That medium might be too big for your ceramic nozzle. What is your pressure and how big is your air compressor tank. If you do not have enough capacity, it will use a tremendous amount of air very fast and you will end up with less media to blast at lower and lower pressures. I like to blast with at least 90 to 100 psi continuously. I have a big compressor and when I really get going, I have to stop to let the thing cool because it is running constantly. If it is coming out of your nozzle okay, then you are not getting enough pressure for continuous amounts of time.

its working good but the grit is too course, The sand goes right through, but the medium slag gets stuck in the gun.
if i had fine I would be good to go.

The compressor is working for sure but , im just doing small parts and pieces,

brackets,,etc


when i use the sand because its wet its coming out with a lot of moisture(actual water dripping off the part) which inturn is keeping the dust to almost nothing, kind of a happy accident

I use Black Blasting Crystal, it's Copper Slag, it is cheaper than Aluminum Oxide, $15 or $17 bucks for a 100 lb bag. Got it at Napa here locally...

Blasting Sand as inhabiting a BAG of Sand labeled BLASTING SAND, in a hardware store will NOT release Silica into the air as it is 99% quartz rock and river bed gravel, No silicone there, but it sure is NOT advisable to use when blasting sheet metal. The crap is HUGE, it's about 20 to 40 grit in size and way to big for what you need.

You need Copper slag or aluminum oxide...

On that blasting box... You put a link to...

It's not necessary to have that style really....

The ONLY advantage to using that box over using my style (Big open pot) is, if you dump it on it's side accidentally, you do not spill out any sand...

No reason to spend more than $25 bucks on a sand blaster as the quality does not come from the unit holding the sand, it comes from the Tip, the material and your HEAD.

Mine is a 3 gallon Open top container with a hose on the bottom that you can buy at Home Depot for $25 to $34 bucks. I'll even post a pic in a minute or two.

Good Luck!

Here are the pictures of the best blaster I've ever used. This is the same one I used 26 years ago on my 1946 Willy's...

Mmmmmm, I do love a good kosher hot dog. Good thing too because Passover is coming up

They used Baking Soda media with a pressure washer unit on Trucks last year to strip paint and rust off the body panels on their old Chevy truck project. Supposedly the great benefit of Soda blasting is that the surface can be painted over and it does not warp the thin sheet metal. it also has some properties that protected the surface and prevented flash rusting, even with the pressure washer application.

A pressurized tank should work better than a siphon action gun. I know a guy who made a pressure tank blaster from a propane tank, and said it worked very well. I have an attachment for my electric pressure washer and used it with sand to prep a-arms and spindles from my snowmobile for powdercoating. I found the siphon hose would plug up at the nozzle when the sand got wet.
