Hey again guys! I just made a hot glue piston for my marble gun.

It is a 1" piston that is 3" long. It goes to a 1/2" barrel.

Should I glue the neoprene onto the front, use a screw, or both?
Also, what kind of a screw should I use, wood screw or metal screw?

Also, what kind of lube should I use? I have both white lithium and gun oil. Bear in mind that this actuates with a 1" sprinkler valve and it has a silencer that I don't really want to gunk up.

I use Stick N Seal, it works really well for sticking rubber on pistons. I don't know about gun oil, but white lithium seems to be a proven favorite.

:white stuff pours out of piston: "What is that? It looks like milk."
"....<i>Well...</i> it's not milk."

YAAAAAAAAYYYY WE'RE DOOMED!
