Highly Versatile Soda Blaster

This Instructable is going to show you how to make a Highly Versatile Soda Blaster that you can use with different types of abrasives such as baking soda, blasting media, and sand or different combinations of these abrasives depending on your need. For those of you who aren't quite sure what what a soda blaster is, it is sorta like a light duty sand blaster that uses baking soda in place of sand. It is used to clean small metal parts such as nuts, bolts, and jewelry. Most of the parts used are available at Lowes for under $25.

Parts

1. Mason Jar with lid
2. 6 Washers
3. 1/8"x3" galvanized nipple (You can also use brass, I had galvanized laying around.)
4. 1/8"x1 1/2" brass nipple
5. 1/8" Close nipple
6. 1/8" tee
7. 1/8" Coupling
8. Part of an old R/C remote antenna aprox. 3-4" long
9. Tubing ( I don't know exactly what size as long as the OD is just smaller than the 1/8" coupling)
10. Air gun that has 1/8" connector
11. Electrical Tape

Tools

1. Drill Press
2. Drill Bit 25/64"
3. Drill Bit 11/64"

Wrap one end of the antenna in electrical tape until it fits firmly into the 1/8"x1 1/2" brass nipple.

Connect the 1/8" Close nipple,1/8" tee, and the 1/8"x3" galvanized nipple as shown in the pictures above.

Drill the 25/64" hole close to the center of the Mason Jar's lid. Next drill 4 11/64" holes around 25/64" hole. (it does not matter the size of the 11/64" holes they are just vents so experiment with different sizes to fit your need)

Next put the lid on the close nipple be sure to put the screw ring around the nipple first (or else you'll be taking it apart). Then put the 6 washers on the nipple and then tighten the coupling to sandwich everything together. Lastly insert the tube into the coupling (if your tubing is tight enough to stay in by its self go to the next step). Then tape around it to seal and hold the tube in place.

You now have a highly versatile soda blaster that you can use with different types of abrasives such as baking soda, blasting media, and sand or different combinations of these abrasives depending on your need.

How To Use

SAFETY INFO: Please be sure to wear eye protection and a respirator before starting.

1. First put baking soda in the mason jar then screw it on to the blaster
2. Next take off the galvanized nipple off the tee and slide the antenna tube in and out to adjust the flow of baking soda.
3. Hook up to an air supply and go!

Troubleshooting

1. Not enough baking soda coming out? upgrade to a larger tube.
2. Not enough vacuum? add a longer nozzle
