Man vs. Manson Engine

[@vandalsgarage]

Your channel is criminally under-viewed. Keep doing exactly what you're doing, its inspirational seeing what can be done with recycled material and home shop grade machine tools.

[@Watchyn_Yarwood]

Why I subscribed: I was referred here from somewhere else. The first video I chose to watch, you made the comment "This channel is called Jeremy Makes Things no Jeremy Buys Things From McMaster"! That all it took! Love your ingenuity and skill!

[@TonyUrryMakes]

Enough information - no boring crap and no stupid computer noise some call music. The aesthetic of this channel has yet to disappoint.

[@MachiningandMicrowaves]

"Pushed it to the Back Burner" excellent! I actually laughed out loud. My Chihuahuas were very alarmed

[@jobkneppers]

One tip: aluminium sucks as a bearing material. Always. No matter what the mating material is. Thank you for all of your nice content. Especially self taught! Best! Job

Gladly ‘playing along’ - great video, no waffling, no music, learning experiences shared, quite a journey, but with a happy end! Nice framing too, so all round a really pleasant way to bridge the time between dinner and bed :)

[@ferrumignis]

I'm impressed with your persistence on this. This is the first time I'd heard of a Manson engine, going to do a bit of research as the simplicity is attractive. I built a small Stirling engine on my clapped out old lathe, seems like they are quite a lot easier to get running, though at the expense of more complexity. Might it be worth adding some insulation on top of the base to prevent radiant heat reaching the cold section?

[@camillosteuss]

Very good idea, like a turbo blanket on a car... Keeps the hot side hot and prevents the cold side from getting hot by radiance... Just might be a good thing to try and apply, should rise the efficacy a bit, but talking about a few % on numbers small enough where doubling does little in terms of applied work is a bit silly, but bravo, more than admirable in engineering way of thinking and not adhering to stupid rational approach where you would consider how soon the blanket would pay off...

I love the determination! I know there was a lot of frustration off camera but I'm glad you kept moving! It's def proof of concept entirely from your own design! I love it!

[@CraigsWorkshop]

Wow, that was very cool. Challenges overcome! And the video too - great shots, humour, and storyline. I also loved seeing you chuck up the rusty ratchet - true to the repurposing style. :) Cheers, Craig

[@jozefa1234]

Hoi Jeremy, I build a few different strirlings myself but never heard of this system. always trying to make all parts leakproof , but never drill a hole in the cilinder!, quite different to solve every friction point to run smooth. but great to see it run at the end.

[@RamblerMan68]

Love the persistence! Like so many projects I've undertaken with the lathe and mill....me and my actual machinist friend laugh at what we would have to charge for the same thing if someone wanted to buy it😂😂...so of course, nothing ever gets sold🙄...but a lot of learning occurs...thanks for sharing!!

[@danielabbey7726]

Super interesting project! Not only did you show us all the steps/mis-steps in the build, but you also gave us your thought process on the changes needed to make it work. Not to mention the great videography.

I have been on the platform for many long years, and this is my first comment. You make awesome stuff Jeremy! Some thoughts: Can you get C3 bearings maybe? More slop, but they run very smooth, especially when you get out the grease and run them on thin machine oil. And I think someone mentioned the large mass of the propeller being an potential issue. One day when I have more machinery I shall attempt building something like this too, best of luck!

[@Trouble-oq4ze]

Very nice intuition, great execution, very cool conversation piece.

[@Mad-Duk_Machine_Werkes]

"Hollow Mill" - AWESOME! I got a whole box of those and had no idea what they were for? hahahaha

[@anomamos9095]

Tip Try putting a hood over the base to shield the cooling fins from rising heat, but have a duct to vent the heat into the stream of the fan. Shape it so that it catches the rising hot air to duct forwards.

[@ChirpysTinkerings]

Looks good man. It might still have just a little bit of friction in it, Ive seen people using powdered graphite lubricant in the stirling engines to help.

[@JeremyMakesThings]

“Thank you for your feedback, I’ll take it into consideration.” (Inside joke, lol) But seriously, that’s a good thought. I’ll have to see if I have some. I’ve been using light (sewing machine) oil for it, but graphite is worth a shot.

