Think I've got it, drilled into the T and glued in a magnet strong enough to hold the balls down, but the spring still pushes them up.

Fired about 60 shots and it never missfired. :D

So after much sawing, drilling and threading here is the new Pump Action.

Folding stock worked out quite well, hinged parts just work on friction but stay in position ok. Still got to fit the lazer back on. Drilled some dimples on the slide for a textured effect.

Wow, I seem to have missed this before. Very cool... Is the power coming directly from your pressure washer handle? And what pressures are you using? I like the reload system. Original :) can't wait for the video!

I connect my compressor to the push fitting on the handle, so it's only 100psi.

So it seems wyz2285 was correct, it is firing 2 shots at once, I will try and fix this, hopefully simply
If it does so consistently...you've got burstfire!

Why change it? :D

Do you think that with some tweaking, you can make it consistently a burst or true semi-auto or something? Seems plausible that you could work something out with that. Very nice receiver design, by the way.

Maybe, but I like it as single shot. Maybe my next one will be select fire, I am thinking 1,2 or 3 burst, adjustable fire rate, and full auto options. My initial thought is a solenoid valve controlled by a timer to adjust feed rate.

Very nice, reminds me of the home brewed submachineguns used in Northern Ireland :D

Great gun :shock: how does it work thou? Is it just air passing threw a pressure washer trigger into a barrel? Or does it have a qev?

Just a burst of air through the trigger and it fires one ball. Nice and simple

Next add a pulse valve and an air piston to auto-load for you.
