I'm an aerospace engineer and I am really beginning to like this channel. I'm not certain what his background is but there's genuine creativity and innovation in this and that is rarer than you think. there's an engineering methodology called integration where we take existing unrelated things and combine them into a new solution. It sounds very obvious but its far from what many engineers are taught and even further from what they practice. Engineering practice is dominated by business concerns not innovation. if you breakdown what a lot of technology companies actually do there isn't as much innovation as the PR claims. Jeff Bezos has publicly admitted that Amazon isn't that innovative. Internet marketing existed and parcel deliver existed, he just combined the 2. Combining the 2 in the way he did was innovative, being a greedy sociopath who pays his workers minimum wage was borrowed from others. Its why I'm liking this channel more and more, there is actually stuff I haven't seen anybody else do. They way he machined the eccentric shaft was very clever.

a miniature turbo does not give very good results (video of 04/19/2019) I would opt for a miniature screw compressor because the intake pressure is stable which will be better with a carburetor, for a turbo it would be necessary to have the same pressure in the fuel tank as in the air intake, the tank being partially filled with air this would create a pressure delay at the fuel inlet in addition the tank must be able to support the pressure
@@Spip-yt6dx a draw through turbo setup would be a better choice vs a "blow through" turbo setup. You wouldn't have to deal with "boost prepping" the carbs nor matching the tank pressure and maintaining it at a 1:1 ratio. Downside would be the compressor blades would slowly be eaten away, but very doable. A screw style supercharger would be cool to see either way.
@@jeffbroxton988 if this kind of installation remains miniaturizable and takes into account the admission by carburettor why not (PS: I'm not sure what "draw through turbo" means in French)
My deepest respect: You have some great knowledge, training and skill in mechanics and engineering as well as a well sorted machine and tools set. I also admire your clean and tidy working area.

I worked as a technician rebuilding gearboxes in a machine shop for about eight years. I didn’t do a whole lot of machine of the parts. Every once in a while, I could run a manual lathe or something like that, but my jaw was on the damn floor, most of the time watching you build this motor it was very impressive.
If Johnny entered Robot Wars, he would win every season hands down. What a talented person. Honestly this is my favourite TH-cam channel, and the only bell notification I have. Brilliant as always.
Johnny, you’re a GOD! Most companies that make engines use a team of specialists. A one man show making an engine that sophisticated is nothing short of incredible. It runs, and runs well! I couldn’t even imagine how to do this!
Just watching those machines do their work is SO cool imo. The amount of engineering that has to be involved is just mind blowing. Hat's off to you bro.
Retired Engineer after 37 years opinion. The CK45 is ANSI 1045, or Cold Roll and makes a good shaft, if it runs straight and in balance, the eccentric changes the weight factor or centrifugal shift of the shaft. Make the shaft out of 4140. And turn the jets on the intakes down. That has to be fuel exhausting. But a kick ass motor for sure. Great job.
I'm a trained machinist, and while I worked as a toolmaker we hardened every tool (mold) that I made. This was molds for injection moulding (plastic) and they were hardened when the machining was done. I wasn't directly involved in the hardening process, but as far as I remember the technique was to heat and then cool the molds fast for a very short time. This was done to only harden the surface of the mold, but keep the core soft. This way we got a hard and durable surface while the core was soft enough to not break/crack by the enormous force the molds were subjected to during the moulding. As far as I remember we didn't have to calculate any shrinkage of the steel the hardening because it was only the surface that was hardened. We had to calculate for the shrinkage of the plastic, but I don't think shrinkage of the steel was a factor. I can't remember what kind of steel we used, but it was quite soft and easy to machine before it was hardened. I would recommend you to buy steel intended for making molds and find a description of the hardening process online. It's 25 years since I worked as a toolmaker now so I have forgot a lot of the details, but I have a friend who works as a toolmaker and if you want me to I can ask him for advice about the type of steel they are using as well as the hardening process.
Sir I have never seen artistry like this. I have no idea what your doing most times but I know this a passion for you. Thank you so much for exposing me to something I did not know I loved. Please continue your work and giving us a look at it.
The flywheel stores energy on a power stroke and releases it during lack of power stroke, delivering its rotational energy to rotate the engine instead. Considering the size of the engine and thus lack of weight to keep the rotors rotating on their own, it's indeed a good idea. A well-balanced wheel shouldn't snap the eshaft either, and balancing a wheel is just a case of making a small inset where there's just that tad bit of material too much.
I actually own a 13b peripheral port with 48 IDA carb, and at wide open throttle, it consumes 1 litre of fuel every 2 km... 300hp and flame out the back, makes me laugh at the fuel consuption
In 1972 I bought a twin rotor NSU Ro80 and it was thirstier than my friends Rolls Royce Limousine . I converetd it to run on LPG and injected oil into the inlet manifolds to get over the total loss system fitted, which made it run sweeter, and cost less than half to run on LPG.
I know I’m a year late to the party. I have had success pressing a pre made hardened sleeve on the the area where a needle bearing needs to run. May or may not work for you. Thanks for the time you spend sharing your projects.
@@octane613 I think with the tools he has and maybe a bit of external contribution he could probably fabricate all the parts by himself... probably for the irons and rotors a bigger cnc is needed but aside from that... apex seals, bolts, spacers... I don't think for him would be too much of a stretch... it is a stretch for the wallet I would think...
nice, I love how it looks and sounds, I would like the see you harden the existing one and also make a hardened steel one and compare the results, check the rockwell scale of each
Well i'm having a good christmas so far, this week, not only have I had this satisfying machining video but i've had one form ThisOldTony and Clickspring. So much goodness
I must say, this is awesome. I'm working on a project and I need a high rev, high torque and high power engine with low weight and as small as possible. These engines should be locally prouduced. If you are interested, kindly respond to this comment
Had a friend that had a (I think 70's model) Mazda RX something. He loved it but said you had to be careful because they use up the motor oil. The nature of the beast. People burned out the motors because they forgot to check the oil EVERY TIME you stopped for gas. Classic "Fill the oil and check the gas" for oil burners. Be fun to compare it ci to ci with conventional miniature cylinder engine. Having fun watch you build it piece by piece, What a Hoot!...
@@Dubz0408 The biggest challenge would be to synchronise both engines to run the exact same rpm. I think you would need something like a centrifugal clutch on each engine to allow for some slippage
You can boronize your e-shaft to get the hardness that you want. The process melts boron into the surface of your part making the surface extremely hard while retaining the strength qualities of the softer shaft under the surface. On top of that, the boron also acts as a lubricant on the touching surfaces. The process adds a small bit of size to your part so you have to consider that when you are machining it.
Love your stuff! Also, just pointing out that if you had a third rotor it would be self balancing and not necessarily need a flywheel... Keep up the awesome projects!
IT IS INCREDIBLE ALFO, I AM CARLOS I LIVE IN TIJUANA, MEXICO. I AM A LOVER OF ROTARY ENGINES AND I AM SUBSCRIBED TO YOUR CHANNEL AND TRULY WHAT YOU ECHO IS SOMETHING SURPRISING, YOU HAVE A GREAT TALENT HAPPINESS
Using pre-made fan blades? Man, what a rank amateur you are!!!! :-) Seriously, some very impressive work. Watching videos like yours, I wish I had learned metal machining in my youth. I'm too old to start now.
To harden your existing shaft, you could use a case hardening powder like Kasenit. Your motor does need a flywheel and i would suggest incorporating another counterweight into the design. In the Mazda rotary engine, a flywheel was cast with a heavy lump on one side to act as a counterweight. You could do the same out of steel making sure that your off centre lump is equal in weight and opposite position to the front counterweight. Well done on your fantastic project.
I was waiting for this video ever since you made those plates and e-shaft🥰 As for hardening of ck45 steel is very simple since it's non stainless tool steel (that means it doesn't require ridiculous austenizing temperatures) so it doesn't need oxygen protection either.. Thank you for upload men🙏
I would recomment using 1.2379 (X155CrVMo12-1) for the shaft and try to harden it by induction heating. should be a rather cheap but durable steel for this
Wanted to write 100% the same. Should be a good and fairly cheap way to do what you want. If you want to have extra strong surface, you could add some DLC coating.. Depending on expected torque, you could leave the center quite tough and the outside high hard by induction hardening + maybe good dry running with a coating.
@@marcels.647 i haven't seen any measurements for the shaft diameter but i think it is beefy enough to withstand the low rotary torque. he should only harden the contact surfaces though and not all the way to the core of the whole shaft. i hope he sees this or already knows about this since induciton is pretty much the only solution to precisely heat up such a small area. for the coating part i dont know of any good diy solutions that are worth doing at home.
Haha, good luck with that. You'll be making all sorts of scrap metal from perfectly good stock in no time. I happen to be quite skilled at it with my mini lathe.
@@Sven_Hein Guess whos BUILDING his first lathe.. those things are expensive as all hell here in any reasonable hobbyist size that is. Rest are too far, require expensive truck to transport and require industrial size main fuses. I wont be building this accurate micro engines anytime soon with it, but going to get bushings etc made that beat using drill to turn part and angle grinder to remove material...
Really running rich. Need lean that bad boy out. When it started sucking air you could hear it crisp up. Awesome build btw.. Cant wait to see once you get a hardened shaft.

