1950 Delta Rockwell Unisaw Arbor Disassembly: Easier Said than Done!

In my what is now, to me, months long (by choice, no reason or desire to rush) into my 1950 Delta Rockwell Unisaw restoration project, I have watched countless other videos on EVERY aspect of this saw from repair to restoration. The goal of documenting my restoration process is to provide more in depth coverage of each specific topic than I've been able to come across. Of all the Unisaw restoration videos on YT, they kind of gloss over the aspects and or challenges of a particular part or process for whatever reason. I don't want to simply repeat what someone else has done, so my videos in this series will attempt to go deeper in covering each aspect of my restoration journey.
In this particular video disassembling the arbor is supposed to be a snap. Umm...WTF, why is my particular arbor giving me SUCH a headache in tryin to disassemble. One reason potentially is it's 74 year old age and the fact it looks like it's never been taken apart so EVERYTHING over the last 74 years has kind of "glued" (not really, but you get the idea) together over a combination of heat, usage and time.
So this is me scratching my head and trying to do what other seem to do in seconds on their video. My my experience(s) will help someone else. After all it's not the end result I enjoy (don't get me wrong, I do like the finished product) it's all the steps, hoops and everything in between that makes this a journey of ups and downs to get to the finish line.
Plus, most, if no all of the Unisaw videos on YT are OLD as heck! Breathing 2024 new life into the restoration of a great old machine.
This is an amazing machine truly built like a tank and I want to get it working and looking like it did the day it was built (or as close to that fact).
