You are correct about the ratio of mass and weight to the size of the drill bit. Considering the size of that assembly and weight of the angle plate your did just fine. I would not have done it much differently. Problem is far too many of the people criticizing you are armchair quarterbacks. I took my training as a tool and die maker in 1972 and if it means anything to you, I like the way you work. I am retired now and I have discovered you tube. I like your videos. I am going to order that large steam engine you have recently started. Have fun and stay safe.
I have a full size steam engine 8 inch bore and a 10 inch stoke, similar to your model, I run it with a 40 HP Case steam boiler, it is lubricated with one of the steam condensing water lubricates you are talking about, they use a special steam oil also the cylinder is lubricated with graphite. I enjoy your RUclips episodes, you are a good teacher.
Hi Quinn - i am a retired toolmaker, but not hesitant to check out youtube when starting new projects. again impressed with your steam chest presentation. Just finished my 4th engine build. All from ideas on line, but my own designs. Just had to make this one with a steam chest. Did get some very valuable pointers from you. Much appreciated, Howard
Also, running your engine on compressed air is very different from running it on live steam. If you make your engine too precise, heat will make parts expand and the engine will stop, it is really a very fine line between having it run smoothly and not running at all. I built a few engines, I have no idea why I keep going back to making small intricate parts for tiny machines, it is time consuming, frustrating at times, but it is highly satisfying to see them run at the end.
Lovely project. Your explanations are almost always clear, complete, useful, and entertaining. Your channel is one of my 3 or 4 favorites for the hobbyist machinist. I agree with so many others here: the internet _loves_ you.
That little bit of "Chuffing" at the end of the video was just fantastic. When we build steam engines that's the sound we are waiting to hear, soon it will be Chuffing of steam.
Your skills are incredible. I'm gonna build a very small-scale steam engine for the first time and hear that they can be built imperfectly but still work gave me hope. Thanks.
You must be an Engineer. Love the detail in your work and description of how you attack problems. Ignore the complainers, and yes, the internet loves you!
Fantastic job! You are solving one tricky problem after another! I learn so much from your videos. When the engine is done I hope you make a beautiful recreation of a real world installation using model railroad techniques to simulate a masonry base with brass handrails, a dynamo, light and other accessories along with the boiler. . That would be a real masterpiece and heirloom item to cherish.
Well done on your progress . Nothing wrong with transferring holes , it has been done that way for years .After all we are building steam engines not space rockets . I am also pleased to see you know which port the steam comes in and goes out . As for your first comment in vid about “ making the internet mad t you “. Do not worry . Like me you are a hobbyists and we make do with what we have .i assume you do it because you enjoy it and not to belittle others .
"...After all we are building steam engines not space rockets..." Have you seen what goes down in Boca Chica? I supect they just stick a sharpie though the hole and then drill roughly in the middle of the mark! :-)
You got me almost ready to order a kit for a winter project down here in northern MN. You are doing a great job and at a level us hobbiests can work at ! Thanks Mark
I've been fascinated by the complexity of steam locomotives since I saw one in 1957 when I was 3 years old. My parents took a train powered by that steam locomotive from New York City where I was born in Upper Manhattan on May 3rd, 1954, to Cleveland Ohio where my dad's parents lived. I'm also happy to see many old steam locomotives restored and brought back to life. The best one yet is the Union Pacific 'Big Boy' #4014 one of the largest steam locomotives ever built
Hi Quinn, I just read you comment policy linked in the description and it was the most delightful thing I've seen all day. Wonderfully written and so spot on. Well done. Thanks for your vids, your example, and your awesome, self-deprecating style. I'm an even bigger fan now. :)
Love your work and particularly that you you let us know when your human infallibility strikes. It makes us feel not so stupid. But I did notice that when you mounted the cylinder with the transfer screws to mark the hole positions, you had the valve chest hanging out the opposite side to that which you chose to finally fit, that’s why you had to loosen up the clearance holes. (7:26) ( right hand side looking from cylinder down to crank and you are mounting left side looking down to crank. ) I spend a lot of time marking up castings with dyfken blue to indicate features, orientations, alignments, pairings etc as well as for marking out. More importantly for anyone running a steam engine on compressed air, you can buy inline air supply lubricators for old style air tools that needed oil mixed in with the air supply. Just search air tool oiler. They are cheap and replace the displacement lubricator when using compressed air and not steam. A MUST HAVE. Steve
We could never be mad at you...she did what?!?...OH MY GOD! IMPERIAL, METRIC, and yes, WHITWORTH FIST SHAKE!! Oh, it worked beautifully? Well of course it did. Nicely done! We knew you could do it! That was pretty cool. The whole steam engine is amazing to hamfisted me. Thanks, and Meow to Sprocket.
