I built it from the CVA kit in 1985. Since I signed up on THR a few weeks ago, and found this hangout to my liking, I decided to disassemble, clean and lube it, and try to find out on my own (no such success as yet) why the cylinder timing has never been good, although it has great lockup as the hammer is slowly drawn back, until it unlocks to allow the hand to advance the cylinder.
At full cock, lockup is such that the cylinder will not rotate counter-clockwise, but does not lock enough to prevent a little rotation clockwise, maybe 1/8" or so at the outer diameter of the cylinder.
From full-cock, and controlled release of the hammer, the cylinder sometimes rotates a bit counterclockwise, then clockwise to proper alignment, but NOT properly locked until just before the hammer should impact the cap... - and because of this, I have not yet fired the piece.
In preparation for the original assembly, I very lightly stoned burrs off the engagement surfaces on the sides of the bolt. I'm one of those "measure nineteen times - cut once" guys. This was with a very hard India stone. Fit of the bolt into the cylinder recesses is good - there's no "slop", and I'm happy with that.
I have thoroughly cleaned the frame and internal parts, and applied a thin coat of Ballistol.
Down to my questions -- I seem to have lost the CVA asssembly instructions, so I wondered - I ask that someone clue me as to the correctness of this assembly-
Should the bolt be installed before installing the hand/spring/hammer assembly, or should I place the hand and spring into hammer, and insert had in its' channel while positioning the hammer, and then install the hammer screw.
or is the bolt installed first, with its' screw ?
I hope this is clear.
Gotta run out for a few, and will check back in shortly.
I 'preciate it !
