Sorry about the audio glitches in this one, I watched the video through in the editing software and it was totally fine, the glitches happened in the final render. apparently this is a known issue with the software that i use, go figure. i'll fix it for the next one.
thank you. good to know my computer isn't having a stroke.
i was gonna mention it but you already got this under control and BTW absolutely fantastic build
Beautiful work👍🇬🇧
Dont sweat the petty things .... your voice is great and the Narrration makes sense and is appealing. You are dong great ... Subbed .
I am so glad you posted this. It was driving me crazy thinking my graphics card was finally giving up the ghost. 😓
Sorry that happened. Very enjoyable build and video otherwise.
So, it took you three days to get the engine started? When I was 13, in 1968, I was gifted a 0.1 cc engine, the Thimble Drone model, very similar to this one. The user manual said to turn the carburator valve screw about 2 or 2½ turns. It took me two years to get the engine started, when, out of desperation, I systematically tried all the valve positions in increments of ¼ turns. It finally started when the count was 12½ turns.
wowzers that must've been so many attempts!
If it was the Cox 0.049 with the aluminum fuel tank/engine mount they had a bad habit of gumming up the needle valve and fuel-line pickup from old Cox fuel. The best way to deal with it was to backflush the needle valve by taking a fuel syringe with a bit of silicone fuel-line on the nozzle, remove the spring and needle valve and give it a healthy squirt down the threaded hole the needle valve lives inside. better than taking the whole tank apart just to flush the gunk out. You also need to annually take the tank back-plate off and clean the old gum and crud from the bottom of their tanks.
@@tauncfester3022 Yes, it was that type of engine. And I had to build the fuel myself, which ended up being very expensive because of the ricine oil in the mixture, that I got from a pharmacy (my country had nearly no model shops those days).
I lost interest in diesel engines when I bought one in my youth, (I forget the make, - it was 50 years ago lol), and ran it in, mounted in a vice attached to a wooden stool. I left it running and it was sounding sweet, - too sweet..., it overturned the stool and snapped the crankshaft..😩 Just a dumb mistake, but to a 15 year old, ....devastation.
@@Demotricus The Thimble Drone wasn't a Diesel engine.
The smallest engine I ran was the Cox .020 but mostly the .049.
I developed a method of starting that used a hypodermic needle and syringe full of fuel. I could get them to run on fuel squirted from the needle into the exhaust port and then adjust the needle vale until I got the mixture correct. They would just scream. Lots of fun for a 13 year old. I am 81 now. Great memories.
EXCELLENT workmanship, Sir!
I still have an .049. I also have a .15, both aircraft engines. I have a .25 RC car engine.
Cox also made an 0.010 engine. It was used as a tie clip in a picture I saw.
I remember those TOO well !! That needle valve is VERY CLOSE to the propeller though !! Bit my fingers many times ! 😂😂
Cox made a dune buggy with an 049 engine. It was a pretty forgiving engine and similar to the model aircraft engine. My dad and I modified it for R/C using a Heathkit 5 channel digital propo system on 27.095 MHz which we built from kit. We only needed two servos for throttle and steering. That was a lot of fun to rod around on the street. Those were the days of messy castor oil fuel, no. 6 igniter batteries and large electronics. Now everything is small, Wi-Fi and electric propulsion, often with a first person view camera on board. A lot changes in 54 years. When we first started model making the single channel receivers still used vacuum tubes controlling rubber band driven escapements.
If I only had the machining skills shown in this video…
I owned the TD "0.010 which was considered the smallest American production model engine. One of the neater models I flew with it was a Monowing, freeflight "helicopter" that was like a powered maple seed. It actually flew under power well, but would plummet like a rock when the engine quit.
Do I have any of these machines? No.
Do I have any plans to acquire any of these machines? No.
Do I even have any knowledge of how to machine these things? Definitely not.
Did I invest 32 minutes of my life to watch someone make one of the tiniest engines I've ever seen anyway? Absolutely.
Great video, man.
Agree, but the 2. machines tool looks like not properly centered.
I totally agree, a wonderful video. This guy is an absolute genius!
You can start machining with wood :)
@@Splarkszter an engine wouldnt work made out of wood
@@thatwierdbilly What does that have to do with learning to use a tool?