I'm working on this engine also in my spare time, I was a little worried that you might have issues because you steam ports in the chest appeared to long but I need not have worried it works great! Keep up the good work I'm really enjoying it! Now I have to get out to the shop and catch up with you!
I'm starting to look forward to your posts as much as Leo and the rebuilding of the *Tally Ho!* It's interesting to see the difference between a plant steam engine and locomotive steam engine (thanks for the referral to *Mr. Crispen* - he's a treasure!).
Make a drill guide for your holes. A round blank or square then drill your pattern thru it with all the holes, the big bolt pattern and the small holes, and leave a boss in the center to locate on the casting unless you have the right size pin to locate the center hole. I never use punch marks for close tolerance holes. maybe for an oil pan. Just a different way of doing it. Try a 3 fluted end mill for slots. All I use now is 3 flutes or 5 flutes or 1 flute. Keep it odd Blondi.
Let's say civilisation collapses (and you still have power, by whatever means), steam engines look possible to construct in a home shop, but are combustion engines possible for a hobbyist? I'm thinking like "with some learning I could recover society to steam level" but no further.
This is wonderful, very helpful and interesting. I'm thinking of making a narrow gauge Steam locomotive and build a small narrow gauge railroad around my house. Thank you for existing!!!
Have you ever used a Noxon punch? It's a short prick punch butted up against a short center punch with a tension spring between them. You pull on the one end and the spring drives the other end into the work. They have great feel for lighter marks and enough wallop for deeper ones.
Funny story, I bought I lot of tools from a retiring machinist and found a bunch of those "transfer" screws in his box in a wide variety of diameters and thread pitches. Coming from a fixture design and build background I thought they were just a niffy way to keep around set screws for when you needed. But, now thanks to Quinn I know what they are actually meant for (and the more I think of it, the more it makes sense why they are used in that manner.)
I like the fact that you used a drill press to drill some decent holes in your project, not everyone has access to fancy tooling or high-end machines and most of us are hobbyist still trying to figure things out. GREAT JOB, you are AWESOME in my book.
Hopefully, whenever the "professionals" that tell you what you are doing wrong, you'll know that there are a crapload more people like me, who learn more from your videos than any of the "professionals" have ever taught me! Please keep up the great vids!
As a professional i can tell you it only get's worse there is allways someone knowing something better but aktually just telling shit or he tells something thats outdated like 20 years before but he learned it that way so it has to be that way ... There is allways something you can learn and i guess a hugh pro to "hobbyish" People is that they aktually have to do it by themselfs no matter what
Noice! Some might pooh-pooh the idea of transferring hole positions, but if it works, it works. It's a preferred method of Kozo Hiraoka, so it's certainly good enough for us mortals. I appreciate your Extremely Concise History of Steam Engineering, very interesting.
Then some people have never dome more then play in the basement. Millwrights who do it for money do it every day as do tool makers. - Just what do the cork sniffers think all the transfer punches and screws ae used for?
Thanks for the excellent description of how it all works. I've always been fascinated by RR steam power. Union Pacific has a big presence in Nebraska with a Challenger on static display in Omaha and the Big Boy moving through the area when they have it out for fun. The atmospheric engine they have on display in the British museum is interesting. Talk about a big cylinder! Simple engine.
Excellent video, Quinn. I have long been want to build a steam locomotive, and I've found your videos on machining very informative and applicable. Thank you!
