Build your own sandblaster cabinet!
« on: April 08, 2009, 11:32:08 PM »

There's a few cheaper ways of doing this, but if you have the motivation a blaster cabinet can be a great thing to have.  I decided to build rather than buy so I could add a few things, and make sure it would be large enough to suit my needs.  I just use a $15 husky siphon feed gun.

Here's a shot of the whole thing.  Important points:
1.  Trough like base to collect the media.
2.  Slanted roof to make viewing easier.
3.  Cut off sweat shirt sleeves stapled to the arm holes to keep keep media inside.
4.  The windows get dusty, but don't really scratch.  Glass is easier to wipe than plexi.


Added an attached water/oil separator.  Wet air will clog the gun, and this also provides an easy point to connect your air hose on the outside of the cabinet.


This is a dirt bike air filter boot I happened to have.  Conveniently it perfectly fits my shopvac.  Hooking a shopvac to the cabinet during operation keeps dust from blowing and allows dust to settle faster when you are ready to open it up.  If you're worried about your shop vac motor you can add some water to the bottom of the vac to help keep dust down.  Mine has been fine, although the vac filter does need periodic cleaning.


Inside shot showing the dirt bike air filter.  It's just a mesh screen, but it seems fine enough to block the media.  As the media breaks down it turns to a finer dust and passes through the mesh.  Also take a look at the edge where the door opens.  I added a line of foam weather stripping all around to form a better seal when the door closes.


Here's the inside.  Made a grate out of rebar and screening to set parts on.  Also has a length of air hose permanently installed for easy setup.  Also included a flourescent light inside the cabinet to increase visibility when the windows get dusty.

What pressure are you running and what media? I know if you shoot glassoxide at anything above 70psi or so it seems to turn to a useless dust much faster, a pressure regulator is a good thing to have on blast cabinets.

My air compressor can maintain ~ 60-70 psi with continuous use, and has a regulator on it.  Higher pressures degrade the media faster, but also clean faster and leave a different surface finish.

yea dust explosion is a threat with some stuff, but this is sand, it doesn't really burn, ever.

now put a cat in there and blast it

did you mean like a meow meow?

at my work we do some media blasting, and guys always want to run the glass bead at 100psi because theyre in a hurry, but it turns it to useless dust so damn quickly.

If you're blasting say, oh I dunno, a metal part, then there is some level of metal dust in the cabinet. Carry on.

no its hydrocarbons

and as for metal dust burning, steel-no, aluminum-no, titanium-no, sodium-yes, magnesium-yes.

flour mills and shit exploding is because its a hydrocarbon, sugar will burn. metal will readily oxidize if its super hot in a oxygen atmosphere (like a cutting torch nozzel)

as far as glass-no, silicon dioxide(sand)-no

That's interesting about static electricity.  Wood is an electrical insulator, so it can build up with static on the surface, but it will never shock you as  it does not conduct.  I guess metal cabinets have to worry about that.

I've personally seen aluminum dust burn. Anything will burn if it's hot enough. That's the problem. And a spark is really high temp, hence if the conditions are right, you get an explosion.

Lol do you know how many manufacturing facilities are no more becuase of aluminum dust?  Aluminum dust (along with many others) is like a bomb.

dude you guys.  The sand blaster does not explode, trust me.  I've used it for many hours.  There is NOT even enough dust to pose a risk, it's not flammable, and the fluorescent light is not an ignition source.  The motor in the shop vac would be a bigger concern IF it was flammable at all.

That's like, if you lit a cigarette, on a beach, while the wind was blowing... you could blow up.  preeetty unlikely

I just got back from harbor freight, and their cabinets run $199. I'm not sure a 15 inch rim could fit in those very well.
