First lets focus on getting that turret out. The 3k can be complex if you haven't dealt with it before, so I'll walk you through disassembling some of the internals so we can get our hands on that turret. Unscrew the screws circled in red. Ignore what's circled in green. I had already started the mod before I decided disassembly pictures were necessary.
Now remove the valve and turret assembly. Removing the pin in the orange bar and the valve pin from under the claw piece helps to get the assembly out as you jiggle it around.
Once you remove the assembly, unscrew the screw circled in red.
This is what should all fall of without any force (minus the screwdriver of course!).
The piece circled in red showuld remain on the turret rod. Just pull it off, you may have to apply a bit of force.
Tug the pin circled green out as shown.
Now just pull out the turret.
Now to widen the turret holes. The stock holes:
Drilled out (not sure of the size of the bit I used, but I think it was a bit smaller than the 3/8" bit I have):
Clean up the holes with a knife and sandpaper.
Now to improve the seal. Cut some 1/2" brass to the length of the valve stem.
Now glue it over the stem.
Cut some 17/32" brass to the same length.
Now get an old credit card or someting similar and and trace a circle onto it (if using a thin tip sharpie trace 19/32" or 5/8" brass, if using thick tip sharpie then 17/32" brass will work).
Drill a hole in the middle of the circle with the drill bit you used to widen the turret holes. I used a nail to make a pilot hole so I could get the real hole as centered as possible.
