Well il start the hunt in my local junkyard.

U need to remember my fitting was only in a turn and a half. Also i put the pieces together and put the weld around the edges to make a shell of sorts[/list]

Where can one obtain a fridge compressor. I dont have a spare fridge at the moment.

I went with a half inch barrel, i used ball bearings i have from some magnetix kits i got a garage sale, i have about 1000 of them now. To fill it i use my friends air compressor and can get 200psi, performance is good, plenty of power but only so-so accuracy because of the smooth bore.

OK well i took out the fitting, it was hard, but it came out, i went to lowes and got the same reducer in black steel and it works fine now.

Okay thanks for the input im probably gonna go with a .5in barell then i can use marbles and ball bearings

Im not so sure...it takes five pumps with a bike pump to get it to 120psi im guess it will ta ke about thirty pumps

GunFreak- im still gonna be able to get it out, i just wanted i quick solution for some initial testing, i intend to properly fix it as soon as i get time to run up to lowes, though i have no idea what fitting to get, but i will play with the fittings till i find something that works.

At the moment, I am building my first QEV gun. My current setup is a 3/4in QEV with a 6in long 3/4 chamber and a 1/4in ball valve pilot. I hope to run it at 300psi+ once i get my shock pump. I still haven't decided on a barrel size. Any tips to make it more efficient or input on what barrel would be...

Well jb weld and turning the crap out of it did the trick. No more leaks

Decided to go the "wrong" way. Covered the fitting in JB weld and twisted it in as far as i could, got it in pretty good without jb weld and it had a slow leak so I jb welded it and am waiting for it to dry then will try again.

Hello, I've just started my first QEV air gun build and have run into an issue. The threads on my 3/4 to 1/2 (used for making my pilot) to fit into the QEV very well, I can only get about a turn. Both pieces are 3/4 and I don't know why they have different threads. I would appreciate any help with f...
