probably send the arbor to have it checked and have the bearings
replaced.

This isn't a difficult job to do yourself. Replace the bearings
(http://www.ntnamerica.com/Engineerin...0/brghndlg.pdf has some
dos and don'ts). There should be a wave spring (like a thin bent
washer) pressing against one of the bearings. If it's not there, make
sure to replace it since it preloads the bearings and reduces play in
the arbor.

Put the arbor back together and get a dial indicator and magnetic base
(cheap and handy for other jobs). (1) Put the indicator on the shaft,
spin it and find the maximum difference in plus and minus readings
(the runout). (2) Put the indicator on the flange and repeat. (3)
Shake the shaft in each direction to check for play. With any luck,
you'll have less than 0.002" in each test. If not, it's time to
double check the bearings were assembled correctly then replace the
arbor shaft or find a machine shop that can repair the arbor.

I wasn't able to check the table for flatness, but it wasn't obviously
warped. But it has a chunk of iron missing where the right extension

You can find a welder and have the existing table repaired by welding
up with high-nickel rod. This leaves a silvery spot on the grey cast
iron, but it sounds like the two problem areas will not be visible
after the saw is assembled.

The motor is a three-phase motor, and it's the old style, of course. I

This would make me want to pass unless I could negotiate a big
discount -- It'll be easier to find a complete single phase saw than
just an old-style single phase motor. Lots of single phase hobbyists
repowering old three phase industrial machines. No industrial users
repowering old homeowner saws.

As you say, you could use a modern motor ($250? plus starter) and cut
the cabinet, but then, what's the point of rebuilding this old
machine?

Does anyone have a cast Delta table, motor cover, or old-style

A motor cover just went on ebay for $238:

If you just wanted something solid to cut wood, this could be a good
purchase. But given that you want a restored, complete machine, add
in the cost for the missing parts and contracted work needed.
(Perhaps something for your time, too.) I'll bet that total will be
more than a more complete, single phase machine.

Good luck with it.
