- In this video I’m modifying and testing a 9 cylinder radial solenoid engine.
Here you can also see inside the crankcase as the engine is running.
I hope you enjoy this as much as I do!
Thank you for watching :)

Big thank you for watching this video :)
Please check out the making video. Part1 : czcams.com/video/JWPxP2uuCJ4/video.html
Have a great day :)
You should try heat treating the rounded cover to see if you can clear it up.
So it cost what?
How do you control power supply
U ONLY NEED TO BALANCE IT TO A SMOOTHER ROTATION.
Почему бы не сделать полноценную функциональную модель двигателя, а не его часть?
Next up: Flying a plane with a micro radial engine.
Flying a drone with radial engines!
@@aaronatherton7431 I'd watch that
So would i
Tom Stanton, take notes
This would probably be too inefficient or battery draining. But I’m down to see it
Maker B. The only person that would build a micro radial engine to cool his coffee.
You deserve that cup of coffee, great work! I’m subscribing!
Honestly?!
In terms of explaining, building and giving this to us, you are an ARTIST! THANK YOU MAN! 🍀👍😃🍾🌹💞
Love how it starts up kinda rough then smooths out. You'd think it was running on gas. Video is excellent.
thats what i thought as well^^
Its called a lope in diesel terminology. 💁🏼♂️
What a fantastic course on metal working techniques with a fun purpose in mind! On top of that, the inner workings of the engine mimic a real radial engine very closely on the principles of operation. Well done, sir!
Excellent presentation style! Thank you for putting thought and time in the making of this video for our enjoyment.
He has heard our pleas, and we are grateful to him
Hear, hear, Grom !
Airoplaneeeee
Ask for larger portions at lunch.
Absolutely.
Awesome 👏
Wow, just seeing the internals and only knowing its electrical pulses I now know exactly how this engine works! Very cool.
Incredible machine work and craftsmanship. The engineering and precision involved to produce such intricate parts is truly superb. Very enjoyable to watch an expert at work!
Thank you for the kind words!
Believe me, this guy has the video of highest quality ❤️❤️❤️😍
This is the coolest thing I've seen in a long time dude... when the whole world has gone to shit and it's all bad news this made my day.
Cheers
Glad you liked it :)
Hi Maker B,
I just watched your videos on the construction and modification of your 9 cylinder radial engine, so first off may I congratulate you on your workmanship, it is absolutely superlative and I have turned a strange shade of green with envy over your workshop.
I haven’t read all the comments, so forgive me if someone has already brought this up, but I may have a way of increasing the efficiency and power output. In your video you stated that the coils were being energized in numerical order starting with 1 at the top and then proceeding counterclockwise from the camera’s point of view to 2 then 3, 4, 5, 6, 7, 8 & 9 before starting the next cycle.
After you installed the clear crank case cover I noticed that by energizing the solenoids in sequence the amount of movement of the next solenoid’s piston (technically it is solenoid core, but piston sounds better) is fairly small. For example after energizing coil 1 you energize coil 2 which only pulls the piston a short distance and rotates the crank through 40°. However, if you look closely at the position of all the pistons you will find that coil 6’s piston is almost completely out of the coil. Unfortunately, while energizing coil 6 would drastically increase the comparative movement induced of the piston and by inference the crank it is more than 180° (200° to be precise) past the position of coil 1 and would cause the crank to try and rotate in the opposite direction. However, the piston of coil 5 is also almost extended fully and is 160° past coil 1. Therefore by energizing coil 5 instead of 2 it would produce a much greater movement in the piston which would result in the crank rotating through 160° instead of 40°.
If this sequence is extrapolated advancing the coil energization by 120° each step the sequence would be 1, 5, 9, 4, 8, 3, 7, 2, 5 and back to 1 producing 3 rotations of the crank instead of 1. Having said that trying to rotate the crank through 120° per coil energization may be too much so it might work better if only advance the energization order by 80° giving an energizing order of 1, 3, 5, 7, 9, 2, 4, 6, 8 then returning to 1, which serendipitously corresponds to the firing order in actual radial engines.
It shouldn’t be difficult to try as all you would need to do is either rewire wire the coils appropriately or if change the sequence by reprograming the microcontroller.
Great work,
masu
That was my exact thought since radial engines don’’t fire in numberical sequence. Thanks for asking! I’m looking forward to the answer.
Fun stuff. I was particularly fascinated by the way the whole crankcase flexed as this thing ran. Cool hobby you've got yourself there.
What a surprise the Shigley!! Magnificent book for mechanical design and widely used in all engineering schools in the world ...Good job
I love how it sounds like an old Biplane starting up... Just love it!
This video is also beautifully lit and filmed with great care.
Impeccable work.
I always wondered how radial airplane engines worked. Thank you for the very well presented video.
Thank you! I have always wanted to know how a radial engine works. Amazing!
This is absolutely gorgeous. I love to build things. The meticulous detail, and the cleanliness on this is outstanding. Very impressive.
