Has anyone here had a go at soda blasting ? I know it can be a messy job but would be interested to set up a wet / dustless system , possibly to use in a cabinet . Anyone ???
I've done a few carbs. Dry, In a cabinet with ventilation. Just bought 10kg of cooking grade bicarbonate of soda off eBay I think. Reused the media a few times. Worked ok.
Coarse grain sodium bicarbonate. Baking soda. Quite important to use the coarse grain because the cleaning action is the crystals smashing themselves and blowing up on the piece. Which is why you can't use it twice!
If I was going to build (or buy) a shot blasting machine, it would definitely be a wet one.
