Hello folks. Here is a quick how to on making a cheap, compact, portable and did I say cheap, media blaster box/cabinet.
With a bit of scrounging, I spent about $35.00 making the box. Two "Sterilite" storage tubs and a media blaster gun. I scrounged the plexiglass, bits of wood, bolts etc.
The first pic is the bottom tub with the arm holes cut out. The tub measures approx: 29x17 x 18 deep (35 gal)($8.00 Walmart). The holes are 4.5 inches dia. There is also a smaller hole cut into the right side for the air line access. I cut these holes with a dremel type tool.
Next is the inside of the tub. I installed two sloped sides to aid in concentrating the media to the center where the feed pipe will be.
Here is the media blaster gun and pickup tube installed.
I made a tray out of the lid that came with the tub. I just cut it down to size, drilled holes with a half inch paddle bit, and laid it in place.
I installed some long sleeves that I cut from an old shirt. The Harbor Freight work gloves are $2.00 specials. The gloves have a wide cuff and fit snug inside the sleeves.
The top is also a "Sterilite" storage tub purchased from Walmart for about $7.00. It is the same width and length as the bottom but 12 inches deep and clear to let in as much light as possible. I installed a plexiglass window made from scrap 1/8 plexi. I taped the edges of the plexi with regular duct tape which serves as a gasket. The bolts were scrounged from my "misc" parts bins. The top is held in place with the bungee's.
A view of a GL1000 header about to be blasted. The media is Garnette simply because it was available. It tends to be a bit dusty so I will be looking for alternatives. A dust venting system would help.
I plan to add some weather stripping to the joints where the two tubs meet which will seal the joint more effectively. I set the whole thing on a bench when in use and then back in the corner when not in use. Again, simple, cheap but effective. Hope this was helpful to someone.
