[@wafikiri_]

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.

[@pauls5745]

wowzers that must've been so many attempts!

[@tauncfester3022]

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.

[@wafikiri_]

@@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).

[@Demotricus]

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.

Much respect to you, for your respect of your mentor. I hope you were able to pay it forward.

[@rexmyers991]

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!

[@kevin34ct]

I still have an .049. I also have a .15, both aircraft engines. I have a .25 RC car engine.

[@terryvickers5986]

Cox also made an 0.010 engine. It was used as a tie clip in a picture I saw.

[@MikeMichaels-f5i]

I remember those TOO well !! That needle valve is VERY CLOSE to the propeller though !! Bit my fingers many times ! 😂😂

[@wtmayhew]

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…

[@tauncfester3022]

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.

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.

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!

[@iconoclad]

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.

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.

He used to play college football and he would coach us too. Kids today are missing so much fun like we used to experience.

Back in the late 80's - early 90's, as an apprentice toolmaker, I made this exact same engine from the model engineer magazine.

Also enjoyed making it as well and still have it today. Great to see it on video 👍

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.

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.

[@gregkretchmer3588]

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.

If there was ever a design that needs to be made into a horizontally opposed engine, this is it.

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.

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%

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!

[@JellyFishMachine]

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.

[@philfrydman2576]

Yes the sound of those engines when I finally got to start them!

[@badblenderanimations1449]

A wrist watch powered by this would be crazy

[@aprilliac]

Great video, nice machining, and great jazz.

[@devilsoffspring5519]

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!

[@AnIdiotOutdoors]

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! 🫡🫡

[@sladoled26]

Amazing,what a man can do!

[@mozkitolife5437]

The machining alone was worth it. Just lovely.

[@truedinis]

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.

[@rowdyriemer]

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.

[@alf3071]

how many watts does this make?

[@Brunt-yr4vw]

4.4 watts

[@patturk7408]

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.

[@staxter6]

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.

[@rickoshea8138]

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.

[@al_kaloid]

21:55 Did I stutter?

[@fivestar2227]

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.

[@dantyler6907]

I wonder how many have tried to make a 0.001 cc engine? Something to power paper airplanes!😮

[@jregns]

Wow, beautiful work! It threw me back to my teenage days (I'm 51 now) when I was hanging out with the "old men" (same age as me now 😅) at a nearby RC field, checking out their model planes with mainly OS MAX 15, 20 and 25 engines (2.5 - 4.0 cc) or Thunder Tiger equivalents. Sometimes, someone with a larger biplane and a 4-stroke would come by, or even a RC helicopter. Sweet memories! 🛩🚁 Greetings from Sweden!

[@GrandadTinkerer]

Where do we get the plans?

[@JellyFishMachine]

Plans are Here grabcad.com/library/gordon-nano-0-1cc-aero-engine-1

[@AbnormallyDisfigured]

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

[@haseeze1314]

1:23 metal cutter the platypus???

[@hpodell]

I remember tying a rag to an .049 and throwing that in the air. This engine. A very small rag. Great video. You have the patience of Job. Thanks for a fun watch.

[@allengentz7572]

[@kevinavillain4616]

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.

[@MrChampler83]

Big respect! I‘m a machinist from Germany and you are skilled very well. Good job!

[@Alexdacat8]

Now make a drone

[@Marvinfj32]

Great job, it reminds me of the patio bug zappers! Lots of patience. Never stop creating.

[@davidmerrittjacovino]

Engines as jewelry

[@gyrogearloose1345]

Tremendous work man! Great to see the little Sherline used so well. Great camerawork as well.

[@GroveDave]

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.

[@paulmaxwell8851]

I'm in central British Columbia, Canada. I got rid of almost all my childhood toys and things over the years, including all my model airplanes. But I did save my small engine collection. I have a McCoy Redhead .35, a Supertigre .29, an Allen Mercury 1.5 cc diesel, a Davies Charlton 1.0 cc diesel, several Cox engines such as an .020, some .049s and an .09, and a Fox .35 RC that I bought brand new when I was sixteen. I think I paid $35 for it at Ben Hill's Sporting Goods in Victoria, a lot of money for me at the time. It has only been run twice on a test stand. I miss those old days, and this is all I have left; not even one photo survived the years. Great video!

[@CaptK-py8rq]

I bought the Fox .35 new in the 60's, from the hobby shop, I still have it and the box, just checked the box, it was $11.99. The motor's still on my "Voodoo" wing I built, we flew combat and cut off the opponent's streamer. I had a few of the plastic U-controlled planes that came with the Cox .049, the PT-19 flight trainer, P-51 Mustang, Ju-87 or 88 Stuka that you could drop the red bomb, these were all less than $9.00 each! For the whole plane, motor and accessories! Used the Mistle Mist fuel. After the plastic ones I built the rest from balsa wood and paper.

[@JayZoop]

The amount of skill in machining and engine building blows my mind!

[@OgOssman]

I thought I'd seen everything, and then you started making your own micro drill bit... wow this is awesome, great work.

[@doncarnine]

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 :)

[@workingTchr]

I 3D print various utility parts and really enjoy it, but I have to admit, machining parts out metal is a dream.

[@yyyzzzz]

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.

[@r.hc-m7677]

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!).

[@zakilegrand4247]

C'est vraiment un travail précieux d'une haute précision. J'ai apprécié ce que tu avais fabriqué. 👍👍👍👍👍

[@steveperry1344]

when I was a boy back in the early 1960's I had cox .049, .020 and tiny .010 engines to power the planes I built from kits, both control line and free flight. we had a lot of fun with them, I can still smell the burning fuel, it had a very distinct odor.

[@WorldScott]

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.

[@Demotricus]

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..

[@ScottB-k7v]

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.

[@micahfoley9572]

the whole thing is remarkable, but mostly i'm amazed that he didn't lose that tiny plug and remembered where it was years later lol
