I think a lot of people that don't know machining or engineering wouldn't have any idea how much effort it takes to make something like this. Especially with how amazing it ran! They always say you can tell just how good a motor is by how it sounds and how smooth it runs... And usually engines on the smaller side (especially 4-stroke) can be a little finicky. When I was in my junior year of tech school i made a single cylinder pneumatic motor that had a small generator rigged up to it, I wired it to a small maglite light bulb and that was about it. It took a good bit of machining and I had to get the tolerances pretty tight but it was an awesome project! It's almost 30 years old into this day you can still start it right up and it purrs like a kitten! Even the original maglite bulb still works
I truly agree with your comment. It sometimes breaks my heart when people talk about this build as if it's not a big deal. Of course, I made it for people's fun, but on the other hand, I don't want people to take it too lightly. In particular, some people ignore gasoline engines as old technology, but I hope they think about the basis for today's new technology.
I respect your past achievements and wish you all the best in the future.
what machines did you use because i would love to do this my self
Tools I Use: maker-b.com/pages/tools-i-use
thank you@@MakerB
i just came back from my 3rd semester at machine school, i made a 4 cylinder radial pneumatic engine, it turns pretty good unfortunately the vaulve system we used was not designed for that engine and it is quite primitive, so the first time i tried to run it, it made the crankshaft uneven, so now it dosent run as smooth as before, i shouldreaally just disassemble it and straighten everything out.
now that's a 1 cylinder, 6.6 microliters, 120 mousepower engine that goes from 0 to 60 feet/h in under 3.5 seconds
Mouse power, feet/h hahahahahaha 😂😂😂😂
I'd try to overclock it, might get half HP from it
@@paveljelinek772 maybe a big Garrett turbo will help it make that 0.5 mouse power
NIce
Well done 😂
No talking, no music. Just awesome stuff being done.
I spent my youth and early adult years competing in racing control-line model airplanes that had 2.5 cc engines. (FAI Class F2C - Team Race) There were many aspects of the sport/hobby that were required in order to be successful, from a light but strong model, to a high performing quality motor. As nothing competitive was available off the shelf at hobby stores, everything was hand made, from the model, to in some cases the motors itself. We had a highly skilled machinist who for several years made the motors from scratch, while in other years we relied on motor specialists who had mini mass production runs, and made their motors available for sale to some competitors. Motor technology was continuously refined and performance improved and the motors became more capable.
My brothers and I raced planes with diesel (compression ignition) two stroke motors that had to fly in 100-lap qualifying heats, and 200-lap finals. There were strict limitations on plane dimensions, including fuel tank size. Essentially our plane had to fly at about 125+ mph for at least 33-laps on 7-cc of fuel, then make a pit-stop to refuel. A really good 100-lap heat race time including two pit stops is in the low 3-minute range.
A successful racing engine is all about metallurgy and precise tolerances. We bought some Russian-made motors which were consistently winning at the time, and our machinist couldn't figure out how they made the pistons, which are critical to success. It appeared to be some sort of sintered blend of aluminum that was high in silicon. As our racing motors were always run lean to get the most range, they ran very hot, so the science behind pistons was in how to control thermal expansion at high temperatures so the engines didn't seize while running hot, yet expanded at the same rate as the cooler cylinder to maintain compression, while being hard enough to show little wear after many races running with low percentages of lubricant in the fuel. Cylinders were typically chrome-coated and had a very slight taper so that when pistons were lapped to fit they were 'tight' at the top of compression, yet ran 'a little loose' through the rest of the bore to minimize friction.
We had to learn a lot about everything from aerodynamics; construction and design techniques; materials science; combustion and fuel science; to competition strategy. We were lucky to receive 'free samples' of new high-strength materials, such as just developed Kevlar and Carbon fibre, from companies like Dupont, and fuel additives from Shell, who were willing to support our efforts. We we lucky enough to qualify on the Canadian team about 6 times to compete at the FAI Control-Line World Championships in Europe in the 1970's, 80's and 90's. It was a great learning experience and an opportunity to travel and represent our country in a highly competitive and technical event.
A quick search on RUclips of - FAI Class F2C - Team Race - will show what the racing is about.
Я тебе открою секрет тех поршней... Их делали из сплава типа САС50 такой сплав вообще шёл на изготовление деталей моторов для грузовиков.
@@user-Hetzer Thanks for the info. I did a google search for this alloy but nothing came up. Can you provide more info?
