Hello Clark,
If you cannot get new jacks I would suggest using
new Baldwin " regular " jacks. I have used them for
years. The "spiral "rep. spring fits perfectly into the
hole at the back of the Baldwin jack SCHAFF #
24541E
There is one addition you will have to make. The _K at B_ (mailto:K at B)
jack adjustment in the rep. window is at the bottom of the
whip. under the jack For a long time I would glue a wood
"tip" cut from a shank under the new jack..
However I found that it was easer to use screws, the
longer, ones from the brass seizure of upright dampers or
brass flange repair clips screwed in to a small hole drilled
into the bottom of jack. I also changed the wood adjustment
buttons on the whip to leather ( the old wood buttons tend
to break).
_K at B_ (mailto:K at B) action tendencies, The small sliding medal rods
that are used to change the hammer blow distance are bad
about squeaking I suggest you replace the leather.
Also they are prone to have a heavy touch I suggest you
install very light hammers no more than ten grams or less
at the # one hammer. On this action you can lower the
down weight from one to two grams by clipping the centers.
To the person who wanted a little back ground on this
Co. I will do some research tonight send something tomorrow.
Hope this helps-- Regards to all,
Jack Wyatt
Dallas
