I was quoted about 400-500 dollars if I bring in my lathe bed, to have
it reground. The bed is relatively worn (carriage drops about 0.002 inch
near headstock), and the rest of the lathe is not.
I am ending my ebay selling soon, so I will have some more time.
If applying turcite and re-scraping the saddle is not too much, I will
have them do it too. My thinking is that after this, I will have a
lathe that is as good as a new one.
My current question is, how hard is it to take the headstock off this
clausing colchester master, and, no less important, how to align it
again once I get the bed casting back home.

0.002 isn't much for hobby use. Do the math. For a tool on centerline, how
much change
in diameter does a 0.002 drop produce?

Don't have an idea on that. Most lathe bed grindings I've read about are 2x the
price w/o
any fitting.

Well cutting a rod and measuring it will show if it is off as far as taper.
Loosen bolts
tap it in correcting direction and try again.
If you really have 0.002 wear, just use it as is.

Unfortunately, the inverted vee that holds the saddle, is also very
worn and so the saddle moves crosswise when I move it along the
lathe. I think that it is because the the vee wear. The difference in
diameter at various points is perhaps 0.2mm.

I do not like the latest ebay changes. I have way too much stuff to
sell, so I will be selling for a few months without buying anything
new.

I think that eBay is digging its own grave, by trying to become what
it could never be, and in the process, losing what it always has been
good at.

eBay could go back 5 or so years in time and be a fairly decent company again.
I don't care for ebay from the buyers side. Hiding bidding id's, that just
turned me off
100%.