I don't know of any competitor who still makes their own motors, like our Canadian Team did. There are motors that are competitive at reasonable costs from motor builders, so no one tries to duplicate them. I've not competed for a few decades so I'm out of the loop on such things though.
Короче вам нужен поршень от машина ЗИЛ 130. Состав сплава я точно не знаю, хотя инфу можно найти. Это не секретный сплав. если хотите то напишите в личку рад буду помочь как авиамоделист авиамоделисту.

if only youtube had Oscars, the award for content creation would go to this guy.
I'm a Civil Engineer, but this video made me respect the mechanical engineers, even more.
salute to you sir.
That's quite a compliment! Glad you enjoyed it.
Just so long as you still hate architects. All is still right with the world.
Well approved by an aerospace engineer
Accountants will be the iternal enemies of engineers more than architects
@@prasadchaturdesale5795 No. Architects are hated by everyone from the carpenters, drywall guys, electricians, sign makers, tile guys, EVERYONE HATES ARCHITECTS
You should have a look at Electrical engineers/Computer engineers at ASML, its almost science fiction haha.
On behalf of all engine heads, thank you for this awesome video and thank you for your creativity. God bless 🙌
Thank you very much!
Literal engine heads or engine heads? 😂
For real man I'm blown away with this
@@MakerB where are you from
@@isaacsrandomvideos667 engine heads
This was insanely cool! I've been a machinist for many years and this takes it to a whole new level! You could sell this as a DIY kit and I would buy one. Very cool and Good Job!
Glad you liked it!
I would buy one also.
DIY kit? Yes, please.
id buy 1 to make a mini RC car
@@JT-91 Me too
Very impressed. No matter what, you'll always have that little engine as a reminder of your skill. Great job man!
hold my beer... 😂
You made me a bit sad, because as a software developer, I will never have a way to create a reminder which is part of the physical world like this little engine
No
Well, until the brass connecting rod destroys itself. Or the piston galls itself against the cylinder sleeve. Maybe he threw some molybdenum disulfide in there or plated the cylinder or piston.
One day it will be in the landfill and you’ll be in the bone yard
If I may ask, how great did it feel after 1000 hours of design and building to hear that engine start successfully? This was beautifully done and well executed. Nice work sir!
I thought 1000 hours was gonna be the time lapse of engine wear after 1000 hours of use. :) Wasn't disappointing.
I was thinking the same thing. It must have been a very gratifying feeling when it cranked up.
I would have dropped a load in my shorts.
@@devinb5937 Have you ever heard of such thing as doing stuff for fun? No?
Wow @@devinb5937 they should put you in charge! I’m sure we’d be well on our way to finally solving climate change as soon as your administration cracked down on the tiny machinist hobby community.
This is like watching an artist work sir! The perfect machining, to the exact tolerances required, to create such a small scale working engine. Mind blown...
That's quite a compliment! Glad you enjoyed it.
I've watched this and now I'm trying lift my jaw from ground. So much precision, so much skills, so elegance, so perfection, so magnificence. Great job bro.
I love how he didn't explain anything verbally and that there wasn't any background music. Just the sound of the machines sublime!
Johnnyq90 is another channel you may like as well then
Fantastic planning, design and manufacturing skills - well done.
I started my apprenticeship in 1978 and you brought memories flooding back when you used the Engineers Blue for marking out - I had forgotten that stuff !
Great job !
still remember the smell of eng blue... the bigger challenge was manually scraping a flat-pate. We just a sharpie now
You must be very. Senior now sir
If you had started building that when you did your apprenticeship you might have finished it by now lol
This really blew my mind away. Amazing application of engineering, design & craftmanship. Making stuff at this scaly requires some scary pinpoint accuracy. Super cool !!
There's a joy in my heart I can't describe with words when I see someone do something like this for the sake of doing it.
I've seen quite a lot of miniature engines including some radials up close and personal. Made by guys/gals that have an arsenal of machines to fabricate them, But I have to say the precision and accuracy, let a lone the design, that you've done with a Sherline is the most impressive build I've seen in my old age. I enjoyed the build videos but this compilations is an inspiration in machining and videography! Thanks very Much for the ride and hope you continue to test yourself with projects like these!! Hat Tip ~PJ
That's quite a compliment! Glad you enjoyed it.