My father-in-law was a turner, he made some of the biggest threads and machine parts I have seen. He told of huge lathes he worked with in his apprenticeship and he also marveled at watchmakers who worked with the tiny. Watching this brought tears to my eyes for the friend and mentor who passed near 40 years ago. Thank you, it was beautiful to watch.
Much respect to you, for your respect of your mentor. I hope you were able to pay it forward.
Wow, this took me back. I'm 75 and as a teen in the 60s I used to fly control line planes with an engine like this. Here in Australia the popular engine was the Taipan and all I could afford was their 1.5cc model. It looked very similar to yours here, and was their smallest I think and enough for about 20 inch wingspan plane. When I left home for university my mother emptied out my room and everything disappeared. Some days I'd just start the engine for the pleasure of seeing it run. As an old bloke I'd probably do the same now. 👍
I take mine out and run them about every other week lol.
Thanks for sharing!
I'm 76 and I too had a Taipan in Australia. It was 2.5cc. My fuel mix was equal parts of castor oil, kerosene and ether. Later I had a much smaller diesel engine I used on a free flight. My glow plug engines ran on castor oil and Shell "racing A" fuel ordered specially from the servo. My best engine was an Enya 5cc "3B super typhoon". It lapped competitors 6 laps to their 5 laps in the team race competitions. Fun times. Sorry your Mum junked your stuff, they just don't get it.
Aeroplane were out of my reach and Radio Control was something only the local Doctor could afford ... So we bout a sawmp boat out of fence palings and sheet tin ... And axe handle for the engine mount ...the 1.5 cc desal I was given by one of the older boys was damn near impossible to start since it had no compresssion left .. But it didnt sink and went like stink scared the ducks big time .... Probably some still in Trauma Councilling in Traralgon VIC ~quack~ .. Cheers MAte ..
On Ebay, I bought two OS Max engines a few years ago to relive my youth, both had the same typical 2 stroke problem, get them warm and the cylinder expands too much and there is not enough compression to create a vacuum in the crankshaft area,too much blow by, only restart when cold [had same problem with a BSA Bantam], tried to turn up a new piston but I think the bore is not true enough, am going to try and true the bore but doubt the accuracy of my tired old WW2 lathe.
@@adoreslaurel A BSA Bantam was the first motorised ride i ever did solo .... along a beach ..I was 13 ...
I once glued two popsicle sticks together! That anyone has this talent is really impressive to me!
HAHHAAHA!!!
I'm a retired machinist, I used to machine large 18' dia x 36'' Chilled Iron mill 1,800 lbs. rolls. I say this because I've always been fascinated by how small intricate machining was accomplished. I was hoping though that you can call out more specs on such things as the interference fit and tolerances for cylinder bore and piston fit etc. to fully appreciate the precision of your craft. It was a real joy to watch all your steps, thank you for sharing.
I love that within our industry there is such a divide between micro and large format machining. When I have to use a 1/16 drill I pucker but I know that’s huge for many machinists.
What seems to be missing from this video was the careful measurements of the parts as they were machined to exact specs.
Considering the tolerances for interference fits on larger stuff than what he does, I’d guess it’s somewhere near .0001 to .0005. I would certainly like to know the tolerances as well.
presumably the tolerances were as good as he could get them 😂
I simply watched this out of fascination - and it was certainly that! I had a work colleague (we were both aviators) who built scale model steam engines. Not only did they run (on meths IIRC) but they were gorgeous to look at too because the detail was incredible. His model of the Mallard was a work of art.
Male jewellery - as a modeller - and retired mechanical engineer - this video really is a masterclass in what is possible with the correct skill. Superb. 👍
Back in the late 80's - early 90's, as an apprentice toolmaker, I made this exact same engine from the model engineer magazine. I had skills gaps in my EITB log book (for those in the UK old enough to remember those) and used the manufacture of the engine to cover the gaps. Also enjoyed making it as well and still have it today. Great to see it on video 👍
I was introduced to small "diesel" motors like this one when I was about 7 years old. The kid next door turned up with a 1.5cc Frog diesel. We made some fuel (ether, castor oil and kero) and eventually managed to get it running. I have been flying model aircraft ever since and am now about 75 years old. Your skills with metal are way beyond mine but I still like to play with small motors. Thank-you. Mike in Oz
I buggered up my fingers starting Cox .049 engines beginning about age 9 and my parents never said a word about it. About a year later, I started building go-karts and mini bikes with Briggs & Stratton engines that we assembled from discarded parts from a local lawn mower repair business. We got shocked on spark plugs, burned on exhaust pipes, and ran into traffic because we couldn’t afford clutches and we didn’t bother with brakes. Kids are so protected that they will never know the sense of accomplishment that we had building things from the junk we found. Looking at a computer screen all day long is a poor substitute for the life kids used to have.
