Used this today and I have to say I am impressed. I have a craftsman portable sandblaster that is probably 30years old and the nozzle has been doing poorly for a few years now but I don’t sandblast a lot so I have put up with it. For small items I have a harbor freight cabinet, the cabinet is decent, the gun stinks. With both guns there is a small band where it will siphon up the sand instead of blow out the siphon tube, usually around 90psi. There are adjustments on both so it can suck less or more, both literally and figuratively but they really make no difference.

I went with a 1/8” jet and 5/16 nozzle. Rated cfm is 21cfm at 80 psi from Big A’s. It is not a $40.00 gun but it doesn’t work like one. My main compressor will put out 17.5cfm at 100psi and runs up to 175psi, the backup is 7.1cfm at 90psi and will do 120psi. The flow rating they list is pretty much right on. With the main alone it will bring the pressure down to around 85psi and actually it still is pretty fast at getting the work done. If I add the back up I can get through 50lbs of sand before it kicks in the backup at 90 pounds and in the time it takes to do the rest of the pot, 30lbs, the pressure will build back to just about 120. The backup usually shuts off within a few seconds of finishing.

This gun does not care if it running at 175 or 80, it just sends out a stream of sand and when you let off the trigger about a tablespoon falls out of it. You can see the stream the whole time. I never had a clog and I knocked out the snowblower parts shown in 2-3 hours but that includes as much time blasting as screening sand to reuse.

Got to use the Secret Santa gift as well cordless drill in one hand and cordless driver in the other.:good2:

Got the primer coat on. JD recommends 36 hr dry time on the primer before top coating.

Patience, patience.

How much does a simple sanding outfit like this cost? Do you pull your air off of a regular compressor tank?

The gun was $120.00,the link takes you there. The pot, what they call the tank for the sand, I’m not sure, but if you search their site I am sure they have them. Mine is old I probably paid $50.00back then. Yes for the small guns the regular compressor works fine. I have only had the big compressor a few years, up until then what I called the backup compressor above was the only compressor I had. You wouldn’t want to try to make a living this way but it works.

So you’re saying I need a gun and a pot that the sand is kept in, then use my compressor for the air pressure. Don’t need anything big, would be for using around the house on rusty objects. Nothing extreme or commercial. One more question, do you use this over a tarp for the mess, is the sand or material biodegradable?

If it is something quick I just do it on the lawn. Big projects,on a tarp because I can recapture and reuse the sand. I typically use black blast from menards which I think is a Silca sand. It really isn’t biodegradable but it is just sand. It would take a lot to get deep in the lawn. By small I mean much less than 50lbs of sand. Anything more than that I would reuse the sand.
