Is this a jacobs J3 or J33 tapter or a Morse taper 2,3,4, etc? Easy answer
finding exercise... Is there a slot to drive a drift into th force the
taper out of the spindle? If so, it's a morse taper.
Now... Even if it is a morse taper, the chuck may mount to the jacobs taper
on the end of the morse. When the chuck falls out, does it have a tang on
the back or an open hole which mates to a small taper? If it has a hole,
it's a jacobs taper.
If the taper has a burr, lightly run a flat file over the burr. Make sure
you don't file the taper... just the burr.
For either, wipe them down with rubbing alc. or acetone. Put it on by hand
and retract the chuck jaws into the chuck (most are best this way, some are
better out... but hardly a few...)
Get a heavy hammer and a piece of 2X4... Place the 2X squarely on the end
of the chuck and wack firmly up. It may be easier to lay the drill press
over and swing sideways...
eMail me privately and I'll send you a "manual" we provide to our customers
who need to do this...