Thank you :-)
I am actually impressed when i saw part 1 but I mostly enjoyed watching part 2
Good stuff. I went into a bar in Yuma, Arizona earlier this year. On the wall, they had a wooden sculpture. Customers asked what it was and no one that worked there knew. The barmaid asked me if I knew. I did. It was a wooden sculpture of a WWI airplane radial engine. A beautiful thing to behold. Never seen another one like it.
Outstanding! I appreciate the complexity, the precision and the imagination it takes to do this. I also appreciate the care and high quality videography it takes to present it. I do have a couple questions: Where do you get these ideas and do you do this for fun (hobby) or professionally (as in build working prototypes on contract)? PLEASE keep them coming!!
I've always wondered how radial engines worked. Now that I can see how. It's awesome. Really makes you appreciate the old aircraft that flew using them
Only, in (some of) the real aircraft, the cylinders (with prop attached to it) are rotating and the shaft is fixed to the fuselage.
Also, the firing order is not sequential in a radial engine. In this 9 cylinder engine, it would be 135792468. It would fire every other cylinder as you went around the engine.
I enjoyed every second of this video!! I've seen the model combustion engines in action as a child in the model planes my father build. Love this!
Glad you liked it!!
This happens when the timing of the magnets is faster than the rotor is spinning.
I don't often make comments on videos but I must compliment your engineering expertise, fantastic, thank you for sharing..
Thank you very much!
Lovely work, both the motor and the video editing. First class.
Wauw. Even the starting sounded like a full scale one.
Actually no, the full scale runs with petroleum so ya Mich like a combustion noise.
Yes It does, with that "hit and mis" sound at low revs. Would love to see this on a Remote Control plane(WW2) The Guys at Flitetest would get it flying
That is so cool.
At idle it has the same lopping sound that a real Gas Powered Radial Engine has.
This is 'Beyond' Bad ass. I'm speechless.
Thank you for sharing, beautiful machine!
Best thing from CZcams recommendations so far!
Beautifully machined.
I wouldn’t be able to resist the temptation to fit it to a model Corsair
what puzzles me - why are putting so many people their thumb down? I guess those are the ones who haven´t got a clue how this motor works nor how much skill it takes to construct and fabricate it. Congrats - excellent work!
Excellent craftsmanship. I learned today that all radial petrol engines have odd numbered cylinders
A true stunning work of machine art! Can’t imagine what those “thumb-downers” were. thinking...
Those are likes from Australia.
Fantastic editing and video quality
Thank you!!!
Well done, sound also cool! World needs more radial solenoid engine! 🙂 Keep them coming!
Nice Job kid! I always enjoy your builds
This is so beautiful! Instant sub!
That is an incredible beautiful peace of technology ❤️
Fantastic work man, looks great. I want to see it in a plane so badly.
This is amazing. Great job, also with the tiny 4-stroke engine
Thank you!
PS: awesome skills, really liked the Ali cover you did first but cool to see the guts at work, cheers.
An electric motor that sounds like a radial gas engine, how awesome is that!!!!!
++
Really a great job .WONDERFUL
This was really cool! Thank you.
A few hall-efect sensors, small magnet, some electronics to control the switching...
Very nice project!
Nah, contactors directly on the output shaft!
Correction: 8:04 Maximum RPM is shown as 1,808, but the detector is reading the blades hit, which it reads as 2 per each roatation as there are 2 blades for the propellor. So the actual RPM is 904.
May be the detector has a setting, where it auto corrects for this issue, if so let me know @Maker B. Thanks, I really enjoyed watching the video.
The detector works by reflection from the laser back into the optics. It is the same practice that we use to check an airplane's tachometer if it's reading true. No need to divide by two.
When it stops you can see that there's reflective tape on one blade but not the other. Hopefully the laser tach is only registering the reflective tape (ie one count per rev).
@@engineer_cat Yep, that's how they work. Otherwise too much or the IR light gets absorbed into whatever is being measured and it fails to return.
You got a great engine, I really liked it, I will put a like for your efforts
It's gorgeous! I love the sound of solenoid motors. I want one in an electric car or bike.
I'm disappointed the engine didn't drag the table across the room and fly out the window.
The Propeller was mounted in the wrong direction
Tolol
@@benediktfioriolli8165 Is that why it blew over his lego toys behind it, it was going backwards ?
@bill boyd oh... lol
Cause the holder is heavy ,thats the point
Best coffee cooler ever ☺️🙏
Just absolutely a thing of complete beauty.
Great job! I also need such souvenirs. Thanks for the video, I will try to assemble this model as well. )
ㅋㅋㅋㅋ커피 식히는 용도 였군요~ 너무 아름다운 엔진이네요 감탄하고 갑니다
Nice one. How do you drive it?
…?
Mate watch the original video?
Love your vids
Yes.
Drive
Congratulations. Wonderfull job!
This is great! Can’t believe there’s not a full scale one in operation out there in your garage to go on a real airplane! Pretty much a zero emissions one! Keep up the great works, wish I had the time to bring my creations to life too! The coffee cool 😎 at the end was a nice touch! Congrats!
