skou — I’ll give that a shot. Will 3-in-1 oil serve the purpose?
3-in-1 oil is better than nothing, but real penetrating oil works better at freeing rusty joints. Something like Liquid Wrench or PB Blaster. Any auto-parts store will have some.

To expand on what Terry said. Cut two wooded wedges, with a slot in the middle to fit around the arbor. Place one on each side and tap the left one in, then the right one. Trying to keep em both somewhat even. Seeing if ya get any movement. Ya might want to put something across the way tubes to catch the chuck in case it suddenly pops off.

I think the word really should be galling.

Another prying option would be a tie rod separator

Just make sure the one you use will clear the spindle. Most will.

Okay… (sorta)
The oil and a couple of wrenches got the chuck turning on the spindle but it moved no further from the collar.
After a few minutes I noticed what looked suspiciously like a rust coloring gathering in the oil visible in the set screw hole. I turned the stock to the vertical position hoping this will help the oil work its way between the sections where the spindle and chuck are caressing one another. Devoted to one another though they may be, their relationship must come to an end. It’s alright with me if they remain friends, but marriage is out of the question.
As suggested by beeg, I’ll slosh in a little more oil, wait a couple hours and take a look to see what gives. if needed I’ll use a blunted wood shim and a rubber mallet to see if the chuck can be moved away from the collar.
Thanks folks.

You said you were able to turn the chuck some. This is a good sign. Now, patience must become you friend. If you get over zealous, you'll get it jammed on real good. Try turning it back the other way and then back and forth while keeping it oiled up with something like PB Blaster.
You'll be amazed when you discover just how small the object is that has it stuck.
On a machine that has not bee used and abused, that chuck will suck air when you pull it off the shaft. It is closely machined to the size of the shaft.

What wood you people think about using evaporust or CLR in place of a penetrating oil?

’lo dusty,
The chuck is rotating on the spindle easily in both directions.
For now, it’s oiled up better than an overworked pole dancer.
I’ll check it again in a few hours.

’lo dusty,
The chuck is rotating on the spindle easily in both directions. Just need to get it to free itself of the spindle altogether.

If it spins (rotates) easily on the shaft but is hard to pull off, I doubt that oiling it is going to help anymore. It is now time to overcome the burr (or whatever) that is preventing its' easy removal.
Time for the wedges and rubber mallet OR (something I've never heard suggested here) a bearing puller like device. Like maybe a bearing puller.
Using the chuck key, can you open the chuck so that you can see the end of the shaft?