Hi Quinn, Great video, I always look forward to your installments and have been following along on the steam engine build since the start of it. You do excellent work, your machining skills are a credit to you, again well done. I felt a need to comment on your channel about your comments on the transition of steam locomotives to Diesel Electric Locomotives, as I felt they were not quite correct. It is true, the 1940's modern steam locomotive was at its pinnacle of its development, and those large articulated steam locomotives packed some serious horsepower, 5000 HP+. As developed as they were, they were never more efficient than a Diesel Electric Locomotive. A modern steam locomotive required large amounts of maintenance, but their largest downfall was their inability to operate over large distances. If a train was to operate from Chicago to Los Angles (A distance of 2200 miles) it required the steam locomotive to be exchanged nearly every 250 miles as at that point it was nearly out of coal and water, fresh engines were installed and the train continued. In 1934 when the Santa Fe introduced their new train the Super Chief, they for the first time in the history of the world used Diesel Electric Locomotives to haul the train. They were able to shave off the schedule 15 1/2 hours, which was largely made up from the elimination of exchanging steam engines. The Diesel Electric locomotives were able to complete the journey non stop, they received fuel from fuel bins in the leading baggage car of the train. Diesel Electric technology had been developing since the 1890's in the United states and it all came together in 1934 from that point steam traction was finished it was to enjoy an Indian summer throughout the war years. The railways the world over had been in search of that technology since 1927. Once again Quinn, love your videos and keep up the great work. Regards, A Fan from Aus..
So ,,, about a 100 minute time span for engine swap on that particular run? Was it eight or nine switch outs for that run? Always wonder about the math involved.
Yup, Endmills deflect. but when slotting or cutting keyways, a 2 flute endmill won't widen out the slot like a 4 flute. Nice to see you using the right endmill. Also, could you have hung the base casting off the edge of the mill table to increase the Z space?
Hi Quinn, In Holland these " 2-flutes" are called "spiebaan frees" (key-way mill). Enjoy every episode of this project...👍 Greeting from Holland👋👋 Koos.
I've learnt a lot from both Joe Pi and Blondihacks. I haven't actually put much of it into practice, but I've learnt. They have different approaches, and that's good, I don't think that I can say that one is better than the other. They're both giving me *free* expert tuition. What's not to like about that?
@@nicholashacking381 My opinion is that there is no competition to see who’s “best”! It’s also my opinion that pie was WAY out of line to make belittling/disparaging/rude comments! It sounds like classic case of the high school bully who feels threatened. I’m a Blondie Hacker for life!
@@tomt9543 Agreed, I stopped watching him because of it. He always sort of rubbed me the wrong way with his arrogant attitude, but I watched anyway because he clearly has expertise and I could learn a lot from him. But once he started with the condescending and snide remarks it really soured my towards him. Like seriously dude, grow up and stop acting like a child.
Oh boy you are getting so close to a end this product, I am getting excited about it too. I can't wait to see it operate on some live steam...woo hoo...thanks for sharing...Vic.
Hi Quinn. I just discovered your channel from one of Mr Pete’s videos. I am enjoying your videos a lot. You may have just used the wrong term. At 15:30, you are correct about the steam pressure pushing the slide valve against the inside face of the steam chest. Since the steam pressure is equal on all sides of the valve it can still float around from side to side, so it is not self aligning but is self sealing. I have several steam engine kits to machine and build, but haven’t gotten around to doing any of them yet. I have a Sherline CNC mill and lathe.
As always, great stuff. I'm building some engines from castings without plans. The pocket determines fixed lead and lag while the eccentric provides timing. If the pocket is too wide, the engine will never run: if too narrow ? Perhaps you could help with a formula for the slide valve pocket ? I think 90% works.
1 option with regards to drilling with an odd size drill bit in collets. I have a size I needed to fit in my mill. I ground down the shank OD to fit a standard collet size. .I just carefully did it by hand on my bench grinder. But I bet a person with a proper cutter grinder could do it in a much more precise mannor. Mine works great after center drilling. Just a thought
@@Blondihacks maybe turn a collet adapter/bushing/sleeve on the lathe possibly. Or what I have done on bigger stuff when I blew a dimension, I rolled up a piece of shim stock or thin guage aluminum
If it's 1/8 inch collet, use pieces of 1/8 brass rod, put in lathe, use the drill too drill the hole in centre.. You could soft solder it in place, or simply use a razor saw to slit it lengthwise (one slit will do, ) and the collect will compress the 'tube' and grip the drill. Alternatively, you can get carbide drills for not much cash - reground pcb drills. (and small milling cutters).
