It is highly unlikely that any of us here are involved in manufacturing. Relatively few of the organizations listed at bikecolectives.org even repair bikes for customers.
Most community bicycle shops assist the general public by either giving away repaired bikes that they were donated for free, or by helping people in their local communities learn or practice bike repair. Even some of the larger operations I've visited (Portland, Philadelphia) seem to operate for-profit repair and sales as peripheral functions. We are not normal bike shops (LBS) for the most part, Christopher.
I'm entirely interested in sophisticating my technique; at our shop we strive to communicate correct (or relatively correct) techniques for each process and even if the "perfect" method cannot be imparted for whatever reason, it's always good to have that knowledge in my back pocket to calibrate my general understanding of processes, materials, and engineering.
This being said, 90% of what we do involves helping a drunk homeless person fix a flat tire or repack a wheel hub, or a ten year old and their parent fix up an entire bike that's been sitting in their backyard for two years when they have /exactly/ one hour to spend. Or refurbishing the center pull caliper brakes on a college student's bike they inherited from the previous tenant at their apartment, when that college student has very limited interest in the process, being that they are a freshman just having arrived in town from another country, or they are nerve-wracked over finishing their thesis. Sometimes there are gangs of neighborhood hoodlums who probably stolen some or all of the bikes they've brought in, and barely care at all about anything other than "make it go". Having a scientifically proven method for calculating microscopic stretch in a stainless spoke is basically psychologically and practically irrelevant to all of the above populations. And it is irrelevant to our bottom line as an organization. We help people, we provide a welcoming and safe space, and we triage worst case mechanical scenarios.
We on this list work with people as much as bikes, and you can't Six Sigma social work because you can't Six Sigma human life.
Also, I find it odd that as a frothing evangelist of precision methodology, you can't seem to figure out how to properly reply inline, create paragraphs, or orient yourself among a variety of threads. Those are some pretty basic and important skills when interacting with a mailing list.
I don't disparage your salesmanship, and certainly if you have valuable skills, you should be able to get compensation for employing them. But we aren't your employers, and a mailing list is not an acceptable place to sell anything. You might notice that you are the only one who ever appears here to do so. If you want to verify that, you can search here: http://lists.bikecollectives.org/pipermail/thethinktank-bikecollectives.org/
We all come here to maintain and develop community, to ask and answer questions, and generally to share information. Please do conversationally share tips and techniques here, if they're real someone will benefit from such. Please don't, however, try to sell anything, evangelize, or spread hyperbole. Nobody here has time for that. And a gathering place for largely nonprofit programs is a terrible place to sell things. Many of us have a hard time just keeping the heat bills paid (if we even have heat at all).

So, in the question of wheel truing, I am wondering why you don't allow for rims becoming deformed. As a learned mechanic you know of the procedures Barnett has for unbending a rim, or you know how to replace a rim or even sell a customer an undamaged wheel to replace the damaged one. Unless you promote that a damage wheel will be just as safe for the cyclist to use as one that is not damaged. As a mechanic: when you sign off that the work is compleated your actions say that the bike is up to standards and safe.A court of law does not recognize ( as safe as it can be) as a legal defination. On your own bike you can work on a bent wheel, On a customers bike, you take on a world of liability if you do not complete a repair to the safest standard, The action of presenting damaged product as safe can harm both you and your business, Your presentation implies that rims maintain perfection except in cases where spoke tension temporarily interferes.
In other words, it's obvious that while some spokes may become loose through repetitive stress, since the web of spokes share a single load, others will become tighter as the rim deforms. Since little can be done in the average shop to re-perfect the bare rim once deformed, the tighter spokes must maintain some amount of increased tension to keep this now-deformed rim true.
I'm not going to present any test that I've developed to "prove" this process, I'm actually posting this response because I find it kind of offensive that you keep posting here essentially as a salesperson. When someone posts to a mailing list to sell a product, to me that constitutes cause to block that person from the mailing list.
