How to make Clupet Piston rings. 

Awesome work, never realised how simple it was to do :) Got the tunes on in the background too!

Brilliantly simple or simply brilliant.😮😮😮😮

Nice to see informative workshop videos like these, don't have to be hich tec production type, just helpful videos showing us how things are done. Great stuff !

Many thanks for this clear explanation. I have wondered for the last 40 years how these were done. It seemed to be a dark art secret with only a select few practitioners.....now everybody knows. Thank you.

Thanks guys, to be honest that has not cleared up any mystery for Clupert rings for me. Instead you have now created a need and desire to understand more about this subject 🤔 Very fascinating to watch from someone who has never heard of these. Good video. Very well explained and demonstrated even for a numpty like me. What I did like was none of the usual erm erm erm or the American version hohm hohm hohm that just fills most videos these days rendering them impossible to watch. Excellent British craftsmanship. I liked it 👍👍👍👍👍 a lot.

Fascinating! Always wondered how they were made. I have retired to Thailand where I'm building a half-sized Little Samson Traction Engine with Clupet rings that I bought in UK. Now if I break my rings when fitting I know how to make another one without needing to await delivery from UK. Very comforting.

Just proves why they're so dearer than a standard ring. That's a lot of effort.

Hi Simon and John, absolutely perfect video for all us amiture hobby machinist. Please, please keep doing them. After having to take a long absence from my hobby whilst having a child and doing major rebuild work on my house I can't wait to get my machines back out of storage, set them up and get back to my GWR mannor engine I purchased as a part build some years ago for you. Hope your all well, and hopefully see you about the events now the Pandemic is kindly coming its closeure. Phil in Cumbria.

Excellent video chaps and much appreciated.

Hello Simon & John from the steam workshop. ; > Fantastically educational.

Outstanding!

Nice work lads, good tutorial - thanks for sharing.

Thankyou for sharing this gem!

Really interesting, thanks!

This was very interesting! Looks like it is tough on the fingers.

Beaut fellas, Thank You.

Totally EXCELLENT thanks Lads!

Good show well done.😎

Thanks for sharing 👍🏻

Did Mr Appleton inspire further video making or was this spontaneous? either way very informative!

Very skilful.

4:08 bless you

I assume this would be possible with a plastic ring, say made of glass filled nylon or maybe the molybdenum disulphide impregnated stuff.. well, other than the part about hitting it with a torch anyway!

Would you use only one Clupet ring as apposed to two standard rings, or would you still use two Clupet rings?

Ask Keith to help you next time there could be a problem about rebroadcasting music!!! Otherwise fine and I am off to make some!!! David and Lily.

I bought one for my last steam engine, but now I will be making them from now on! How small can you go with these?

How much plus of the bore size do you make the OD of the rings , .010” or so ?

Any tips for getting rbe ring on rbe piston? I keep breaking them.

Simon & John, Can you make and sell 2.625" rings for my 2-8-2 Mikado engine? Thanks!

Has anybody done this without having to go inside out it b4 heat treat, just machine it a little bigger, but heat it in a thick jig that forces it down maybe a jig within a jig so it can get off what it's clamped down and heated on?

Informative! May I suggest, next time you film, turn off the distracting radio in the background. For a really posh result, you may wish to place microphones on all speakers, so that their voice isn't a muffled jumble of sounds! These are trifling issues and I do hope you take them in the spirit intended

I THOUGHT MR CRISPIN WAS GOD.... BUT NOW YOU'VE SPOILED IT 😢