Haha yehe we went to forest building tree houses,, throwing stick at each other climbing tree falling and failing
Lol, how did you drive without a clutch?
I swear that the two of you above are my brothers from another mother! My two brothers and myself did the same exact things. Back in the day, when the cops would catch us on our mini bikes, they would just load them in the trunk and drive us to our parents house telling us to stop doing it. Next day it would be the same thing over again. We had more fun playing street football with all of the neighborhood kids with my dad playing along with us. He used to play college football and he would coach us too. Kids today are missing so much fun like we used to experience. It’s a sad world out there with all of the juvenile delinquents getting into trouble. Bless the two of you for bringing back some great memories!
i love reading this comment and checking off each item as i also experienced the same things. still have my briggs n stratton go kart with the fully burned out drum brake pads lol my nephew wanted it but i told him it wasn't safe.... am i part of the problem?... maybe i gotta give it to him anyway
@@AA-iq6ev i had a pickel jar full of nails in my backpack with a hammer and saw at school because me and a buddy were building a tree house after. when i put my bag on the ground on the concrete and heard *POP* i knew i chose the wrong container. i found pieces of glass in there as long as i had that backpack
At the vocational school I attended, where I majored in mechanics, there were lathes and milling machines. One of the students in the class above me made a piston for his aircraft engine (assisted by the teacher). He then installed the new piston and started the engine. I was very impressed with the accuracy of his work.
I watched your video on creating an engine from scratch. Man, you are talented! 👍
It never ceases to amaze me how these machinists know just where to remove metal from a bigger block to find the part that they needed inside. They must have X-ray vision to be able to tell which block of metal contains their part inside. My hat is off to them!
All kidding aside, when he first started with the lathe, I thought that it was much bigger until his hand entered the frame and gave the picture context and perspective.
Очень подробная и интересная работа. В видео такого формата раньше не хватало обзора детали, которую изготавливают. Спасибо за ваш труд!
If there was ever a design that needs to be made into a horizontally opposed engine, this is it. Changing the design in this way wouldn't just double the output and balance the forces but would make the machining far simpler, and give you a round crank. A single carburetor would feed both chambers as well.
Im a producer as a hobby, but welder/blacksmith as a job and this level of craftmanship makes me so absolutely happy! well done!!
This video brings back so many great memories for me. My late father in law (a partially-sighted master toolmaker and engineer) built this engine after seeing it in Model Engineer. I believe it was called as a Nano Engine?
However, Dennis (in his late 70s) built it at half scale! Finished size was around 3/4" long, including the propeller hub, if I remember correctly. All turned and milled on machines he had designed and built himself.
According to his strobe, it ran at 20,000 rpm. 😁 It certainly squealed.
I know I'm biased, but he was a mechanical genius. He once built a spark eroder (rather than buy one for £30k+). The first time he tested it, all the street lights within a mile radius dimmed. 😆 However, he could 'erode' any irregular shape he needed through 1/4" steel.
He also designed and built a working V6 engine which would fit inside a matchbox, and a very 'revolutionary' flywheel assembly. Imagine a flywheel with a driveshaft rotating at 45 degrees to the face, with a ball bearing end actually inside the flywheel, tracing a circular path, like a spoon stirring coffee. This was only two pieces of steel, and nobody could work out how he made it.
Thanks again for the video.
Very impressive!
In the 1970s, I finally convinced my father to buy me a Cox 0.010 engine (because it was the smallest and safest!) for my birthday. We got it recoil-started in a vise a few times on that day. The next day, I decided to start it while holding it in my hand, and did
Great story!😊
I did not grasp how small this engine actually was until you held that normal sized glow plug next to it. Holy cow that thing is tiny! Amazing work!
Tiny Two Stroke is my nickname
😂
I built a slightly larger engine but the piston fit was slightly tapered to make it nice and tight at the top of stroke. Fuel was U.S. diesel fuel, castor and "engine start" ether. Fresh ether for each run. Iron piston and steel cylinder. Crank to case fit was critical to stop compression leakage back to the carb and out the front. I used an electric starter, which causes the engine to warm as it spins over while adjusting the mixture and would start and run well. Running was extremely slimy. I used single transfer port and single exhaust port. My carb had an "o" ring and two clamping screws to seal it and hold it on. I've seen diesels with throttles that actually idle. Most of life is just showing up! Nice choice on Shureline.
