It's fair to say that all 240V equipment that doesn't also have 120V loads
doesn't need a neutral.

IME, big iron woodworking equipment consists, electrically, of a motor and a
switch.

240V motors don't need a neutral.

I am running a new circuit and would prefer to use 10/2 rather than 10/3;
but sure don't want to do it twice.

As long as 10ga wire, and a 30A breaker, are appropriate for the load, you're
good to go with 10/2 -- but consider that 10/3 would provide the ability to
add 120V receptacles later if you need them.

Another thought might be to pull three individual conductors (red, black, and
green) through conduit, instead of running cable. Then if you ever need a
neutral in the future, pull a white wire through too.