* sees the domed acrylic front *
Yeaa ... That's gonna be a magnifying effect ... x)
yeaaa.... stfu
I wanna see him make a whole airplane at that scale with really scaled doen plain parts
That's a very nice rotary engined fan you built there, great work no seriously great work, this is how you take model airplanes to a whole new level.
50 years ago I made one of those as a project in 8th grade electricity class. Much cruder of course, and only one cylinder. (Modeled more like my store-bought steam engine that burned pellets under a boiler.) Wound the solenoid by hand. Crank shaft was a bent piece of clothes hanger. Flywheel was a steel coffee can lid. A cam on the shaft pushed copper strips together firing the solenoid from a big square 6 volt Ray-o-vac lantern battery. Nobody had ever seen anything like it. Maybe 600 rpm, way too fast to count. Wow, these videos brought that memory back, and the challenge of cobbling that thing together from garage scraps.

Age of Z Origins ad: *WARNING*
Actually I got a talabat ad lol
ONE THING MORE : YOU MUST TO ADD OIL INSIDE THE ENGINE to reduction the friction and sond 🥰👍
Bilal ELFAKROUCHI I think it sounds cool
@@jackjorgensen1440 Nah it sonds cool
@Salman Malik You're right about the sond
*reduce
Sorry I had to
@@rifkifirdaus2199 no
Fantastic work... A thing of beauty without doubt.. Good job. How can anyone put a dislike on this video is beyond me.... SMH
I just loved it!! Awesome👍👏😊
I think the term ridiculously awesome very proper for this toy, a term from one of the comments!
덕분에 기계공학과 엔진에 대해 관심이 많아졌습니다 ^ㅁ^
That is Amazing Bro. God Dame it. That Sounds quite Good
That’s the most beautiful electric motor I’ve seen.
Glad you liked it!
Its cool how the technology used in such a motor is also used to make speakers(coils) and other stuff.
mmm electric magnets, big wow.
Trying to sound smart lmao
before
Its the tech in speakers to make that engine not the other way around
A solenoid
That is by far the coolest desk fan I've ever seen. I might even copy it!
Gotta love the way the EM fields flex all the coil wires.
What did you drive it with? Please tell me you went old school with a 4017 and 555 and not an arduino!
This is the best ever. Great job. Well done...
Thank you!
That Sir, is extremely cool!
Looks like a dancing spider in slow motion 😂
But its pretty cool
Great! And "P.S." so funny ))
That's an amazing concept
I hope you are capturing that back emf man!!
Waiting to see pretty big RC airplane with this on it's front
@PunchingMegaTree well, I heard something about traveling electricity by wifi, dont know of its true but it should work on plane big enough
@PunchingMegaTree nope. This can, but not at high RPM. Needs a decent gear bc has a good moment like all electromotors do but struggles to maintain high rpm.
@PunchingMegaTree i suppose a really lightweight plane would work, a sopwith camel for instance
Maybe PeterSripol can help
not sure how efficient the motor is but if that weight together with the battery and radio plus the weight of the plane body , looks like 1800RPM isnt gonna make it.. that rpm is just barely enough to push the plane on the concrete but really isnt powerful enough for the take off run..
What sis you use for lubrication for the internals of the motor... you might have shown in your last video about making it but I don't remember...
Thanks, great videos...
Great build very impressed with the that mate , nice 🤙🤙🤙😊
Thanks 👍
THAT is soooo coool! I love the video!
Proposed changes to make it look even better.
1. Change the acrylic's cross section (AT the ends) from square to round, have the bolts be inside.That way you can still look inside and aesthetically looks better.
2. Under the brass cylinders, make a spacer (from whatever thin gauge material you have that's stout enough) that has two holes, enough for you to pass the wires through and neaten the whole aspect.
3. Hollow the stand and make a star shaped receiver for the wires. Pass them though and put the whole engine on a bigger base that allows you to house the electronic bits, switch, pot et cetera.
4. profit.
fantastic table fan 👍
Very nice work and craftsmanship
Excellent work!
For an electric engine (something i never thought i would say as an aircraft mechanic)This looks almost kind of practical!
You have a true mast-art rod & counterweight assembly on that crankshaft!
So frigging cool!
Would the induction on those rods heat them up too much to be usefull if this was more life- sized?
Well we have coolant for modern internal combustion engine and oil si why not use it for this as well
Plus they are being cooled by a lot of passing air
@@davidwelner9994 ambitious
@@davidwelner9994 there's no true need for the engine to be completely closed off too, you could have it exposed for more air cooling (though the drawback would be if something were to get lodged in it)
Incredible. At some point we could see a vibration mode due to the sampling rate of the camera being nearly exactly a inverse multiple of the frequency of that mode
Pure genius! Love it.
Now to see it in a flying RC plane. :)
Awesome motor.
와~ 저게 9기통 엔진이군요~ 대단하네요~ ㅎ

Honestly I admire you so much
Would like to hear more about the power source.
That feel when your coffee is too hot so you build a plane to cool it off
Thank you for this video. I enjoyed it so much I subscribed so I can find videos.
Glad you enjoyed it!
@@MakerB How about a 2 cycle chainsaw next??
On the last video I commented on adding a clear plate to the front to see inside. Thankyou sir
