My mistake. *Its a jacobs taper holding the chuck on the spindle. Had
a J/T M/T brain fartg

* * * * Most drill presses have both a MT (in the spindle) and a JT (at
the chuck end of the arbor), so both at the same time are possible.

* * * * However -- this looks very much like one which I saw at a
hamfest which had a Jacobs taper machined directly onto the end of the
spindle.

* * * * Except that the weight listed in the auction (about 100 lbs) is
much heavier than what I saw at the hamfest.

Can't find any markings on the keyless chuck. Probably screwed up
jaws?

* * * * Does the chuck look like the one shown in the last photo in the
auction you pointed to below? *If so -- runout is a way of life with
those. *The jaws are spaced by compression springs in holes drilled in
the meeting faces of the jaws. *It does not take long before one of the
springs gets warped, and forces two jaws farther apart, leaving an
off-center grip for the drill bit.

* * * * Also -- some of that sort are tightened by screwing onto a
threaded shaft -- but you could tell that by adjusting the chuck to
maximum size. *If you don't see threads above the chuck body, it is
likely a Jacobs taper -- and the pickle fork pairs are called into
service.

* * * * Anyway -- the suggestion of a loose qull in the headstock is
eliminated by the photos here -- this has the split headstock with the
clamp bolt to lock the quill at a given extension.

* * * The OD of the chuck seems to run fine & the spindle is not
loose. It appears this machine did not have much use.
Just so happens theres one ebay just like mine, only that ones black.

* * * * What color is yours? *Black was common for a *long* time.

* * * * Or is it possible that yours was repainted? *Check around the
edges of the badge on the front belt guard for traces of paint applied
after the badge was installed.

* * * * Sometimes, shops painted all of their tools the same color for
whatever reason.

Maybe older? Mine has a craftsman 1/3hp moter.

* * * * Maybe. *The motor shown here is a 1/3 HP one as well. *Pity that
the serial number is partially covered with grease, so you can't compare
them, assuming they are the same maker and model number. *The one shown
is certainly an old one.

* * * * Good Luck,
