Man I want a lathe

[@myfordboy]

As made the lathe has no clutch. There is a 3 step pulley on the spindle and a lever to reduce the tension for belt changing. I have made a bracket that deforms the belt when the lever is moved and so acts a clutch.

[@myfordboy]

Performance should be equal to or greater than the original as stainless steel has been used for the cylinder and displacer . This material does not transfer heat well which is desirable in this application.

[@myfordboy]

Sorry I didn't get the assembly videoed. It's pretty straight forward piston at one end displacer at the other. I'll put up details at myfordboy.blogspot.com in a few days time.

[@myfordboy]

It's an enamel paint from Pheonix Precision paints ( UK ) I usualy spray it but the weather here was poor at the time so it was brushed on.

[@myfordboy]

A displacer does not touch the sides of the cylinder so the the finish is not important. Its about 0.062" smaller than the bore.

[@myfordboy]

I don't keep a record of the hours spent. It took longer to film and edit the videos than the time spent in the workshop.

[@myfordboy]

I'll put up a description of the operation at myfordboy .blogspot.com in a few days time.

[@myfordboy]

Yes water! It will run fine without but if I were to run all day I would put water in.

[@myfordboy]

A mini project something authentic for it to drive.

Shmooth. If they ever do awards for online videos,like they do for the crap on TV,I'd vote for you. What's/ in the next series? A free energy machine/ If anyone could make one,you could ;) Sort out a donation button,and I'll send you a few quid.

[@antiussentiment]

What a stirling effort!! I always watch your videos wearing safety glasses so I can be safe imagining I'm there peering over your shoulder..

[@RaysGarage]

WOW, very nice work! I enjoy watching, and learning from many of your machining skills in your past videos, thank you!

[@not2fast4u2c]

i Have really enjoyed watching all the videos It looks Great !!! And the Video Qaulity has been excellent

[@myfordboy]

I have a couple of videos, "Lathe workshop for begineers part 1 and 2 " You might find these interesting.

[@myfordboy]

The red liquid is a neat cutting oil. It's an unbranded one I got at a show once.

[@myfordboy]

In the UK we quote the size as centre height, not swing. My lathe is 3 1/4" x 13"

[@BITTYBOY121]

Very nice work David - This hot air engine is another masterpiece on your part. Well done mate - I love it!

[@AdventureswithJane]

It's hard to add to what has already be said, however in any case, thanks. Since the first video in this series there is a least one more model machinist on the planet (me) and probably countless more. Thanks, from all of us.

[@renbooth4147]

I like the way that how nicely you made and put all the parts together from nothing to something that works. A job well done.

[@jaymoge]

that's really cool. nice workmanship too. check out what i found in the dirt last fall, similar concept but not nearly as cool as yours.

[@myfordboy]

Keep watching this channel for more projects.

[@MattTester]

Excellent work, I've enjoyed watching these videos too. Please don't make us wait too long for your next project.

[@Corneillecendree]

Très bel objet mais je n'ai pas compris le fonctionnement. Était-il nécessaire de nous montrer toutes les phases de la fabrication? À quoi sert la boîte à eau? Quel est le carburant? (c'est peut-être dit mais je ne comprends pas l'américain!) Au risque de vous paraître désagréable, tout ce que vous faîtes avec vos machines est très bien mais vous ne savez absolument pas vous servir des outils à main car votre façon de tenir une lime ou une scie est catastrophique et dangereux. Cordialement.

[@Trodan101]

Can you put an alternator on the engine and load it up, and measure the efficiency? I am sure BTU's can be measured by a simple flow meter to the engine, but what about the power coming from the flywheel? i have loved these engines from the moment I understood them, and to this day wonder when power stations will replace cooling towers with them, to recover ALL the heat from their fuel, or use molten salt from solar collectors, sprayed into a condensor, as the heat source for really big engines.

[@MrWFCJR]

Amazing range of operations. Mill worked as a drill press, drill press worked like a mill and tapping system, lathe worked as a mill and horizontal drill press. Creative use of moving tools to stationary pieces and visa versa. Would like to have seen final assembly. Also curious as to why not press or heat fit certain parts - used locktite instead. Water jacket simply filled up? Thanks

[@jgmagoo1]

I watched this whole series non[stop from #1 to #15 tonight and enjoyed it very much Thanks!! The only suggestion I have would be to show the assembley and fit of the displacer piston in it's bore. Does it not have to be as precise as the power piston? Does it actually make contact with the cylinder wall? The finish on it did not look good enough to accomplish this. Thans again for a great series!

