[CAUT] tight balancier

[RicB]

Hi all

I'm not quite sure I follow this either. All other things being equal, 
jack rest position just changes jack travel and timing.  It will end up 
in the same position at full keystroke however... for that matter from 
the moment the tail engages things will be equal in both cases from that 
point onwards.

This said... Skolnik covers a lot of good ground on this thread in a 
short space.  Wims problem .... Wim, seems to me you have more or less 
eliminated the balancier centerpin tightness and the repetition tension 
from the field of potential sources of your problem.  Strikes me as time 
to look for other sources. David listed up quite a few classics.

Cheers

    jack top, or the back radius of the knuckle will rub or otherwise

    I don't know that I understand this.  I believe that the jack
    position at
    rest, if moved farther under the knuckle, will simply cause the jack
    to begin
    moving earlier in the keystroke, (for a given let-off).  Once the
    jack is off the
    spoon, it doesn't matter where it started.
        It is helpful to place the action in check, then adjust the
    capstan so
    that the jack is equidistant between the knuckle and the stop pad. 
    This is your
    optimum blow distance for that particular let-off and dip.  Changing
    the
    beginning jack position won't have any effect on this.