Yep the mess was unbelievable but the smell of burnt Casteroil Mmmmmm yummy.
This brings me back, too. Back in the 1960s (I'm currently 68) I had the Cox .01 cubic inch motor, and it would spin a 3" prop at 27,000 rpm (advertised). A great little, reliable engine. I ran it many times. Sold it and a bunch of other small engines years later, and I've always regretted it. The .01 engine could have been used as a tie tack.
Oh, I still have an Enya .15 engine, but haven't run it in ages. Maybe as I approach retirement I'll have to get back into these.
i have a Cox .010 new in box....trying to decide which micro plane to build for it
I'd love to see your face when somebody tells you that you now have to register your RC airplane, with an N number. I mean, WTH?
@@MrJdsenior FWIW, I googled, "do you have to register a radio controlled airplane", and got this answer: "We're also required to have an FAA registration number that goes on any models we fly weighing over 0.55 pounds (250 grams)."
It's unlikely that a plane powered by a .010 motor will be more than a half pound. But still, I bet some .049 planes would have to be registered.
@@gregmead2967 Yup, my 100" RC sailplane goes way over that weight reqmnt, and it has no motor. ;-) I was so disgusted when I heard that I considered just throwing my planes in the trash, and selling the motors. The radios are so far out of date as to be unusable, anyway.
I know the RC community was pretty pissed about it and petitioned for an exception, which apparently never happened. It occurred from all the brain dead idiots flying drones where they shouldn't be, like air traffic altitudes around airports, WAYYY out of sight range, etc.
I think this is an amazing video and some incredible craftsmanship! One thing to consider is your fuel ratio to air and compression. If you don’t have enough compression and have too much ether it will stall the engine out. You have to calculate your fuel-air-compression ratio correctly or it’ll never run like it’s supposed to. To your credit though, the fact that it even ran was pretty amazing.
Now make a airplane using that engine
Yup
I , admire them super skilled machinist !!! I have an 80 y.o. friend that worked all of his life as a machinist !!! There is nothing more satisfying then watching a master at work !! Never needing to stop and think over his next cut !! 👍👍👍👍👍👍🇺🇲🇺🇲🇺🇲🇺🇲🇺🇲
Thank you for posting. I still have a disorted fingernail from injury sustained hand starting my ED BEE 1cc model engine in 1965. Enjoy your life folks, even if you live to old age it goes so quickly!
I was a biomedicall technician for 12 years glorified, machinist. I used some of the smaller machines you have to very large CNC milling and lathes. I also weld, Do heat treating and andizing Injection molding I even did some seamstress work. I did some tool and model making. A lot of skill sets that I don't have time and i'm sure you don't wanna read about. That being said I'm very impressed with your skill sets!! Yes , it was very satisfying watching your work.
Whatever filming setup you're using for the lathe is perfect.
I had a similar engine for a model airplane. It had a spring load for starting. Without that I remember the bruising on my fingers after hitting the prop a thousand times to get it running. It worked perfect once started and would rev and whine like a mosquito. Sadly a mate of mine decided without my permission to take it apart and copy the components to make one. In doing so he broke the brass fueling part and simply handed it back to me in pieces. Thanks !
I normally watch Cutting edge engineering Australia, this channel is like a miniature version of it. Takes Great skill to engineer those miniature parts in a miniature lathe.👍🇬🇧
The video is just very great. Its not loud its relaxing and the humor is that little mistakes in the editing.
i think it's definitely creating intake vacuum from the carburetor not being seated inside. maybe find a rubber hose you could fit in there snug with a tiny bit of RTV or loctite and run the carburetor through the hose
Who came here to see a flying pencil ?
Niiiice! I've built these and to get them to run, first take a small blowtorch and heat the cylinder head carefully. Get it good and hot, prime and start!
I like your "anti-license strike countermeasures" during the engine assembly (with music) against YT. I hate YT for that! Amazing workmanship and machining work. Sorry this engine didn't run better. As a young child, I did mess with Cox 0.049 model airplane engines. My planes never flew well, but the engines ran. I remember they were very fussy to get running, and now that you mention the ambient air temperature, I never thought about the Chicago weather temperature difference affecting the running of the engine during the summer. I might just have. That was a long time ago...
