I recently bought a mortising attachment and a drill press. The
installation of the attachment is very straight-forward. Everything
seems to fit well. The problem that I've encountered is that when I
start it up and begin to "drill" my mortise, the spindle & chuck fall
out. The spindle has a morse taper on it. The only thing that I can
figure is that the wood pulls on the chisel and/or the auger bit and
jerks the spindle out. After it happened the first time, I took it
all apart and "re-installed" the spindle by placing a piece of wood
under the chuck and forcing it to "lock". Right after I started
drilling again, it did it again.
Any suggestions?
Thanks,

BAD...leave the R12 where it is...we have enough global warming here in Nooo
Yawk (was almost sweating on the train platform this morning with the
33'F...a heat wave compared to the last 6 months).
As for the cabinet door, that is an easy fix. Get the brad nailer. But
remember this...this is no more important safety rule than to wear safety
glasses.
The posts that follow are twilight zone...if true about the demise of R12,
then scary...read on (if you have enough light from your $5 shop lights that
is...LOL)

Heat up your chuck in an oven before 'whacking' it back on. ( About 250'
F. ) Re oil after it cools.

I have had this problem.
I traced it to a misalignment in the setup that meant that there was a
sideways thrust on the chuck.
My drill, adequate for most purposes, is an imported Twaiwanese (I think)
where the machining is of indifferent quality. The quality of the fit
between the arbor and quill is less than it could be, so the chuck falls
out.
Drilling machines are not designed to take any sideways thrusts, though on
the better machines people get away with using sanding bobbins and certain
milling cutters.
Proper milling machines are fitted with a drawbar that screws into the end
of the arbor and passes through the length of the quill.

The real story on the R-12 deal is that Dupont's patent on R-12 ran out and
everybody was making it. Too much competition if you will. They invented
the later version and lobbied for R-12 to be banned.
As for an answer to you ozone hole question, IIRC Switzerland had been
monitoring the ozone hole as far back as the 20's and found it to be just as
big as it is or was when R-12 was banned. It does apparently open and close
as mother nature finds necessary.
Stay tuned for the sequel. The R-22 patent will expire shortly.
I never cease to be amazed at how easy it is for well funded companies
to place the proverbial ring through the nose of Congress.

Go back to the NASA Antarctic Territory studies of 1957, the enlarging of
the ozone hole was noted and explained as a side effect of the "wobble" of
the earth.
Proponents of banning chlorofluorocarbons took their measurements at maximum
"wobble", which showed a larger hole.
The patent on the popular propellant ran out in 1997. The patent was worth a
fortune and there was only one suitable alternative propellant. The patent
for the alternative was held by the same company.
Guess who is rumoured to have indirectly funded the green push to ban the
(patent expiring) propellant - the same company.

make sure there is NO oil residue on the mating parts and of
course that it is spotless clean. then give it a good
couple of whacks. same thing happened to my Delta. a bit
more force and a clean taper took care of it.
if you have lacquer thinner, you could clean with that,
being careful of course to keep it off painted parts. :)

Hey, I might not have sprung $33 for the deLUXE version but
I dropped $20 the 4 footers. Besides, there's 11 lights in
my shop, plus some task lighting for good measure! :)
33 degrees? we break out the mittens and long johns if it
gets that cold here! :) Today was around 70, which is
pretty typical for us this time of year.

I used to buy it 100 cases at a time for 99c per can in the
80's. Sometimes the local Kragens would have it cheaper but
do you think they wanted to sell their loss leader to a
shop, in bulk?? NOT! :) I'd be lucky if they'd give up 10
cases at their sale price.
and a can wasn't a lb. it was just 14 oz by then.

I saw a swirling blue miasma over San Jose today. Was that
the hole in the ozone layer, Tom? I'll open an couple of
cans of my R12 and see if it grows.

I've got a cabinet door that does that, but I think it's
because the cabinet is overstuffed.

Jeff...you're right in that the misalignment is the "final straw" but the
problem goes back to an earlier post. The chucks on the far-east machines
have a tendency to fall off even when drilling. Clean them up good (acetone
or denatured alcohol and a little fine grain wet/dry on the spindle for good
measure) and then re-seat. I have two Delta's and it only took one or two
attempts on each before the problem went away forever. Whether designed for
it or not (if not then Delta and Jet should quit selling them!), the drill
press can handle some side-play.
All that said, I gave my drill-press attachment away several years ago and
got the relatively inexpensive dedicated machine(couple hundred $US but it
came with 4 bit/chisels that are fine for my rather modest expectations...at
the time Delta was almost giving the attachment away but making their money
on the bits...kinda like Gillette with Mach whatever they are up to now). I
found that the set-up on the attachment was a PITA and it was not very
accurate due to more flex in the DP vs the dovetailed way on the mortiser.
Plus every time I got the DP set-up with the attachment, it seemed I needed
it for what it was made for.