[@ronwilken5219]

@@JeremyMakesThings There is a light machine oil that has Teflon in suspension. Comes in a hypodermic style tube. Used to be able to get it at Radio Shack which, unfortunately, no longer exists in Canada. It seems to work better than sewing machine oil.

Very cool project!! Maybe try either lubing with graphite or making some of the contact parts with solid graphite it makes nice low friction bearings at low speeds. I just have to say as a machinist, you are doing a great job with your “clapped out” machines! Nice techniques and great assortment of tools! Keep up the great work I’m definitely subscribing!!!!!!

[@troycooper3513]

Best video ever... you show things and explain things so perfect... thank you...

[@MrKingdavis13]

I am no expert or anything but I think I would try to make a much larger bore with a much shorter stroke to make better use of the thermal energy. I would try going to like a 5 inch bore with a 2 inch stroke or something and you could try making an actual crankshaft to mount the fan and spread the load with a bearing on either side of the connecting rod. I would love to try building one myself but I don't have the tools.

[@autochton]

This project really makes clear that simple does not mean easy.

[@bernarditaylor7593]

In my opinion all of them are easy!!! Problem is what type of Machinist are you? That's probably going to be what type of machine you going to produce!!! When I attempt the new design I do all my testing without ball bearing!!! Why I can easily find drags. Can't have life without troubleshooting!!! I tell you that's the only time like the think and work is when I'm working in my machine shop. You guys have a great day!!!

[@donmittlestaedt1117]

I've never made such a device, but I share your affliction brother.

[@russcooper9628]

Congrats on getting that thing to run! One thing about these hot air engines is that they don't scale very well. That's probably why many of the models you see are quite small. If you have a running engine and simply double the size, the volume of air that needs to be heated increases by a factor of eight, but the area available for transfering that heat only goes up by a factor of four. Physics is physics, and I'm not sure if there's any way around that problem. I understand the appeal of the Manson engine. Only three moving parts! But if your real goal is to make a stovetop fan (and not a Manson engine), you might consider the Moriya Stirling engine, which does work as a stovetop fan. Good luck!

[@OliWard]

Absolutely brilliant. Great project, great explanation. Hard subscribe.

[@Bakafish]

You know PTFE outgasses deadly fumes when overheated right? Seriously deadly.

[@scottmasson3336]

Wood burners cause cancer.

[@deandaring529]

The difference in temperature between the "hot" and "cool" chambers was probably far too small to counteract the friction created by your previous design. So yes the friction was a problem, but I think a better design of the chamber itself combined with a reduction in friction would result in increased efficiency. Because essentially you are pulling in "cool" air from a port that is only a few inches above the source of the hot air. I would suggest maybe using some insulated tubing that extends to the floor where the air is far cooler to increase the difference between the "cool" and "hot" chambers of the engine, this would greatly increase the energy generated by the engine and may counteract the friction it was experiencing in the first place without a complete redesign. Admittedly this is my first time hearing of a manson engine and quite frankly I have no idea how they really work, so this is my off the cuff interpretation of the problem.

[@darellsunderlin4670]

I built one with heat transfers and a $ 2 pellatier , works great .

[@haydenc2742]

Any new updates on this? Definitely want to see a working version!

[@christopherblack6607]

Excellent work!!

[@plepgeat]

Very cool. Maybe a much wider and minimally more massive aluminum base with a thermal coating on the top to trap heat and allow it to go only into the engine?

[@andrewslater6846]

Dang it! Why did I have to find your channel during finals week?! I need to study but this is what I find interesting. Oddly enough, watching these machining channels is much better than my manufacturing methods class. (im studying mech E)

[@doczoff5655]

I'm going to post my thought process on improving this design entirely as an example of my own astounding dumbness... If the base was inside the woodburner it would receive far more heat... but so much it would probably warp. So add a coolant, say maybe water?... ah no water boils at 100C. Hang on though, the expansion when the water turns to steam would give a really powerful stroke... I'm a genius!! (pause while mental cogs fail to turn.... wait for it... ah there they go...) D'ohh!! I'm so not a genius!! Congratulations on such a fantastic level of engineering inovation and accuracy using such limited resources!!

