Blast cabinets need not be hard. I made a very serviceable cabinet out a mediumlarge cardboard box, half a roll of duct tape, a 2 foot square piece of scrapglass and a fifteen dollar blast gun from Harbor Freight 7 years ago.Still using it. Just be sure your air compressor will put out sufficient volumneand don,t cheap out on the blast media. Glass beads work best.Jeff WilsonN899WTSt. Louis'Flyin Low and Slow'________________________________________________________________________________Date: Thu, 8 Jul 2010 12:51:48 -0400 (EDT)

Now, see... Harvey's setup addresses the wide wing gaps at the flop by incorporatingwing gap seal strips on the flop itself. Very nice solution.--------Oscar ZunigaSan Antonio, TXAir Camper NX41CCRead this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Thu, 8 Jul 2010 14:15:03 -0700 (PDT)

JimI have built 3 different blast cabinets based loosely on the Chris Bobkadesign paper on my web page. You can see the first two here.http://westcoastpiet.com/chris_tracy.htmThe third one is my best design yet. See attached pictures I have very little room for things in the garage so I built my blaster tohang on the wall next to the powder coating oven. To save space below itfor the band saw, I elected to push the media back into a supply wellhanging off the bottom. It is made out of 3/8th inch plywood I had lyingaround. The plywood on the back does show some wear. I think if this onewears out, I will build one out of metal, but I will probably just glue apiece of metal on the back and it will last for ever. I am surprised howmuch I use it and cant imagine welding without one.I used safety glass on the first box but it frosted over and was expensiveto replace. Since my second box I have used Plexiglas. I have been usingthe same piece of Plexiglas for 3 years and you can see in the picture it isstill very clear. The trick is to cover it with clear plastic wrap used tocover food. Replace the plastic when it frosts over. With my setup as longas I don't blast directly at the plastic it will last a long long time. Imade it easy to remove the Plexiglas so I can replace the plastic wrap.The homemade light sits on top of the box on the outside It has anotherPlexiglas window the full length of the cabinet but this one is protected bya piece of plastic used for florescent ceiling lights. This is the bestlighted blast cabinet I have ever used. I run a 20 gallon 5 hp 100% duty cycle compressor set to 80 psi. I havetrouble with water developing in my air supply when I use it hard. I likedthe Campbell Hosfeld gun I wore out much better then the gun I have now.I can't imagine it cost me over $50 to build. ChrisSacramento, CaWestcoastpiet.com-----Original Message-----
