This is part 1 out of three of the MK2 micro Tesla building series. After watching this • Micro Tesla Turbine Ge... I decided to give it a shot and see if I can improve the performance of the previous micro Tesla turbine. Big thanks to Tesla Tech / @teslatechua , as without his valuable input, I wouldn't have thought this design, which seems efficient and capable of achieving high output numbers considering its size.
Some interesting data:
MK1 MK2
Rotor diameter: 20mm 25mm
Number of discs: 12 18
Clearance between the discs: 0.18mm 0.12mm

I will say though, I’d prefer the sounds of your machining alone without the music. Always posting great videos though 👍🏻
ROCK N ROLL WILL NEVER DIE
You have sound?

I agree
defo a ffwd vid
This channel is one of the best kept youtube secrets, your channel has grown so much since I first saw it.
Can we all just take the time to appreciate the amount of freaking precision, dedication and time that goes into making this stuff, and these videos.... Can't wait for part 2!
Absolutely astounding job! I'v never seen such precise machining being done before.
That's gonna hit some major RPMs with the tight spacing and number of plates.
I wonder what the resonant point at which efficiency is best at will be.
Usually, once a Tesla Turbine hits a certain speed, the acceleration really takes off.
thats not precise...it's what a tool maker/master machinist such as myself considers ball park (+/-.005). 0.0005-0.0002 can be held on manual machines all day by someone experienced. Precision grinding, even tighter tolerances. 0.000005 isn't uncommon on a manual precision bench grinder. CNC is even more precise.
Great workmanship and ingenuity on getting those small components made. Good job on the video too.
Inspiring craftsmanship, love it! Thank you.
Protip, make yourself some punches. That lathe will let you get it done in no time and to good tolerances, then you can punch out vanes, spacers, and other round parts in moments instead of having to hack them apart with scissors.
That being said, holy crap, awesome work on this
Loving your work Johnny but did you know that an aluminum can has a thick and thin wall the thin wall is in the middle. Awesome work Johnny
Hmmm this is good to know.
Love The precision in this video
+Rulof Fai da Te Thanks Rulof!
+Rulof Fai da Te Ciao Rulof :D Sono felice di vederti qui
You look like Ricky from Trailer Park Boys.
that's really funny comment, bro! there's a precision since the first second... I mean first, not second... and metal is a metal, is it not? A Disk is a Dick (ooops, my mistake) - a disk.
@@ml.9746 yes!!
You're a talented craftsman. Very impressive. Thank you for sharing.
If you used this to spin up a metal spinning top, you'd get in the record books for the fastest, longest spin.
Your videos are awesome, thanks for sharing.
I can't believe how much I frikkin' enjoy yer vids Johnny. Really brings out my inner engineer. And now you are honoring the legacy of a true scientific hero. Thanks!!
Beautiful work.
I also made a couple of Tesla turbines, but I think I need to have another go at it having seen this inspiring video.
Very relaxing to watch this video, maybe because the background music, because he doesn't speak, and the patience of doing so many little spacers in the lathe or combinations of all of them...
Super smooth! O.o
Very satisfying to watch.

Hi.
Absolutely delicious nice job.
Excellent video and craftsmanship. Great job!
Very nice work but are you sure that the soldering process distributes the solder evenly enough for there to be no imbalance issues at the speed this is likely to be rotating ?
Great job!! looks great! Really enjoyed how you made the spacers and the disks!!
For a long time, I've been obsessed with the idea of creating a tesla turbine with a tesla valve integrated into the discs of the turbine itself. Imagine a series of the valvular conduits, embedded inside a disco, radiating outward from the central hub, to aid in compression of gasses/liquids at the outer edge. Basically, just a tesla turbine that spins valves instead of just the discs normally used.
What do you think? Has anyone ever heard of such a thing?
This guy is the Leonardo Da Vinci of craftmanship!
My hat off for you, mate!