When you first began to turn it over I realized I had actually slid forward and was literally sitting on the edge of my seat. When it started I actually cheered out loud. Fantastic work!! 🏆
I kinda did too 😂
Sarcastic
The sheer accuracy of the design and the making of each component is very entertaining to watch. Final product was awesome. Reminds me of how scared I am about making something cuz of low accuracy haha. Really great stuff tho never disappoint 👍
If your designing something like this, id go with the smallest screw you be comfortable with tapping and available at home depot.... for me that be either 10-32 or 10-24 making this engine be a bit bigger, thus increasing clearance sizes a bit
I'm no machinist, but it's easy to tell you know exactly what you're doing right down to the spec. That was a beautiful build, bravo sir.
This was so satisfying to watch, I was immersed the whole time, and when it fired up, I had the biggest smile on my face.
Faith in the algorithm restored.
Thank you!
Glad you liked it!
Awesome !!! :)
Now please 'fix' 2-stroke motorbike engines so I don't have to buy a crappy 4-stroke 125 cc , cos 'Climate Change BS'...!!! :) Cheers !!! :)
What is 1000 hours ? 15 min is the video, but Idk what 1000 hours.
@@fynkozari9271 Im pretty sure it is the amount of time taken to fabricate/machine out all of those components
Impressive! In scale, accuracy and probably in lots of ways I'm too ignorant to appreciate, this is impressive!
All a person can say is, "Wow!". You are a very talented machinist.
This is one of the most impressive things I've ever seen in my entire life. Well done.
That's quite a compliment! Glad you enjoyed it.
Excellent work. It looks like the piston gained an o-ring by the time you assembled it ;) What type of o-ring is that? Does it hold up?
I was watching ur videos a minute ago and now I find you here, thanks for your videos
Yoo whatsup man
fancy seeing you here. you should try a project like this, would love to see how you go about it with all of the tooling and machinery that you have access to
Oh my gosh your channel is the best
@@baylornorris but how could he troll Wife Made Here with an engine? Actually, forget I asked - Shane would find a way.
Wer mit solchen Heimwerkermaschinen so genau Teile bearbeiten kann, hat echt was drauf, weil man zum eigentlichen Aufwand noch die Macken und Abweichungen der Maschinen "kompensieren" muss, was dann allgemein als Berufserfahrung bezeichnet wird. TipTop!
This is now one of my all-time favorite videos. 😭❤️👍🏼
It's so comfy to watch. The craftsmanship is amazing.
Wow, thank you!
Unlike every other video I've seen, this is literally the most productive video and time was used very wisely on this engine. I've seen videos of people doing dumb stuff and TRYING to "invent" things we will never do or use a single day in our lives. This video just taught me that there really are talented people out there that are actually productive! Very rare to find people like you! I'll give you a 100 out of 10.
Over all, this engine was fine crafted with precision, and a very clean engine, clean cuts on every component. You must be the most talented person I've seen a video on.
This is amazing! It's crazy how they designed and built motors without CAD back in the day
They used PAD ( paper aided design
@@theltcrowe9000 👍🗒️✏️📝📐📏🔧⚙️
CAD is entirely based on old school machining and design principals. They just drew all this stuff by hand lol
I took a couple drafting courses back in high school. They teach the basics with traditional hand drawn work before moving on to the cad software.
@@matthewdilger6755 That's the sign of a good school. Not every machinist will have access to CAD, and the fundamentals are always going to be there when the computer isn't!
The precision of everything from design to the end product of the engine (along with the editing and video shooting as well) was so nice 💯💯. This is going into the record books, and I hope that upcoming generations of engineers watch this and get inspired. Thanks a lot 💯😇
That's quite a compliment! Glad you enjoyed it.
Hard to comprehend that one person can have the engine design and machining skills that you have. Amazing project!
The average person can't even spell carburetor, let alone make one from scratch.
The amount of knowledge you must have to create on this level is never appreciated on the scale it deserves.
So cool.
本当にすごい！
男心をくすぐられワクワクしながら見てました。
You made an entire, working engine! This is beyond anything one would ever expect to see on RUclips. This is beyond outstanding even. It's a wonder.
How did you think the first engines were built.
@@Intelwinsbigly Like this. But it's so teeny. And it's so something that I could never do. My point was that some people are so talented.
@@tracybowling97 Beyond anything one would expect to see on RUclips? You know we have rockets that travel to space? Other miniature more impressive engines? Basically anything.
