  When I last needed to use a component with tab leads, which was a
coaxial power connector, I ended up using a hole large enough.  That
board went to volume; it really pissed off the assembly firm due to the
positional variation.  The part's tabs floated around within its three
holes quite a bit.  It was fine due to the wide tolerances in the
chassis the board mounted in, but the assembly guys didn't like it at all.
