Shouldn't be too hard as forstners run on their rim. Sequence of events would be as follows. Take one of the short arms and press the bearing in half way. Take a 7/8 forstner and drill it about a quarter into the plywood drill press table. Flip the arm and use the bearing to locate the arm for the bearing hole on the flip side. Drill for the bearing (you've previously set the depth.) Take the arm off the drill press, drive the press fit bearing the rest of the way. Drop the bearing in the flip side. Done.
I've got bigger problems though. CNC guy at work doesn't want to spend the time locating all of your .dxf files on the plywood and programming the machine. So, I might be back to just cutting the whole thing out anyway....
Sigh, Charles
