Update:
Took mine apart this weekend and installed the Power Custom hammer and trigger kit.
First things...the cylinder throats measured with a ball mic are .452... call em plus/minus .0002
that's my repeat-ability window with this measurement method. BC gap is .0055 to .006 and
the cylinder "end shake" is .002. Did not check barrel choke yet.
The cylinder bore for the base pin looks like a small rodent ate it's way through, pretty
disgusting work. I've seen post hole diggers leave better wall finish. It's going to get
a light honing and one of the aftermarket .001 over size base pin.
The power custom hammer was sold as a "blued" hammer, it's not, just plain ole industrial
black oxide. Doesn't really matter to me as after I shoot it some more I'm sending it to
Turnbull for the CCH to match the frame. The hammer and trigger got rid of the creep the
stock trigger had. I clamped the gun ( gently with nylon blocks ) to my mill table and chucked
a dowel in the spindle, used the DRO to measure trigger travel. The stock trigger broke between
.115 up to .120 repeated several times. The Power custom ended up between .020 up to .023
again repeated several times. No trigger pull weight yet ( screwed up gauge).
Timing with the Power custom hammer and stock pawl was ok on 3 of 6 chambers,
instructions with trigger kit mentioned removing a bit off the second tooth of the pawl.
I left it alone as it was ok on 3 chambers and worked the cylinder instead as that's
where the inconsistency was.
This would be a good mod for a "shooter", if you're collecting maybe no so much.
With the half cock setup you will quickly develop a "turn ring" on that nice blued
cylinder.
Next up will be some hammer and trigger shims.....
