wyz, think you can draw up a diagram of how your trigger and hammer work?


try this and check his youtube channel becuase he has a pretty good hammer valve rifle :D

What I meant was more how does the entire thing function. Pretty much a cutaway of the entire trigger + hammer + impact point on the blowgun.


Try this it is very simple, i tried to build one but i gave up on mine because it came to fiddly and everything kept braking lol hhaha

It will work, but it's not really a hammer valve, rather a mechanically actuated exhaust valve.

ah ok thanks, i think mine is about 10mm, wasnt sure if mine was to big for a decent sized spring/hammer to open, but i guess if you can get the 8mm one to work with twice the pressure i guess it shouldnt be to hard