[@JeremyMakesThings]

I think you may be on to something there, Doc, but that gets me thinking that it would be even more efficient If you could somehow get the combustion inside the engine. Like a little, carefully timed, controlled explosion. That would seem much more efficient.

[@doczoff5655]

@@JeremyMakesThings We're both missing the obvious here, if you introduce enough fissionable material you can stay warm without even needing to light the woodburner (might save on lighting to).

Based on several uses in this video, you obviously do have some wonderful machinist jacks. Just like I imagined. 😉

I think steel wool would make a good displacer, since it would fulfill a role as regenerator as well.

[@metusa666]

Just a thought is the cooling fins doing their job good enough try blowing compressed air across them with the fan blades removed. just an observation not a critism I enjoyed your video very much thanks

Great job so far! How much can you hog out of the back of the fan blade hub to compensate for added blade weight? Just a thought

Very interesting! Just found your channel and I love what I’m seeing. Your way more persistent with use of scrap than I am haha. Keep up the videos they are very interesting

[@chrislee7817]

Would a bigger diameter piston help with the heat transfer? I have a toy sterling engine and it uses a very large thin insulated piston.

[@JeremyMakesThings]

The ratios for the Manson engine between the displacer and piston are pretty well established. It seems that the advantage of the Sterling design is that you can run a much larger displacer compared to the piston, so you’re heating and cooling more air to drive a smaller piston.

[@insideout144]

It takes balls to put up a machining video good job sir you now have another "fan"

[@stevebray71]

Live the way you worked through the process just a thought 💭 what if you was to change the size of the hub that the blades span on to make it smaller it would maybe have a difference in the rotation speed if it was lighter as said just a thought 💭

[@crichtonbruce4329]

More great stuff. I'm learning a lot from you! When you have the unit on the stove without the blades does it spin faster? Is there a design problem that the whole thing is on a stove heating the cold side preventing it from being effective?

[@JeremyMakesThings]

The blades don’t seem to make a difference, I think heating of the cold side is the bigger (biggest?) issue.

[@ronwilken5219]

@@JeremyMakesThings just a thought but what if you made a "horizontal" engine with the cold side over the side of the stove instead of a "vertical" one. Food for thought. For a science show at high school we produced a sterling cycle engine heated with a Bunsen burner. It would work horizontally but not vertically.

[@mrjibrhanjamalkhan2144]

Where the blades attached is a huge lump maybe something smaller and lighter would allow it to move easily

[@jeffersonluizbento20]

[@stevendephillips2490]

Good job . This made a subscriber out of me.

[@ubergeek72]

If the fan was pitched the other way, wouldn't it keep the cold end colder?

[@JeremyMakesThings]

The engine will run in either direction, so it can either push or pull. I presume pulling would keep it cooler.

[@Mister_G]

Brilliant! You made it work! - A really entertaining and fun video, too, thanks :)

[@jonbaker3728]

I think some 3d printed, VERY lightweight fan blades may solve some of your problems. That is a lot of weight out there for that little engine.

[@RodRosenberg]

Very cool "IT WORKS IT WORKS"

[@peterjohn63]

Even if it's not effective it's a tribute to your technical prowess amateur or not ,,and a fine ornament ,

[@jbodden6977]

THE LOWER THE MASS OF THE DISPLACER THE BETTER! DITTO FOR THE CONNECTING RODS... magnesium allow would be probably the best...

[@Skwisgar2322]

A better and safer solution for limiting heat transfer between the displacer and shaft would be to use stainless steel (very low heat transfer coefficient for a metal) with a thin crossection. This is what 3d printers do.

[@bernarditaylor7593]

Have you had any more good luck with your manson engine? You got me interested in wanting to build one now. Gor i can truly understand the different between the two open and close system. The first thing I would do in your case is take that fan blade off and tested it with a flywheel! Your problem maybe weights and balance. I understand that behavior of a closed system it would be a learning process to understand the behaviorally open system! Always like to feel some type of compression when applying heat but that's a closed system. I've had multiple problems with hydrogens and most the time that boils down to the power piston. Didn't make it properly it wear down all sorter of things that was Overlook in the power piston.