Yes very very fussy! I spent more time starting the engine than frying my model 😅😂
Having had an early interest in airplanes when I was in my preteens, but got tired of hunting for, climbing trees and rebuilding(more like total refurbished). I drifted toward model boats. Some hydrofoil, some to scale. But my passion was steam tugs. I still have packed away my unused Unimat latte/milling machine, that I turned out a Krick two cylinder copy with a boiler(original). All of this was in a NY harbor tug. During a show/ competition, some a-hole dropped and busted up about 8 weeks worth of build time. I pulled the engine, boiler, electronics and sold my collection on the spot!
I must say that your video sparked a challenge for me to try, but more than likely won't. My last plane was a turbo powered F4, which I so cleverly used to plow more ground than a Kansas wheat farmer! I decided to switch to something easier to retrieve. Thank you for your video.
this should have 1 million views!

I've never been so captivated by a master Machinist, or any other engineered Contraption in my entire life . I'm a machinist myself and cannot get over the technique and dedication to this project.
I become speechless when i watch you guys manufacture things like impossible.. i would consider you a national wealth!! I can build a country with an economy if i would have you
Coming into this with a CAD mindset really makes me appreciate the craftsmanship of taking a block and finding the shape on such a small scale!
Geeze, that brings back memories of the control line planes with the Cox .049 engine. 👍
Yes! I can just about smell that fuel burning from my dad's control line planes.
Cox engine were super easy to start.
I returned 8 testors brand engines in 1 day, none of them ever fired once.

The positioning of the propeller and piston is very important. You have set the piston "ZZ", the piston is at the lowest position and the propeller is horizontal. The propeller is a flywheel and has a very important role in starting and operating the self-ignition model engine on ETER. The mixture for running in the engine is 50% ETER, 25% kerosene, 25% engine oil, run in the engine at low speed and pause every 2 minutes to cool down. Once the engine has been run in and adjusted, use a mixture of ether 33%, kerosene 33%, engine oil 33%
WTHeck?! I just realized you are using a precision HAND operated lathe. Wow. I am blown away. You are master. OK, I see some operations are powered. Still. Wow.
only hand operated for threading, it's running under electric power otherwise. Thanks for watching!
Watchmaking skills!
If I hadn't been exposed to different levels of machining back in my working days, I'm not sure how your video would have struck me. The knowledge, patience and skill you possess is only matched by the enjoyment and surely the satisfaction this must provide. Before this video, I thought I have known some pretty damn good machinist.
The presentation and your delivery are a big part of the pleasure of watching today.
Thank you
Sir, you don't have two right hands but four. Respect from the Netherlands.
Ethanol raises the octane rating lowering the detonation point of the fuel the exact opposite of what you want for compression based ignition. I recall tearing down a .1 back in the 90s to give it a thorough cleaning and I used marv's mystery oil to reassemble it, upon giving it a spin it ran strong for 2 or 3 seconds which surprised me as I was not expecting it.
PLEASE call it the Teeny-Tiny Two Stroke! it rolls off the tongue so nicely, i just wanna keep saying it.
You are a genius.
100% going to use that when i redesign it smaller.
@@JellyFishMachineSMALLER!??
I could have the best machines money could buy and a fully fitted out workshop and would guarantee I couldn’t make this ( and I was a steel fabricator) . This is very impressive and a joy to watch 👍
Wow. I had a Cox .010 cubic inch engine as a kid. This is 61% the size. Well done.
i have one, new in the box
The Cox .010 works well to provide engine power to Gillows rubber powered aircraft kits. 🤓
The amount of skill in machining and engine building blows my mind!
As an owner of multiple Cox TeeDee 020 and 010's, some NIB, a few converted to 'diesel', but most in various drawers and storage boxes, I find this an impressive subject to attempt. Though honestly I'm much more interested in the last few seconds of your video mentioning a hope to attempt smaller. The 010's were a neat idea, and on the perfect day when the stars aligned could absolutely give a screaming and awesome performance in both sound and power, but in normal practice were 'fiddly' to the point of distraction. It was fun back in the day to spend the time to try to get one flying for the typical 2-3 minute flight, more to claim that it had been done than anything. I had a few friends into control line (and a few die hard FF) that were happy with their .020's, but, for R/C the more reliable .10 to .40's were really where the time honestly flying was spent. And, for those who could afford or were extra devoted, the .60 and up planes were a blast to watch and aspire to.
