Stability concerns

Hi all,

I have had a chance to do some *interesting* comparisons recently.

The contest:

Tightening tuning pin coils VS tapping strings down on the bridge.

Results so far:

Attempt #1 coils then bridge

tuning pins pitch drop between 21-118 cents
setting strings pitch drop between 18-69 cents.

I hope to try the reverse order very soon on an instrument.

It seems so far that coil setting is *more* important than setting the
strings on the bridge--but that setting the strings lowers the pitch more
*evenly*.

I have done the coils on one instrument *after* another tech had set the
strings on the bridge. Piano was between 3 and 18 cents flat before coil
tightening. After the proceedure pitch was 37 to 133 cents flat!
