Pen Gun Wont Seal
Posted: Thu Oct 02, 2008 1:44 pm
hello, i made a pen gun like jacks, and it wouldn't leak air out the barrel when i used my lips to test the seal, but when i use my bike pump, or the aircompressor regulated down to like 5 PSI, air just leaks out the barrel.
does anyone know if i need to make a small homemade pump for this pen gun.
i know the piston moves foward when air is put through the schrader valve. but when i take the air pump source off the schrader all the air comes out.
did you guys that built similar pen guns have this problem? and if so what did you do to fix it?
Thank You For Your Time
