Thanks, yes the capstan animation is one of my favorites :). Great point on steel not being an option, I should have mentioned that. RE: Hartford Steam Boiler Inspection - cool, thanks for the details!

RE: Things are more complicated - I totally agree. My favorite part of the article is probably the belt transmission section. I wasn't sure how it was possible for a leather belt to transmit so much power. Super fun to just dig in deep

Thanks! And https://modelengineeringwebsite.com/Classic_ME_beam_engine.h... is almost exactly the CAD model behind this beam engine. Designing that on paper would have been quite a challenge.

You are welcome! I agree, it's a really nice way to learn about something. Digging into the transfer of power with belts may have been one of my favorite parts here, even though it's not really steam directly :).

Yes, great details! Not sure if you've read it, but "Richard L. Hills, Power from Steam: A History of the Stationary Steam Engine (1989)." is a truly wonderful overview, that really digs deep into the business. It has many le

Thanks for the pointers! That is an area I've not explored much - reciprocating steam using modern technology. Using modern electronics, sensors and valves to optimize steam expansion would be a fun project. Perfect cutoff every time :

Thank you, a lot of research went into it :). And 100% inspired by Bartosz's articles - he is the first line in the credits section.

It was a mix of techniques, this article has been in progress for quite a while :). The first part was modeling all the relationships for an accurate beam engine in onshape (great cad tool). Then, I built a custom exporter to cleanly expor

Thank you! I have a few ideas for the next article. Locomotives are up there on the list, but they are the final challenge of steam engineering, there is so much to cover. Also considering the origins of precision - the intertwined evolutio

Oh my. Yes, you are totally right. This was tricky because I needed to merge two different animations (the governor moves independently from the rotation of the wheel), and I seem to have messed that up. Fix shall be deployed shortly!

Blondihacks is amazing. Beware though, you may be buying a lathe and a milling machine soon after you start watching :). It's a great hobby. Manual machining is totally different from writing code, but you get into a similar state of f

Definitely a fun note :). I think I heard it first from a Jay Leno youtube video where he was showing his amazing collection of steam powered machinery. This is from the article, but governors also played a role in kicking off modern contro

Thanks! RE: units - Good catch - there is almost certainly a better way to phrase this one. I always tried to give physical examples to make things more concrete. But who knows, maybe the bathtub will take off as a unit :).

Awesome! It's pretty amazing all the concepts that need to come together for even these very old engines. I found I built a better understanding of what was going on as I built out the animations as well.

100% - his articles were a major inspiration, and first line in the credits: - Thanks to Bartosz Ciechanowski, whose exceptionally well written and designed articles inspired this one. Glad you enjoyed the units :).

Thanks! Yes, some of the animations were created from this onshape model, which I rigged for motion: https://cad.onshape.com/documents/ebc9190f428cf30153c06148/w... . For other animations I put together a style gui

Author here. The beam engine created power from steam, and was a key part of the early Industrial Revolution. The article is a deep dive into the engine: how it works, the history behind it, and the engineering tradeoffs the builders faced.