I would really love to see a build attempting smaller than .010 though, even though the power to weight ratio means it's somewhat pointless as a powerplant, it would be amazing to see a .0025 engine actually run. I assume the prop would be a 1.25" ? And probably 100k rpm at full song, in the dog whistle exhaust note range? Now THAT'S a challenge!
at 0.1 cc this is slightly smaller at .0061 cubic inches, a bit of unit conversion wierdness. as far as i know the smallest running model airplane ever made is ronald valentine's .006 cc "Nano Bee" but there's never been any proof or video of it running that i know of. I'm looking for a few copies of "Strictly I.C." magazine that have articles on making glow plugs from scratch. i also want to try spark ignition too.
Yes the sound of those engines when I finally got to start them!
A wrist watch powered by this would be crazy
As a Sherline owner I’m really enjoying your videos. Not sure if I’ve heard any commentary on your earlier videos but I do enjoy it.
I continue to be amazed at how good the sherline machines are! on the commentary, i wanted to wait until i got the filming and video editing part more or less figured out before adding another layer to it - doing voiceovers is actually quite challenging!
I had the COX .020 and .049 as a kid in the late 50's. At 76 I would have trouble as my machines are too big. Just making your tooling and wow the threading! I would love to see the plans and the tolerances they expected. Did you have to figure out your own machining sequences. Very nice work! And I did have a CO2 powered engine I never see anymore. 👍s@@JellyFishMachine
As a machinist I absolutely love your work.
Having been somebody that's worked with two-stroke racing for years you're on the right path as far as porting goes . The other thing is crankcase volume versus volume displacement behind the piston. The closer to 1:1 the better.
Just a headsup you're getting small enough that fluid dynamics of air may be changing going smaller.
this channel is underrated
Dude, you are a legend. I just wanted to let you know that.
It's the first time I see someone doing free hand with a metal lathe.
What a great piece of mechanical art!!!!
It was very entertaining to look, great respect for your mechanical craftsmanship. Thank you
Very impressive video, I enjoyed and appreciated your machining and fitting skills. Especially the freehand use with the cutting tools. I remember many years ago back in the 60’s my dad used diesel engines in model boats that he built. He used to mix his own fuel of 50% (vehicle) diesel and 50% ether, it always worked. His engines were commercially made engines and a lager size. However he did have a small one about the same size as yours, but was never able to get it running. Once again an excellent video well done.
omg that tiny little tool rest is so damn cute i cant even - i loved this video and I dont even do planes or engines or anything
I have very little machining experience and have a dinky little chinese mini lathe (which actually is quite nice for the $$$). I've already used the super glue trick - love it! In my case, to release the part, I put the part with the arbor in the freezer for a couple of hours, put a skillet on the stove, sat the part on the skillet after it was nice and hot, and let the uneven thermal expansion do its thing. It was quicker than soaking in acetone over night, but I still had to clean the residual super glue off the part.
Is it only me that gets sleppy watching this kind of videos? I swear it's so relaxing, kinda like ASMR and white noise ngl.
I had the Albon Bambi which has same capacity - the secret for running is just get the needle valve body - the bit with the hole in the side in the right place - it needs to be rotated so it is on the side in the airflow - it is critical. Also these baby motors need more oil than the larger ones. I had to make my own propellers out of ally - commercial ones did not exist in those days (1950's!).
Big respect! I‘m a machinist from Germany and you are skilled very well.
Good job!
Amazing,what a man can do!
Ahh!, the wonderful little Cox 010, I had great fun with mine back in the 50's, rudimentary R/C etc, it now resides in my souvenir cabinet, complete with a spare glow head in its little bubble pack, quite a conversation piece now.
Great video, nice machining, and great jazz.
Tremendous work man! Great to see the little Sherline used so well. Great camerawork as well.
Made the same for an engineering project at Uni. Still have the scar on my index finger from the prop when it finally kicked!! That was 40 years ago, good lord how the time has flown.
I have the machines, all the tools, materials and knowledge to build one of these. But I know I don't have the still fingers and precise dexterity, nor the eye sight, nor the patience to even start trying. That is Beautiful work, whether it ever really runs or not. WELL DONE.
21:55 Did I stutter?
Darpa may want to pick this up, refine it (albeit with or without your superb engineering) and make an extremely small IC engine for fixed wing drones.
