A New Trouble

[Joe And Penny Goss]

Hi Norm,
 By any chance is there a dag in that area hanging slightly on the key
stick? There could be a adjustment screw in the middle of the dag just under
the lip that needs to be turned out a tad. Also reset the cheek block on the
bass end so that the back of the action does not ride on the screw  under
normal use. It is there only for limiting the action moving in and out while
regulating. I found out the semihard way by following another tech and
having to solve the horrible squall the screw caused.

> I ran into a new one today. A brand new Henry F. Miller grand that
probably was not prepped at the store. I did ease all the keys as many
bushings were tight and quite a few balance hole tight as well. After all of
that, I still had a sticking key. It was C3, (3rd key from the top of the
bass), that would stick but only on occasion. It might play 30 to 50 times
normally, and then stick down with the hammer in check on the backcheck. I
then discovered that by slowly pressing the damper pedal, the hammer would
release from the backcheck and then with a little more movement of the
damper pedal, everything would drop back to normal. The hammer and the
backcheck look okay. I believe that the key end and the damper underlever
are somehow sticking but could find nothing out of the way like a burr or
something. The key does lift a spoon on the damper underlever and the felt
on the key and the spoon look very good. Looking for ideas.
