The special feature of the Deutschlandticket isn’t really its price but that it is valid not just on trains but on all the things.

Good morning! I overslept and immediately paid for it by the breakfast room being a mess.
Always arrive three minutes after the breakfast room opens. The you will only have to share it with two German couples who aren’t on vacation for fun and who are too tired still to make any kind of noise.
Anyway, the tram is coming back to the surface in Essen but it isn’t quite there yet. So I’ll do a quick walk down the wonderfully quiet main pedestrian street to Rathaus station.

At Rathaus station (which is under a big shopping mall), the electronic destination boards are broken and there is zero alternative information on the platform. The destinations given on the wayfinding upstairs don’t match those given in the app.
Luckily I don’t have to deal with this as it turns out that the tram line into Mühlheim is being bustituted today, so I am now walking back to central station to get the U-bahn line instead.

Oh great: for the first half, that U18 runs in the median of the local urban motorway. I guess this is fun during rush hour when the motorway is completely clogged and you just zip past.

I noticed this already yesterday: The platform displays here in Essen often keep saying that the next train is coming “now” (“sofort”) for quite a while after the train has left which strikes me as … not ideal.

Mühlheim Hbf. You can’t complain about the wayfinding because there isn’t any. Plus, the platform displays, which show the next departures just fine, flip to “Check train display” when a train approaches. I only concluded that I am on the right platform and this is indeed the 901 to Duisburg because it says it belongs to Duisburger Verkehrsgesellschaft on the side of the train.

In Mühlheim, the metre gauge tram network of the eastern Ruhr area meets the standard gauge network of the western part, which leads to rather complicated arrangements.

Building a Hydraulic Gear Pump Isn’t So Easy
The gear pump prototype in action. (Credit: Artisan Makes, YouTube)
Hydraulic gear pumps are deceptively simple: just two gears rotating together, forcing the hydraulic oil from one side to the other where the teeth don’t meet, and thus providing the ability to pressurize said oil to make hydraulic cylinders, final drives, etc. do their thing. As with most machining projects like this, the devil is absolutely in the details, particularly in the tolerances. This is the crash course that the [Artisan Makes] channel on YouTube is currently going through.In this part one of a series on a DIY gear pump, scrap aluminium is used for the housing, along with 1045 medium carbon steel for the gears and W1A high carbon steel for bearings and other wear surfaces. Since at least one of the gears needs to be driven, a lip seal rated for 10 bar is used to provide a path for the shaft. As noted in the video, this is supposed to be a learning experience, ergo it’s a simplified design that merely targets being functional as a gear pump.
With the basic design figured out, the parts were created on the lathe and mill, followed by assembly. Most of the controversy is about the tolerances within the housing, as any leakage will reduce the efficiency. This means the spacing between the gears and housing, space between the gears and bearings, as well as that provided by the gasket that seals the housing base and top. This is where the comment section somewhat explodes with criticism and advice.
As can be seen in the demonstration with a better gasket, there is absolutely flow when driven at 1200 RPM, but also clearly severe leakage as evidenced by said flow not moving quite as fast as it should. We’re looking forward to the next part, in which addressing these tolerances is tackled, with hopefully a much more performant gear pump resulting.

Che poi, spacciano per Made in Italy ciò che non lo è, ma il vero Made in Italy costa. Gli italiani, in massa, hanno perso la capacità di capire la qualità, quindi vanno di schifezze a prezzi bassissimi. Il Casentino ti dura una vita ma costa. Quando avranno capito che il low cost non esiste perché qualcuno il prezzo lo paga, la filiera italiana sarà morta e sepolta. Amen.
