Im going to experiment with an accidentle nozzle i found. Some bags of water baloons come with a cheap plastic nozzle right? the ones i bought recently had one, with a threaded nozzle! and its roughly 22mm inside, and fits directly (well, with a little bodging) onto my Release valve. i think the nozzle's hole is about 5 or 6 mm wide, but ive still got my blanking disc ill drill to 4mm otherwise
I've seen what you're talking about before. They should work fine as nozzles. They even have a conical part so they're a little better than straight caps or blanking discs.
Let us know how well the gun works. Sounds like you have it done.
12 bar (about 175 PSI for those who don't know) is pretty high pressure so I'd imagine it would be incredibly effective at dishing out water. It's really too bad that you guys couldn't keep your creations but given their price I don't blame the college. I wish I had access to stuff like that... maybe I should get a job working for a plumber.devvo wrote:in my third year at college doing heating and vent we had finished all our coursework a few months early so we could do what we wanted so we built our own, thats why i bring up the expansion vessel, you get them from 500ml to massive 100L ones, in our class of 30 we built 6 silly powerful guns, one guy had a 12L expansion vessel strapped to his back which he charged up to 12 bar with a motorised test pump, with a 28mm barrel he blew everyone away, of course not everyone has free materials like we did, i just wish we could of kept them but the college wouldn't let us run off with hundereds of pounds of fittings!
