Another day working on wheels (and so on).
Continuing from yesterday.
I built the rear wheel with an Araya small-diameter rim.
Campagnolo Record 8-speed freehub, 32H, fully Champion pattern lacing.
I'll do the wiring later.
Campagnolo's freehub first appeared as 8-speed,
and when it went to 9-speed they changed the spline shape on the freebody,
then made it compatible up to 12-speed after that.
So this freebody can only accept the original 8-speed sprockets from that era,
and since the spline shape differs from later versions,
you can't just change spacers and use 9-speed or later sprockets with it.
With current Shimano and Campagnolo freebodies,
the spline shapes differ in some ways,
so sprockets can only mount at a specific phase,
and the tooth profile is machined based on that positioning
to improve shifting.
But with Campagnolo 8-speed freebody sprockets,
the user has to do that work by hand (→here).
About the spokes—I said fully Champion lacing, but
the freewheel side uses 14-gauge plain spokes
and the non-freewheel side uses 15-gauge plain spokes
in left-right different-diameter lacing.
The nipples also alternate between 14-gauge and 15-gauge.
Since it's a single-wall rim,
when I shortened the spoke length by 1mm
it settled to pretty much flush between the spoke ends and the rim.
The images above alternate between non-freewheel and freewheel sides, and there's evidence proving it.
The nipples with round machining marks on their end face are the 15-gauge ones—that's how they're marked for identification.
