A screw here....

Blow valve where the silonid was....

And NO epoxy....
EDIT:
This is a 1" orbits jar top valve. I installed a modded blow gun ( drilled bigger hole in the brass fitting), a pressure gauge and a schrader valve. The gauge and schrader are tapped into a steel nipple. I prefer the jar top because they are easier to modd.
The rest of the cannon is being painted..
