Here is some info about soda blasters.
A guy named "mattythies" has DIY plans for a soda blaster. It's mentioned in this thread: http://www.nastyz28.com/forum/showthread.php?t=2715
The thread is from July 2004, but I'll join the forum and ask him for the plans and for permission to post the plans here if they are still available.
AllSource sells a Soda Blaster Attachment Kit for $150 and you can get one at Northern Tool: http://www.northerntool.com/webapp/w...6065_200366065
Ace makes a 10lb. portable soda blaster for $249: http://www.ace-sandblasting.com/soda-blasting.html
as well as their more expensive soda blasters previously mentioned.
Here's United States Patent 7134945, Soda blasting apparatus:

That page also cites other related patents with links to them. No patent was found for Eastwood, so it must not yet be granted. If somebody has a commercial soda blaster, it would be illuminating to know what patents they claim for their device.
Here's a page that discusses a 1941 patent (2261565) for soda blasting and compares it to Buster Blasters' product which uses U.S. Patent 7134945 mentined above: http://sodaworks.com/pages/Research.php

A few questions for discussion?
1. How effective is the AllSource kit and how does it compare to the one offered by Eastwood? I would think that with Eastwood claiming its own patent, the devices should be different.
2. How do the $249 Ace portable soda blaster and the Eastwood $300 soda blaster compare?
