As others have said, there is a shelf life, but I seem to get a
couple of years out of a kit. Using more powder speeds the set up
time, and of course also makes a more putty-like mixture better
suited for working overhead. I've never had the problem with loss of
ultimate strength (from using too much powder) that Paul McCloud
mentioned, but I'll be cautious now that I've been warned! (thanks,
Paul). For stripped screws of any size I first paint or spray them
with Teflon as a mold release. Then I swab the hole liberally and
dip or roll the screw threads into the mixture before driving it
into place to the finished depth. Using a fairly thick mixture (as
for overhead lyre screws) I find that it sets up well enough in 10 -
20 minutes to remove the screws and use a sharp chisel to pare away
the ooze-out. If you do this before tuning the piano it will be set
up enough to install the lyre by the time you're done. <br>

Interesting you'd post this today. Last week I visited a Howard
grand whose lyre, well, needs some work. The single large screw
into the keybed simply spins and goes nowhere. I was planning to
repair it using T-nuts, but a product that can be used where CA
glue would not be effective would be good. It sounds as though you
use it a fair amount, right? How long has the small kit lasted for
you? How quickly does it set up, e.g. for the lyre, or for S&S
action brackets (I needed it for that on Monday!!)

add that the Lakewood is very handy stuff to have around. I
carry the small kit with me on my rounds, and have used it
in customer's homes for repairing stripped screw holes,
including stripped lyre screws. In fact, once I had to fill
large sections of the underside of a keybed where the lyre
had literally been torn out of the piano. You can mix it
thin, so it will be self-leveling or run down into small
hinge screw holes, or as a thick putty for working overhead,
as on lyre screws. It's my method of choice for repairing
stripped Steinway action bracket screws. It's not
inexpensive, and it reeks like bondo on steroids, but I I
wouldn't want to be without it.<br>
