Today is wheels again (and so on).
But before that, two things.
First point:
My Excel spoke calculation formula columns have exceeded 3,000 columns with this project.
It doesn't matter to anyone but me, but it's a milestone.
My spoke calculation formula uses one column per spoke length type.
So basically:
For wheels without an occho (normal front wheels or double-butted track hubs), one column,
For wheels with an occho (normal rear wheels or disc brake hub front wheels),
I end up using two columns.
For various nomlab wheels where I've memorized the spoke lengths by heart,
and for known hub + Open Pro rim, known rim + PowerTap G3 hub combinations,
I don't use the formula, so these wheels don't add new columns.
Next, point two.
The nomlab wheel 2.6 I built yesterday—
Before I reported that it was completed or
the customer saw it on this blog,
an acquaintance of the customer said to them "that's probably your wheel,"
and they told me this when I handed it over today.
I may have written too much identifying information about an identifiable wheel.
I wasn't scolded for it or anything, but
I'll be more careful going forward.
A customer who teaches English at a cram school
left two front wheels with me.
This front wheel has a White Industries H2 hub
and a ZTR Alpha 340 rim, and unusually it's 18-hole.
The ALPHA logo is a small sticker, so
this is an early model with thin holes on the inner circumference of the rim (therefore lighter weight).
Even if it's not an early model, whenever I'm asked to true this rim,
I have to stare hard at every hole in it.
The rim holes often have cracks in the front-to-back direction.
If I miss that and touch it anyway,
I can't rule out the possibility that I might have caused it to crack.
No problems this time, but the customer doesn't need the rim anyway.
Two spokes are missing, but I didn't ask how that happened,
so I don't know.
The other front wheel is a Colima Aero.
Since we're doing a two-for-one rebuild, this one is obviously also 18-hole.
Aero is not the generic term "aero rim"
but rather the product name "AERO."
Unrelated to this, but
the other day a customer was wearing
a really gorgeous Seiko leather strap dress watch (SARB065),
and when I asked "Is that a Presage?"
they said "It's mechanical."
I could tell at a glance that it was mechanical,
so I was trying to ask about grades like "Presage" or "Brightz,"
but I couldn't get our conversation to line up, and it turned out
"Mechanical" was the name of that grade.
It's my fault for not understanding immediately, but it's confusing.
The point is, don't give generic-noun-sounding product names.
The SARB065 has a 6R15 movement, not 4R series,
same as the higher-priced Brightz SDGM001,
and the dial is very similar too, so it's an incredibly good value model(shameless plug).
As for why the wheel is being rebuilt,
I assumed the customer simply wanted a White hub
and there was nothing wrong with the Colima hub, but
↑Yeesh...
W-wait, I need to change the subject.
Colima rims often have what I call "reverse rim" lacing on the holes, but this rim was a "normal rim."
The hole lacing is extreme, and the rim interior is filled with polyurethane foam (probably),
so the path the nipple takes is very limited.
It's actually impossible to build this rim with incorrect hole lacing.
So this rim definitely has correct hole lacing.
With 18-hole, that's 9 holes per side, so
unless you do something really twisted in your lacing,
radial lacing is the only option,
and with radial lacing you won't mess up right-drop left-drop during the rough build,
so as long as you pay attention to the hole lacing you're fine.
Built.
The Colima's original spokes were CX, and since the hub flange isn't "through" but "hook" type,
flat aero spokes could be used.
If I'd machined these CX spokes with a spoke cutter, I probably could have gotten
the length needed for building with an H2 hub, but CX spokes don't fit through the H2 hub.
The ZTR wheel's original spokes were CX-RAY, but
to reuse these and machine them for the Aero rim with an H2 hub
would mean they're too different in length.
In other words, no matter what, I couldn't reuse the spokes.
So it ended up being 18-hole new CX-RAY counterclockwise radial lacing.
