an old shop vac and some scotchbrite filters, have contained the leakage and dust. I fugure I saved a couple thousand dollars in the process. If I were using a blast cabinet all the time for heavy duty use, I would definitely opt for the units from TP, Eastwood and the like, and pay the money required to own one. The secret to successful blasting, as has been pointed out already, is the largest compressor you can get. I have a 40 cfm Quincy and it does a fabulous job. Pressure is not the issue, volume is the big factor. I run 120 psi and have lots of volume. If you have a small compressor, and pressure drops to less than 80 psi, it takes eons to do a simple job and people become discouraged. Hope this helps. All the best..... ..Greg