If you want to freely share here tutorials and techniques for everyone to review and learn from, in the interest of helping community bike shops hone their skillsets to a higher standard, I'd be the first to get interested. As it is, you never post detailed instructions, and quite frankly a lot of the processes you allude to are bizarrely out of scope with what most of us do on a daily basis. Do you ever tighten a bolt too tightly or without enough clamping force because you do not measure torque? If a bolt broke or slipped would you be liable? Do you like feeling grind in your hubs or see that your cones are pitted in bikes with quick release levers but seldom see cone damaged in bolt on hubs? Do your daily commuter customers complain that there brakes are rubbing and your truing work only lasts for part of a season and not years? Do cyclist ever complain about a click in the pedal area? Are these the bizarrely out of scope ideas you speak of? Your posts smell like bait. They are bait, Designed to get you to think. If you can not come up with an answer then as a group you can either come up with tests or 100% beliefs. The beliefs are dark ages showing its head in 2019. No one is lifted up in knowledge base or skill with belief. My knowledge is for sale, only because it has value, I also see that your community based bicycle organizations have value. You work hard and do great things, I have worked hard and I make great materials. Your moneys are tight and I am willing to greatly discount my work to help make your programs more profitable, improve quality, reduce liability, and more. Nicholas, if you see me as having no value to this group, ban me! If you think I work for free, Bite me! I want to lift up organizations that are open to improving the experience of cyclist and their businesses.
I'm personally requesting that you reconsider posting here. In this particular case, you even tacked your message onto a completely unrelated thread. I mean, might be I'm actually talking to a spam bot. Ok I am a bot, you caught me cyclista Nicholas

I will ask a few questions and I am seeking if you have tests to
prove
your answers.
Does a quick release lever change the adjustment of a hub? Yes or No is not important, how do you test to verify your answer is
important.
How can this test be used to reduce service time to 1/20 the time?
What does facing do for the customers ride experience? Nothing/ Something? The following answers are guesses, beliefs, not science
or
engineering based: it should be done, it is done at the factory, it does not need to be done, eliminates pedal click, professional
cyclist
have it done. So what does it do? how does it improve a cyclist ride experience? How do you verify your answer?
How do stainless steel spokes and cables stretch once and then magically become harder and never stretch again? If they do not stretch once, then how do they get longer once? How do you verify
your
answer?
Do Bolts stretch? Yes or No, how do you verify your answer?
How does a chain that can stretch at 900 Kg or 2000 pounds of force get stretched on a bike frame that can only support a 160 Kg or 350 lbs cyclist. How can a 45 Kg or 100 pound cyclist put 900 Kg or 2000 Lbs of force into a chain to stretch it? Without destroying
their
knees? How do you verify your answer? Which leads to the question, How does one type of shift lever make a chain function twice as long as another type. How do you verify your answer?
Why do mechanics tighten and loosen spokes? When a cyclist uses a wheel spokes get looser. Spokes only need to be tightened to round, dish, tension, and true a wheel. How can finite element analysis and computational fluid dynamics help a mechanic work 36 times more efficiently?
How can understanding the Sphere Stacking Equation improve the hydraulic systems on a bicycle? (Both hydraulic braking and
suspension
systems) and make cycling safer.
How can a mechanic use a bench as a tool to reduce service time 25%
Would it help your school, your students, bicycle businesses and cyclist; if your curriculum included verifiable testing processes, efficient practices to reduce procedure time 25% to 50%, service
sale
language to help cyclist understand what a procedure does to improve their cycling experience to improve sales?
If any of this or all of this is new to you and you would like to improve your training, feel free to reach out and start a
conversation
telephone only. 773 -490 -0683 Christopher O. Wallace . I am located in Chicago Illinois.
PS Yes I have re-invented the wheel three different ways, I am looking
to
improve the cycling industry and I feel schools are the best way to
do
that! I look forward to hearing from you.
Sincerely Christopher O, Wallace
