Shot blasting nozzle

[brightspark]

It does help as just wanted to know if it cheaper to make one or buy a20 gallon one

depends on what size set up u are using if its only a 3mm jet your using u can knock one up for 5o quid or buy one for about 90 quid and change the jet there another £17 .00. i made my own also making a proper metering valve which is far superior to a ball valve, the blast hose 6mm nozzle and brass couplings i scored new for 50 quid the rest was for nothing
