Cartridge valve mods

I have a build going with a cartridge valve and wondered how you with cartridge valves went about enlarging the transfer port hole in the body?

Drill press, mill, hand drill. One thing i did with my cartridge valve FS pistol is making it run on cocker springs.

May be I should have been a little more specific, I was considering how if I drill through the bottom hole to the transfer hole, the hole size for the screw that retains the cartridge valve becomes oversize. Should I simply tap the valve to a larger size retaining screw?

I'd be real interested to know what it took to do that... Did you just drill out the hammer and RVA and add a shim for the RVA screw to push on, or what?

The valve i had to cut the spring a little, green spring. The hammer i tried to drill it out but since they are hardened. I couldnt get to far with out dulling my drill bit.

Confused... There is no pre-drilled hole in the body. The threaded hole at the front of the valve holds it in place using the grip frame screw. If you don't want to take the gun apart, you have to drill through the lower tube and up through it into the barrel tube. You end up with a new hole in the bottom tube.

Thanks Mad, the valve I have has the retaining screw and gas transfer port in the same plane, just like an old Sheridan valve, or a cocker valve. if I drill through the bottom tube in order to enlarge the gas transfer part of the body, the bottom hole where the retaining screw fits becomes oversize as well. I am thinking of just drilling before the hot work, which as I see it makes things a lot more difficult.

Just like Mad says. the valve has only one threaded hole
at the front to retain valve body in tube. (grip frame screw).
At the rear of the valve there is another hole (port hole)
the one you want enlarge to 1/4" and taper the
inside for best flow.
If you are going to do hot work why don't you just take
off the barrel and the drill out the transfer port hole
on the lower tube and the barrel and then
resolder ( or use new sm. i.d. barrel tube.)
Use a sm. brass/copper tube between barrel and
lower tube at the transfer port also.


Or if you decide to just drill through the lower tube
to enlarge transfer port make sure you add a bit of
solder at each side of body where transfer hole
is before you drill.

Below is a pic of a standard cartridge valve.
Post up a pic of yours if it is different.

If I were to decide to do a ground up build, how readily available are cartridge valves? I have done several projects with the old style valves, but these might make a new lower tube much easier.

As far as i know you can call crosman and order them brand new for like $16, make sure you order the 12 gram style ones.
