Yes, Leon, those are the exact same "models" that I have. I've posted my
scan of the "manual" in the dropbox at
http://www.metalworking.com
and the measurements I made in the accompanying text file.
Yes, it certainly appears to be a JT6. Knowing that, I searched Enco
http://www.use-enco.com
for JT6 chucks and came up with 4 ranging from $18 to $84 at
http://www.use-enco.com/CGI/INLMK32?PARTPG=INSRAR2
so there may be new chucks available after all.
Thanks very much for the info
Hi Norm,
Is you're press badged as made in Taiwan too (now that you
know where to look)? I don't think mine are quite as old as
yours, probably bought in the mid to late 70's. They are
subtly different too. The slightly newer one doesn't have
the nut for removing the chuck, nor any threads for one. The
manual that came with that press still pictures it in the
parts diagram/list though. Instructions for removing the
chuck still tell you to turn the non-existent nut too. This
is also the manual that calls it a Jacobs taper. Just
eyeballing them though it appears to be the same taper. I
only popped off the chuck on the press that has a threaded
nut :)
You might want to check how much play there is when you run
the quill down and inch or two. As I mentioned, mine are
really loose. I don't know what the other readers opinions
are, but for drilling tiny holes I don't think this would be
a good thing.
