Latheman's crazy machines
Приєднався 3 бер 2012
Crazy little machines, cool scientific phenomenons, useful DIY tricks and cats.
Welcome to my channel!
This channel is mainly about model engineering. I show some of my Stirling engines, Manson engines, Vacuum engines (also known as flame-licker engines) ,Thermoacoustic engines, Nitinol Engines, ball bearing motors and how to build them.
I also show some interesting scientific phenomenons (about magnetism, Euler's disks, Marangoni-Effect ).
And I have some cat videos. 8-)

Cool Gyroscopic Training Tool
This is a Gyroscopic Training Tool that I made on my mini lathe out of bronze, brass and stainless steel. It's not a Gyroscope!
I just used a commercial Gyroscopic Training Tool and replaced every part of it step by step with the part that I made.
The commercial Gyroscopic Training Tool are sold under many names: eg. Dynabee, Powerball, GyroTwister, NSD Spinner, NSD Power, RollerBall, Bushido Ball, RotaDyn, Spin Ball, Timmi Ball, Twister Maxx or Gyro Exerciser.

My first 3D printed metal part
Переглядів 7 тис.5 років тому
This is my first 3D printed metal part. I designed it with Designsparc Mechanical (a free CAD program) and sent the STL files to Shapeways to produce it. The purpose of this metal part is to reenforce the connection of two wooden handrails in my brothers house. Surely over engineered for this purpose, but it was a good way to try out this technique.
Red hot glowing 16 Cylinder Stirling Engine
Переглядів 80 тис.5 років тому
Here I show a 16 Cylinder butan powered Stirling Engine that I ordered from china. Although it looks like an aircraft engine it is just a desktop toy. Stirling engines have a way to low power / weight ratio to be useful in (model) aviation applications. What makes it special is its unconventional swashplate design and its awesome jet engine look.
Unbelievable startup of a 2 Cylinder Stirling Engine
Переглядів 562 тис.5 років тому
Here I want to show you the awesome start up of of a 2 cylinder Ringbom Stirling engine. It's a Ringbom Stirling engine that I bought from AliExpress. A Ringbom engine is a Stirling engine where the displacer piston has no direct connection with the crankshaft. Instead it is moved by changes in the air pressure.
The Moonwalking Rings

Here are my magnetic magic rings. Because of their at first sight confusing and irritating motion, I called them the "Moonwalking Rings", a silly analogy to the famous dance move.
Desktop Stirling Model Airplane Engine
Переглядів 88 тис.5 років тому
This is a Ringbom Stirling engine that looks like a Nitro plane engine. It can't be used as a real model engine because it has a way too small power to weight ratio and of course the open flame would be blown out if you was used in the plane. It's a nice desktop toy that demonstrates the function of a Stirling engine.
Could this be refined to a phone charger?

Two Types of Impossibility

Here are my two impossible dovetails. I made them on a SIEG SX2 table mill out of brass and aluminium.
The Impossible Screw will drive you nuts.
Переглядів 684 тис.5 років тому
Welcome to my impossible screw. It's a small project you can do in your home shop even if you don't have a milling machine or lathe. A hacksaw and a file will do. It also makes a nice last minute present. If you try this I recommend to try it first with a brass screw. It's very important to deburr it carefully. Otherwise it will be locked in both directions. If you give this away I recommend to...
Huge Vacuum Engine with Glass Cylinder
Переглядів 8 тис.5 років тому
I bought this Vaccum Engine (aka flame-licker engine, flame-engine, flame-dancer) on Ebay. Although obviously produced commercially it didn't work. I adjusted the linkage of the engine, opened the intake from 6.5 to 9.5 mm and reduced the diameter of the piston slightly. After lubricating it with Molybdenum Disulfide (MoS2) powder it worked.
6 Cylinder Engine with Only 5 Moving Parts
Переглядів 20 тис.6 років тому
Here's an "Elbow Engine" that I made very loosely based on the plan in the July 1965 issue of Popular Mechanics and on Julius de Waal's plan that I found on a model engineering website. It is very simple but has to be machined very precisely. It's made out of brass, stainless steel, aluminium and delrin.

