I found this when I was just browsing some surf music. I thought somebody might be interested. It's for vintage carburettors, but it might be useful for blasting small spots on the body, or other small parts. And, even thought it says you don't need a blasting cabinet, I think even a cheaply made one would help keep the dust to a minimum, even though you can just wash the soda dust away.

Could you use anything else besides baking soda? Salt is more abrasive, because it has a cubic crystal shape, but it could also become corrosive. I think salt would work very well, if you were careful.

Cool tool! Thanks for posting.

Oh HELL yeah! I am thinking that this would be perfect for Marine or or small carbs. Thanks for sharing....

You can't do any of that with a schmart fone. You gotta keep the grassroots or sgade-tree guy in business, no matter what technology is up to. Technology sucks- go out and grill tour brats over charcoal.

Nice!
