I'm an electronics guy and know nothing about engines, this was still fascinating for me, I'd love to learn more about these engines and moving parts in general

"So just bear with me while I remove the bearings." Nice one.

This voice with this content just fits so perfectly

You actually might scare people away from buying on the auction site. That is a good thing because prices may then actually become closer to my very small budget!

"Bear with me while I remove the bearings" had me in floods of tears! Priceless!!

The care and love you show for (in this case) metal craftmanship I find inspiring, Keith.

I just love the contributions Keith has made for us steam nuts. His comment on this vid about reckless paint application indicating a bodged up job is all too true. I just bought a very early Stuart 10H on-line because it had the boxbed I needed for another very early 10H in my collection. The model had being painted by someone on LSD and sure enough, on disassembly, there was no steam slide valve. Oh well, I got my early (unavailable) boxbed.

What an excellent video of model engineering, it’s a great shame that this sort of engineering is no longer practiced. It starts in the class room early. When all the engineers have gone to the engine house in the sky it will be a great loss. Long live the real engineers. Gordon.

I love these old engines I built several of them back in 1966-73. They are very difficult to do and you must take your time and build them right no cutting corners. Otherwise you see what you get junk. I wish I could afford to buy a Stuart beam engine that was my favorite one. I used them as part of my engineering program for school. Blew the teachers away that I understood how they worked and that I made them and my own drafting work and report paper on the engines. Even the principal gave me a certificate at the end of the year for my hard work. I was crazy for Me. / Mfg. engineering. I wanted to build a Shay logger engine that ran on steam but couldn’t find the plans or funds to do it.

I don't know why I'm watching this or how I got here but... Nice Video

Nice video, Mr. Appleton. I´m 57. When I was 13 receive a gift from an old german friend of my family: an steam engine (one cylinder) basculating piston. Today is a ornament in my living room. Regards from Mendoza, Argentina.

Thank you for your time and effort in showing what "bad" looks like. It's easy to understand something that is good. Bad gets tricky.

Interesting and somewhat amusing video. I recently got into model steam engines, when I had to make one from scratch to get my machinist papers, and I did some research on youtube which is probably why this video was on my recommendations.

Thanks for taking the time and trouble to prepare this video. I appreciate your showing "how not to do it" and what to avoid.

very soothing to watch and listen to, as well as very interesting. Marine and Mechanical Engineer here, and just eat this stuff up!

Very enlightening as well as entertaining. Twelve minutes well spent. Thank you.

Ive just stumbled upon your channel, and I love it! This is great! YOU ARE CORRECT with the different color parts, as its usually means someone else has been tinkering with it before ;)

Great detail Keith, precision is everything !

I risked machining my D10 crank from solid as a test of myself, and it was very hard but very satisfying. Pages and pages of conversions from fractional imperial to decimal imperial, and shedloads of panicking. Luckily I got it all within spec first time, but a bit of a scratchy finish on the centre bearing surface, so not perfect. I plan to take it a few thou undersize to get the surface finish ok. Overall I am very pleased. Until you have one of these cranks in your hand it is hard to visualise how delicate they are when un supported by bearings! I think a loud sparrow fart in the garden would bend it. I am now constructing a drill rod/ silver steel jig to perfectly align/ position the crank bearings with the cross heads, and then do something with taper pins to make the position repeatable. Every part of my milling machine is positioned with taper pins, then bolted...they used to do it properly in the olden days.

A fun and excellent video. The more you've worked on these things the more you can appreciate your work and comments. You are a funny guy, and this was great!

Now there a machinist that has seen it all , Thanks for your demonstration about what NOT to do if your a backyard mechanic trying to turn scrap into anything much better than scrap. For a novice to try to make this work even 10 percent better than it was is nothing but wasted time, aggravation and money down the drain at the end of the job.

It is great that you take the time to enlighten us all to the potential pitfalls when making a purchase. Well done to you Keith.

This showed up in my feed for some strange reason. I watched the whole thing. Glad that the gaskets were good.

Found by accident, very nice explanations, demonstrating and warnings. I would watch you more if I have a hobby of rebuilding these great little engines. Many thanks!

Thanks. The close ups of the crankshaft repairs were very useful. Beautiful bit of filming.

Nice video and I enjoyed listening to you speak.

I'm really getting nostalgic right now! Use to work at Sulzer in Switzerland and we built Ship Diesel Engines years ago, just a bit bigger. However, I always loved model engines as well!

Awesomely Useful, thanks for going to so much trouble to educate us, I found your style, knowledge and approach to be fantastic.. Well done, thank you..!!

years ago when I was in my 20's, an old foreman I was working for told me one day " there's never enough time to do a job right the first time, but there's always enough time to do it over". nice vid

In the basement of my school there is a similar steam engine but larger, it powered lathe before electricity. I have picture of it and I will send it to you if you want . Lathe is from 1756 .

This was really informative. I've never worked on a steam engine repair and due to this video, I probably never will bother to do so. I'll just buy a good one in the 1st place. Thanks!

