Machining a Model Steam Engine Cylinder - Part 2 - The Oblique Port Holes
Вставка
- Опубліковано 15 вер 2024
- This video is the completion of the model steam engine, 'cylinder' component. The oblique, port holes, may look scary, but the approach and mechanics don't have to be. Let me show you a rock solid way to accurately set it up, and confidently machine it, using a "Tooling Ball". A valuable skill you can apply to other projects. Take a Look !!

I use to read about “tool maker buttons”...but never saw/read any demonstrations....I asked my mentor Chui....WHY???...His response was TOOLING BALLS.....THANK YOU for a great explanation and demonstration of the use of a TOOLING BALL, in reality Simple/Smart with triangles...viewers will be surprised how expensive they are
Toolmakers buttons are a different animal , they are used for precise coordinate boring on a flat surface...
Basically the bore centres are marked out then drilled & tapped for a small screw...
Then ground bushes are affixed with the screws and washers...not too tightly..
The bushes are usually a nominal dimension (0.500" say ) & they are adjusted (nudged) by measuring from the workpiece edges until they are perfectly concentric with the required coordinate, the screw is pinched down... then the bush is swept to centre it under the spindle.
The bush is then removed and the hole drilled and bored.
I have used this procedure on a lathe faceplate for boring accurately spaced holes in the lathe...

I love your board breakdowns. They really help me better understand how to do what needs done. Thanks for passing on your knowledge.
Be sure you pass it on too.
I always appreciate the chalk talk. It really helps my visualize what you are doing.
Your ability to draw an explanation is unparalleled. Thank you.
I appreciate that.
This episode removes all doubt! You are really on the ball.
Good one !!
Only one question, who would click thumbs down on this? Great video, Joe!
Blondihacks' channel has been working on this exact steam engine for over a month now. Joe just released these two videos working on the VERY next parts she was going to release videos about, skipping the earlier components in, what seems like, an attempt to purposefully get ahead of her. He's aware of her channel and this project, because he posted a response video to her fixturing of the baseplate of this steam engine. He doesn't reference her directly, but it's mentioned in the comments that there was some kind of disagreement between them about it. I don't get the impression they're friends. So, this feels like him intentionally trying to screw her on this project. Maybe I'm wrong, but it doesn't feel like I am.
always someone, wonder if they can do a better job.... i doubt it
Extremely appreciative to learn from this master at the beginning of my machining career at 57 yrs old I prolly don’t have another 50 yrs to learn my own self.
If pictures are worth a thousand words Joe’s videos are worth a billion.
Thank you so much Joe !!!
When will schools adopt this theory 5 min of video could save a month of class time.
Reminds me of a year of memorize this periodic table instead of if you need the periodic table it’s in this book on that shelf lesson over 2 min lol.
You're an amazing teacher. Im a gunsmith that learned from my father who was a tool and die maker for 42 years but he didn't explain as well as you do. I also appreciate your volume of videos that you put out. Keep it up.
A million miles away from the LBSC method. This series is going to be the ultimate accurate way to machine a steam cylinder. Mind you the old drawings always left out vital diamensions and covered up that fact by saying something like 'machine to suit casting'. Really enjoying these videos Joe.
Excellent presentation as always. I took a year of machining classes at a local technical college when I took up machining as a hobby. They did not teach these techiniques in school. There is no way for me to learn this stuff unless without a mentor. You are doing a great service to both hobbyists and professionals.
I am moved by your comment. Thank you.
Joe, thank you for showing the use of the Tooling Ball. I've read about them, but this is the first time I've ever seen one being used. :) Thanks for sharing!
Glad to help
Incredible information!
My man . THE BLACKSMITH is here. Good to see you here.👍
Glad it was helpful! I watched a few of your videos and just subscribed to keep the source fresh on my list of craftsman. be safe.
Indeed great video just watched part 1 very informative.
You have another sub too!
It's a nice change of pace to get a project instead of just tips and tricks! 😊
thanks. thats good feedback, but hard to do in a business shop.
@@joepie221 I absolutely understand that. I'm really enjoying this project, thank you.
Hi Joe, thanks, I did n't even know about tooling balls. Well, the ones you are talking about! Beautiful explanation and demo. Guru level. BobUK.
Another Master Class! Your demonstration of the use of the tooling ball was extremely helpful, not to mention the dual vise setup. Your videography is appreciated also. I’m sure it complicates the task at hand but your camera work is very helpful in understanding what you are trying to demonstrate. Nicely done!
Thank you very much!
Would you like to make a request on the next part done?
