Im Grunde wollen sie erneuerbare Energien, Solar und Windkraft sind ihnen aber nicht verschwurbelt genug. Vielleicht muss man ihnen zu den Solarzellen noch ein paar Orgondefäkatoren oder so verkaufen, dann machen die auch die Energiewende mit.

Von deren Webseite:

Schülerprojekte/ Schulgarten/ Werken, angestrebt sind honorierte Projekte für Schüler dieser Stadt zu den Themen freier Energie (unabhängige Energiegewinnung durch beispielsweise Schwerkraftantriebe, Magnetantriebe, Sonnenenergie ohne Hitzeentwicklung oder ähnlichem, Kinder sehen die Welt noch mit anderen Augen

Ist wohl die c/600euro Fraktion der Afd.

Thanks! Not my design, though. It's a German made Sorotec Compact Line 0805. I don't think the brand is well known in the US, but has a good rep here in Germany. It came as a kit (just the mechanical part) and I had to plan the control cabinets for machine control (eding cnc 720 + JMC closed loop steppers with integrated drives) and spindle control/vfd (omron mx2) myself.

The cooling is being done by an aquarium pump and a 5L bottle of distilled water at the moment. For the winter I'll have to make myself something with a heater, because the spindle doesn't like temps too far below 20°C and heating up the coolant with the spindle would damage the bearings.

Auch hier bei uns liegt einiges im argen. Wer von uns hat genug Wasser Zuhause bevorratet um ein paar Tage ohne zentrale Versorgung überleben zu können? Ich schätze mal die allerwenigsten.

Wasser bevorraten erscheint mir unsinnig. Die Werke haben 24h Notstrom. Lieber genügend leere Kanister und Micropur-Tabletten bevorraten, damit man in diesen 24h genügend Wasser abfüllen kann.

No one but complete morons are asking to specifically make a product by emitting carbon dioxide. No company is emitting co2 for "the global citizens". They make products to earn money. Emissions are an avoidable by-product no one asked for.

You mean from the end here as circled?

Yes, exactly!

On of the thing I was actually also considering was making small tabs that I could use to keep it from sliding side to side and still replaceable. Think that would be wise or just glue the bastard down?

Just use a tiny drop of superglue to hold it in place. It can still be carefully broken out and be replaced this way. The rest is done by string tension.

I used a 3D printed nut for the rebec I posted in this community. PLA works best because of it's high stiffness, even better if it's PLA-CF. Make sure to add enough perimeters to not get hollow spaces in the nut.

If you manage to print it standing on its side (add a brim!), then the layer lines will follow string direction and the strings will glide better on the nut.
