Pump up QEV gun. (Homemade high pressure pump)

[Mitchza89]

Gday everyone,

This is my new proof-of-concept gun. It's a simple throw together. The pump I'm extremely happy with and the performance is just awesome.

Just to give an idea of the pump, the barrel is a meter long so it takes no time at all to get very high pressure. I plan to do a final copy tomorrow and take down the chamber even further.

Thanks guys!

Sweet! looks good but the pump will need reenforcement i assume.

[Mitchza89]

Yeah that will come with tomorrow's final production. I'm glad I used aluminum over copper. It's just so ridged. It doesn't bend what so ever. Perfect application I think.

I'm thinking of making high pressure pumps to sell.

R-i-g-h-t...

But seriously, nice attempt at a self contained launcher system, looking forward to seeing it finished

I have to ask, what is going on with that picture that Jack linked? I just dont get it...

I'm guessing he's holding the pump element between his thighs in order to take a photo of the end - either that or he has a substantial RoboCock^TM

Lol..

Nice job with a self contained launcher! Any ideas what pressures you can get out of the pump. A stand so you can force it against the ground while pumping would help

Jack you dirty minded person . That photo was so hard to take, it was the best one. In the other pics, I was naked trying to hold it with my old fella so count yourself lucky (am I kidding or not? )

with the length of it and the diameter, 400-500 doesn't at all seem out of the question.

With the qev and that length of barrel, I should see some nice results (hopefully)
