i saw some nice homebuilt ones on youtube,yet another project for me... i used a large stand up glass beader doing antique auto restorations,got spoiled. one thing noteworthy is the different types of media. NEVER use sand in one of these,plastic media may take a bit longer to remove rust,but there is very little dust. makes seeing what your doing way easier. as far as sandblasting goes,we had a concrete silo full of sand,i wore a protective headpiece with fresh air being pumped in. i think the blast hose was 1 1/2,running 120 psi. it would knock you down from the pressure if you wern,t careful. dont miss those hot summer days blasting a chassis with 50 plus years of rust and crud on it.
