Can I add one extra suggestion for your third marble machine? Built the "music machine" first then focus on the power input (for a next world tour or for last in case you still have energy to spend on that). Why? 1- because if you just use an electric motor as power input (as all current church organs use), then you reduce "the fail chance" to complete a third machine. 2- because in order to design a manual power input that can play tight music, first you need to know what is the power loss by friction that you will have, which you can not know until you complete the music aspect of the machine. 3- The tight music mechanism that you want to use, like gravity, inertia and drag, all of them behave and scale different with the size, some of them depends on density (cube), others on area (square). At the end you can have a mechanism that requires so much weight and parts that could be unpractical to a world tour, or maybe they may require a lot of energy from your part to keep the machine moving, that would not allow you to concentrate in the other aspects of the machine while you play. Final, trying to reach the final design would be like chasing your own tail, because the first parameter that you need to know to design the power input, would be designed for last.

Having faced this conundrum myself, I smile to see Martin grapple with his bearing design from an emotional perspective masquerading as an engineering one. (not dissimilarly to the emotional reaction of many viewers to his staunch defense of his design). A good way to avoid emotional attachment to a mechanical problem is to fall in love with the desired outcome as a whole, not the pieces of the process.

Plus, he has probably introduced many more engineering focused people to music and art and how it connects to tech.

My favorite part is when he tells Martin "Better to be approximately right, than exactly wrong." I have felt this was an issue from the start of the new machine. If "tight" is the ultimate deciding measure, there needs to be a clear definition of "tight." Start by defining how tight is tight enough, then build towards that goal. Then any approximations/variations can be measured against an actual goal.

@AdelaeR

7 ай бұрын

True, but it's hard to know what "tight" is when you don't have a machine yet. For the power system, "as tight as possible" is a good goal, because the rest of the machine is going to introduce inconsistencies, but you want to start with a power system that is very constant and easy to operate. Martin's current approach of "how tight can I get it?" is a good first start to prototype and test out different designs and compare them. Step 2 should be: "How tight do I need it?" and step 3 "Is it feasible to get it as tight as I need it without getting overly expensive or complicated?"

@@AdelaeR He has a level of tightness in mind or the MMX wouldn't be considered a failure. His reluctance to define "tight" is leading to a rabbit hole of prototyping without ever knowing when it's good enough. There's wasted effort in trying to go tighter in all areas if it's not necessary. Including the power system. If a power system is easier to use but isn't as tight, he won't know if it will work better vs the tighter/harder to use system. It would disregard any benefits from alternate systems if they aren't the tightest. Currently, no matter what they build, they won't know if it's tight enough to use or not.

The first step in the process is no longer defined. It's a philosophical idea of "tight." Look, I just want him to keep it real.

And the bearing housing will be almost invisible on the MM3, so using off the shelf parts for critical parts like holding the flywheel is not a compromise from an artistic point of view. The art lies in the overall appearance and concept.

About the bearing housing, I compare it to electronics: There is a case for rapid prototyping, here we would maybe use a breadboard, a combination of vero-boards and evaluation boards. This is a perfectly valid method to get to results quickly, to find out conepts etc. You would never go into production like this, with a complex enough circuit not even for a single device. You would not meet environmental requirements etc. The design process starts with an idea. The validation of requirements is the key to success. Sometimes it's better to try a "stupid" design idea to discover potentials and problems. The thing about "stupid" designs is, you never know that they are stupid from the beginning. Sometimes you find it out yourself, sometimes you get someone who tells you, and sometimes you learn it the hard way.

Alpha worked. But made a mess. Beta worked well. But we found flaws in marble management which would have limited music production. Which was deemed unacceptable and set aside. Now working on Delta. Almost put an experimental bearing on a high speed flywheel. Thankfully the support team pointed out that might be a point of critical existence failure, and received outside consultation to be secure in our decisions. Continuing development. None of these machines are a failure. Failure would imply they never accomplished your primary design objective. Entertaining the public, making music, and sharing with the world. You already know Success Martin. You are complaining you aren't winning harder, because you didn't work smarter when you didn't stand a chance to understand the scope of your task at the outset. In engineering we call that learning the job by doing. Marble Machine 3 may still have defects. But 4 will improve upon those flaws. Perfection is only needed for mass production, as that will introduce its own imperfections, so ironing out the ones you expect needs to be done up front! If you don't believe me? Look up C&Rsenal.

