Homemade sandblaster questiono(s)

[sickytwisted]

Anybody know where I can get some plans? A guy on youtube sells plans for one but that takes away from the homemade aspect of it. Any help? I hope that I started this thread in the right spot. If not, I hope the mods direct me. In advance, thanx! Oh, and pardon the typo in my title.

Btw, i'm looking to make a pressure type, not a siphon type.

How about a hybrid

That's what I was looking for. Do you know about putting some kind of pressure release valve on that so that the tank doesn't explode?

Pressure release valve

I made one using the schematic posted above. I used an old air tank a friend was throwing out, cut off one end and welded it back on in reverse so I had a basin for filling with sand. No worries about blowing up the tank because there is only 7-10 psi in it. The way it works is the low pressure in the tank moves the sand up to the siphon gun where the high pressure airstream blasts it out. With the schematic and the pictures below you should be able to figure it out.

The basics on mine are a 0-15 psi regulator available from Surplus Center, a water separator/regulator from Amazon and a siphon gun from Home Depot. You shouldn't have more than $50 ******* in all of that.

Imma try it soon. 50 bucks in materials sounds low though, being that I can only find some mid level dryer/desiccants for about 100 bucks.

Look at the blaster in my photo album. I made that from materials I had on hand. It is a pressure feed but the only problem is that you can run the material out very fast.
If I redo it I will have a dump valve at the bottom that will dump the material into a bucket and then have a taller tank of material to feed from

I'll look at it and let you know what I think.

I couldn't find your the picture of your blaster rsanter.

I just made a large siphon type out of some good 3/4 plywood and sealed all the joints. But.... I used quick connects. That way I could just use it as a siphon type or, by hooking up a pressure pot, use it as the pressure type. Works great that way. Sometimes you need the power, other times you do not.