This is a very small Turner's Cube (an old machinist's exercise) that I made on the milling machine. I etched it after machining to remove the burrs and to give it a nice surface finish.
Super Hero V2 Stirling Engine
Переглядів 18 тис.7 років тому
This is a two cylinder Stirling engine that I bought on eBay. The two cylinder pairs are arranged in a V2 configuration. There are two things special about this engine: First, it looks like a superhero with huge muscles. Second, it has some very strange displacer pistons. They are not airtight cylinders but aluminum cups that are open on the hot side. In fact, they are no displacers at all sinc...
Walking Machine driven by Stirling Engine
Переглядів 12 тис.7 років тому
This is a nice toy I have ordered from AliExpress. It's a simple mechanism that moves on four "legs" and is driven by a hot air engine. I replaced the spirit burner by one I made myself because the wick of the original burner was too near to the glass tube and I added four Barbie shoes because the whole machine was not crazy enough. 8-)

Are these for sale? I’d love to buy one
Im not sure it is Dr Johnson. The mechanism you have is the same design as McDonnel Douglas developed in this video. The research is from 1982. It is the second prototype in the video. ua-cam.com/video/8-dCIkJAjyM/v-deo.html
hmmm... valve and piston driven/driving crank, possibly a bit of play and spring on the valve itself so it seats properly, with a disc sliding on the valve stem acting as a one way valve inside the cylinder. and it needs to hang upside down not only to meet the flame nicely but also keep the valve closed...
Pluto will always be a planet to me. Period.
You made a penny to stick to a magnet?
Thank you very much
And here i am still watching this everyday since the release 😊❤
You could also power it with a laser with necessary safety precautions.
Still don’t understand how this works?
flame and heat is hot and less dense air. suck in flame. close (visible) valve. flame/air in cylinder cools, densifies, reduces in pressure. atmosphere on the back of piston pushes piston up cylinder, as one way valve (under the valve you see) closes port and maintains low pressure in cylinder... piston descends again, sucking in a new flame past (barely visible) one way valve... repeat.
@@paradiselost9946 I got it, but the part I don’t quite understand is the ‘cooling’ of the air when the valve is closed. It’s only a second or two. Couldn’t be much cooling. Thanks
@@johnr5252 thats the issue... have to keep the cylinder cool. gets worse as size increases. not much surface area either. and as theres still air in there, its doesnt really have much drop in pressure... unlike steam... its a VERY inefficient "atmospheric" engine. which only have 14.7psi of atmospheric pressure producing force to start with...
@@paradiselost9946 thanks!
I'm almost 60. Since I was a kid I would look at diagrams of the solar system with all planets rotating on one disc and Pluto having an inclination in its orbit. And I always said something is WRONG here. When they said Pluto is not really a planet my life long question was answered once and for all. For me Pluto was always an enigma and never a planet. It just took scientists some time to see it.
Where can I find this model !!!!
You can see the magnetic field
it is NOT boring!
Built one in high school the teacher said wow
How did you austinze your wire, i got some and its undeformable. Its just straight and stiff.
god bless you...🤩🤩🤩
8 years wow
uneconomical
I came for the earts, but I stayed for the kitty
Ok, you create a stirling engine, great ! ! Please to can you go to the end and make electricity. How much watt do you produce ? Is it sufficiant to chargne the barrety of your phone ? Thank you
Very good shaw
Uzmi ping-pong lopticu i stavi je u vertikalnu struju vazduha. Loptica ostaje lebdeti iznad izvora strujanja vazduha, jer strujanje obuhvata sferu loptice i stvara se sferično simetrična razlika pritisaka usled opstrujavanja loptice (Bernuli!), dole veći a iznad niži pritisak. Rezultanta razlike pritisaka sa poprečnim presekom loptice daje dinamičku uzgonsku silu koja izjenačuje težinu loptice.... Jeli jasno? (nije na odmet i laicima znati malo aerodinamike!)

I don’t understand why the wheel stopped turning at the end since there was still heat difference available. Any thoughts?
No me funciona el motor😢

That's really amazing can you tell me where I can buy one thank you from Tacoma Washington
On Vibration removal purpose? Or, some incomplete helicopter rotor mechanism?
Such an underrated channel-

I'd absolutely love to buy one of these.
This is how turbines work? And planes don’t use fuel?

Hi. Where can i find the plan of this motor ? Regards.
They always love some oil, i use a thin engine oil in mine. For loooong runs

Can you get both the upper and lower magnets moving at the same time? Also what happens if a second field is present. 🙂
I built one of these about 6 years ago (no teflon, no springs). So close to running but never did. I suspect one or more of the three "pistons" is not a dead flat bend. Time to give it another shot. Also thinking of running the upper rotor on a shaft that goes through the upright block instead of the bolt. That way it can actually be used to power something.
Really nice job! I love that movie BTW. One of my all time favorites.
man you’ve just got yourself a one way ticket to the fbi watchlist
Wow beautiful engine
Que máquina linda.Genial . Parabéns 👏👏👏👍🙏🇧🇷
Excellent👍
Woow bro. Some serious skill here.
Amazing
