A customer brought in the rear wheel or what's left of it from a Racing Quattro LG.
All the spokes on the non-freewheel side are completely broken.
The bike got hit from behind, and
I didn't see it myself, but apparently the frame made it through unscathed.
This is rough.
I replaced the spokes and evened out the spoke-to-nipple threading depth across all seven locations.
Before installing the hub axle and building the wheel,
there's something that needs to be done first.

Of the seven rim holes on the freewheel side's outer section, positions 1–6 (excluding image 7 above)
show damage where the nipples struck the rim from inside due to spoke breakage shock,
causing burrs and chips to form.
I ground down and evened out all the protrusions that rim tape couldn't cover.
It's way out of true.
↑The amount of centering deviation at the initial build stage
From there, I tightened the non-freewheel side six full turns.
Up to this point, since I haven't trued it properly,
the amount of deviation varies somewhat depending on the position.
Once I'd roughly trued it radially and laterally,
I was hoping the rim would be just a sheet or two of paper toward the freewheel side,
but it came out centered. Oh well.
From here, fine-tuning the true could introduce more centering drift, creating extra work,
so I wanted to leave just a slight bit of room for tightening the non-freewheel side.
This time, I managed to finish truing without introducing any centering deviation.
Done.
All the spokes on the freewheel side came through fine,
and the rim showed no deformation in the brake zone.
↑The replaced spokes
The threaded end mostly came out in good shape,
but the head end had a lot of bending initially,
so I straightened those out to remove them from the flanges.