Your choice, the base, the crankshaft, or the flywheel.
Never heard of a tooling ball before - thanks for introducing that. The paper in the port trick is a good one too!
Beautiful!! If you don't have one make one. A great rule to live by.. Great to hear the natives are restless. CHEERS and stay safe.
That sound never gets old.
This series is fascinating on so many levels: math, machining and model making...I am learning so much! Thank you Joe
Lovely work. When you see others trying to do the same thing, It is clear that experience and expertise cannot be beaten. Thanks for sharing both.
I have a feeling we will get to see more of both.
I’m loving the different approaches here and with “Blondijacks”. Both great teachers.
She does well for a part time garage amateur, but proceed slowly and be safe.
This is why I subscribe to Joe's channel...
Much appreciated.
My father was a tool and die maker , I did not follow in his footsteps and retired from a career in combustible fuels energy production.However to this day machining still fascinates me , having for decades watched my father produce some very complicated parts during his career.
Building these models is pure passion and the desire to meet the challenges of machining a rough piece of metal into a functioning device , it cannot be for any other reason . A finished model would be unaffordable if resale was the only motive for anyone that invests so much on specialized equipment and the dedication to accomplish the task with as near perfection that may be possible. Striving for excellence and perfection is what most machinist have in common irrespective of being a hobbyist or a professional . Very nice work sir, in fact , excellent work .Watching your videos brings back many many great memories .
I appreciate the comment and story. Thanks.
I was really looking forward to seeing this done in your usual precise manner. You are a professional machinist which very few can match or even come close. Professional in every sense; concept, visualization, planning, setup and execution. A pleasure watching your videos, every one. This one was excellent. Excited to see the remaining segments.
Thank you for this video. I have done it with a lot of luck involved. I like the math version. No one has explained it in this manner before. Again thank you and it shows that you use the smart way of doing things. I hope Blondiehacks is watching!
Very nicely demonstrated, and explained.
I think you're enjoying doing this little steam engine.
It's also a great teaching aid, full of all kind of steps to get to the finished product.
And it well run after your done.
Skill level : tangent of genius.
I can see myself struggling for 8 hrs and still throwing that part in the scrap bin.
Hats off to you.
Thank you very much.
Another brilliant video Mr Pie! For the most amateur of amateurs such as I, your easy to understand descriptions and set ups of difficult operations make this machining world much more accessible. Sincere thanks.
Glad you enjoyed it
My favorite part of these is the anticipation of problems:
I don't know how this will feel breaking through, so I put this piece of paper. Or the various points where something was done to "avoid blowing up the cutter."
One can only think that a very young Joe Pie must have a wonderful bloopers tape showing the hard-earned experience that resulted in so much wisdom. It's great you're now saving others having to learn the hard way.
I was ready for part 2! Thanks for all the great content. Your experience really allows you to make it easy to understand and think about the problem at hand.
Tooling ball. What an elegantly simple way of finding the center of a hole at just about any angle. Gonna have to get me one. And as always, breaking things down into right triangles helps (or at least helps me).
Wow! There's a lot of machinist gold in this one. I'm glad I paid attention in geometry... too bad I don't remember all of it after 44 years of "other stuff". I remember more than I thought. I have never seen a tooling ball used but man... what a great tool
There are plenty of apps and little books for us FOG's
Always helps to be smarter than what you're working on. A lot of the geometry and trig we learned in school can be applied to most projects like this. Looking good
That tooling ball fills in a BIG hole in my knowledge base!! I would LOVE to see more examples of how that can be used!
Joe has a whole video on tooling balls. He tells you how to use them and which kind to buy.
@@MichaelMoranGearHead Thanks! I just found it. ua-cam.com/video/FnEl6Kj-F-E/v-deo.html
They already make at least five appearances in existing videos, but there are not too many actual demonstrations.
Thanks, Joe! I probably would have missed that paper trick. I also tend to overlook the value of fixtures like that tooling ball plug; especially for one of parts.
I love all the gizmos they use for aligning and orienting parts along with the trig to define the measurements for placement. Raise your hand if you ever heard of a “tooling ball”! Seems pretty obvious after you see it but somebody got this done without having seen a Joe Pie do it first. Gotta love smart people. (Is this where self loathing comes from? :-) )
Ya gotta have balls to make it in this trade.
Not to mention a wiggler....
Great segment Joe. Loved how you broke down and explained the math behind the setup. Great result!
No guess work on this one. Glad you enjoyed it.
Thanks. I've seen photos of tooling balls for 60 years but never seen one used until now. I learned some interesting stuff today.
