advice on action parts

[Jon Page]

In measuring S&S's, I found the KR to run between .52 to .54 and with
some  .56 to .58.  Some were .46 to .49.   But there is no evenness to it.

Would would imagine a  company of this caliber to produce a a closer
tolerance.  But then again, I wouldn't be getting all these actions to fix :-)
I have not needed to move the capstan often to the alter the KR.

I don't arbitrarily pick a KR, and then_make_it  work. I chose a KR to make
the
action regulate 'properly' (tounge in cheek) with the appropriate knuckle and
adjust weight from there.   The Renner Parts Kit is invaluable for this.
