Has any one on here built a large pressurized sandblaster? I've got a heavy duty 50 gal water tank id like to repropose. 10 gal blaster doesn't do much but piss me off.
i think most water tanks are built to hold under 100psi, do you use a blast cabinet? i have a factory built blaster and have used a very nice blast cabint lots, also some big ones to do big rig trailers. found a link and a picture http://www.vintageprojects.com/metal-welding/SandBlaster-plans.pdf
