Home made sandblast cabinets..lets see them
Well I gave my blast cabinet a whirl and as far as the cabinet goes it works great,however my sandblaster is not that great either my blast media is insufficient "red oxide" or my siphon fed blaster sucks or both! I tried removing that wrinkle black finish on some cast aluminum valve covers with poor results. I had better luck blasting rust off of a proportioning valve.
Here is what I did to make the cabinet:
cut two 4" holes for arm openings and used 4" galvanized pipe tabbed onto some flat metal and secured with screws. (note) a 4 1/2" or 5" opening would be better but 4" was all I had. two hose clamps hold the gloves onto galv pipe stubs. Silicone around any openings.
The square view port was something I fabbed up myself out of some 2"X6" 26. gauge galvanized angle I had, but you could screw/seal the plexi-glass right to the barrel.
My shop vac hose fits one of the threaded barrel openings perfectly just shove it in. Air and media hoses go in other threaded opening just drill plug out to proper size and thread it in.
Some old propane gas grill grates or metal shelving inside barrel makes a nice removable work surface.
The base frame is uni-strut with 3/8 rod sleeved with conduit and the barrel is held in place with some sheet metal hanger stock.
The door was made of plexi glass, plywood would work just as well weatherstrip the outer edges. Cut a vent in door it to allow air in as the shop vac sucks air out. (sandwich some filter media between the door and vent to help keep media in cabinet). A simple nut and bolt will hold the door shut
I used a bathroom sink drain at bottom of barrel to sweep media into a bucket for reuse. If you would want to have media automatically recycle a large funnel shaped hopper would need to be cut in bottom. What I did is good enough for my needs.
Lowes had the 3 hockey puck style under cabinet mount lights for $20 bucks. Need 2 1/8" hole saw for these.
Harbor freight had the gloves for around $5.00 they are ok but longer gloves would be an improvement.
I know you can buy cabinets cheap enough but this cost me hardly anything and I have the satisfaction of making it myself.