[@hrxy1]

as an idea what about building a tesla turbine?

[@JohnRysdyk]

Well in the my machine shop there is a sign WWKD which stands for "What Would Kieth Do"(Turn Wright Machine). Now I will have to add WWMD, for "What Would Myfordboy Do". Keep up these great videos as there is so much I've learned.

[@Bobcat1963]

Excuse me... while I pick my jaw up off the floor.....WOW!" You have successfully done a brilliant work on your project as I watch every video as you were making it. I will be waiting for your next project myfordboy. two thumbs up & 5 stars

[@UberAlphaSirus]

WOOOOOO HOOOOOOO! It's done! Great work! I have learned a great deal from your videos. May I ask for a video in your 'way', how does this work. I would rather not wiki or google it, I was Hoping one day you would explain it. Thanks

[@sm870621345]

Incredible work! It turned out beautifully. What would this engine be used for? as it sits now, how does it compare to a real one as far as power goes? If you needed to, could you used this to power something?

[@fremebondo]

Are you going to post a video about the assembling of the parts? It is not so clear. Very good work, however. Looking forward for new creations from you!

[@FlexibleBladeTurbine]

Very well done. Working and filming! Have you ever thought of putting your outstanding skills to use into building more inventive engine designs?

[@mechanicmike2112]

ok i watched the whole thing from 1 to the final and it would be very useful to see a 3min. video on how you put all of the parts together, how they all work together and all...

[@stillbashingmetal]

Great, isn't it! Thanks very much for taking the time and effort to chronicle the build for us armchair engineers to watch from the comfort of our,errrm...armchairs.

[@mobythevillan]

Don't have to be a metalworker (I'm not, sad to say) to appreciate your efforts on this. Inspirational stuff....looking forward to your next project....

[@telosfd]

Piese of art!!!!!!!!!!!! I must say that the two negative votes are from Martians.

[@davidlong3824]

Fantastic skill love watching your projects .

[@bilkbarber]

David very well done. I have enjoyed watching the videos. Can you explain why you have to reach over your lathe to turn the spindle on.

[@jessefoulk]

Watched this from episode 1. Brought a smile seeing it run. Has a nice sound running. "Rrrum-Rrrum-Rrrum...."

[@mixed123456]

impressive! i enjoyed and learned a lot in this series. the quality and skill level is something to admire. clap clap ! to you sir!

[@aserta]

That looks very sexy. What a great build. I'm sad that it ended. Hopefully you're going to show us your next big project ??

[@45doubletapper]

Das ist sehr gut ! Well done job, you must already be thinking of enhancing and improving share your ideas

[@scheppach69]

A beautiful machine Myfordboy thanks for all the time and effort you have taken to show us how you made it.

[@billdlv]

Nice job the engine looks great. Your machining and fabrication skills are impressive.

[@danthefrst]

Just WOW! How a nice piece of machinery it came out as. How many hours dit it all take?

[@zyadbama]

Thank you so much! because of you I got A on my final project for machine shop class.

[@PerryRT]

Nice work! I'm curious, during operation, does the water jacket have anything in it?

[@impavitus]

I would hit the like button 15 times if I could. That is a work of art. Well done!

[@facundosantamariaelizondo4127]

Cordial saludo de Guadalajara Jalisco México Mi pregunta es por qué quitaste el video del motor Sterling? Sigues adelante Me gustan tus vídeos Muchísimas gracias por los mismos

[@myfordboy]

Which video are you referring to?. I have not removed any.

[@chungoongchang8367]

Good Business. I think in this time. If Anyone want to have plan, I would like to discuss for this item.. Because I am a Mechanical Engineer and Consultant for small and medium Enterprise.

[@zungruitelbitladnaternoche7305]

Amazing series, I enjoyed every minutes. Thanks a lot. I would have loved to see you assembling it all together in one video. Showing all the finished parts closely as you put it together then start it up and make adjustments for top performance. And as a bonus, show the strength of this beauty and see what it can power... Like a fan, a dynamo, etc... Thanks one more time, you're fabulous.

[@myfordboy]

Glad you like it. There is a video showing the engine at work here kzbin.info/www/bejne/mKanaJ-ehbOilcU

[@jsal0810]

excellent series, do you have plans to follow it up with another project?

