this is a revised version of my first piston valve by adding a blowgun and reducing pilot vloume(still needs work). the chamber is 3/4in copper pipe and the barrel is completely threaded but was surprisingly cheap being 1/4in bore and is 3 feet long. i found it in the lamp section of my hardware store as a wire housing for lamps. i havent got a chance to take any damage pics as i finished the enlarged chamber and barrel today. i have a smaller barrel and airchamber from an old gun with a pressure washer barrel for the barrel.
the piston is made of hot glue and has a rubber sealing face.

Looks good, but that pilot volume is HUGE, if you reduce it you will see a noticable power increase.

you should have seen it before. it was gigantic! and yeah im workin on it. as you may have known from my 1/2 coax project about a week ago im not very good at pistons

You should switch the blowgun with the schrader so it has a more gun type feel and it will probably increase you accuracy.

i was going to have a 90 degree elbow for the blow gun for that but that is a good idea, i will do that. cheers

cool looks good! its almost the same a what i was thinking of trying to make

As clemsonguy1125 said i think you need to re do the pilot side and you will see a noticable increase in power, combined with the new blowgun position and this think would be a great clean looking gun.

As clemsonguy1125 said i think if your re-did your pilot side and re-positioned the blowgun i think you will notice far better power and accuracy.

Edit; Sorry double post