@@genogeno7289 ugh! Can't I leave a fucking comment? I like what I said. I know what I said. And I stand beside it. I just meant, ppl can do lots of things. And you get to see so much on RUclips. Much more than I ever expected to see.
You might like 54Garage, that guy does some really interesting stuff, like cutting an engine in half and getting it running.
The amount of precision, and how beautifully it runs is amazing.
No music, no voice narration. Perfect video.
Most people don't realize how hard even the 3d drawing part is. Amazing work!
Thank you for sharing something as amazing as this with us. I know absolutely nothing about engines, or mechanical engineering at all, but I appreciate that you decided to show us this. Can't even begin to imagine the amount of work that went into this.
I'm tipping 1000 hours worth.
That's the lovely thing about it though... it's made out of stuff that anyone can understand. No computers, no quantum mechanics, just pieces of metal moving in circles and back and forth to push things around.
This is not engineering. This is art. Truly amazing work
Engineering is art, my friend!
All that anticipation, and he never opened the throttle to hear it scream. Still great piece of mechanical art.
Fantastic work! One of the best DIY engines I've ever seen. My only disappointment was that you didn't open the throttle a bit when it was running. I'd love to se it rev!!
no
You know you’ve got some serious talent when you have a 15+ minute video and not one word is spoken and I watched the whole thing.
Agree, 100%
Agreed
Wow that thing is a piece of art i mean imagine how tight tolerances does a engine like such need to work and this guy achived that in his home shop with commercially available machines 🤯🤯

So amazing. I could watch these types of videos over and over. So much talent. I know the engine is not a new thing but to watch people craft the parts out of blocks of metal stock just amazes me. It takes a lot of talent and know how and patience. Great work. Certainly enjoyed the video.
Big thank you for watching this video
I'm a doctor and I think I'm pretty cool...but you are MUCH cooler. I forget that there are people in this world with those kinds of skill and brains. Amazing.
That looks like a labour of love. Very impressed by your skills and equipment. I can see why those mini gas engines cost so much now.
I hope they aint handmade or it will cost over 100k than😂
Gotta be a good feeling to make your own motor, extremely impressive.
i was thinking its a beautiful model and had my doubts it would actually take the force of combustion, even at small scale, but then you showed it running. completely blew me away with that. amazing. absolutely amazing

i'm still convinced the combustion engine is one of mankind's most impressive engineering feats, second to nuclear fission.
How about computers?
It's certainly one of the most important ones. Modern society would look a lot different without the use of internal combustion engines.
Pretty much the entire economy runs on engines
Think the order is incorrect.
@@jimmydcricket5893 so you think combustion is mankind's most impressive feat? Could you explain?
Seeing that little cam shaft spin true was probably the most amazing thing I've seen
That was strangely satisfying, well done very well done.
Truly a masterpiece. I may have missed something but I don't recall seeing any lubrication or oil in the crankcase.
I know you’re fresh off of that huge project, but have you considered making a driveline and everything? You could build your own functional mini car and maybe make it remote control. Just a thought/suggestion :)
Actually it was a very small project
Einfach nur wunderbar und genial! Ich habe zu ddr-Zeiten den Beruf des Zerspanungsfacharbeiters (heute Industriemechaniker) erlernt. Ich weiß wie die verschiedenen Metalle riechen und schmecken, wie sie bei der Bearbeitung klingen und wie schön es ist, am Ende das fertige Werkstück zu betrachten! Aber Deine Arbeit geht ja weit darüber hinaus! Selbst konstruiert, die Materialauswahl getroffen, Recherche usw. usw. ! Dir bei der Herstellung dieses kleinen Kunstwerks zuzuschauen, das war für mich ein wahrer Genuß! Vielen Dank!

Impressive skill and amazing result! I have done a couple of courses that included machining and both had a year project, one being just a vice and the other being a simple pneumatic gripper.

I cannot wrap my head around how you machined the cams. Whatever you did there, they came out great!
You can see it in details here, in the second half of the video:

経験上エンジンのパーツに要求される精度はなんとなくわかる。何が言いたいかというと1000時間で作れるのは天才すぎる。
I'm sure this engine would last a lot longer than most 2-stroke R/C engines. A 4-stroke this small is impressive.
No bearings on the connecting rod. It might wear very fast when under load.
@@Rudy97 You could make them though. There's already 4-stroke engine kits out there you can buy, that have connecting rods, etc. Pretty spendy, but well worth it for an R/C enthusiast.
