1. The chuck is a force-fit onto a tapered spindle -- and the instruction
manual describes it as a "Morse Taper", not a JT!

If your machine has a female morse taper (which is very common), just dump
the current arbour and chuck, and replace both. The arbour should cost about
$10 or less. The chuck is the expensive part (which you had to buy anyway).
