shoestring blasting setup

[Matchless]

I have only got a bag of glass bead for the smaller cabinet and the crushed glass that was in the pot when I got it secondhand, I will look around, want something aggressive for rusty steel in this cabinet, just don't want to buy a load of something that I cannot get on with, have plenty of air from my three phase Hydrovane 33 plus two tanks in line, pressure does not seem to drop from around 90-100psi when blasting, but hard to see but will mark the pressure gauge with a sharpie tomorrow,

I run mine without pressure gauges probably between 90 to 125 psi pressure

Since I put my grit valve it doesn't seem to matter what way I leave it but with the stops I do it anyway.
If I get a blockage it's always at the nozzle and I've mine setup so that I can unscrew it inside the cabinet without the need for tools.
I never have to touch the pot now, at worst I take the nozzle off and let the pipe full of grit blow through.

I use Jblast supafine (copper slag) and reuse it until it's dust or if I am doing something outside the cabinet then it gets used up that way.
If I need to do something with heavy scale / rust, then I use new jblast

realy the only time you would get a blockage at the nozzle is of bits of media that's not consistent and got bits of paint or rust flakes in if it hasn't been sieved or the blast pipe is getting flooded with 2 much media and blocking the jet
