Here's some quick sketches if anyone could make sense out of them (the
proportions are probably screwed up) -->
The press-

http://tinyurl.com/cz6avThis would be with wooden standoffs. There's also no foot cable shown.
I guess that would take an additional pulley or screw eye mounted to
the base or table to pull downward on the drill.
I'm sort of guessing that wooden holes in the holders would have an
acceptable amount of play (maybe a harder wood). I've used that to
spin a drum with just pine, for 1" pipe, and greased the holes. It
held up fine and even had to spin. I think with more than one screw
eye and cable attached to the upper quill part, it would keep too much
unbalanced pull from tilting the holders and screwing things up
(hopefully). An extra thick holder (laminated layers) might also help.
---- don't know?
