my little bro and i have been considering picking up a sand blaster, but i ran across a soda blaster which sounds as though it may be better suited for my needs. for those that don't know the soda blaster uses baking soda as the blasting media. i was hoping someone has used one to share some opinions. thanks guys | ||

I read a lot about them a few years for a project I was doing at work. They have quite a few advantages over sand blasting. The industrial outfits use a water/baking soda slurry, but I think the same advantages would apply. The baking soda is softer than sand and doesn't work harden the metal surface as much (a real problem with blasting sheet metal). The baking soda supposedly leaves a rust-resistant coating whereas sandblasted metal will rust almost immediately if not primed. There are some definite health hazards working with sand (silicosis- a lung disease). I think baking soda avoids that. | ||

That will be a good tool for doing small to medium size jobs. You can use the soda so that it doesn't warp sheet metal and switch to sand to blast rust out of tough areas. Biggest question will be your air source and dryer system. I would recommend being 40% over their recommended air supply minimum, and having the biggest, best air dryer you can afford to put on the system. And check into how much air pressure drop you get per ft/diameter. That will be important too. Make sure any sand you buy is for blasting, play sand and loose sand have too high of moisture content and irregular size particles that will clog tips. I use a paint respirator with a head sock and vented goggles. I tape any areas around the goggles with masking tape to seal them. Those blasting hoods are hot, unfiltered, fog up, and are very difficult to see out of. | ||

Cool! I just got a Harbor Freight handheld blasting gun, and was wondering what I should feed it. I was figuring sand, or crushed walnut shells if I could find them. Thats another nice option, wonder if it will work with my cheapo gun. Any other suggestions for cheap, available, and effective blasting media? | ||

I thought this was going to be about these kind of soda blasters! http://youtube.com/watch?v=hKoB0MHVBvM  |