[@antonyong6156]

How long do you think the project took to complete? in shop hours

[@strongtony9412]

What a great build. I enjoyed watching this being made so much.. but I don't understand how a hot air engine works.... I know what you gunna say..Look it up on the world wide web.

[@myfordboy]

I have my description of how it works at the bottom of this page myfordboy.blogspot.com/p/myfordboys-e-z-stirling-engine.html

[@spinesales]

WOW! Just beautiful. A true work of art.

[@cdickenson64]

Excellent series. Have you got any plans for the near future?

[@scoldedcat]

Beautiful workmanship. Congratulations. It's like watching war and peace. Once you start, you can't leave it alone.

[@baconsoda]

Now that is impressive. Super work.

[@robertanderson8613]

Awesome videos!! Thanks for sharing them. I would love to see a larger unit sometime, I would like to run one on producer gas and run a small generator..Again..thanks for all the grate videos

[@irrops]

Doodlum clank. I was expecting to see you having tea again.

[@thebrokenbone]

excellent and beautiful work ! thanks for sharing with us

[@koepketube]

Looks awesome. Can you put it under load? Power? What kind of belt was the wheel designed for?

[@myfordboy]

I have built a replica Essex turntable for it to power. You can see it performing under load here kzbin.info/www/bejne/mKanaJ-ehbOilcU

[@gj3072]

This is another great series showing a lot of tricks and tips for the hobby metal worker. Thank you for filming and uploading.

[@xgvargas]

Really beautiful. I hope you start a new project soon!

[@Ranglebox]

Watched this series of videos top to bottom. We'll be purchasing our first lathe in the next few weeks, I came to watch someone who clearly has lots of experience, to get to know what to expect. Loved every minute of it. Thanks for making such an elaborate video diary of this build! Also, what size lathe is this? Is it 7x18?

[@meradu2]

beautiful thanks for sharing

[@marcibb3167]

You are the man Great work. Thank you for posting

[@deler22]

Excellent work its great

[@springfielddews]

I envy your superb skills my friend. Thank you for the excellent videos. regards Michael G.

[@snipersquad100]

Excellent work, learnt a lot. Wish I had a lathe.

[@Ranglebox]

Yeah, I should get used to saying that (am English). It's nice to see you seem to be able to do most things on your lathe, size-wise. We're probably going to get something 3 1/4 x 14. Thanks again.

[@greenrolaids]

FREAKING AWESOME VIDEOS>>> SORRY I HAD TO YELL !

[@selawak]

good work, good video, can't wait next project

[@rikkiesix]

Stunning work man, great job. Loved all the videos that leaded to this beutifull finished product. Greetings from Belgium Erik

[@stormtaker63]

You are awesome! Fantastic motor! You did a great job showing us how you built this.

[@stevenk7015]

No wonder, your clock is a little fast! :P

[@clockguy2]

Nice work! I enjoy watching your channel.

[@igorantonov9725]

Excellent work!

[@JesemanuelRamirez]

Very cool, hope to see more soon

[@MilanDupal]

Great work!

[@musicmaneman38]

I'm still not sure how it works yet but I think it's really neat. My father was a machinist for 45 years. He used to turn 50' propeller shafts for ships and make 6' helical gears on a turret mill. Great work sir.

[@OndrejPistora]

there will be no completion video? :(

[@doors-vv3du]

[@rdmanone]

Absolutely brilliant work.

[@tuscanland]

Thanks for the great videos sir!

[@Journeyman-Fixit]

You are one machinist Guru my friend!

[@junglejammer1]

Great series! I do appreciate the time and effort that you put into your videos.I've learned a lot from watching them. Thank you, so very much. What is the cutting fluid that you use? It looks like automatic transmission fluid.

[@spilperson]

Thanks, you have given me a lot of enjoyment watching these. The engine is a beaut, and you did a great job in filming and editing, if there were youtube oscars you would be nominated!

[@Teunbaartman1]

Great, great video series!! Now I am really motivated to build one of my own. Any news on the castings yet. Can't wait. thx very much!

[@tonym1947]

A great piece of workmanship, enjoyed every minute. Unlike some sites on youtube you say nothing but show much. Looking forward to more .

[@Prowler901]

Excellent work! Been following along the whole series. Thanks for all the time and effort you've put in to share this with us. She is a beautiful little machine.

[@paulanderson2803]

If I close my eyes and just listen to the engine run it sounds like a 50 horse Fairbanks & Morse Deisel. Exelent series thankyou.
