| The label on the front of the DP has two lines, one for Spindle and one
for
| capacity. The spindle line clearly says "JT#2-1/2" and the capacity line
| says "1/2 inch". Since there's a separate line for capacity, I saw no
| reason for them to have lied on the spindle line. BTW, this is an
| American-made machine produced in PA and I sincerely doubt there was any
| language problem.
|
| I found the four-page "Instruction Manual" for the DP and unfortunately it
| says nothing about the size of any component.
|
| BUT ... here's some interesting info from that manual that I had been
| unaware of:
|
| 1. The chuck is a force-fit onto a tapered spindle -- and the instruction
| manual describes it as a "Morse Taper", not a JT!
|
| 2. There's a nut that's threaded onto a cylindrical portion of the
spindle
| above the chuck and the manual says to hold the pulley while turning the
nut
| to force the chuck off the spindle.
|
| SO ... Let's assume that we don't know what the taper of the spindle
really
| is [i.e. it seems to be either Jacobs or Morse] and we're unsure of the
| "size". I'll try to get the chuck off the spindle this weekend and
measure
| it.
|
| Do you know of a chart for MT as well?

OOPS ! Sorry for asking before looking. I now see that the URL you
referenced has both JT & MT on it. Thanks much
