Call me a crabby old ****, but I suspect that many of these basic
questions are for projects that never get beyond the "I was thinking
of..." and "how do I..." stage.

Not directed at the OP because he did have several clamps and you
probably wouldn't have several clamps unless you've actually built a
few things. Actually I'd say the number of clamps one has is probably
a good barometer of how much woodworking actually gets beyond that
"thinking of" stage... and that rusty pair of C-clamps on the shelf
don't count. Now... if those two rusty C-clamps are hanging on their
own nifty glued and screwed smartly labeled plywood clamp holder...
