There is no way you will get that welded and re machined for $65. Also my experiences with welding annoy castings has been unpleasant to say the least.

OK next problem.
I tried removing the facing cutter that's in it.
It seems to be stuck pretty hard. Isn't it just a matter of loosening the drawbar nut and giving it a whack with a hammer ?
That didn't work. The guy that sold it to me said he only used it for one task which was milling a face on something so this cutter prob hasn't been removed for years.
I don't know what the drawbar should look like but it's only threaded rod in there now.

Looks like a round column mill drill, so it will be either MT3 or R8, if so you need to give it one good hit with the quill locked and I'd use a piece of aluminum between
to save the threads on the draw bar.
As you said it's probably stuck over the years.Using Tapatalk

If it's stuck it's because its a Morse taper. You are probably going to need a significant shock to get it out.

I would probably take the drawbar all the way out, then make a close fitting drift and wail on that. The drawbar is probably bending and dissipating all the energy from your hammer blow.

I also made boxes for the rotary table, chucks and faceplates. Everything has lifting points so easy accessed by the crane hook.

Had to duck into town.
When I came back I used a bigger hammer and out it popped.
Another thing I found...The motor was mounted around 20mm too low so the belt wasn't lined up very good. I don't know why the guy left it like it.
So I lifted it up to where it should be. While fiddling with that is when I discovered the broken pulley. So part of that was of course the belt adjustment.
I reckon it will take me 20 mins every time I want to change speeds on this thing. It's a pain in the royal butt.

I have a vfd for my mill and motors to fit when I get around to it.
I just stay around the 4 speeds that doesn't need belt swapping.Using Tapatalk

Any chance of a pic of your motor adjustment please. It may be possible to fit one of several items to make speed changing quicker.
If the motor is mounted on a hinge type arrangement, a push type toggle lever could be fitted. If it's mounted on twin sliding bars, some sort of cam arrangement might be suitable.

Yep, here it is.
I was thinking of a couple of ideas myself, that I could do to it once I get it cleaned up and mounted on the stand. A couple of the free items it came with are lots of thick dirt and a kilo of sharp swarf.
It will need a big clean and lube. X and Y are hard to move and winding the head is near impossible. Once I get the machine freed up I'll seriously consider mounting some sort of motor drive for the head, just need to find a cheap DC motor with a worm drive larger than a windscreen wiper.
