spring for a 400psi PCP?
Posted: Fri Jul 01, 2011 7:43 pm
i am currently attempting to make a low powered PCP air gun and am stuck on what spring i need and where i can get it
the hammer valve seat diameter is 10mm
pressure when full 400psi
hammer weight 60g
hammer length 4.5cm
distance between valve and back of hammer tube 12.5cm
OD of the spring needed 13mm
with all that in mind is there anyone here who is smart enough to figure out what spring i need? and where i could get said spring? also if it helps i have tested dropping the hammer down a 65cm tube onto the the valve and got to open the valve almost to just the right amount. if someone can help i may possibly have an alright gun to show you guys sometime soon, and if you like i can post pics of what i have so far, but ill have to wait for the internet to go back to full speed
cheers
