I am just wondering if someone has an approximate idea: how much does
a lathe rebuild (just a bed and cross slide regrind and Moglice)
cost.

Transportation of the machine is not a problem.

Sizes are 16x30 or 16x54 for the two lathes in question.

Wow! No idea at all. I'd sure like to hear how much I saved
by "doing it myself". On a machine this size, it may be more
practical to use a bedway grinder that attaches to the lathe and
runs a grinding head down the bed than to put it on a huge
surface grinder.

The question is labor cost. I rebuild for cheap cause I pay myself
nothing. Real easy to spend 200+ hours on something like this. If you
paid somebody 15-20 an hour, it could easy go over $10K. There's a
reason industry just scraps an old machine.

Karl, as you know, I trust and respect you, but I wonder why a rebuild
should involve 200 hours, if good equipment is available. I thought that
it is abous indicating and grinding the bed and cross slide, building
up with epoxy, and reassembling everything. I can see how it could
take a long time in the absence of a proper grinder etc. But would it
be time consuming to do myself. I personally would never undertake
such a project personally.

I have a friend that has a 10 ft stroke surface grinder and fresh paint
don't make them cut any more accurately.

if you're selling it, paint is the most cost effective thing you can
do. Especially a "taken apart" paint job. many folks know to shy away
from a quickie over the top painting.

I can only speak for myself. I've done a 10EE, a Hardinge CHNC, a
Mazak M4, an Excello 602, and I'm in the middle of a Matsuura
1000-VDC.

The huge time part is do to never having done that exact unit before,
and broken ****. There's a huge learning curve on this stuff. You end
up calling everywhere and/or fabricating items. For me, there is also
the Midas syndrome. While its apart you midas well to this, you midas
well do that, yada, yada.

My current project is in a different field, but the rule is holding.
I'm going to have 100 hours into rebuilding a Browning 1919
machinegun. I'm doing a second one, with all parts on hand this time,
and should knock it out in 15 hours. I got 1/2 way yesterday.

Well, I have done this the HARD way, without a grinding machine. So, that
part took WAY longer than it ought to, but I didn't want to assault my
back yard with any more heavy vehicles mired to the axles. The Moglice
job on the carriage should have been simple, but I tried to get by without
machining the carriage. There was too little wear there, so it ended
up too high, and I had to scrape the Moglice down quite a bit to get
the important stuff to line up. But, if I had had the bed ground on
proper equipment, it would not have been that big a job.

Oh, one trick I came up with to get it close was to rig the compound slide
to an angle bracket and put it on the bottom half of the tailstock.
I then mounted a toolpost grinder to the compound, and towed this rig
down the bed with a gearmotor and a cable. This did a really good job of
cleaning up the main bed ways, and I very likely could have just used the
lathe after this.
