Action modification results.

Jon,



When you move the stack are you not changing the strike position?   I'm missing something here, probably...I'm assuming you moved the stack towards the balance rail...how do you compensate for changed strike position?

The old knuckles came out easily and I cut the slot further out and used a shim

alongside the core on reinstalling.





The KR is .51, moving the capstans forwards was considered (since they were

on the rear portion of the cushion) but I opted for stack relocation which corrected

the strike line.   The stack was not placed properly at the factory, go figure.





I'm finding quite a few mis-located stacks even on famous makers.
