Epoxy that I have found at HD is a
type of glue that you mix prior to application. Is that the stuff I'm
looking for?

All epoxies are two-part and most are mixed just before use. The exceptions are
the epoxies that cure by heat or UV light and can be premixed. You won't likely
find the latter in a retail store.

The stuff at HD is likely 5-minute epoxy or similar and tends to be cheap.
Getting small amounts of good quality epoxy is hard. One possible option is to
buy a West System's repair kit (about US$12) that comes with a couple of ounces
of epoxy, some fiberglass and some silica gel (Cabosil). They also (used to?)
sell a kit with several small packets of epoxy and nothing else - small foil
packets like the ketchup containers in fast food joints.

If this is a fancy, expensive piano and you want a really quality repair, the
better epoxy is worth it. If not, the HD stuff may suffice.

Also, someone recommended to mix it with saw dust to make it less
brittle or for some other good reason.

Epoxy will have the consistency of warm honey. Add some sawdust and it will be
more like a paste and can be easier to work with. Wood flour is better than
coarse sawdust. You should drill the epoxy before driving the screws - don't
assume it will expand and let the screw in.
