Sand/Media Blasting
Any blasting gurus out there ?? I obtained anice cabinet from my neighbor and had a bunch of questions, like orfice sizes, the pick-up tube, changes for diffferent media types, etc.
Any help would be greatly appreciated.
I've already tweaked it a little- rebuilt the gun, new hoses and connections, new filter/regulator, played with different pressures and such. It runs pretty good, but I think it could run better
!!
Thanks.

might want to get an eastwood catalog. they have a little blasting chart with different abrasives and particles size etc. they sell the stuff as well.

the only blasting ive done is with sand, which worked well on rusted metal. dry air is very important. otherwise the sand gets wet and clumps up inside the pickup tube and nozzle.
get a foot pedal control valve if you dont have one. gets very tiring on the hand blasting parts for hours.-Josh

Thanks, Josh.
I've got the eastwood catalog and that's what I've been using as a reference. But-
Seeing as my cabinet was designed for sand (glass etching cabinet, kinda old, but works great
), I was wondering if going to glass bead would force me to change the orfice sizes in the pick-up tube, the vent size or the gun nozzles, or if any of it matters as long as your psi matches your nozzle ID ??
BTW, I hear using real sand isn't recommended because it causes a lung disease

Upgrading my Compressor
Hi smokeydoge
I glass bead gun parts & I got my plans, sizing info & jets + tips from SkatBlast Co.
With the 7 to 15 CFM unit, I used the small jets & Nozzles for that. Now with a big 2 stage, I can blast at 145 psi & 27 to 32 CFM. I had to buy the large kit to get any performance.
I tried to just let the glass beads open the works up, but no go it was the big nozzle set, that I need with my new CFM rate.
Sand Could ruin a fine Gun or auto part + silicosis is a bad lung problem with using sand.
