couple of questions, steel piston

Unread postAuthor: pat123 » Wed Jun 04, 2008 1:22 pm

I am trying to decide on what to build next.

I just finished a 2inch piston with a one inch port. I have about 8ft of 4inch pvc and i was thinking about making a large gun. would a 1 inch port be too small for a 2 inch barrel an d a 4 inch chamber?

I also want to get biohazard working properly. I still have to tinker with that for a little bit.

I also want to make a steel shotgun. has anyone ever made a small steel piston? I want to make a 3/4 inch piston.

1" being the barrel or vent port? For a vent that is large enough, but if that is the size of the valve your knocking down some potential.

A steel shotgun would be awesome. I've seen several people make small steel shotguns. BTB really had them in a crave there for a while. Without a whole lot of tools the piston will prove tricky, but you should be able to do it in time.

the tee is 2inch but the port is 1 inch. this is still better than a modded sprinkler for this gun right?

my goal is to finish all three of these during the summer.
