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...

Re: Idea: Espresso pump

I usually don't have the slightest problems with units and dimensions, but I don't seem to have been mentally present as I've been confusing the magnitude of the pumping power in this thread from too small to too big. Well, the delivery rate seems to check out and might be interesting for some after...

Re: How to chose gear wheels respective to torque?

Thank y'all for all the information. Well, calculating tooth geometry and material characteristics would be overkill for our applications. I guess belts are a good way for me.

Re: How to chose gear wheels respective to torque?

I think I just accidentally found a website with those kind of information. It's meadler.de which has a whole lot of different machine elements in their online shop and they actually list all important measurements of their products and even list the moment the gear wheels are capable of transmittin...