If it was from me , ya just made me proud.
@@joepie221 It was from you indeed, and I'm proud to be a subscriber. Thanks for all the good stuff you present.
It's 12.30am here in the UK. I should be asleep. I intended to watch 15 minutes of part 1. I've just seen the end of part 2.
I was glued to it. A joy to watch. A real treat. Thank you.
Now get some sleep. Glad you enjoyed it.
Y'know, Joe: watching these videos, one gets the distinct impression that you have been doing this sort of thing for a while. I spent three years in high school machine shop, and learned less about machine work than I have watching a few hours of your videos. Well done.
First shop exposure 1971, fell in love with machines 1971, Technical curriculum high school 1972-1976, Full time machinist night shift 1975-1976, On the job working apprenticeship 1976-1980, full time prototype machinist to 2005, opened my own shop in 2005- present. 48 years hands on in aerospace, semi-conductor and orthopedics. I'm still not sure its what I want to do when I grow up. :) Thanks for the comment.
@@joepie221 Had a good laugh from You mentioning not knowing what to do when growing up... Being of rather similar vintage as You. That's exactly what my wife tell people asking what I do. Have been making a living running my own business since the mid 80:s and never looked back. Very interesting video as usual!
I always learn something new when I watch your channel. Thank you for all the great lessons. It is so cool to watch a master do his thing, you make it look so simple.
Glad you enjoy it! Thanks.
Awesome Joe theres alot of info in this video that I've never seen before......this is why I watch UA-cam but good content like this is hard to find
Loved the video, great information, easy to follow, liked the part about using the piece of Paper, simple but effective, Thank you.👍😀
Its good to see it wiggle.
second time I've seen a tooling ball used. Time to buy. Thanks Professor Pie. Crystal clear.
I am not a machinist, but I enjoyed watching these two videos. You explain what you are doing well. I wish I knew about this profession decades ago it looks like an interesting job to have!
My journey has been fun. you have to pick a good line or it can be rough.
Thank you again Joe - I have actually done a fair few of these and I learnt a number of things from your example. Years ago I learnt a lot from watching the likes of Keith Fenner, Tom Lipton and Adam Booth, recently however maybe not so much. Your content however teaches me something new most every time I look. The trick with the paper was a DOH moment for me. Not to say I agree with everything - that milling cutter down the bore nearly did for me. Thanks again. Paul C
"Look how nice n straight that is. Almost like I knew what I was doing."
Thank you BOSS
I'll come to your class, first and last, everytime.
You continue to educate. Enjoyed watching it, watched it twice.
Joe, I have to send my hardy thanks to the viewer that gave you this model. I have learned a lot so far from this project. Obviously, trolls don't want you to have a perfect score. I bet they don't even watch these videos. They just click thumbs down as soon as the notification comes in.
Thanks Joe, I've been doing this fifty years, but never had modern schooling. The use of the tooling ball was valuable information I didn't fully understand until now. I came at it as a mechanic, doing engine machine work, and only working my way to a regular machine and welding shop. The math explanation was clear and easy to understand.
That’s great!!! Once it’s drawn up and explained everything falls into place. Thanks joe!
Accidentally found your yt channel and I’m hooked. I am studying mechanical engineering (graduating December) and part of our curriculum included the machining of a small air engine. I enjoyed the hands on experience and the tricks and loops machinists use to create complex features. Now as an intern at an analytical instrumentation company, I design a lot of machined parts and really try to think about how to design parts to make them functional and as simple to manufacture as possible. I was amazed at how easy you make this look, your knowledge is truly invaluable. Can’t wait to see more!
Thanks. I'm glad you stumbled across this channel. I'd done this my entire working life. Coming up on 48 years now. Hit that subscribe button and pass it around. If you have a question, go ahead and ask.
Joe, there has been a tooling ball in my tool box since I was an apprentice in the early 1960's and to be honest I had no idea what it was. Thanks for the education! I can't wait for a chance to try it out, possibly on my next steam cylinder. I have done 3/4 live steam locomotive cylinders and two PM research cylinders and also a cylinder in clear Plexiglas to show what the drawings, some not as great as the one's you are working from, are trying to convey about the steam passages to someone starting out.
P.S . my experience is the drawings pass muster both on the steam engines and the small machine tools like the shaper and drill press. the lathe or mill will be next.
Well Joe, i thought i knew a fair bit about machining after 40yrs....but you make me feel like an apprentice!
We can all learn something from each other.
Thanks for sharing! That is so much easier than the way any other modelist has shown. It's nice to be taught by a professional.