This man can keep us entertained for nearly 30 minutes by just talking about bearings.

Martin should do a mini concert for the folks at SKF when his machine is finally finished. I think the employees there would love to see an innovative use of their bearings.

As a mechanical engineer with many years of industry experience, I know first hand what it feels like to feel in love with a design that may not be entirely practical. I applaud Martin for his willingness to reevaluate his design choices. This has been quite an emotional rollercoaster from when he first announced his bearing housings, I'm glad that the safety factor and the engineering design factor is being considered when the new bearing housings are being ordered. I'm certain that these new bearings as supplied by SKF will be the right choice going forward.

Wintergatan has REALLY jumped the shark here

I appreciate you being vulnerable and explaining more about why the criticism against that design was a sticky issue for you. I find myself as having the soul more of an 'artist' where non linear thinking, and bringing new perspectives to things is kind of required to make meaningful art. Weirdly enough I learnt a pretty similar lesson to you in my pursuit to get better at fighting games. I was trying to bring an artistic approach to learning these games. One of my friends put it pretty bluntly but it clicked with me. "In a lot of situations you just have to learn to do the right things, you don't have to be a special butterfly, you just need to block here or grab here or wait to attack, and when you attack you need to use these moves that actually get you a reward. And don't worry, doing things this way wont take away your special unique flavor, you just need to learn how to play the game" In a broader sense my life has been learning how to 'play the game' and not always outright reject a lot of systems like I naturally want to do. And to my surprise, there is a world of unique expression and individuality to be had when 'drawing inside the lines' so to speak. I hope this understanding gives you hope and encouragement to complete your wonderful machine :)

from amazed by your work to proud of your mind Martin.

Martin, you're on a path where you learn a tremendous amount of knowledge. You must and should make mistakes because learning also involves making errors. A bearing housing made from screws is not a negative thing, as it was one of the countless things that helped you learn something. Don't feel bad about the criticism you received. Feel proud that you dare to try different solutions and build prototypes. If you're lucky, you might accidentally invent something completely new.

But it also makes sense that before implementing a new creative idea that you check with experts first. *So, there is a place for Tried and True, but if it was only that then we never would have had a Marble Machine!*

24:31 Martin learns his bearing housing was not good for the final product, maybe prototype only. And why. But a final solution will be needed at some point, likely a tried and tested method.

I loved this video! So fun to learn along side you!

Super awesome and useful video thanks SKF for seeing this community!

This is great, it's so much fun! I love learning about mechanical things and seeing how it applies to your project as well.

The grand conclusion to the brearing housing arc. This video it's actually amazing, i love it! Can't wait to see more progress con the MMXT

thats a brilliant video for the hobbyist/amateur to understand one a very crucial part of buillding simple syszems with rotating parts. Thank you very much Wintergatan and SKF !!!

I know it's not a popular thought but part of the reason I enjoyed the first marble machine was its jankyness. Hearing the rattle of the marbles and the vibrations of the machine is enjoyable.

Very interesting.... SKF has always had a good reputation and it is easier to see why..... Russ

My forehead hurts now because as I've watched your videos, my eyes are wide ooen and my eyebrows raised high in absolute awe at your machines! Oh. My. God! Genius, pure genius! Bravissimo, Sir! Your machines are museum pieces, and I hope there some in musical instrument museums (and engineering museums) now, today! Brilliant doesn't describe what you've done!

It's clear how much your desire to be right is still overshadowing your ability to design.

