Re: Vintage Steam Engine.

Ah, good old technic. I like engines with a one-sided slide and a rod stay opposite the slide.

Re: digital steam engine indicator

Yes, I think it can be extremely useful to be able to see a real rime P-V-diagram to learn how the engine is fairing and to see how the conditions inside the cylinder are changing along a revolution. I am actually already thinking about a later upgrade to save the data of an entire trip onto a SD ca...

Re: digital steam engine indicator

Sooooo. I think I've finally succeeded. The programs work and I am now just streamlining them to make them as usable as possible for a wide variety of uses. A new pressure transducer-rotary encoder set is on the way and while they are coming, I am going to write a downloadable pdf manual with all th...

Re: Opposed-Piston Engine Project - The Steam Version

Minerva was on my side. They placed a large container for bulky trash/scrap in the garage complex my workshop is part of. Besides a couple of still working fire extinguishers, construction wood and whatnot, I've found the upper half of a weed whacker with an engine, which is perfectly fine. I wasn't...

Re: Opposed-Piston Engine Project - The Steam Version

Soooo It is slowly getting interesting again. I am now in the phase of scratching together the materials. I was thinking of buying two of those bare chainsaw engine units: https://s12.directupload.net/images/200622/temp/pi4jf5wr.jpg I am thinking of cutting off the upper part of the cylinder block a...

Inspiration for the builder: A list of other vertical boilers

Hello, I've stumbled upon an article about steam boilers for locomotives, which might not sound too fitting, but the article had a chapter about vertical steam boilers, of whose designs many look like they can work in a steam boat as well. And the design of some of them is really interesting. I trie...

Re: Monotube Boiler Design – Radical Thinking

Ah, I see. Now I understand why Lamont boilers in our dimensions seem to live a niche existence. Thanks a lot for your ever so invaluable information.

Yes, I seem to sometimes use own word creations. I hope they are clear enough to understand.

Re: Monotube Boiler Design – Radical Thinking

The cavitation issue was keeping me occupied and I gathered some thoughts: I don't think reciprocating pumps are by design unsuitable for a recirculation. I am still just not sure about the proper definition of a monotube and its destinction to Lamont/Benson boilers. If monotube boilers are defined ...

Re: Draft Indicator/Gauge

Not yet, but I was thinking of it.
I can imagine it's a great, measurable way to discover the draft getting weaker and the boiler needs cleaning.

Re: Monotube Boiler Design – Radical Thinking

I see about the suction evaporation. I didn't think of that. But how do recirculation pumps actually avoid that issue? What would the solution be? But the plumbing schematics I presented do mean that the pump does not in fact work against all the boiler pressure, as the pipe on the suction side is a...
