You can do what I did - go to Google and type in Jacobs Tapers

As can be seen, its a #33

It's a 33. Just like the chart says. Pretty standard on smaller, inexpensive drills.

JBonez,
It is not unusual for a light-duty drill press to have a male Jacobs Taper on the end of the quill. I have a medium duty import (dare I mention that?) which has a 33JT quill.
When you buy the chuck with the Jacobs #33 taper, you should also buy the special pair of wedges that is used to remove these 33JT chucks. It's a pair of thin wedges with a U-shaped cutout that fit around the male taper.

Note that they come in sizes - you may have to research which size fits the 33JT.
You can get chucks on eBay.
