Hopefully this page is OK with the OWW team. I have seen many machines where no one has spindles.

Firt Image :
(Group A) shows the two spindles that came with my machine. Using these as guidelines I turned my first spindle (C) using a 1" block of steel and inserted a bolt into this. Similar to the originals, but this spindle was not true. I wrote off using the 3" spindles from Delta for a while. I then considered turning down spindles that are available from Gizzly and Jet (F) but would have to remove the jam nut, and questioned its mass in my machine. I then turned another spindle similar to those I had in 1/2" steel to see what I could do with a 6" drum.(D) This drum was turned from a tooling plastic, and I cut some small rubber disks to compress and lock my sleeves in place. This worked, but was still out of round. My final Journey was finding the Delta set of spindles on an "auction site" for $40 new. I then took my 1/2" steel and turned a #1 MT on the end. Chucking this in my lathe instead of the 1" meant less material to take off and less time. This part was within .002" instead of the earlier models that were out .030" or more. A big Difference! Then using a shaft collar as my stop, and threading the end I was Done. The last one I made took about 2 hours total.
I used my existing spindle to gage a #1 taper on my cross slide. I then turned it. When done I sprayed the taper with layout fluid(Dykem) and twisted into my machine. This told me where I was not quite accurate in my turning. With a file and sandpaper, a worked until it was a tight fit and indicated within my .002" tolerance. I then set it up and threaded the ends.

Because these are from 1/2" stock A well equipped machine shop could do them fairly inexpensively with a tapering attachment.?? You could then do the sleeve and threads yourself.

Comments: Indicating for true rotation, this earlier spindle was out .020" this far down the shaft.
