heavy touch.
    I'll be doing the usual ,i.e. easing tight balance rail holes , key =
bushings, polish and lube keypins , capstans, lube knuckles, rep levers, =
jacks , regulate----yada yada yada.

    My question is about these whippen assist springs-- I'm prepared to =
experiment and figure it out, but am wondering if anybody has some =
guidelines-tips for regulating these.
    Thanks and best wishes to all for a safe holiday.
