Well it's reasonably clear that economics are a prime factor. I'm not
planning on paying much for my swap/trainer wheel. I don't have a
spare lying around but I might go second hand shopping for an old used
wheel somewhere. I found an 8 speed campy wheel/hub for around 30$ but
I assume that's not compatible.

That's correct.

I too can report that Shimano 9s cassettes shift fine with C10
systems, you just need to set the first position on the small cog, and
set the limit screws to lock out the last click.

Personally, I'd stick with 10s chain, as the RD cage plates on a 10s
are closer together. I used a 10s RD on an otherwise 9s system, and
the chain was noisy enough going through the pulleys to make me
worried stuff was scraping. 10s chain quieted it right up, and I wound
up switching to 10s on that bike soon, anyway.

Is it possible to discard a cog and make a workable wheel by using 9
speed or 10 speed cogs on the 8 speed hub ?
In other words, can I convert an 8 speed wheel to work with a 10 speed
setup (at the price of sacrificing some gears)?

It's good to know that shimano 9sp works as well, that broadens my
second hands buy criteria.- Hide quoted text -

Not on a Campy 8-speed hub - those have a different spline pattern
than the 9/10 ones. On Shimano, 8/9/10 speed hubs are all the same
thing (well, there are some 10-speed-only hubs, but that's a different
story).

So your cheapest option is to get any 8/9/10 spaced Shimano wheel and
get a 9-speed Shimano or SRAM cassette, adjust your limit screws and
cable, and go ride.

FWIW, the SRAM PG-950 12-25 cassette I had on an Ultegra 6500 hub
shifted better than the American Classic 12-2510-speed conversion
cassette I got to replace it, with an otherwise 2007 Veloce 10s setup
(including chain). I just didn't have an 18t cog on the SRAM, and I
can't say I noticed.

If you have an additional 8sp cog in the proper range, you can respace
the cassette and get 9 cogs x Shimano spaced on. I think that the
Campy 8sp cogs are 1.9 mm. If you use Campy 10sp x 2.4 mm spacers you
come up to 4.3, which is Shimano 9sp and 10 sp Campy shifters will
shift that.

I haven't done this. I would try 2.0 freewheel spacers with the 1.9
cogs. You'd need an additional spacer ~1 mm before putting on cogs.
That would bring you up to 3.9 mm, Shimano 10 spacing. I regularly
use an older Campy 8sp rear derailleur and that shifts 3.9 aOK.

That's a good idea, I might just respace that. I just checked out what
a new setup would cost me at my bike shop. About 95$ for campy Khamsim
set (promo) + 30$ for a Tacx training tire + 50$ for a 10sp cassette.
That totals at 175$ just for a trainer-swap wheel, a bit over the top
if you ask me.