Brilliant....just brilliant. The use of the second vise...genius. After watching your videos, I always say to myself - "Why did he do that way?" Then I ask - "How did he do that again?" Quickly followed by - "Ahhh that is why he did it that way!" And then finally I swear at myself for not thinking of it. Many thanks Joe! I always learn something from your videos!
Glad to be part of the learning curve. Now pass it on.
Really nice job Joe. That's the kind of job that gives you the gray hair.
I never saw one with the two ports. Both of mine have a single port and the cover holes are sixty degrees from yours. I'm loving the duel port idea.
You are LONG overdue for 100,000 subscribers! Another fantastic video.
Thank you, I'm So close! Statistically, over half the people that watch my videos and leave comments have not hit the subscribe button. This channel gets over a million views a month. It would be an awesome 'Thank you', if even a small portion signed on. Its actually a lot of work to shoot, edit and present these videos.
@@joepie221 Every one of your videos is a gem. Thanks for persevering. We all need it!
Your setup drawings are very nice. As someone who learned on a shop floor with no computer, being asked to make parts with compound radii/angles, and given very few print dimensions... Well I appreciate a nice diagram showing the derivations. I always enjoyed having a well layed out and defined problem.
Thank you very much!
You made the very Complicated, very easy to understand for this beginner. As always thank you
You're very welcome!
I have a steam engine of the same size that i will be starting it will be my second one and vids like this will make the next one much easier. Thanks for taking the time.
Great job. I built a Tiny Power M side crank with a Stevenson’s reversing link ten years ago.The cylinder and steam box are separate castings and the ports are cored,making the machining much simpler. The original prints used 5 ball bearings.Mine has 21 bearings.(I hate to oil bushings ). I had to really pay attention because,the prints had several mathematical errors. I had this 200 pound monstrosity sitting on the kitchen table,adjusting piston height,eccentrics,etc. I told Barbara, I guess thats about the best I can do. I hope it runs.She was more confident than I was. I hooked up the air and opened the valve. I stood there with that deer in the headlights look when,it sprung to life.It will run slow enough to count the revolutions and,reverses like a 3 phase motor at any speed.It is not practical but, it was surely gratifying to build. I am looking forward to watching the progress.
Your explanations are always clear and concise. Those unfamiliar with terminology will have no problem understanding your theories and actions. Always great videos. Thanks for sharing Joe.
Glad it was helpful!
It is always a pleasure watching you work
Just discovered your channel...and learned a whole bunch...subscribed!
Welcome aboard! thanks for assisting in the final 100K push. I have some good videos. Feel free to ask if you look for something and can't find it.
Congratulations.Theory and reality work toghether.No need for trial and error.No need for a second chance.Thank you.
Very informative, introduced me to tooling I don't know existed. Thanks 👍
Glad it was helpful!
Another setup I never would’ve thought of in a million years... I’m always learning on this channel. 👍
I appreciate your continued and positive comments.
That 21 minutes just flew by...... great vid!
awesome video. i always learn a lot from your instructional vids. thank you sir!
Brilliant planning and machining. You are a great teacher!
👍👍😎👍👍 - Joe, hope you're having as much fun recording these as we are getting to watch the master at work. Thank you
Engineering on a different level! As always incredible 😊
Thank you very much!
Thank you for so many great tips. It is fun to watch you work!
Joe-
Great, informative series. It is so worthwhile to follow your thought process re planning and sequence of operations as you proceed through this project. Your time and effort put into the filming and explanations is greatly appreciated. Keep ‘em coming!
Best regards-
Bill
thanks Bill, it truly does amp up the difficulty and time it takes to show the process.
The paper trick was clever!
I knew you would like that. Toothpicks or wood dowels can be used for deeper holes.
love this channel. Keep up the good work, Joe!
Hit that sub button and help me hit 100K
Great camera work Joe, and learned that I have a centering ball that came with my SB lathe tooling, but did not have a clue what it was till seeing this video, 👍👍
Dear Joe,
thank you very much for posting this. I have only never machined a steam engine cylinder but a pair for a small locomotive are on the to do list. I have read numerous instructions and most involve much use of the four jaw chuck and often because the articles were written when many model engineers did not have a mill at all. None of this worries me bar the steam passages and your explanation has given a degree of certainty that I previously did not. Thank you. I do not like guesswork either.
LOL, I haven't messed with math like this for over 30 years.Good thing I still have my Gr 10 through 12 math notes and books eh. Thanks Joe. It's always a pleasure my friend.
