Help me get this rotary table apart please

Is there a set screw in either of these two holes that might retain the worm screw shaft?

If so, it may be a double set screw... two in one hole, so if you remove one, check the hole to see if there is a second one.

There may be a dowel pin in one of those holes with a tapped hole in the end of it to pull it out instead of a set screw.

I believe you said you removed the collar from the bottom... did you also remove the 4 flathead screws and the round plate under them?

Edit: I went back and read your first post, I see you did remove the 4 screws...

Im not sure if theres anything in either of those holes. Oil pours out of at least one of them when I turn it vertical. I guess its a total loss oiling system. I am going to have a chance to mess with it tomorrow so I will report my findings.

SUCCESS!!! Thank you all for your input. So it turns out there were set screws in those two little holes. They actually are for adjusting the backlash in the worm. I took those out and it made the hand wheel a lot looser but I still couldn’t get it out and it was driving me nuts. Turns out there was a little collar under the large Allen that has a sleeve that retains the crank (circled in blue). I had to go under with a punch and pop it out then the crank came right out. The table came off just by using a dead blow and hammering on the bottom once the nut was off. Thanks again. I was able to take it all apart and clean the probably 50 year old oil and grease and rust inside and now I know that those set screws adjust the backlash and it’s smooth as silk now. Turns out after I got all the dirt and grime off that the table was made in 1966.

And the worm managed to be removed from the case