In 1950's I got a steam engine for Xmas... about a foot high... electrically heated water/steam tank, cylinder swinging back and forth against a base with holes did the valving for the steam... very simple... I used it to power a vehicle made with an Erector Set...

Excellent video and very informative, Its good to watch a craftsman at work. I have an old Mamood steam engine which came with a very old Mecano set which was given to me many years ago. You have renewed my interest in getting it all to work!

I am never going to engage in a project like this... But what a wonderful presentation and demonstration of " Good Hands"... Thank you... Very much enjoyed.

Yes, I found this video very helpful, I never realized that there were so many ways to mess-up a crankshaft. I do not understand why they threaded the crank parts and the webs to fit them together. thank you very much for this display and lesson.

forewarned is forearmed thank you - considering the absurd prices for steam motors (every time I look for steam engines I get model trains, ELECTRIC model trains!!! Grrrr!) you are helping keep the market honest. The way these things are priced, I suspect they are being sold by gasoline company executives! Very discouraging to see the condition of that used engine, it's like peeling the label off of a 'rolex' and it has Timex underneath...

As a retired stationary engineer. where in our plant we had real steam engines. I must say, I enjoyed it very much. I did know they made ones like this. Think I will look into getting one.

Nice narration and very interesting! Thank you for making this! Best, Rob

Just happened across this video. Good'ol algorithms eh? Great to watch, it was obviously a two bearing crank after seeing you spin it in your lathe. You'll not run that in with a drill!! Very pleasant to watch and listen your comments. Loved the line about the gaskets. I have subscribed. Thanks a lot

Nice video Keith, but I did think you were going to say, "once it is in the box we throw it out the window".

I could listen to this guys voice ramble on about most anything. Quite relaxing. lol!

I have always loved steam engines. And have been contemplating using one as an off grid engine for a generator.

Excellent video. I was considering buying an already assembled steam engine on eBay awhile ago, and I’m glad I didn’t at this point. I guess it’s important to have a video of it running correctly if one is going to spend the hundreds of dollars it costs to buy one of these pre-made. I’ll be looking into those PM research pre-machined kits.

thanks for experienced advice, instructive content and charming delivery

Just a suggestion. Instead of tapered pins, I know demo only. Just disassemble the crankshaft. Clean all parts with brake cleaner. Now place a drop of RED loctite on all the threads. Reassemble crank. Now, place a live center in the center drilled hole you made. Use a dial indicator to be sure the shaft is straight on all the segments of crank. Be sure to maintain the 90* angles. Once all is straight on the dial indicators. Just use a small flame on a torch, or good lighter. Warm all the joints where loctite was applied, not to hot to touch, just warm. This sets up the loctite very quickly. Now let set for the night. Crank is now effectively a one piece crank.If you ever need to disassemble it, you warm up the loctite till it starts to give off smoke, then loosen joint. Use a mask, as the smoke is hazardous.RED loctite is permanent on shafts this small of diameter. Not historically correct, but only you will know. Just my two cents.

Learned a lot about that poorly made steam engine. Thanks

Quite an interesting and concise video. You did an excellent job of discussing this sloppily built engine. It seems that every component was either suffering from a lack of quality in build or design with a touch of manhandling to spice things up. You as I agree in being suspicious of mechanical objects that have non-uniform fasteners and paint in places where it doesn't seem necessary. I really don't understand why someone would invest their time and money designing and building something so poorly. It's a nightmare from the start. I would hate to see the aftermath of what an excessive amount of pressure or RPM would do if someone happened to be near this particular contraption if it flew apart. You did the right thing by gathering it up and placing it it the drawer. At least it was worth the instruction that you gave on machining.

Interesting observation that poorly designed engines typically have their little "fiddly bits" painted a different color. I propose the reason for this is because the builder/designer/engineer of said engine was more concerned with how the thing _looked_ rather than how it _performed._ There is certainly nothing wrong with aesthetics, but that concern should should FOLLOW ensuring that the design is mechanically ideal. A solidly engineered device sells itself, even if it's ugly. However, flashy sequins, rhinestones and glitter are needed to make the "turds" more appealing.

Honest Cheeky English Machinist demonstration, opinion, and humor. :)

Thank You! This is a wonderful video. I thought there was hope for the engine until the end where you told us that the gaskets were the only parts of the engine you would keep! Hillarious! Some people do not learn from the good advice of others. Perhaps they will do things the right way to just spite the examples in this video.

Excellent info , thx Saved some people grateful for it .

Taking your point on gratuitous painting of ancilliary parts Mr Appleton. . It's the equivalent of seeing a second-hand car with the tyres covered in 'tyre black' and the engine bay freshly steam cleaned. You just know that chances are.....it's a dog.

Hi... I do not have a model steam engine... never owned one and don't think I ever will, but I was transfixed by your video. It's probably your speaking voice and accent, very honest and straightforward and the video was filmed and edited really well I do hope you have the opportunity to pass your skills on to a new generation. We need more engineers in this country and had I had a teacher with your delivery I would have been really engaged with the subject This is the kind of YT video I absolutely love. Well made, informative and generally interesting... I liked it so much I've just sent you some paypal pennies Thank you

Some of the issues you pointed out were obvious to a machinist. Others not as much. Thanks for this very informative video. You did a wonderful job of illustrating exactly what was wrong and why you shouldn't bother trying to "repair" such messes. Excellent. What an awful job of constructing that engine by whoever had it before you. I might have to subscribe to your channel just to see excellent machinist videos.

