very nicely done, find someone with a chrony!

either that or we have to find an easier more accesible standard of comparing BB velocity...

I was unaware that this was your design. You had a T valve, the chamber under the barrel, a different stock, etc.

Nah, It was a Coax, the thing under the barrel was a shock pump and it used the dual tee method to fill and vent the pilot. But it doesn't matter mate. What you made looks great, people love it and is very, very powerful. Good thing is, is because I thought up the concept (I know I wasn't the very 1st person to use this design. I've just never seen it on spudfiles so I can't take credit for it. It had been used before. I'm just glad an idea I had worked). I can't wait untill I build to improve on this design. I've got a few ideas in mind.

Anyways mate, sorry for the hard feelings, I just took it really wrong.

All the best.

Thats it there:

bah. i still like both of yours.

still, ive been convinced to build one of these.

i went to the hardware store today and picked up a peice of 3/4 inch galvanized steel pipe. dang was it heavy. i basically went and found all the parts i would need.

im torn between a blowgun for the trigger or a ball valve. ill proboably go for the ballvalve because its safer..........

im also going to add a hop-up (adjustable) and some kind of bolt action breech.

gaaa its so dang expensive.

Yeah thats why it's taken my a while to build this gun. Money is a suuuuch problem :( haha. I bought a 9/32 barrel 2 days ago. I had it sleeved in my marble gun just so I could see the the bb's went at 100psi. It all worked fine....Untill I cranked it to 120psi and it blew the bb barrel out like a harpoon, it hit a wall and totally compacted. Now I gotta fork out more cash and get another barrel. Bah so not happy haha. :evil:

I just meant how you designed the gun, not screwing the fittings together.

I was able to actuate the piston with the ball valve, the schrader valve, or the blowgun. The shock pump is screwed onto the schrader valve.
