Just keep in mind that if you're using drywall screws you are NOT
really cinching up your joint. Wood screws have a smooth shoulder on
the shank so all the bit is in the piece being attached "to" and the
piece being attached is chinched down. If you have threads the whole
length you aren't pulling the pieces together.
yeah, i understand that the dia. of the hole in the "shank" piece
needs to be a tad larger than the screw, and that the dia. of the hole
in the "pilot" pieces needs to be smaller than the screw. Using
drywall screws is probably not the smartest, maybe I should look at
other woodscrews w/ real shanks, but it always comes down to having
the "shank" hole all the way through the outer piece, and that is
going to vary based on the size of that piece. But drilling 1) pilot
2) shank, and 3) countersink is very time consuming even with 3
Just looking for "a better way".

modern cabinet assembly screws are what you want.
they have a head kinda like a drywall screw. they have a rolled knife
edge thread like a drywall screw, but the thread doesn't go all of the
way up to the head. the root diameter is the same for the full length,
though, so you only need one drill bit with the countersink on it.
the problem i see w/ this is the shank and pilot hole are the same
either the pilot will be too larger or the shank too small
the shank hole needs to be through the outer board and slightly larger
than the screw, while the pilot needs to be in the innner board and
smaller than the screw
I have owned many countersink units. What a mess. Most work, sort of. The
taper drill bits are nice but fragile and expensive. Carbon steel
countersinks are worthless. High speed steel much better but still a pain if
you drive a lot of screws. WE finally bought a set of Amana carbide
countersinks. They are available separately. The have two beefy carbide
wings, use a standard drill bit, have nicely machined bodies that match up
perfectly with the plug cutters (to make buttons) and last a long time. I
think they are around $20 but worth much more.