I like you hit the crankshaft with a soft "thumbfinder" off-camera.

Very enlightening; thank you for sharing.

My father passed away a few years ago and I have found around 20 of those engines some are built some are just castings thanks I'll know what to keep a eye out for now.

I ignored this so called recommended video for weeks, now i finally clicked and i am very amused.

This was fascinating.

You’re so great, Keith. Love your videos.

I love KZfaq at times. Started with a video on Theater organs, pass through videos on Atheism, and end up here, simply marvelous!

Such nice presentation. Pleasure to watch.

I loved this video I have always been interested in steam engines, I made a oscillating steam engine from scratch as my year 12 metalwork project

that engine is salvageable with a new one piece crank shaft turned between centres to ensure it is true , the two throws should be turned after the main bearing areas using a jig to give them 90' offset to each other , the existing main bearings are salvageable , bolt them down to the bed then use a hand reamer to ream them out as needed so they are perfectly in line with each other , turn the crank main bearing diameter to suit your new main bearing ID , job done , great video take it easy

since I don't work with small steam engines I won't find the video useful but I did find it to be quite interesting and very well-presented

I love your overuse of descriptive adjectives! Very Colorful, indeed! :)

This is very clever, Keith. Thanks.

I've got no particular interest in steam engines, but I enjoyed your video and will probably watch some of your others. Thanks Keith.

I see your point about Vanity. Ive had many projects where I was under the influence of a person who is preoccupied with ascetics, and not form and functionality.

Hi, nice video and I agree with all of your comments and complaints. I actually live within 1 mile of Stuart Models and upon request, have recently drawn in CAD one of their Twin Cylinder Steam Engines. The company have invested heavily to produce parts for each of the steam engines on their books. I think the painting and poor fits/workmanship is down to the engineer building the engine not Stuart Models, even though they supply the parts as a kit. Again, excellent video, and I like the relaxed way you go about explaining the problems , and the joviality introduced to the commentary. Thanks

That was fun, even though I have nothing to do with these steam engines. I fiddle with 2 stroke Rotax engines for my little ski-doo's.

your a really good machinist i worked in a shop when i was younger . but i liked working on cars so i did that instead thanks for the tips .

After your string of disclaimers thru-out, somehow we all knew the Little Engine "that couldn't" would go back in the drawer. A good lesson for those contemplating a dead end project... Thanks!

Thanks for this video, I didn't know anything about these.

I'm not really even an engine hobbyist. I'm more an artist and a writer. But your videos are strangely addictive, and you make model engines seem very simple.

Thank you for the lesson.

Good tip on the paint observation perhaps those come out of a factory with much less. Quality control , pride, or engineering or a combination of all the above ? I dont have much experience with the newer models but my wife’s Grandfather ha many older model engines that were made very well And because he was a retired Steam engineer they ran well. Although i suspect that he made that happen by machining and balancing things himself many of those engines were installed in wooden toys he handcrafted as well

Great review of the engine and it's issues!

great vid! we're all bumbling around, and you're validating our incompetence, and giving useful knowledge as well. thank you...

When I built a Stuart steam engine in the mid to late 60's while at school the piston and crankshaft were supplied as cast iron. As I remeber it I machined the crank shaft in a four jaw chuck on the schools ML7 lathe, also there was no piston rings but the bore and piston were a good sliding fit.

What I got from this video. “Don’t do this. “

Loved this-----thank you

Parts are a different color = Someone else has been into it already ...

I like sloppy, chipped, leaky, greasy, "kept working" ghetto rigged machines. That one stud is the cutest thing ever.

Excellent narration.

Well...looks like that engine ended up in it's PROPER location! Good video, Thanks!

G'day Keith just one question how would you go about making studs, do you use a collet in the lathe? or just turn them in the chuck. That's a lovely old lathe regards John

thanks for the info, though ive just bought a new engine in kit form, everything is new include boiler, so i know its been put together well. i did have my doubts buying from online auctions.

I could watch your videos all day.

That was fun to watch. Thank you

Very good info , Thanks

I see in a new light my Stuart Number One, bought as sand castings when I was 18 which took me 4 years to build to clearly a relatively high standard seeing many of these engineering horrors. Much learning and a few mistakes along the way, nearly 40 years on maybe time now to look at an upgrade to reversing motion.

Great engineering ! Most enjoyable.

That was fascinating - thanks.

Came by this by accident and glad thai i did.Very well presented.It reminded me of the Out of Town series i watched ,as a kid,with Jack Hargreaves.👌

I have machined several cranks from solid and well you may say your not a machinist but well neither am I ! It's a good exercise to have a crack at !

Grand video , information and warnings . Interesting 👍🇬🇧

Best video I've seen in ages!!!

Don’t know how I got here but very educational. I learned something.

Thanks a Million for such an amazing upload 🥰🙏
