Front and Rear Wheels Built with H PLUS SON Rims

I received front and rear wheels built with
H PLUS SON (Japanese aluminum rims) from a customer.

They requested an inspection.
Both front and rear hubs are Dura-Ace Track hubs,
and there's wear on the brake zone,
so these appear to be wheels for urban fixed gear or road training use.

Starting with the rear wheel.
32 hole, Sapim all-round leader #14 plain spokes
built in 6x6 JIS pattern.

The H PLUS SON marking on the rim
was readable right-side up on the right side.
Only the threaded portion on the right side of the hub's
small sprocket mounting seat was dirty,
so despite being a double-threaded hub,
it appeared only one side had been used.

The temporary centering was spot-on.
I cleaned the hub before work, but
I later thought if I'd left one threaded portion dirty,
I could've used it to distinguish left and right
in this photo.
Spoke tension was on the loose side, but
it was at a level I could respect—"this builder
has their own philosophy"—so
other than slightly increasing tension during lateral trueing,
I didn't consciously increase tension anywhere else.
Even after trueing, it remained perfectly centered.

Next, the front wheel.
Like the rear, it's 32 hole with all-round leader spokes
in 6x6 JIS pattern.

This one had center offset.
Lateral run-out was greater than the rear wheel.
Plus, spoke tension was even lower than the rear,
with nipples loose and tension lost,
resulting in one spoke rattling around,
so I needed to tighten even the lowest tension spokes
enough to prevent nipple loosening.

As a result, I tightened all the nipples,
then performed lateral trueing and centering.
The final tension ended up
the same as the rear wheel.
