I find it hard to say much against such a nice piece of work, except perhaps my concerns about unleashing 800+ psi of freezing cold gas into PVC pipe.

Apart from that, I can say I would much rather it sat in my cupboard than yours.

Why copper pipe? I think that the high pressure hose he's using now looks pretty bad@$$.

I was a little apprehensive at first as well.Luckily the amount that is actually released into the barrel isn't enough to do much more than generate 80-90psi.Even during rapid fire none of the plastic even gets cold.To chill things down I have to tip the tank over and drain it out.

The only thing I would change is replacing the hose with copper tubing (no snags), and give it some leaf-stencil camo if you feel it would give an advantage.


Considering the high pressure hoses can be picked up at lowes for about $5.I think it's worth the possibility of a snag over having to cut out and flare a copper tube whenever one breaks.Plus the added benefit of a pressure hose is that if it does rupture it will start to hiss before it actually blows the line.

I also have debated doing a tiger strip camo job.I don't know if I will yet or not.It depends on how well it performs at practice this weekend.

Have you tried to fix the leak with some lubricant?

The problem lies in the valve sealing face.It needs to be polished out.Water valves just aren't designed to gas valve tolerances.

very nice looking and clean an excelent job. haven't seen this one on spec-ops yet, are you going to post it there also? everyone will be drooling over it,

Yep I need too. My last one had them going as well.

I think this is the most practical paintball cannon I've seen here on Spudfiles. A big A+ For its shocking cool factor and your craftsmanship.

I have a silly question/suggestion and its probably uncalled for but before i get to that i would like to congratulate you on an amazing job, on all fronts design construction, practicality, however it is with the application of such a weapon where my question/suggestion comes in, could it be possible to use the pressure washer and co2 setup , by means of a quick connect and inline regulator to supply high pressure regulated co2 to a small to medium sized launcher, which would eliminate the need to build a separate air system for various cannons. :idea: it struck me because I'm planning a medium sized
cannon but i don't want to lug around a tank on it, which brings me to my next question would the co2 degrade the seals on the pressure washer handle?

If you mean that you want to interchange the valves between separate guns?Then that is entirely possible.My first design counted on switching the valve between different gun setups.I eventually decided on its current config. and change the barrels/actions rather than the valve.


which brings me to my next question would the co2 degrade the seals on the pressure washer handle?


Depending upon the valve.Mine is all steel and brass,I have no seals except for an o-ring that is behind the threads and that seal will never see liquid Co2.To check for certain that your valve is okay you will have to tear apart a couple of valves.Don't worry, if you can understand a hammer valve then you got it down.Pressure washer valves aren't complicated at all.
