Another day with wheels (details omitted).

A customer brought in a rear wheel built with a Reynolds 66 tubular rim.
Not a "66 rear wheel" but rather a "rear wheel built with a 66 rim".

The hub is a Tni wing hub, 20H all-black aero-lite 40-spoke pattern with non-drive side laced as radial spokes.
I don't know the history, but when I received it,
one spoke on the drive side and two spokes on the non-drive side were broken,
and while that definitely caused significant tension loss,
I can tell the wheel was already quite loose even before the spokes broke.
The customer wants me to rebuild this, but

the internal nipples are sometimes oriented correctly

and sometimes reversed.

These nipples have a deep pocket before the threads begin,
so when used backwards near the proper length like this

this side suddenly reaches the thread start, but
as you can see, the spoke threads aren't visible
(= the threads are almost completely used up)
so I can't make any further tension adjustments.
The three broken spokes were missing their nipples too,
so I needed to replace those,
and during the rebuild I found nipples with stripped threads,
so I replaced a considerable number with new ones.
A complete replacement might have been better.

Built.

20H black half-champion 4-spoke pattern.
I'll tie the spokes later.

As for rim weight, accounting for the difference between tubular and clincher,
it's about the same as the rim on my Nomu Lab Wheel No. 1.
The Nomu Lab Wheel No. 1 rim is 30mm tall, while this rim is 66mm tall, and
even if there were a 66mm tall aluminum rim,
it would be considerably heavier than around 460g,
so this rim has a pretty excellent height-to-weight ratio.
There are plenty of lighter rims out there,
but there aren't many that are this light at the same rim height.
The EDGE 1-68 tubular rim I have
(model 68 but 65mm tall) weighs 378g,
but EDGE rims from that era had a bizarrely good height-to-weight ratio regardless of rim height,
so comparing them would be unfair. ←then why mention it
