There exist automatic wheel spoking machines, typically used for mass produced bikes. If I buy a new bike the first thing I do is check the spoke tension because for sure it will be a huge mess. The next is to check the fork bearings because those will usually be too tight (you can feel the individual balls) or too loose (a clicking sound when you hold the front brake and rock the bike back and forth). The joke here is that when you buy a bike it's more work than building one yourself because you first have to take it apart again. That's obviously not true but I've seen some pretty bad stuff come out of factories (brand names too...).

One recent weird thing on a brand new bike was a set of spokes that had the inside and the outside exchanged leading to all of the spokes rubbing gaps in each other. I still wonder what the story was about that one, it makes absolutely no sense at all that an error like that would be made in a mass produced bike and no sane bike mechanic would spoke a wheel like that.

I've seen videos of wheel making "by machine." There is still some manual work, such as part or even all of lacing. If a wheel is laced "off," then it's pretty much downhill from there.

By day I'm an industrial physicist, and I've designed systems for doing automated mechanical adjustment. There's an 80/20 rule, where tightening the specs can dramatically increase the cycle time. So, you can make more widgets per hour if you relax the specs.

I remember taking a bike maintenance class where the instructor said that mechanical wheelbuilding has not reached the level of quality of hand wheelbuilding (maybe he even said "has not approached").

Since this part of the thread is kind of about that question, I would like to ask: how come? Isn't machines' consistency something that could be very useful here? And if not, couldn't tools like the one presented by the original post help the machines reach a high standard?
