Blasting Media

I use glass beads for the material that isn't terribly rusted and where I want a smoother finish.  I use the medium aluminum oxide for the tougher stuff that requires more cutting power.

I have good success with crushed walnut shells. Don't seem to overheat like some of the other medias.

That's interesting vinny,

I'll have to get plastic media, what source have you used to buy the plastic beads from?

Does the plastic prevent heat build up and warpage in thinner gauge sheetmetal as well ?

I've used crushed auto glass, silica sand and black beauty.
About 15 years ago I purchased a ScatBlast cabinet and vacuum from TP Tools.
One of the best investments I ever made. I'm still on the first set of sleeves, but have a spare set on hand. I have all the consumables on hand as spares. I found out that the plastic film the local HyVee uses to protect fresh flowers works great as a liner to protect the window from getting all cloudy. I wipe the dust off the window with a damp towel, let it dry and tape a piece of the plastic on the inside with 3M blue masking tape that doesn't leave a residue. Needless to say, the women in my life got flowers, they never knew why.......kills two birds with one stone....

I have a gravity feed canister blaster as well, I've built a tent inside my "shop" out of poly sheeting so I can blast larger objects. I wear a paint respirator and a hood when blasting in my tent.