@@Rudy97 nobody seems to have missed the little detail regarding the material used for making the crankshaft. It’s ALUMINUM! A plain bearing conrod is perfectly fine if it bears against a hard, polished surface but that aluminum crank won’t last long at all. It’s probably why the time spent demonstrating the engine operating was so short - probably seized or lost power in short order. I’m guessing that the Sherline lathe was not rigid enough to handle the stresses needed to accurately machine a steel crank. #MakerB, what’s the true answer?
I wish you would show it running longer and throttling up or down. Amazing work.
Yeah, no throttling :(
After watching this short video I instantly subscribed! Aside from being fortunate enough to have all this amazing equipment at your disposal, you are extremely gifted and talented! This is absolutely brilliant work! I wish I was half as gifted as you man!
Thank you!!
@@MakerB I only have two questions. First, did you design/engineer the engine yourself? Second, why do you not have more videos like this for me to watch man?! Lol...
Dude this thing is running insanely smooth!
Thank you!!
That is awesome. I can't wait for my machining courses, stuff like this inspires me!
It's time to upgrade to some larger, stiffer machines! Used Tormachs are very affordable, and will save you tons of time, let you use more steel / stainless / titanium, and give you better surface finish. It's no Haas, but it's a very affordable and significant step up.
I totally agree with you👍
@@MakerB but it goes without saying that you've accomplished some amazing things with the machines you've got! In what part of the world do you live?
@@ZPositive US
@Zeb they can't do stainless steels or titanium, which require a minimum horsepower and rigidity. Yes, you can whisper cut mild steel and get the job done with poor surface finish. But try that on 316 or titanium, and all you'll get is work hardening, chatter, and broken tools.
@Zeb wow, color me surprised! I now have bigger machines, and I guess I forgot how much trouble I used to go through just to make things work. I would never hoe that row on a Sherline today, but I guess where there's a will, there's a way!
That was freaking awesome. You made an engine few people could do. It's a beautiful little machine. That's quite an accomplishment.
Sounds like a Briggs and Stratton. Amazing work.
I got goosebumps when I heard the first cycle complete🤯 It is an absolute pleasure to know that there are thousands of students out there learning from your videos. DIY kits for apprenticeships would be an idea if it were economically viable to you or pairing up with melscience, kiwico etc. But thank you, even if you just carry on doing it for fun. Cheers!
That's quite a compliment! Glad you enjoyed it.
Just.. WOW !
Shouldn't you be opening packages from China!? :-P
I can't imagine how ecstatic it must've felt to get that running.
Awesome, it took like 10 seconds of watching a jet needle being made to work out how accelleration works on a practical level - that's mega! Thanks!
amazing job! I'm not sure what's greater, the mechanical talent it takes to accomplish this and have it work correctly, or the patience it takes to complete a project like this?!? Good work brother! I always love a flat top engine you never have to worry about valve float haha!
This is incredible. The design is amazing, the machining is amazing, and the editing is fantastic. I'm almost through watching, and I'm wondering - how is timing and ignition done? how is it lubricated? did you also manufacture miniature piston rings? is it a steel liner in an aluminum block w/ aluminum piston? (appears to be) how is the fuel source done? Fantastic work between the mini lathe and cnc mill, especially about the crazy jig to cut the cam.
Its a 2 stroke right? So there is something on the crank that senses when to send a spark.(usually this would be prt of the engine but hes using a seperate machine) Its lubricated via oil in the fuel, the suction of the motor pulls air through the carb and a little bit of fuel with it
And omg is it actually a 4 stroke
I think he put oil in it but he don't show that. Without oil the stop after a very short time.
This is so incredible and beautiful, I wish to be able to make a motor in the future like this one!
It's brilliant, so amazing. This must be one of what almost all machine engineering students dreamed. Really cute😮
Glad you liked it!
The cam shaft part had to be most annoying to get right. Did you manage to design it correct in software? With simulations I guess its easier now but still hard to put into physical. Oh and I sat and watched whole video without blinking I think. Thanks for the work!
Yeah can someone explain to me what was going on in that part of the video. How was the jig working to help get that shape?
This is one of the coolest videos I’ve ever watched! I wish i had the tools and the know how!
Absolutely amazing, impressive work. Thank you for sharing your skills with us.
This would be a great desk ornament, a work of art . I would buy one in a heartbeat
