Why would spoke tensions be uneven, despite equal thread engagement?
I can think of a few causes related to the parts and material:
Manufacturing tolerance of the spokes. They are not exactly equal length.
Manufacturing tolernace of the nipples. I assume they are ...

Is replacing single spokes by a different spoke type harmful?
Intuitively, it seems like different spokes might respond differently to identical tensions and cause a wheel to be more "volatile", so to speak. So, a wheel with straight-gauge spokes with ...

Is replacing single spokes by a different spoke type harmful?
"Conventional" spoke is a term that can use more specificity. What matters for the purpose of having a wheel that you're less likely to be stranded with is whether it's built with a hub and ...

Mavic Helium clincher wheels: Replacement Spokes
I think that the Helium was one of the first pre-built wheels. By now, it seems that most of the industry has moved to selling complete wheels, whereas in the day of the Helium, you'd probably talk to ...

Why would spoke tensions be uneven, despite equal thread engagement?
Manufacturing tolerances is my best guess. The rim is not a perfect theoretical circle, its wall's thickness is not perfectly even all the way around, spoke holes are not drilled perfectly identical, ...

Spoke washers needed for Sapim Strong spokes?
Hard to say.
The spokes in the images are not tensioned very much because I see a pronounced curve in both. The spoke J bend has not been seated by spoke tension, nor has it been tapped with a hammer....

Wheel centred in frame but dished 8mm to non drive side, why is this happening?
Let's talk about the wheel alone first. If you measured the distance to the stack of coins to be 8mm, then the wheel is out of dish by 4mm, i.e 4mm away from the center line. In other words, you would ...

How to replace a broken front hub on a vintage steel wheel from a vintage steel bike?
Just to say that I rebuilt the wheel very successfully and easily while watching a movie one evening.

Mavic Helium clincher wheels: Replacement Spokes
With the old Helium, the rim is not so unusual in that there's a relatively standard nipple in a double eyelet.

Is replacing single spokes by a different spoke type harmful?
Since all spokes are made from only one type of material (steel), the only thing that matters here is cross section. A steel wire with a certain cross section has a certain spring constant.

Spoke tension of the lower-tension side?
Anything above 750N on the lower tension side is fine. Just make sure there are no individual spokes with lower tension.
You can’t do much about it anyway. You pretty much have to take what you get ...

Looking to understand the math behind spoke length calculation. Help?
I can't speak to the maths side of it so replying here. Also, too long for comment, and images.
