Hey Jeff, I don't have a sand blaster yet, however from what I have seen of other peoples I would get one that pressureizes the sand tank too. High humidity or any moisture in the sand can cause sand feed be erratic with only suction feed. SLEEPY

I have a gravity feed that cost me around 75-80 bucks. Works great for the smaller projects. It does use a lot of air, though.

One thing I did was try to reuse the sand. I took a piece of toolbox liner (the rubbery mesh kind) and used it to strain the chunkies out. did o.k. for me.

Jeff, The 200 dollar units are much better than the 10 dollar suction units. They are fine for small parts.......If you are thinking of larger projects like stock clips, It will work, but it's an all day job..........just really not up to the task.

Unfortunatly, the next step up is major bucks......But with out it, you won't be able to take on outside jobs........your time would exceed the value of the job....

If I need a spindle blasted, like right now, I would use the small tank......otherwise, everything goes to the blasters shop........

Good luck

I have done way more than my share of sandblasting... if it doesn't fit in a cabinette blaster... it goes to a blasting shop!

Or you can build your own bigger and better for less than a harbor freight blaster. Heres pics of mine that I built a few years ago and it works great!!!
Everything can be purchased at you local hardware store except you`ll probably have to order the gun and nozzles. Mine uses a ALC gun that was like $60 but I ordered it through my auto parts store so I`m sure it was marked up a bit. Air peg and dryer are cheap Walmart units, hose is 3/4" 300 psi AG hose, 3 1/2" ball valves, and misc steel pipe fittings to get it all plumbed like you see in the pics. The stand was salvaged from a junk Knipco heater...and don`t forget to slap a racing decal on there to make it look official. Hope this helps some people out there who can`t afford the $400 blasters like me.

that looks easy enough, air in the top, with a t- down to a t on the bottom where sand comes out.

big question for you is what do you have for a compressor?? I have a single stage unit upright oil type, 60 gallon, but im not sure how long it could maintain 100 psi while just blowing air out??

is 100 about what you regulate it at??

thanks for the pics, thats what Ill do if my compressor will work it, do you do frames, bodies etc?? I want to do my whole car so its like new..

I have a 7.5 hp 80 gal 2 stage 175 psi C-Aire compressor...and it runs constantly, you could fry an egg on the pump after awhile of blasting. I just blast my own stuff in my driveway in front of my garage...the neighbors really love me. I regulate it to 100psi at the gauge on the blaster tank and I use a 5/32 Sandy Jet nozzle. My buddy has a 60gal 125 psi single stage and when he borrows it, it works but he has to stop and let it build up every now and then with the same 5/32 nozzle. They make 3/32, 1/8, 5/32, 3/16 nozzles that I know of...you could run a smaller nozzle and not stress your compressor out so much. A pressure blaster works 10 times better than a siphon blaster no matter how big your compressor is. If I was to make another one I would put a cross instead of the "T" fitting in the bottom with a plug so I could drain the sand easier or shove a rod up in there to clean it out if it gets plugged .Also mine had a deadman valve on the nozzle but that thing was a leaky piece of crap, I took it off and now I could really use another ball valve at the nozzle for on and off instead of running back and fourth to the tank. Get good silica sand and buy yourself a cheap blast hood cause you definately need it. I`ll send you some better pics than those tiny 59kb ones.
