tapping strings

What is it that you are hoping to achieve by tapping the strings? If
you've been reading on this list, it has been mentioned by many and
perhaps mostly by it's strongest proponent in Ron Nossman that tapping
strings produces mostly dents in the bridge cap but only a short term
effect in seating the string. If I understood correctly the main cause
of the string creeping up off the bridge top is the bridge pin climbing
up out of it's hole. I've seen this kind of thing in wood quite
frequently. If you open up the wall of an older home you will almost
always find the nails being somewhat proud of the wood. I believe that
the same thing is happening in the bridge and the pins need only to be
lightly tapped back in place. I personally think that this phenomenon
also occurs in the pin block too. I've seen older pianos where it seems
obvious that the pins were originally deeper in the block. I won't ever
drive them to the point where the coil is touching but if I find them
with the coil a considerable distance from the plate I will drive them
in some and retune. I hope this helps.
