THE TROUBLE WITH OLD STEAM LOCOMOTIVES - PART #13

[@ratheonhudson3311]

"Measure twice, cut once" is a phrase that brings back happy memories for me. That you for this video and for making my day

[@160rpm]

Again, nice to see I'm not the only one that also draw marks over the ruler haha

[@claywright9118]

Keith, have you checked the piston ring end gap? That is if you insert the ring into the cylinder to see if there's any gap? if none, consider about .030" or .07mm. That could be why it's tight with the rings on, or the depth of the piston land is too shallow. The rings need to be able to "float" in the grooves (lands). And then the "couple thou" clearance might be troublesome, the piston would expand first when heated, the cylinder and valve chest would take longer to expand to a normalized temperature due to the mass. Ok, end of keyboard warrior mode, back to steam geek. Keep up the good work!

[@keithappleton]

Thank you for your advice Clay, I did all of that, and I am about to voice over a video explaining what I did }:-)))

[@Tocsin-Bang]

Used to hate fitting piston rings on motorbikes. No such thing as cable ties back then. We used a split tin can and a couple of lengths of wire.

[@billyjack8119]

Ring groove not deep enough? Maybe rings butting on the ends with no gap? Seems strange they would cause too much drag like that if the first two are correct.

[@davidgandar2021]

Do you heat-treat the piston rings to make then less prone to breakage. Manufacturers of replacement rings for car and motorcycle do this and it works.

[@keithappleton]

No, they were fine as they were .....

[@alfredorocca8958]

Complimenti!

[@sargepent9815]

Not a machinist, but is the groove for the ring deep enough? Sometimes tolerance is pretty tight and another thousandth or two deeper groove might be the difference. Or, is the bore if the cylinder out of round? I have seen this in petrol engines and discovered the issue when fitting new parts that don't match the worn bore. Interested to see the results. Cheers

[@keithappleton]

The cylinder was under size.

I had a choice at School between Technical Drawing or French. Dad made me struggle with French. Years later chatting up 2 French Girls was done superbly in English. I used Technical Drawing from A Level... During My Design Degree and all through my working life and Hobby!!!!! Love David and Lily. I have no Clew pit of what you are doing!!!! Joke.

[@collingeiger7321]

I understand the struggle of getting the cast iron piston rings on, taking them back off however, I feel like I would find that to be rather difficult.

[@keithappleton]

It is almost the same technique as fitting them in the first place . . .

[@amanofmanyparts9120]

@@keithappleton Sliding a feeler gauge under the first free end helps. With care you can move it around the ring to get it all the way out without breaking it.

[@boyd21]

Won't the cast iron ware in?

[@keithappleton]

Not really if the cylinder is not very smooth to start with. . . {:-)))

How can you say that Latin is not useful! Imagine the lovely chat you can have, should you ever bump into the Pope at your local supermarket.

I wish I HAD taken Latin....so many words in English would make more sense,not to mention medical and legal jargon!

[@sevensprings460]

David Ahtes The only Latin I know is from the movie “Life of Brian” which I wish was on tv considering it’s Easter.

[@amanofmanyparts9120]

I've heard it claimed that if you have a good grounding in Latin, it makes learning any of the Romance languages easier. Dunno. I still struggle with English!
