Here's a pic of one of the bulkheads off the drill press, but not yet finished. I ran the drill down the hinge pin hole, and used it to remove a bit from the remaining outside. I still need to remove the rest of that material (by dremel and by hand) as well as do a bit of shaping on the inside to give the arms full range of movement. You can see I left the center section in place.
Its pretty shiny, so the contrast is a bit tough to see. :)