That tooling ball is, as they say, a real "Keys to the Ferrari" tidbit!!
Joe, masterfully done!also an example of why i designed a steam cylinder to assemble from "shapes" , in h.s. sophimore year. but i was going to drill the steam gallerys "strait", and catch the flanges/ports. but i got inviolved in my "machine-x" dutys. i was advancedi took machine 2 and two periods of "x" that year. from looking at that casting , and how clean it machined. it MUST have been heat-soaked.the finish in the bore is so nice. can hardly wait to see more of this project! poppy's workshop says HI
I like the way you think. A little bit of math makes jobs easier, faster and more accurate. I try to teach my apprentices to have that mindset. Thanks for doing these videos. They help a lot.
Show your apprentices. Light that fire !!
Wow. Another fantastic teaching video. The part is beeeyoooteeful - crisp, clean, and visually perfect. This sort of teaching video really helps me up my game.
Glad you enjoyed it!
Joe, thanks very much for these videos. I wish stuff like this had existed 20+ years ago when I started building model engines. My scrap box would have been much less full! I've learned a lot along the way, though.
Lots of great info - and the tooling ball is the cat's pajamas :)
You need some math, but its the correct way to do it.
I build Stuart steam engines....just starting my third - however its great to watch this and see how you do things. Always stuff to be learnt! For example - i never knew about those tooling balls. Thanks for the video.
Glad to help
Picked up quite a few tips there. Thank you Joe.
Good to hear from you Kyle. I hope all is well. thanks for watching.
Nice job. I had heard of tooling buttons but not a tooling ball. The trick with the paper in the intake port was a good'un too. Thanks for sharing.
Regards,
Mark Presling
thanks for stopping by Mark. I now have your sticker on my wall of fame. It sits at about 2 O'clock.
@@joepie221 Cool! I'll be looking out for it. Thanks a bunch. Keep the steam engine videos coming.
I drilled and tapped my cylinder before the head cap. I then used transfer screws. What a PITA. 5-40 transfer screws. I got one drilled wrong, got frustrated. Went to the dro, marked and drilled like I did for the cylinder, the head cap fits perfectly.
You show us the way Joe!!
hit the numbers guys. Standards exist for a reason.
that was really good, I never saw a tooling ball used before
every top machinist I've ever worked with shakes like that, must be all that knowledge
Hand me a .357 and see if I shake.
Always nice to watch how you think and use your experience to get the job done!
Glad you enjoyed it!
Great video and machining, thanks, Joe!
Thank you very much for the very clear, logical explanation and demonstration. You make it look easy! There is so much information in the last two videos that I'll have to watch them again. The only thing that bugs me is the nick out of the end of the valve chest from when you cleaned up the end of the cylinder! :P
That casting mis match is the only blemish on this thing. I like the raw finish of the casting, so I may choose not to blend it out.
I'm not a model steam engine guy but the techniques that you are teaching are certainly interesting! Keep up the awesome videos!
Thanks, will do!
These tooling balls you speak of, this isn't the first time you have demonstrated their use. In my boring, 90 degree flat plane world I never seem to do anything that would require them.. But I have filed this information away for the day I do. Perhaps I should get a couple and place them in the drawer with the edge finders so I am constantly reminded and don't forget about them!
I remember back in the late 70's an old timer I knew always told me It's not so much what you do, but how you go about doing it that will make the difference. The techniques you show us Joe are not always obvious, but once you point them out they sure make sense. It gets me thinking every time I do a set up. Thanks for taking the time to do this Joe I know I appreciate the effort.
You will need a bank loan to buy one.
They aren't that expensive. Buying the mill so you can use it will annoy the wife though.
Joe Pieczynski I could not find them here in Australia so I had to buy from USA. $ 100 plus $ 50 postage. By the time it was converted into Australian Dollars it was well over A$ 200. Still have not used it yet nor the setup tool I purchased from you. Just in stock in case I ever need it.

@@daveticehurst4191 Tooling balls this size are about $25 here in the US at McMaster-Carr. Shipping to Australia is about $40 for a small flat rate box. Exchange rate will increase that but not to $200.
As always bunch of great tips 👍 Thank you, I am feeling like I am getting smarter with each and every of your videos :)
All I can think of while watching this is - Gee, sure is easier to just do it right the first time.
Love your work.
Nah, do it, make a ton of mistakes, don't point them out, then shoot a tutorial and show 45000 hungry minds how to do it. Just kidding. Thanks for watching.
Great Job, New centering approach with the ball plug! Thanks for sharing Joe!
You are a smart man Joe Pi...
