Any one have an opinion on how well the suction sandblasters work? Would I be better off spending the money on a pressure pot type sandblaster? At this point I am only restoring one truck and not giving up my day job. My current compressor can generate approx. 8.5 to 9 CFM @ 90 psi. Thanks for the opinions.
I'm no sandblasting expert...but I've got about 20 hours on a small pressure pot I bought from Harbor Freight Tools. It is cheaply made (in my opinion), that is, the fittings are cheaply made. I bought several 5/8" ball valves and the blaster came with 5 or 6 tips. After realizing justr how important it really is to keep water out of the sand (ie GOOG quality water separator), it worked great. In fact its a pretty handy tool to have. Got mine for $60. Northern Tools has the same one for $149. This blaster will only handle fine sand. I tried the medium grit Black Bueaty but it just clogged. The larger the comp[ressor, the better, obviously. My compressor is a homeowners model and can do around 8cfm@90psi. Sandblaster will work with a little less than that. I used a friends compressor (large) to do my 8' plow and the blaster stripped paint and rust like....the wind. After many years of trying to sand rust, scrape rust, chemically strip rust and to no avail...then there was the sandblaster....

Well put. I couldn't agree more. :-) I would add that Eastwood markets a hand held hopper type unit called the "Speed Blaster" which I like very much for small work. I have also become a great fan of "glass bead" media.

Another excellent source is a company called ---Tip out of Ohio. I ordered a canister type and also a big enclosed cabinet type that I can put a fender in. Works sweet.
Deadeyedave, when you get it all done can I bring my toys over and Play???? LOL sounds like you're really going into bodywork, what are you building???? John
With a pressure blaster, you have some pressure forcing the sand out. If you get a clog, you can put the full pressure in the tank and force the clog out. If a suction type clogs, you have to try and back blow the problem into the hopper by covering the nozzle with your gloved hand.
My TIP 99 pressure blaster has never had a serious clog, but my cheap suction-type cabinet clogs all the time.
