slightly similar to what i tried to make but failed, but your design looks like it might work, altho i am unsure that you will get very good performance from it, how many psi you plan to run it on?

2.5MPa is the listed as the "periodic test pressure"... this is a proof pressure, not a working pressure. The label also states the working pressure to be 1036KPa @ 23C +/- 2C. Where's the confusion? that is all clear, the main question was if it would be safe to take it to the periodic test pressu...

do you mean amazing as in really really hard?

i made this a while ago, had a bit of power for its size and considering it was a combustion

ah ok yea i didn't know the capitals mattered, but yes is it MPa not mPa, as for sittings i have cut down the old valve a bit and there is a thread where the pressure gauge was and it fits the nosily from a blow gun so maybe i could use that to attach a hose to like you do with a fridge compressor. ...

i was thinking of epoxying the inside, and its a powder type that i found at an old motel that is destined for destruction, and yes i will only use it if i am satisfied that i can connect it properly, not sure if i will be able to or not

i have a steel fire extinguisher that has written on it that is has been tested to 2.5mpa (362psi), would it be safe to take it to that or similar pressure on a regular basis? how much would be a safe pressure to use it at? i had a look inside and it only has surface rust and very little at that so ...

hmm yea, i really hate Australian laws, very nice looking gun

hybrid? could be kinda fun

take a look at this

wish i could make my pen guns serviceable, fixed my one the other day but uses sh!t rubber so its arealdy started to leak

With pen guns, "across the room" is the best you can hope for

iv hit my neighbors shed from at least 30m away

commenting so i can get emails on the updates, but i may as well say it looks like a fantastic design and i would be completely happy to give the end result a home out of the kindness of my heart 8)
i think you have motivated me to get of my but and go fix my pen gun i make from a parker pen

ha ha yea that would be hard im kinda a volunteer, but they do give me $20 for fuel and food

ha ha actually i think it would have been easier to clean if it had of been hard because it was outside, instead i had to dig up all the dirt and dispose it don't think my boss was to happy
