Any tricks to freeing these bastuhds up?

TIA,

   I can't guarantee this but try heating the spindle and tapping on the
MT2 with the knock out bar.  You'll have to heat it quickly because the
drive center will try to heat and expand at the same time.  Don't heat
if very hot for very long because you could damage the bearing.
    Maybe someone else will have a better solution.  John Lucas

If it still doesnt come out, saturate the joint around the center with
penetrating oil, let it sit overnight, and try again.

If you ever get it out, cleanup and oil both tapers before using them again.

I hate to say it, but I have this same model, too.  Grizzly lied to me when
I bought this thing and told me that a knockout bar was available.  As you
have found out, it is not.  There is no place to knockout the MT2 drive
center.

Bad design made worse by a company that won't help at all.  I put mine in a
storage shed until I donate it to a local charity.  I went ahead and bought
a Jet.

As to getting the thing out, I finally used some pipe clamps and pulled
while my wife hit the drive center with a soft *** mallet.  Finally came
out, and the spindle was not damaged.

Get rid of this thing.

Put your penetrating oil on; blow some in the back end of the spindle, too.

Have the inboard end of the spindle covered with a heavy cloth or such to
catch/hold the center when it exits.

Hit the bar with sharp, straight blows with the hammer.  Go slow, working up to
the heaftier shot.  Don't use a maul or *** hammer, or anything like that
that will give less percussion. A two or three pound hammer is not out of the
question.  It's a *** operation; that's the way it is.

Same method is used to remove a self-holding taper arbor from an old style
milling machine that has been tightened with a draw bar.

[The alternative method, of course, is to set up some chatter on what your
turning, then the center comes walking right out when you don't want it to. ;)]

I was shown this trick many years ago and told to wait until the
penetrating oil started to bubble. While heating tap gently with a
hammer around the circumference.

There are possible dangers using this method, like having the bearings
dry out if you get it too hot, and I am sure there will be a storm of
protesting e-mails about the H&S aspects, but I have had to use this
trick on 2 or 3 occasions as a last resort.

The final choice is yours.

As a side note you can also use it to pull out small dents in car fenders
without damaging the paint by laying it right in the middle of the dent.
