I was thinking initially that you would be using a boring bar to perform the part but I really was pleased to see trepanning, an underrated technique these days. I should have guessed that a thrifty Northerner would not turn a very handy remaining piece of stock into a big pile of scrap in the chip tray!
@@howardosborne8647 This is why northerners invented multi-cylinder engines. The piston rings get smaller each time so you need more cylinders for the same power.
@Ray Hathaway, here's to another 48 years of you slinging chips! There's nothing like manual machining, many moons ago I had the pleasure of visiting the JCB factory and watching the 5,000 tonne press chop through 1.5" steel for the chassis. The ground shook when the press came down and the press was embedded 30' into the factory floor but the thing that really got my juices flowing was the friction welding of the hydraulic rams. Rotating the cap against the tube under extreme pressure, very impressive.

I discovered this channel via a pro board Model Engineering forum. What a find! Clear and concise explanations of how to do stuff, combined with an excellent balance of wit and humour. I am a 66 year old newbie, and I am learning so much from you young sir! Thank you.
Well done, Sir. Not only were the trepanning and trumpet chamfering excellent ideas, but you can now sell the rest of the stock to another Yorkshireman who wants to make piston rings for smaller pistons. Bravo. I jest, of course. Watching the way you work is an education. Don't know whether the humour or the machining is the best.
Excellent video, I don't need piston rings at the moment but I am going to try each of those machining techniques. I learned alot. Thank you Mr.Crispin for your time
I am 67 years old and I learned something new today. I like your attention to detail and the way you describe the process. Nothing is getting omitted. Somebody can actually follow your process step by step. When I compare your instructions to HP network printer setup guide, you win without any questions.
As an engineer myself I can say thats a brilliant tutorial on how you made piston rings, never had to make piston rings myself yet but after seeing this I now have a better chance of making them if I ever need to make some.
Another interesting and entertaining video sir! The thought process was excellent yet again and the parts produced look fantastic. The night cap had me in stitches. I had to watch that section again to hear what you were saying. Keep on keeping on.
Thoroughly enjoyed the video and learnt a lot. I just knew you would have a matching night cap, its the attention to detail that makes these videos worth watching.
This is why I watch YT. I'm not going to make a steam engine or a single piston ring, I don't even possess a decent set of drill bits, but this is absolute gold, thank you for the effort you put in.
An excellant demonstration about aii the details of piston theoretical and practical . Even a lay man can understands easily. Thanks a lot to dear demonstratrator .
Interesting techniques, Mr Crispin. I especially like your hat boomerang tossing method to get it to land on your drill press every time! Thanks so much for sharing.
Hello Funny man with a hat. Difficult to understand your English last years but today after seeing many time all your so great videos, my ears are understanding perfectly everything. For me You are in the top 10 of the world best who have help me so much since 2 years I bought my machines. Joe P and Keith R are also Kings of mécanique like you. Thank you so much from a french Old man.
The hat bit never gets old! Clever work on these piston rings - I've come away with at least three things I might be able to put to good use one day. Thanks!
Show of prepared devices in the workshop and material savings. Most importantly: exact measures for the clearance to expand within the cylinder controlled by contraction after cooling the entire assembly after heat treatment on a pre-calibrated internal base. The entire process consisted of very intelligent machining. Grateful for the video Mr. Crispin!
I’ve been in engineering and machining of one type or another all of my working life. I’ ve seen this, done that, and got the T shirt, but I learn something new in every video from this guy! Thank you for taking the time and effort to produce these educational lessons.
Am I a homeshop machinist? -Yes. Did I learn some very effective techniques to add to my quiver? -Yes. Am I ever going to build a steam loco? -No............... (not in the next 20 yrs) Am I very grateful for another excellent Crispy vid? (and I do mean Crispy) -Yes Did I giggle my arse off from the trademark dry humour? - Undoubtedly :) Don't stop MrC, you keep me going, outside of the workshop.xx Thank you.
... Mr Crispin, I have very much enjoyed watching your videos. I believe I have watched them all, alas.. Such accuracy ! ... such precision ! I admire the geometry and the logic of the procedure. Also, the pieces you produce are quite beautiful. Thank you.
Not a machinist but watch quite a few, and this is a seriously under-rated channel. No click-baiting, dramatic intro sequence, begging for sub/'Hit the Like Button; etc, etc. Humor is unique yet not indicative of a repressed comedien yearning to break into the big time, and simply quality informative work thats explained properly without being too dumbed down nor journeyman jargon. Subbed of course.
NIce work MrCrispin ! I like the way you do it, as well as learn and enjoy. Good jokes too, but I especially like the 'annulus riser' ! Keep on and keep well.
I am very impressed with the setup. I hate seeing stock wasted and you did a superb job of avoiding that. Thank you for the excellent video. Stay warm.
This is great, machining in a shed is my favourite thing and this making bits for a steam loco is just the cherry on the top. Ive found a new channel to subscribe to and watch, thanks Mr. Crispin!
Built three locos in my days, one using the Springbok boiler. Also done cast iron rings, but your method of "cracking" the rings left me in awe..superb.
Another winning video from Mr Crispin, some more very clever thinking (and machining) in making your piston rings. I do enjoy watching your videos on making your small gauge locomotive engine, it’s fascinating to watch how you meet and overcome the particular problem in hand. I like (as do many other people) wait for your next video and seeing the coming piece in your workshop . I wish you the very best wishes for 2021. Phil
Meehanite ! Now there's a word to remember, all the way back to 1962 when I started technical college which at the age of seventeeen was the beginning of a life in Engineering, still active sixty years later. My first motor car was a Riley one and a half, RME saloon, which had a number of components made from Meehanite, brake drums, and even the cylinder block. They were very high quality cars Rileys, and the chassis was as strong as a JCB earthmover. I spent every Saturday morning greasing the abundance of nipples thus ensuring long and reliable life by preventative maintenance. I am presently designing a unique zero carbon power plant for the Isle of Man, which at sixty months contract duration will probably be my last big job. Great to meet fellow Engineers online too ! Keep the chuck turning !!!
33:35 lol. Great video as always. Really nice to see some of us Brits in sheds on RUclips - Good as they are (and some really are astounding video productions), our friends across the pond with their factory-sized and equipped "home shops" do sometimes get a bit carried away and seem to lose sight of demonstrating doing something as a hobby! 🇬🇧🇬🇧
I like your different approaches to various problems. Very informative. This channel makes me think of Keith Appleton and his channel regarding steam engines and shop practice.
Very nice. I am enjoying your work tremendously. I am happy that you saved some of the Queen’s Ransom cast iron plus, I anticipated you returning in your PJ’s. God bless!

I watch Joe Pie & Stefan Gottswinter & This old Tony with considerable Respect, but this video just glazed the cherry that's on top.
As a fellow Yorkshireman, I believe the main reason for this wonderful method is so you don't waste the core !
Trepanning and you still have most of the iron left. Brilliant!
The less wastage the better. That'll be music to a frugal Northerner's ears.
@@howardosborne8647 This is why northerners invented multi-cylinder engines. The piston rings get smaller each time so you need more cylinders for the same power.

The trumpet chamfering technique was particularly clever.