Dude this is everything I've always wanted to do and more... Keep up the great vids!
Great machining and nice backing track. Sounds like something I would do.
Don't bite my head off but i watch all your videos over and over and and enjoy the actual sounds of you assembling things,using tools please say this backround music is not gonna stay plz
No idea what i just watched or how I got here, but I watched all of it, and now i'm watching part 2
Should’ve just gone and bought shim washers, but I admire your efforts
Fascinating, well captured on video. Thank you!
A very firm hand, indeed! And what a patience!
Excellent work! Have you ever thought of putting a valve phase plate, interleaved with the exit ports? I know you understand the compliance/compression principal because I watched your pulse jet video... think "rotary valve" pulsejet. You would need different material for your disks though. Can't wait to see what you do next. Again, excellent work.
Nice! I just cannot wait the test of that turbine!
I thought I would hate that music, but it grew on me quick and I fell right into that pocket. Groovy stuff. Reminds me of Tool.
While I understand the reason for adding the supports further out along the disc. The noise made from the Mk1 wasn't due to disc vibration from inadequate support. Tesla turbine RPMs are supposed to reach very high rpms, before they reach the optimum level the airflow is turbulent, resulting in vibration and noise, your supports take away from surface area and create pockets that will maintain turbulent flow, not to mention a smoother disc is preferred. When the turbine is at optimum the volume drops because the airflow becomes laminar and more air contacts the disc in a spiral pattern spinning the disc faster due to more contacted surface area. You're the only channel I've found that machines their parts rather than prints them and have the greatest potential. If you need to see to believe the volume drop and switch from laminar to turbulent flow look up YTEngineer's tesla turbine, he demonstrates it, the exact RPM at which this occurs is still different per every model build and often do people stop applying airflow too quickly when RPM starts to creep, but that's not max, it's sorting the flow to change from turbulent to laminar which requires certain pressure and energy. thus Kinetic energy transfer slows before higher efficiency is gained. Even if you don't read this or listen, keep up the good work, less and less machinist today.
You would very much be interested in the Tesla turbines that Charlie Solis builds then. He machines all his parts himself, mostly cnc the complex geometry stuff in the small 6040 Chinese cnc machines in his shop. Actual power and torque outputs even at low RPMs with just room temp compressed air. 2.75kW and 6.22ft-lbs of torque at only 4150rpm. As well real 1200watt electrical load output tests on all the way down to only 65psi... all on a plastic and aluminum Tesla Turbine prototype…. This dude has a degree in physics too. Knows his stuff.
Muito bom, aguardando a parte 2 :)
Love when you upload long videos like this and am thinking of getting a lathe keep up the good work johnny! ;)
If you started from the outside edge first making smaller circles inward, you would have gotten a few more of them!
But when you start figure out how many could fit back to back (circle to circle)
And the odd one out that won't fit, what is the measurement on that wasted space, and divide that measurement up so all circles are symmetrically spaced apart, you can figure the rest from there...?
Why does no one think without thinking anymore. One half second later after seeing what your doing and this realization slapped me in the brain 🧠
Fantastic work! Thank you for creating
Jhonny te felicito, eres el mejor! Congratulations! you are the best!! (sorry for my english) saludos desde Uruguay!
Incredible work! Such precision!
Great job.I like that your video did not have super cheesy music in the back ground.I approve of the heavy Pink Floyd style jam.Sounds good.
Extraordinary Work And Precision .
Im interested to see how this performs in comparison to the Mk1. Youve thought of a very interesting way to vent the exhaust to one side!
I really like your building techniques, (and your progress curve looks really good too)
Now, some constructive criticisms ^^ :
The spacers and spacer axles are waaaay too big for such a small turbine, they are going to destroy the laminar flow, so the turbine is going to work more like an impulse turbine (working fluid pushing against something) than a boundary layer turbine.
I would either make a bigger turbine with the same spacer dimensions, or use brass whire and really small spacers (yep, i know, making them would be a pain in the ass)
With that said, I'm eager to see part 2!
