No prob.  I was actually pretty impressed that they managed to accomplish
electrically moving the table without any belts.  I'm certain that given the
correct gear ratio in the motor, a "direct drive" solution as they've
illustrated would be far better for you.  Don't know what kind of "torque"
you'ld get out of an old windshield wiper motor, but perhaps that's an
option.  The one problem I can forsee with the setup in the picture is if
the table becomes warped or deformed slightly.  The rubber wheel they're
using in the picture may have to be a bit thicker to compensate for minor
surface irregularities.
