Having been a steam engineer most of my life, I am astonished. Truly impressive work. It may be the smallest steam engine on the planet. Call Guinness!
It very well might be. Btw that 'adapter' part is hilarious. It just shows how ridiculous the scale is, when the air feed tube is also the entire engine mount 😅

In the early 90's I read an article in (I believe) Model Aviation magazine about an elderly watchmaker immigrant in NYC who made a bunch of multi cylinder CO2 engines so small you could fit the collection inside a Contac capsule. The article included pictures or I wouldn't have believed it. A working 5 cylinder CO2 engine about 3 mm wide. I was never able to find anything about him on the internet.

@@CenReaper. There were nice clear pictures in the magazine. Although I may have the date wrong of when the machinist made them.

Lead would be doable, or some alloy of lead. Tungsten would be better, but I know it's notoriously hard to machine, so it might not be possible with his workshop.
@@akaHarvesteR It's used in jewlery, so no. It's no more toxic than platinum, which makes sense since it's one of the noble metals. However, like platinum, compounds containing it can be especially hazardous, such as it's oxides. Easily mitigated with simple galvanizing though.
I remember making one of those oscillating engines in school over 50 years ago as an introduction to machining, I really enjoyed the process ! You make it look fairly straightforward but it's difficult to get a sense of scale on a large screen, drilling the match head at the end put it into perspective nicely !

“This is the larger version my wife Hazel made several years ago” I’m lucky myself having a wife who shares and appreciates some of my interests but this just another level :)
Holy crap, that’s amazing! If you keep up like this, it won’t be long before people are telling Chris from Clickspring “That’s some Chronova level workmanship, mate!”
It’s mind blowing how small it is, amazing at the skill required but I was lost for words when you casually mentioned looking under an electron microscope! Wow, just wow! :)
I have a complaint. I made one of these and left it on my desk not thinking much about it, and then a bunch of ants came along and stole it. Now every single time I try to stop the ants from getting to my food, I get assaulted by an army of miniature WW1-styled vehicles (bi-planes included). Now, the weapons don't hurt, but I am afraid that they may target my eyes, and with how fast they're progressing (They stole my engine 5 days ago, as of writing), I'm afraid they may create rounds strong enough to penetrate my skin and injure me. While their vehicles are currently slow and fragile, and I can destroy them by stepping on them, the sheer number of these vehicles is getting me worried. As of now, the only weapon effective against a large group of them is pesticide, as they don't have gas masks, nor are their vehicles air tight, but I'm running out, and it's getting expensive. Please help.
I don't think it came through very clearly on video, but anyone who's held a 0.3 mm drill bit knows how incredibly tiny it is! I have one and I can't imagine how they are even produced...
I had to use 0.3 mm drill bits for some ceramic parts. The box that contained 10 of them fell off the microscope stand onto the table below while I was messing with some parts. Every single bit immediately snapped off when it hit the table. I stopped working for the rest of that day to cool off after that.
I would absolutely love to see u make a super tiny water boiler that can run this engine while being incredibly tiny, it could even end up in a watch or something as a proof of concept and because its cool, also I would love to see the efficiency of this engine

