I Rebuilt Mercury's Rear Wheel

Wheels again today (and so on).

A customer brought in a rear wheel—an S3 model from a brand called Mercury.
The rim is from the same manufacturer as the Nomu Lab Wheel No. 2 and others,
and the hub is a Novatec 482SL with a branded name, so
it's the same as the Tni Evolite hub.

It's a tubular rim with a 30mm rim height,
and the rim width (for tubular, there's no inner width to speak of,
so the outer width is what matters) is 25mm—
still classifiable as a wide rim by today's standards,
but the serial number on the rim shows it was made in 2012,
so it was definitely a pretty wide rim when it left the factory.

It was laced all-black in a spoke pattern I call "comp-44,"
but the customer wanted it rebuilt a bit more tightly.

↑ Non-drive side outpoke
On the non-drive side, if I trim about 2mm off,
these spokes could serve as spares for the drive side,
so I carefully disassembled everything and returned them to the customer.
The inpoke and outpoke deform differently around the elbow.
If they were to be reused as drive-side spokes,
I think the original inpokes should go back as inpokes and the original outpokes as outpokes,
though using original outpokes as inpokes might be possible.
But doing it the other way around doesn't seem like a good idea.

You can go semi-comp without loosening the drive-side nipples,
but while I was disassembling the non-drive side,
sand had worked into the "periodontal pocket" of the nipples,
and I wanted to reduce friction between the nipples and rim anyway,
so I went full teardown.
Not because I'm treating this as another "wheels again (and so on)" job.
Definitely not.

Done lacing.

24-hole all-black semi-comp 46-spoke lacing pattern with crossed sections.
The original black aluminum nipples could be turned from the outside too,
and though they're not Squorx nipples,
their contact surface profile with the rim is quite similar,
which worked out nicely, so I reused them.
