The "hex key" chuck on my "new" Homecraft 11-110 drill press is pretty simple, in terms of how many separate parts and ease of disassembly. Simply unscrew the outer sleeve and the parts seen below just drop free. The only remaining pieces to the chuck are the main body and the cam in the main body used for final tightening. A very simple chuck. Oh, and notice how nicely the drill press table turned out after cleaning it. I scraped off the heavy rust, then took 320 grit sandpaper and WD-40 to it. See the last blog entry for a "before" view of the table.
