Re: Metal packing vs. stuffing box
So, Many use teflon now, but "both" variants are used after all - chord and machined rings. I have experience with both from gasoline blowlamps (They either have what seems to be cotton chord packings or (I suspect) asbestos rings. Are the machined rings squeezed like the chord stuffings or are they...

Re: Metal packing vs. stuffing box
So, I gather metal packing is more fore the non-private-sized engines. Well for sure some designs look very complex and consist of quite some pieces.
Good to know stuffing glands do the trick. But I guess they do swallow a lot of energy due to the friction, or?

Metal packing vs. stuffing box
I've found an interesting online article about the "Paxman-Lentz steam engine". https://www.paxmanhistory.org.uk/paxlentz.htm It explains in detail the working principle of the metal ring packing you can find in big steam engines. They are like piston rings around the piston rod and held in place by...

Re: Theory question: Pressure/temperature limits
I actually got sick from stick welding. It was nasty. Like heavy cramps, nausea and smelling the metal in the nose for days. Strange enough, the more I weld, the less it affects me. But whenever there was a break of at least 2-3 months, it hit hard the first time I weld again. FINALLY, I've come to ...

Re: Steam Atomizing Burner
I really love the design. Boiling free stuff is a neat idea. Here in the land of poets and inventors, getting free frying oil or engine oil is getting harder and harder, as folks get money for recycling it (which is good for the economy/people and environment. But not for my secret plans :D ) Btw I ...

Re: Theory question: Pressure/temperature limits
I am still amazed by the occurrence. There was a massive metal fire on a scrap yard in the port of a city I lived in in the past and half the city was carpeted with "poker room thick" smoke. It was advised to shut the windows and not to run around outside. (If you ever got welding fever, you know me...

Re: Theory question: Pressure/temperature limits
Yes, for the boiler tubes to have burned, they must have gotten meltingly hot so to speak. I've burned steel like that in my forge when I began forging, but the metal must already be glowing almost white. That shouldn't be possible in a boiler, even if the tubes are empty. But if they reached red ho...

Re: Barn find
Interesting the stepped Stevenson gear. The gear is used for the rough setup and the governor provides for the fine-tuning.

Re: Theory question: Pressure/temperature limits
Bart, your poetic words put pictures of link gears and glistening spring waters in my mind. I have literally never heard of a superheater ending up being a metal fire. That's some chemical reaction. It reminds me of a german experimental locomotive. As is tradition in Germany :D , it was over-engine...

Theory question: Pressure/temperature limits
Hello, Doing the never-ending researches, I've been wondering how much pressure and temperature a reciprocating steam engine could actually work with. I remember watching the Jay Leno's Garage videos about his White, Doble and Stanley steamers and I was actually surprised how much pressure/temperatu...