This is what I want to do when I grow up 👍
Wow amazing machining. As a mechanical engineer in training with extremely novice machining capabilities this just amazes me!
I wonder how many have tried to make a 0.001 cc engine?
Something to power paper airplanes!😮
You are very talented and knowledgeable. I have just started trying to learn machining on a mini large. I might have been off more than I can chew. I'm starting to realize that machining the parts isn't the hard part. It's the set-up and preparation that has to be 100% on point. Well, looks like I'm watching a lot of videos and even more studying. I may ask a few questions while watching your videos.
how many watts does this make?
4.4 watts
I can barely get my dam lawnmower up and running. Hats off to this guy.
Now make a drone
I gave you a thumbs up within seconds of the start of the video, because you led with footage of the engine running. Many videos out there that want you to watch the making first. I prefer to see success first, because that validates the process, making the process more interesting.
Where do we get the plans?

The machining alone was worth it. Just lovely.
Engines as jewelry
Just finished watching your entire build video. Excellent work both in making the engine and in making the video production. Typical for a number of builders on youtube is to include in the video description the tools used and materials (especially the tools). Cheers.
1:23 metal cutter the platypus???
When I was a teen in the late 1970s a local drugstore, which by coincidence was also a hobby shop, had a "Going out of Business" sale. I picked up two Fox Combat Specials, Golden Bees, numerous .049 Tee Dees, and approx 3 .010s, and a ton of balsa plane kits, and Estes rockets. I sold the .010s quickly to some "free flight" old timers. They used a burning fuse to melt through a rubber band holding the throttle open after a set time to shut it down. I still have a couple of engines stashed in a box somewhere. I do miss being a kid.

Like many others here, I started out with the little cox .049 Babe Bee engines. Used to take one with me all over the place, fill the tank on the back, hold a battery onto the glow head, wind the spring starter back and let it rip while holding it in my hand 😅 Fun times, and fun little motor!
I love your little engine, thanks!
When I was a kid I was mad keen on model Diesels and Glo-Plugs. I lived in a remote area in Australia, so had trouble getting fuel, etc, until I learnt that the local Chemist (Pharmacist) would make it up for me. One day in desperation I discovered that my favorite engine would run just fine on two-stroke lawnmower fuel. I don't remember now if that was a diesel or a glow-plug engine.
If you can get Anhydrous Methanol in gallon quantities and if you have a local motorcycle supply house, Klotz makes a synthetic castor mix that is frequently used in real model engine fuel. I think it's called Benol.
Warning; Methanol is a poison and it's dangerously flammable.
25% oil to Methanol makes what is known world-wide as FAI model glow engine fuel. Also some pharmacies used to sell a 4 oz. bottle of Castor oil, but this was in the US.
It's my understanding that an engine that size would require a pressurized fuel system that would enable the engine to feed itself in the right mixture of fuel to air. It would also require some sort of minute mesh to spread the fuel as needed to the appropriate spray pattern for the cylinder you designed. I always enjoy watching mechanical machined engine videos. great job on that one :)
I'm glad you added voice over. It makes a difference to us ignoramuses.
Great workmanship. I would not have all that patience. A very precise work. Compliments.
Zerspanung ist doch etwas Tolles ! Toller Film mit erstklassigen Bildern !
SIMPLY AMAZING !!! WITH THAT ENGINE YOU CAN MAKE ANY MODEL PLANE SHAPE AT THAT SCALE. HAVING MACHINERY LIKE THAT THE SKY IS THE LIMIT !!
Amazing ❤
I remember using a K- Mills 0.25 cc "Diesel" (compression) engine as a teenager in India in the mid eighties and know how difficult it is to start these!
Absolutely awesome! The fact it ran at all is just amazing!
I don't fly RC aircraft. I don't have the means to make this engine. Was I fascinated by this build? Hell yeah! This is freakin awesome! 🫡🫡
I had a few cox engines as a kid and the sound of this brought back memories. I feel like the sound is very similar to the small cox engines.
Model Engineer was my dad's favorite magazine. (We still have boxes of them in the attic..). He was more into model steam engines and such whilst my hobby was R/C aircraft, this tiny diesel engine reminds me of my first purchase, a control line (plastic) aircraft powered by a Cox .049 cc Nitro Glo plug engine, (not the same engine but similarly tiny).
Happy memories..
