Thumbs down

umm hmmm, I have one. I'm so proud of it that I leave it out in the rain.
The only piece of it that is worth throwing away is the tank. The "gun" is the worst piece of junk to be billed as a "working tool" that I have ever seen, bar none. It uses a spring loaded roller to squeeze against a rubber tube as a valve. The threads on all of the parts are neither ASE or metric, as best I can tell. And the media gates are just junky ball-type shutoffs so they either jam half open or half shut about 50% of the time. If you want to build a knock-off that will work Boilerman, I recommend that you drop by HF & study that one as your example of precisely what NOT to do, then proceed in the opposite direction for every single component except possibly the tank. Even the paint sucks.
I bought mine to sandblast that old Delta bandsaw I restored 2 or 3 years ago and I fought it for the better part of a week. Then I picked up a little siphon-bucket type at a salvage store to finish the job. It is a far superior tool.

boilerman I built mine out of a propane tank,i used a 3/4 S.S.ball valve on the end of the blast hose.The tips I get a NAPA 3/32 out let whole.I used 1/2 air hose for the blast hose.The main thing you have to remember is to screen your sand,even the finest blasting sand will plug up the tip if you don't.Another good idea is to have a 3/32 welding rod with the flux knocked off to run into the tip when it plugs up....I've done alot of blasting with the little pot it works great....If you want I'll get some pics tomarrow nite and post them...But like cutter i leave mine out side not because I don't like it.just because....... I've got a job to do tomarrow so it will be in the evening if you want them.....

ok...score is tied 1 to 1....this will be made out of stuff i have ....yes i'm cheap and refuse to spend money , so with that said the nozzle will be pipe ...more than likely it will be 1/4 or 1/8 pipe nipple....the reason i think i need this ,beside the reason that a guy has have to have stuff is ...i noticed a bubble on the bed of my truck right above the rear tire ....so i figured i'll just wire wheel that and slap some paint on it ....well when i got done wire wheeling it i got a hole that i can put both fist through side by side ...so now i have a patch to put in before i bondo it ....just got to make it last 3 more years then another 5 after the 3 ...you know how it goes

I have one like the Northern , $89.00 at the travelin tool sale. I'm on my second one , plum wore out the first (5yrs) and when you look at the price of replacement sand hose , it's just cheaper to pick up another one and strip the old one for spare parts.

I agree, a small one I would buy. I did make mie but one like it cost a lot more and it made sense, I made shop rates building it. I buy 1/8 XH pipe nipples 6 inches long and cut in half for nozzels.