6:05 umm, those look exactly like flywheel shims on a VW 1600 engine. The 4 holes and everything.
Great job. Perfect detail.
You should make a tour on your work Area.
it will be nice
Nice, I am waiting for part 2

O mein Gott, das primitiv Kinder video.
I to am waiting for part 2
Nimic ,canci,semit net hărăzi.va flancuri!
Been watching you way before NightHawkInLight shouted you out and you started booming. Keep up the entertaining videos man!
Cracking video, can't wait for part II :)
Very satisfying watch. Love it!
Seems like a die/punch tool would have been a good way to make all those pieces. But your attention to detail and brute force approach is to be commended! Great determination getting all that tedious work done...
Nice Video, I hope that the turbine works as intended, the solderings are a bit stronger if you first hear the material and then add the soldering material instead of first adding the soldering material and then applying heat.
Very interesting. Thanks for taking the time to publish this video series.
Great vid. Just curious, would a hole saw bit not have been way more efficient and time saving for cutting the large discs?
This is very creative !!!Anxiously waiting for Part2.Thanks Johnnyq90.
It was so satisfying seeing those being trimmed by the lathe
I loved that video!! im ipresoned by you! i hope the second part is very soon! hello from Mexico!
I noticed the bandaid after removing those fine circular blades! :)
Great craftmanship, as usual. It is always a pleasure to see you work. But still, i'd like to get some light on designing criteria. I find quite surprising how you move away from usual tesla turbine design. Why a bigger and single exhaust radius? Won't those 4 tubes with their respective spacers disrupt the spiral flow around each disc?
Probs couldn't penetrate all the discs without snapping a smaller bit.
JonnyQ90.
MIIK Platinum Medal.
wonderful work! when will be part two?
by the way, will this rotor work also with fluid?
This is amazing skill right here.
Pepsi! You heathen!
This was a lot of fun to watch. Thanks for the video.
Nice craftsmanship
Funny how you started the video without a band-aid. LOL. I love your work i must subscribe.
Awsome precision work
Salutes to human achievements in science and technology.
You have done a great work
When cutting a sheet I heard transformers metallic sound, nice work bro.. 👍
Mechanical engineer is always fascinated how easy task for few minutes can be realized in incredibly complicated way...
Very good work. Impressive .. Congratulations! We can learn from you ...
Beautiful work!
7:04 - thinking: there's going to be some more elastoplast appearing soon! :) Superb video.
the "enlarging holes" sand drill gave Me chills
el diseño en el disco azul con el compas es igual ala flor de la vida buen video saludos
more enjoyable than a blockbuster movie
I´ve watched the whole video with opened mouth, because I like such crafting. Great job! But one question remains: What is it for ? I rly don´t know.
+essaynLulz it's so we can talk to our extraterrestrial overloads
en.m.wikipedia.org/wiki/Tesla_turbine
So what I'm gathering, this could be used for pumping as well as turning a shaft with a practical catalyst.
Two words free energy by harnessing the power of the wind I'm assuming because it's some sort of turbine which is meant to turn
@@JackDaniels-st2ei with next to no torque.
I loved this video! I just need to point out that the moment you chose to add the four posts to secure the fins, you have added a contact point for the water to hit and thus push. This is closer to a turbine design. The Tesla design was about surface contact and your posts would interrupt the waters path to keep viscus tension at speed.
Wonderful job though! Keep up the great work! Amazing...
Agreed! Johnny does AMAZING work! Necro Diem you know your Tesla turbines. lol The new Tesla turbines built by Charlie Solis have avoided this problem by implementing Nikola Teslas Improved Turbine disc stack patent GB 186,082. It was patented 10 years after the original. Basically dimples/raised protuberances are just pressed into each disc near its periphery and those raised dimples keep the spacing in the periphery. This way there’s no lifting surfaces for the motive fluid to impact with. Tesla really figured it out with that improved patent design.
for mk5, cut the discs from the metal plate with a knife instead of scissors, glue them on a bigger arbor (like last time) that you machine with it, then drill the 4 holes using an electronic lathe index attachment, at 90 degrees of eachother, heat the discs to get them of, then wet sand all discs, then reattach (without glue, just pressure) on a bigger arbor, and machine, and sand edges
Amazing work!
