I restore old wood working tools, mostly to keep my sanity, but that's all I use in my garage shop. I acquired 5 old drill presses and am keeping an old (pre '45) Buffalo No. 15 and a Walker Turner. The Buffalo came with a Procunier tapping attachment but no chuck. I was thinking about a Jacobs 14N 1/2" chuck. The quill on this press is 1/2" in diameter. I've been trying to find out what the diameter of the hole in the 14N is but can't seem to locate any info. I've found lots with Morse Tapers on them, but this press does not use that type of attachment (see photo) Anyone out there know if these chucks came with just the opening and if that opening is 1/2"? I'm not sure if I'm attaching these files correctly.
