Machining a Model Steam Engine Cylinder - Part 2 - The Oblique Port Holes

[@ziggythecartoon]

I love your board breakdowns. They really help me better understand how to do what needs done. Thanks for passing on your knowledge.

[@joepie221]

Be sure you pass it on too.

[@bobtherat99]

I always appreciate the chalk talk. It really helps my visualize what you are doing.

[@outsidescrewball]

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

[@peterfitzpatrick7032]

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... 😎👍☘️🍺

[@jevans4379]

Your ability to draw an explanation is unparalleled. Thank you.

[@JohnSchirra]

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.

Never heard of a tooling ball before - thanks for introducing that. The paper in the port trick is a good one too!

[@rockchoppers8118]

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.

[@delucain]

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.

[@peterparsons3297]

[@mr.t.807]

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.

[@jd70HJ19]

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 .

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!

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.

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.

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.

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.

Nice work, by the numbers. Always admire the way you quite clearly explain the geometry then reduce the set up and machining to 'just by the numbers'. Always learning something from you Joe, thanks.

Great feedback. Thanks.

Funny you know, I'd never even heard of Tooling Balls before. I went looking through your back catalog and found a vid I had missed for some reason a year ago on tooling balls and tooling holes. You're a good teacher Joe, better than I had through trade school. Thank you, keep 'showing us what ya got'.. please.

Ps, I'm trying to buy a few Tooling Balls, a bit thin on the ground here in Australia, somewhat like rocking horse .....

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 !!