@@omeharto288 you can buy them, they are made by O.S. but they are expensive.
@@leemilica ah my bad
The internal wear was looking great! Nice an symmetrical. Great job!
I know he's leaving them alone, but I want to liquid cool the plates so fucking bad.
Best craftmanship ever
Guess who just got his first lathe?!
~me
Haha, good luck with that. You'll be making all sorts of scrap metal from perfectly good stock in no time. I happen to be quite skilled at it with my mini lathe.
@@Skinflaps_Meatslapper yes probably, but hopefully something useful sooner or later.
@@Sven_Hein Guess whos BUILDING his first lathe.. those things are expensive as all hell here in any reasonable hobbyist size that is. Rest are too far, require expensive truck to transport and require industrial size main fuses. I wont be building this accurate micro engines anytime soon with it, but going to get bushings etc made that beat using drill to turn part and angle grinder to remove material...
Try chroming the shaft will help with reducing wear. Brilliant work you deserve a Nobel👌
Лайк 👍
this is a really badass channel. you are one hell of a machinist.
What to do when getting an rc engine, use it? NO, REBUILD EVERY SINGLE PART TO MAKE It BETTER DON'T EVEN TEST IT WITH THOSE HORRIBLE PARTS.
I would love to see this guy build an engine from scratch.
With the tools he\she has now that is possible, excluding the Misc: Spark plugs, tubing etc...
Симпатичный моторчик!, судя по видео вибрация не маленькая. Удачи Вам в постройке и модернизации
Really running rich. Need lean that bad boy out. When it started sucking air you could hear it crisp up. Awesome build btw.. Cant wait to see once you get a hardened shaft.
Great work as always brother. Love your content. Can we all just appreciate the time and money that goes into this man's projects? Amazing stuff.
Great job young man, I can't wait for the next 'Evolution ' 3 Rotor setup.
Listened through my Bluetooth earpiece and it just scattered my eardrum when it started! That thing is rowdy!
2 rotor❤️engine this channel is awesome. With this engine an rc rx7 would be great. Merry Christmas.
