Default FrankenBlaster

I had been wanting a sandblaster for a while, (I need it to cut my windshield), but nothing really impressed me, the high dollar units were just that, high dollar, so I thought why not make one.

After extensive research I found and bought plans off the internet, PABlaster.com. I call it "Frankenblaster", made it from an old 80 gal water heater (had to cut it about 10 inches shorter, too big) , a concoction of fittings, a dolly and other various parts.

Tried it out with regular masonry sand just to get the pressures right, man this thing is great. Looks ugly, but works like a charm, can't wait to start buying other types of abrasive media. I attached samples of what I did with it.

BTW, the tank only holds about 7 to 10 PSI, so before I get bombarded with any structural, strength or water heater dangers, the tank hold very little pressure.

Does it work? My blaster averages about 90PSI.

7-10 seems a little weak.

There is a special mask that looks like the foam tape; I guess the sand bounces off. I used to cut patterns for the sandblasted wood signs when I was in the sign biz, but never actually blasted the signs. I guess it would work on glass as well.

Some specifics, yes it does run 7-10 psi in the tank, but at the gun you can run anywhere from 60 to 90 PSI, the trim in the pic was blasted using 60 psi, and the bumper was blasted at 90 psi using masonry sand

It uses both the siphon feed and pressure pot systems at the same time, so imagine, the tank, running at 7 psi forces the sand out and feeds it to the gun running at pressure of 60-90 PSI depending on what you are blasting and with what media you are using.

You can make em out of anything from propane tanks to fire extinguishers to get this plastic buckets (with a lid)!!. Almost sounds like "running engine on water" but it does work.

Wow, cool, thanks. This beats the hell out of "what's your favorite color" posts. I marked the noted link as I need to build one of these also.

THANKS

I know, sometimes good posts will end up in oblivion before the first day..... I'll rename the thread to "rat rod sandblaster" to keep it up-top; come to think of it the tank looks really ratty!

So what is your favorite color wvenfield?

So the 7-10psi pushes the grit to the gun which is then converting it to a siphon type? What cfm does it need?

Not to be a dick, but please leave the sand alone...I know its cheap. Black beauty is $11.50 per 100lbs, green diamond is $10.00 per 100lbs...were you just using it for a quick test? Don't want to come off as a punk...

i hear ya, i was using the sand cause i personally didn't think this thing was going to work, you see when you bought the plans, there really isn't any one right way to do it, you use materials you have "laying around". So since FrankenBlaster was built straying away from what the pictures pictures looked like, i needed to make sure i didn't buy the good stuff waste it, and realize it wasn't going to work. So "Tried it out with regular masonry sand just to get the pressures right" and make sure it works. I am actually looking forward to using black beauty and anything esle out there except sand.

Hhmm, well the gun needs 9 cfm at 90 psi, the gun is a 13 dollar siphon feed gun from homedepot but its not being used striclty as a siphon gun, that being said, i would gestimate about 7 cfm at 80 psi at the gun with 7 psi in the tank....make sense?

If anyone is concerned about CFM you can downsize the gun orifice to cut air consumption. They wear out and need replaced periodically anyway.

Nice setup, bet the small amount of pressure eliminates uneven media feed that suction blast is notorious for. Very cool.

Anywhere on the net that plans like this are free???? Seems like everything can be found that way these days.....(meaning that I am sure the guy selling the plans found them free somewhere himself)...........and my Paypal is currently jacked.
