I finally finished the new version of Lauren. This time around I used all pressure rated parts, and a piston valve (which will be piloted later by a sprinkler valve). I haven't got a chance just yet to fire it because of sealing problems with the piston. But, it has a 4' by 1 1/2' chamber, 2" piston valve porting to 1.5", with a 3"x3 1/2' barrel. BTW, I aired up Lauren V1 to 35 PSI, and got a golf ball about 200 or 300 yards. Hope you like!
(could someone tell me how to get my text centered? The tag won't work when I type it)

i know that, but that really won't matter much because it isn't being pressurized.

Oh it is... trust me. Even more so when your ammo is a tight fit.
Just be careful.

I wouldnt worry about. thats a very nice gun. what exactly do you shoot with it?

Yeah, I thought about that. But it won't be pressurized very long plus I'll mainly be shooting my dad's beer cans with a wad of rag behind it. And I'm going to get a coupling for a 2" barrel soon too.

The 1.5" piston porting is on the very small size for a 3" barrel. Lemi do da math...
The piston has about 1/4 the flow of the barrel. It should work fairly nicely for a 2" though
Do not look back, and grieve over the past, for it is gone;
Do not be troubled about the future, for it has not yet come;
Live life in the present, and make it so beautiful that it will be worth remembering.

Nice what are you using for a piston,

why doesn't it seal,


post some pics of the piston so we can help you debug and get this thing up to 125 psi

Yes, agreeing. Now Lauren looks stupendous. This is something you should be proud of. But, again, tell us why it won't seal and see if we can help.
