The Man Who Goes to the Past

I just received a comment saying "Congratulations on your 1st anniversary opening!"
I've been renting this storefront since July last year,
but it took 45 days (not business days, but literally forty-five days) to get a phone line installed,
so I was reminded that the opening got delayed.
Obviously, I couldn't sign a wholesale contract without a phone number.
But anyway, the official opening date is September 28th.

I'm thinking I'll build a "nomunLab 1st Anniversary Wheel" in commemoration of this.
Though it's already completely sold out.

I'm building the "nomunLab Wheel No.1 3-3-7," also known as a 63H wheel.
Drilling multiple holes in the outer part of this hub carries risk,
so I'm installing a second flange hole further inward.
I needed a large flange hub with no lightening holes,
and I selected one that met those requirements.

↑I'll make a guide like this. A tool born into existence for this purpose alone.

I use a punch to create indent marks that will serve as guides for the drill holes.

Drilling

Since I'll be using counter spokes, I add a countersink
so the spoke heads fit nicely.

From the inside, it looks like this

I also drill multiple holes on the rim side. Only the valve hole needs to avoid phase overlap,
so it's 32H × 2 for 64H, minus 1 for 63H.

From experience, I already knew that the seam on the XR300 rim
is slightly offset from directly opposite the valve hole.
So I can drill a hole here too.

The guide holes are drilled before expanding to the nipple size.
If I increase the holes on the rim's outer side (where the rim tape goes),
there could be strength issues,
so I pick up the nipples for the newly drilled holes
one by one with a magnet.

This is incredibly tedious. More tedious than the wheel building itself.

The finished wheel is (→here), but in this timeline,
an identical wheel has existed for about half a year already.
The reason is, half a year ago, I received this same wheel from myself half a year in the future.
Having two wheels that are completely identical (not just in spec, but in actual existence)
might cause a time paradox.
So I need to pass this wheel back to my past self.
And that's what I'm going to do.