That's either an amazing little cnc lathe or you are one hell of an editor!! Fabulous workmanship!!
+gentharris Thank you, it's a manual lathe.
Very nice, excellent work..and music is awesome
Nice build but the disks are too close together to take advantage of the boundary effect. When they are that close together the medium fricts on both sides of the disk. You need a wiper gap so it only fricts on on side of the disk while leaving a gap between disks otherwise the faster it turns the more force is exerted in the wrong direction
Disc spacing doesn’t effect centrifugal head. That’s determined by the peripheral velocity of the discs. This is true for ALL centrifugal pumps. The discs cannot force the fluid in the radial direction. It only ever produces or receives a force/torque that is tangential to the rotation, never radial. The radial or centrifugal head is due to the inertia of the fluid in rotation between the discs.
As well this disc spacing is totally within acceptable ranges. Charlie solis even has 10in diameter 75 disc tesla turbines that have 0.0098in wide disc spacing and it’s the only tesla turbine on TH-cam that’s actually outputting real power and torque. With actual proof of it too. Peak 2.75 kW and 6.22ft-lbs of torque at only 4150 rpm too. And real 1200 watt electrical load outputs sustained with just room temp compressed air all the way down to 65 psi too… All with a plastic and aluminum prototype.
For optimal performance decrease distance to 0.4mm so that no free flow cannot pass through the gaps in which the barrier particles can spin at higher speeds
There is no one optimal disc spacing. Tesla says this himself in fact.
“The dimensions of the device as a whole, and the spacing of the disks in any given machine will be determined by the conditions and requirements of special cases. It may be stated that the intervening distance should be the greater, the larger the diameter of the disks, the longer the spiral path of the fluid and the greater its viscosity.”
Lesics, or wherever you got the 0.4mm spacing idea from, is patently wrong about that being “the optimal spacing for Tesla turbines”
Charlie Solis has actual real working Tesla turbines that output real power and torque at even low RPMs. He’s built and shown working power and torque outputs at 2.75 kW and 6.22ft-lbs of torque at only 4150 rpm with only room temp compressed air. And even real sustained 1200watt electrical load outputs at only ~6500rpm on room temp compressed air down to 65psi.
Righteous work!
I hope this man is never let near to a dremel tool ever again
I have a question: you use superglue to hold them in place on the mandrel, but when you are done they seem to just pop right off. How does this work? If the glue is actually holding them, shouldn't they be harder to remove?
NICE! keep up to AMAZING work!
Lovely job, precise engineering, one question, what is it??
YES , come on and get more suppressed TESLA technology out there, we need it ...
Wow! You are a genius!
Patiently waiting for part 2.
What turning machine (lathe) would you recomend ? I am planning in buying one
Time always stops, when I'm watching your videos...
So you have access to a lathe and drill holes with a grinding stone?
Wouldn't hole saws save a lot of time when cutting out the disks and spacers? What is the optimum separation for blades on a Tesla turbine, and do they work better when rough or smooth?
Interesting job good explain by practical. Very nice thank you🌹❤🙏
pure genius !
do the spacers not affect the circular airflow that the Tesla turbine works from ? but super cool work
JACK I agree. I'm just an machine engineer but from what I see I'm sure it has a terrible effect on the efficiency. I was actually almost crying when I saw so much machining skills wasted on that bad design.
Hello! I liked the video, only one question: as it is called around you use? Thanks!
Wow amazing work
im pretty sure hitting the glued discs with a blowtorch for a few seconds would have loosened them up. besides the fact, great video!
