Hi everybody
As most of you knows, I found a way to build a simple hammer valve using a blowgun. So I used the valve I showed here: http://www.spudfiles.com/forums/hammer- ... 23202.html to make a simple pcp gun, just to see the power, and at 400 psi it´s very decent with a pellet, pretty good compare to commercial pellet guns :P . The chamber isn´t big, so I can charge it with my shock pump. I also combined the recock with reload, but I didn´t put a magazine on it, maybe later I will add a revolver style magazine.
I will use a bigger chamber and a better stock on this gun and use more pressure(about 800 psi?)
Didn´t use a lathe or mill, looks like I didn´t really need to use them either :roll: . Yeah I know I need to paint it, but as I´m not sure if I´m going change it more or not, so doesn´t worth to paint it now.

Machine tools help, but with some creativity and a lot of epoxy, much can be achieved - and this proves it nicely, good job! How many useful shots do you get per 400 psi fill?
more pressure(about 800 psi?)


Beyond 500 the valve will probably start to leak...

I have taken this valve to 800, no leaks, but I wouldn´t use 800psi every time.
with 400psi, about 5 nice shoots, pressure drop of 20 to 25 psi between each shoots

yeah they are simple and you can get multi shot with it, and I really like making a realistic looking trigger :)

A lot of people have told me to combine the reload action and recocking the hammer actually :D but because this it's a little hard to pull the bolt, so later I will find a way to use a lever action to replace that, something like some FX airgun's bolt action :)

It looks fantastic but 800 psi in that thing feels like an accident waiting to happen...

its probably just the pics but it kinda looks like the brass part of the stock is right where your thumb would go passed
