--Sounds like a fun project; I wonder if Snow Manufacturing is still
around? They used to sell modules to build stuff like this for the Big Guys;
some of it was really complex and quite innovative. Used to work for a
company that built custom automated manufacturing equipment and turning a
drillpress upside down or sideways is pretty ordinary. I have a vague
recollection of someone turning one upside down and mounting the base to a
ceiling rafter, then turning the head around so that quill pointed down
again. This allowed really huge pieces to be drilled anywhere on their
surface.
