I got some ideas searching the internet for a way to do Soda Blasting with a home made rig. I got about 5 ft of 1/2" ID clear tubing, a blowgun, some duct tape, one of those clear Ozarka one gallon drinking water bottles, a large plastic soda bottle, something stiff to tape to the last foot of the tubing to hold it straight ,a stiff piece of single strand wire like romex about 10 inches long, a 2 rubber band tight fitting particle mask (3M, they usually have these at Home Depot in the paint department) , goggles that seal well and an air compressor. About duct tape, the only real duct tape youre going to find is at a real air conditioning supply company, the rest of them are just cheap imitations. When you use real duct tape it is HARD to get off. The only thing that comes close is the black 3M duct tape at Home Depot.

Cut a hole in the top of the big water bottle a little larger than the diameter of the soda bottle and then cut a hole in the bottom of the big water bottle that the top of the soda bottle will fit into then poke the soda bottle through and put the cap on as shown in the picture to connect the 2 bottles so they will not come apart. The inverted soda bottle will help feed Baking Soda to the end of the feed hose.

Drill a hole in the tubing about 6" from the end that is just a little smaller than your blowgun nozzle and stick it through it.

Tape the hose to the blowgun with the duct tape.

Tape the wire to the other end of the tube leaving it sticking out about 2 1/2" to keep it up in the soda, then tape the stiffener to that end of the tube to stiffen the last foot of the feed tube.

Stick your feed tube in the feed bottle, fill it with baking soda and have at it. You have to rock the bottle occasionally to shake soda to the bottom and once in a while the tube will get too much soda and you'll have to empty it but for the most part it worked pretty well for me.

You don't have to have a big compressor to make this work. This is the compressor I used and it worked fine.