“What this boils down to” at 2:26, wait... is that kitchen terminology or steam machine lingo? Lol! Either way, I learned a lot once again. Thanks Quinn!
The eccentric and slide valve configuration is actually really common on full size steam locos :) Where it gets more complicated is having two eccentrics - one forward, one reverse - and a method of combining and graduating the resulting motion between the two with an expansion link. We're overhauling a full size locomotive at the moment, the components of which look almost exactly like what you're building. Happy to send you some footage/pictures to show your viewers for comparison if you like?
A bit of a correction on the train history. There may be some direct drive diesel train engines but the majority by far are actually diesel electric. The diesel engine powers a generator and electric motors power the wheels. The big boost in power and a key advantage over steam is that you can couple multiple electric motors to run in sync so then you could use multiple train engines and pull a lot more cars. It's near impossible to use multiple engines that are powered by nonelectric motors because you just can't keep them in sync so they end up fighting each other. But you are 100% correct about the efficiency of steam.
@@Blondihacks I'll ride with "many people" since most people I know refer to them as Diesel Electric, but I know weird people so... But my point of correction was that it wasn't diesel engines getting bigger and stronger it was the ability to synchronise the electric motors that pushed the change from steam. One huge train with four engines means you can axe three crews and save som $.
I made my first steam engine out of plumbing parts and coat hanger wire, almost entirely with hand tools. You're not kidding they always run! I'll take my 15-PSI-minimum engine and take that pride you so nicely gave out. Hooray! For real though, this is coming together nicely! Where do you get the model steam fittings? That little oiler is awesome, kinda hoping someone's made a teeny injector.

Much nicer than watching Joe Pie building one.
Quinn will have to ramp up her "belittle others" game for it to be a fair comparison.
A truer statement has never been written! We love you Quinn!
I've learnt a lot from both Joe Pi and Blondihacks. I haven't actually put much of it into practice, but I've learnt. They have different approaches, and that's good, I don't think that I can say that one is better than the other. They're both giving me *free* expert tuition. What's not to like about that?
@@nicholashacking381 My opinion is that there is no competition to see who’s “best”! It’s also my opinion that pie was WAY out of line to make belittling/disparaging/rude comments! It sounds like classic case of the high school bully who feels threatened. I’m a Blondie Hacker for life!
@@tomt9543 Agreed, I stopped watching him because of it. He always sort of rubbed me the wrong way with his arrogant attitude, but I watched anyway because he clearly has expertise and I could learn a lot from him. But once he started with the condescending and snide remarks it really soured my towards him. Like seriously dude, grow up and stop acting like a child.
Oh boy you are getting so close to a end this product, I am getting excited about it too. I can't wait to see it operate on some live steam...woo hoo...thanks for sharing...Vic.
I am really enjoying this series. Thanks for sharing.
Thanks Quinn, it's looking great!
Hi Quinn. I just discovered your channel from one of Mr Pete’s videos. I am enjoying your videos a lot. You may have just used the wrong term. At 15:30, you are correct about the steam pressure pushing the slide valve against the inside face of the steam chest. Since the steam pressure is equal on all sides of the valve it can still float around from side to side, so it is not self aligning but is self sealing. I have several steam engine kits to machine and build, but haven’t gotten around to doing any of them yet. I have a Sherline CNC mill and lathe.
It is self-aligning because the steam pressure aligns the valve surface to the port face surface.
I am really looking forward to seeing what things you do with this steam engine once its done
This is my kind of video, with learning and entertaining facets.
Love these videos now I’m thinking of redesigning my seam engine that I made in high school putting a steam box on it
I’m getting quite anxious now, can’t wait to see steam,just another fantastic video ,well done Quinn🙏
It is coming together nicely. I look forward to seeing it in operation,
Wow nice to see it in motion
Wow so nice . Love to see a steam Engine come together ! You are doing Great !