I think if people hadn't reacted so emotionally to your first bearing housing you wouldn't have been as adamant about it; sure it wasn't the best long-term solution, but like I said in my first comment, it's part of the process, which is necessary to go through, and then at the end of the day you would make the best decision for your application. If people really want to unsubscribe for something as simple as a few metal rings with some balls in them, they really ought to; one less thing to worry about. I'll still be here tho, I've loved seeing the process this entire time, regardless of the bumps along the way 💛💚

Thanks for this. Superb video, love the chemistry between you guys.

Good to see that you have not lost your bearing on reality, Martin!

The process that SKF went through to design their bearings is also a form of tinkering. Every innovation is. I believe it helps to accept that others have a lot of experience in what they did for so long. And to be able to stand on the shoulders of other tinkerers can be very helpful. In the end, it comes from one tinkerer with quite a bit of experience in their field … and goes to another tinkerer to benefit from that. Of course, challenging existing designs is sometimes necessary. But going through the process with Roger and SKF helps to find out if that is the case here or not. And Martin, there is so much of you in the Marble Machine. It is not necessary to (re-)invent every single part and material.

This made me learn a lot! Thanks Roger. Very good representation of skf!

Watching you build a whole career from one crazy contraption never fails to make me smile well done bro.

Excellent video! Very formal and informative. I completely agree with everything Roger explained here

As an engineering student, I find this very entertaining and helpful.

We're back baby! M. M. Molin, Winergatan Wonderland, MM. III

I stopped watching for a while because I was finding things frustrating, but damn, you've really grown. Proud of you, and I get how hard it must be to balance between the artist and the engineer.

Very good introduction to bearing design ! I learned a lot !! like usual, big big Thanks !!!

Lovely video. I’m working on my own synthesizers, and I’ve also seen the grey area that comes when you’re between art and engineering. and you make a good point that this divide is exactly why people love your projects. Keep being awesome!

I absolutely agree with the tries and engineered and tested methods but I also love the improvised "first test demo" approach. Lovely video. Awesome intro to skf software I was not aware of. I will put it to good use. Thank you!!!

That was a great video Martin!

I’m so glad you’re back, man

Love the opening shot - standing inside an "artistic" bearing!

Hey Martin, your bearing housing is proof that you are creative. If everyone always used proven and trusted methods, then we wouldn't invent new things. Your housing was perfect for a prototype build, where you can test whatever design you want. Then using the proven methods for the real design unless yours exceeds those methods in their functionality. :)

Man, that's some nice editing in this video. The content is great too, but the editing blew me away

This is amazing content. I learned a tremendous amount from this.

Very good work you two. Very interesting and useful information

Your machines may have failed, but you did not. You gained experience and learned. This is the scientific method.

He's still repeating the same mistakes from the last two attempts: "dumb design requirments"

Absolutely amazing video. Thank you!

I spent many years working in an industrial environment. A good portion of that time was spent in plant maintenance and, since it was a small company, I did the maintenance purchasing as well. I learned very early on in my career that SKF bearings should be used in any situation where failure was too costly. I hesitated to buy anything else. If I sound like a fanboy, so be it. Martin - ask any mechanic walking onto a shop floor at the start of the shift “what is the first sign that something is not quite right” and they will tell you that “it sounds different today.” I had that same experience many times despite the complexity of the environment. Even the most subtle change evoked a response - my version of the difference between ‘good’ and ‘bad’ music. When you can’t track down exactly what the problem is, consult those who have been thinking about it a lot longer. Another way say that is “if you can’t fix it with a bandage, an aspirin, or a good night’s rest, call the doctor! I’m glad you listened to that advice and I can’t wait to hear your next ‘failure.’

Combining the Huygens drive with the Governor and flywheel is the best solution i think 🙂.

GG! Looking forward to the next video - superb production!

Ah, that beat before 'dammit' was classic

What an awesome learning lesson video!

Love this episode!!

I love SKF! I used their online tool to find bearings for a university project 😄

This was so cool. So much knowledge. You should do these videos more often, something like "How to Design and Order Laser Cut Steel" :D