This is absolutely insane!!! I just saw a video that might interest you. It's this new tech of a silicone microchip that acts as an active cooling fan you can put into electronic devices. I definitely recommend you check it out. It kind of utilizes similar properties. The chip uses ultrasonic vibrations that's within a custom container with a unique seal that allows for moving hot air and cold air to circulate. Just thought it's a fascinating advancement in heat pump, cooling fan type technology.
Great video. With small scales, thin film application can help a lot to restore tolerances or to put finishes on items that improve the performance at a molecular level. You can thin film deposit inconel or nickasil and then 'polish' away to tolerances, giving you a bit more lee-way with machining things for final assembly.
This is absolutely amazing. I started working with aircraft engines almost 2 years ago and thought that our tolerance limits were insane, being +/- .0001” or less on con rod piston pin holes. But I can’t imagine the tolerance you work with here. And of course the scale of what you’re working with is astonishing. Great video, subscribed and look forward to seeing more
I am not an aircraft mechanic but are you sure you need to hit +/- a tenth? There would not be enough clearance for oil to flow. I am not sure what tolerances he is shooting for on this project but I think for port positioning +/-.001 would work fine. .3mm is about .012"
@ factory limit on continental rod piston pin bushings for the 470-550 engines is 1.1267”-1.1269” so yes, that’s a .0003” range, or 1.1268” +/- .0001”. The lycomings have a slightly larger factory limit, but we still have to get within a .0003” range per shop standard.
@ oh, and the pin that is going in that hole is definitely smaller, it’s probably 2-6 thousandths smaller, I haven’t measured them because I’m not assembling them yet, but the standard in the book doesn’t give you much room for error
You continue to astonish me with the scales you are able to work at! i'd live in mortal fear of sending one of those tiny pieces pinging across the desk!
Firstly, amazing work, thank you very much. And secondly, i love that you also show your failures and how you are overcoming them. Everybody is gonna fail, but you have to just accept it and move on. Failure is a huge part of success!! Whatever success means for different people. Thank you for that too!!
Love your little lathe...and your level of craftsmanship. I know what you mean about speed with small drills...although my smallest have been 1/64" (about .4mm)... but even they didn't really cut well under 30,000rpm. I made my own drill from a 12v slot racer car motor that freewheeling shows close to 50,000rpm on my tachometer. That speed put one of those tiny drills through a 2mm steel plate in just a few seconds... My source of such tiny drills in NZ no longer exists, but my need for such tiny holes is past now....that was all back in the 1960s. Perhaps a similar little engine of this kind might work for drilling? 🙂
I found that when using small carbide bits, you have to spin them as fast as possible and feed them into the part excruciatingly slow. Think about when you tense up your hand to do something extremely delicate; that's pretty much how you have to turn the handle of a manual mill. In industry, these bits are often used for printed circuit board manufacturing. The CNC routers they are used in often spin 100,000+ rpm to achieve normal feed rates. The chips they make are pretty much dust.
It’s not a steam engine until you put steam through it. I would love to see how it handles condensate in the cylinder. At that scale, surface tension and capillary forces will be quite significant.
Ik heb laatst precies zo'n zelfde stoommachintje gebouwd! Ongeveer zo groot als een lego minifiguur! Zo klein als u hebt gebouwd is ongelofelijk! Groetjes uit Nederland!😃👍🇳🇱

This stresses me out just watching it, there's not a chance in this world that I would even consider trying something like this.... Serious skill mate fair do's
Sick!! Now to build the thing this engine will power!! I want a watch makers lathe. Still looking for a cheap one. I have a full size lathe and mill but the smal small stuff is hard to do. Keep up the great videos!
For your micro holes: you could try using a shorter flute length drill as well. Carbide is stiff but can still flex, especially at that size. It looks like you are using circuit board carbide drills, they are cheap carbide but they also have a bad length to diameter ratio for rigidity at the cutting edge. They are also designed for use in a much softer material then steel so cutting geometry isn't going to be ideal either. I will be drilling a almost 200 of 400, 300, and 250 um holes in a few nozzles at work later this week. Wish me luck!

Copy milling was once used extensively in the production of precision dies. The process of iteratively machining a workpiece in a circular fashion is still often referred to as copy milling even though it's usually done with a CNC machine.
Very cool project!! Back in university there was this super cool project to build a piston engine the size of a grain of rice. Not sure whatever happened to that.
watch makers are the true mad scientists of the engineering world. kolibri pistol was an example. its not even just micro engineering, just art as well.
That is a great achevement with basic machining techniques, The slowing of the damped running is possibly due to the out of balance forces pressing the flywheel crankshaft hard against the bearing wall.
oh, that's a surprising amount of power! I think an interesting application would be to solve one of your earlier problems in making this - high speed microdrilling.

The heat of steam may tighten up some of the moving parts.
Copy milling was once used extensively in the production of precision dies. The process of iteratively machining a workpiece in a circular fashion is still often referred to as copy milling even though it's usually done with a CNC machine.

Very cool project!! Back in university there was this super cool project to build a piston engine the size of a grain of rice. Not sure whatever happened to that.
The question is... how much energy can you get out of it with some magnets and core wires?
watch makers are the true mad scientists of the engineering world. kolibri pistol was an example. its not even just micro engineering, just art as well.
Brilliant work! Subscribed!
Excellent all you need is the funky music and could episode of how it's made.subbed
That is a great achevement with basic machining techniques, The slowing of the damped running is possibly due to the out of balance forces pressing the flywheel crankshaft hard against the bearing wall.
Really nice job..
Thanks for taking the time to make the video and share
oh, that's a surprising amount of power! I think an interesting application would be to solve one of your earlier problems in making this - high speed microdrilling.