I'm working on a Beam Engine it is very large model. 17 inch flywheel
As always, great stuff. I'm building some engines from castings without plans. The pocket determines fixed lead and lag while the eccentric provides timing. If the pocket is too wide, the engine will never run: if too narrow ? Perhaps you could help with a formula for the slide valve pocket ? I think 90% works.
Quinn, I'm gonna try and snipe you to do a series on valve gears. You'll especially want to take a close look at the caprotti variant.... Have fun!
With the drill press safety thing, you forgot to mention the ease of which the material cuts. With cast iron, you're not just good, you're great.
1 option with regards to drilling with an odd size drill bit in collets. I have a size I needed to fit in my mill. I ground down the shank OD to fit a standard collet size. .I just carefully did it by hand on my bench grinder. But I bet a person with a proper cutter grinder could do it in a much more precise mannor. Mine works great after center drilling. Just a thought
What happens if the drill is too small? 😬 All these drills are smaller than my smallest collet.
@@Blondihacks maybe turn a collet adapter/bushing/sleeve on the lathe possibly. Or what I have done on bigger stuff when I blew a dimension, I rolled up a piece of shim stock or thin guage aluminum
If it's 1/8 inch collet, use pieces of 1/8 brass rod, put in lathe, use the drill too drill the hole in centre.. You could soft solder it in place, or simply use a razor saw to slit it lengthwise (one slit will do, ) and the collect will compress the 'tube' and grip the drill. Alternatively, you can get carbide drills for not much cash - reground pcb drills. (and small milling cutters).
“What this boils down to” at 2:26, wait... is that kitchen terminology or steam machine lingo? Lol! Either way, I learned a lot once again. Thanks Quinn!
😇😬
Use an air tool oilier for running a engine on compressed air.
Incredibly cool. Great teaching, as always, Quinn.
11:45: in Dutch, an end mill is called a 'vingerfrees'. Aka: finger mil.
It's alive! Brilliant
This is looking great. I really want to try one of these myself.
Hi Quinn,
Nicely explained how the steam engine works... Thank you.
Take care
Paul,,
Awesome. Such an enjoyable series to watch and so very educational. I’ve learnt a lot. Thanks 🙏
Really liking this series.
The eccentric and slide valve configuration is actually really common on full size steam locos :) Where it gets more complicated is having two eccentrics - one forward, one reverse - and a method of combining and graduating the resulting motion between the two with an expansion link.
We're overhauling a full size locomotive at the moment, the components of which look almost exactly like what you're building. Happy to send you some footage/pictures to show your viewers for comparison if you like?
Well, there’s always an eccentric in there somewhere. On models, that’s where it stops.
Thanks for making these videos. I find it very interesting.
A bit of a correction on the train history. There may be some direct drive diesel train engines but the majority by far are actually diesel electric. The diesel engine powers a generator and electric motors power the wheels. The big boost in power and a key advantage over steam is that you can couple multiple electric motors to run in sync so then you could use multiple train engines and pull a lot more cars. It's near impossible to use multiple engines that are powered by nonelectric motors because you just can't keep them in sync so they end up fighting each other. But you are 100% correct about the efficiency of steam.
Yes I know they’re diesel-electric. But everyone calls them “diesels”
Also diesel hydraulics, usually in industrial settings where they don’t go far but move heavy loads for their size.
@@Blondihacks I'll ride with "many people" since most people I know refer to them as Diesel Electric, but I know weird people so... But my point of correction was that it wasn't diesel engines getting bigger and stronger it was the ability to synchronise the electric motors that pushed the change from steam. One huge train with four engines means you can axe three crews and save som $.
Quinn, the Internet is *always* angry. That's the key to its power, how it becomes a huge virtual rage monster at the drop of a drill bit. ;)
I made my first steam engine out of plumbing parts and coat hanger wire, almost entirely with hand tools. You're not kidding they always run! I'll take my 15-PSI-minimum engine and take that pride you so nicely gave out. Hooray!
For real though, this is coming together nicely! Where do you get the model steam fittings? That little oiler is awesome, kinda hoping someone's made a teeny injector.
That oiler is from PM Research. You can in fact get tiny injectors! There’s a fellow on Instagram who makes them
Exciting progress!
Coming along nicely Quinn.
