I have a real problem with the 2MT shank, the shank will not release from the spindle, with the Clausing Mill it is "suggested" that one "gently" tap
on the Drawbar nut to release collets from the spindle. Well I am beating on a 3/8" brass rod in place of the drawbar with a 3 1/2# sledge hammer and the shank will not give.

I am building a tapered wedge that I will beat in between the spindle and shank and I have the pieces coming to make up a screw enabled device.
It has been suggested to heat up the spindle "very carefully", I have problems with the very carefully part.

Any suggestions on how to release the shank?

One has even said they had to disassemble the spindle and use a heavy press to get a stuck collett out.

You should have been able to simply loosen the draw bar a couple of turns then whit a good rap from your hammer the MT2 would have come loose
The 3/8" brass rod bothers me since the threads in the adapter is also 3/8"
If your draw bar is short or the threads do not engage at least 1 1/2 diameters it is too short.
Now here is one thing I would try before using a drift key. remove the washer from the draw bar screw it back in place all the way down until the head of the draw bar touches the top of the spindle then back it off 2 threads. If you have a pneumatic hammer put a blunt punch in it or cut one off until it is flat but one of these would be better

Then use that on top of the draw bar to free the taper.
I've used them on stuck items with tapers many times like tie rod ends where they were drawn up super tight and I could not get to the side to rap on the knuckle with a hammer and have almost never had an occasion where I couldn't free up what I was working on.
