Private Person braucht eine Kleinarbeit in Auftrag zu geben, heißt es handelt sich um Kleinstmenge. In dem konkreten Fall hier drei zugelieferten Stangen aus Metall einer Stärke bis 3,5 cm bearbeiten.

Auf welcher Online-Plattform der Ausschreibungen eine Chance willige Firma in Deutschland zu finden?
Vielleicht privaten CNC-Enthusiasten mit eigener Maschine.

Pro Stange:
* Drei geradlinige Nuts quer gesamte Stärke der Stange, jede Nut bis zu 3 cm lang
* Stange an zwei Ecken in der Stärke der Stange kleiner machen. Gesamtfläche der Abtragung pro Stange bis zu 6 qcm.

Edit:
Bezüglich der genannten Nuts, mir fällt folgendes auf, keine Ahnung ob ich es immer eine Nut nennen darf. Es ist wie: Zunächst eine Bohrung machen, dann Bohrwerkzeug weiter drehen lassen und in Z-Achse nicht heben aber senkrecht zur Längstkante der Stange es hin zur deren Längstkante führen solange bis keine Materialabtragung mehr stattfindet.

Den Bedienungsanleitungen von Heizkörperthermostaten entnehme ich öfters eine Empfehlung, in Sommerzeit die Heizkörperventile voll aufzumachen. In vergangenen Jahren immer vergessen drauf aufzupassen. Diesen Sommer doch nachgegangen - wenige Wochen her alle Thermostate auf AUF gestellt; alles tutti... bis letzten Samstag Abend - da geht plötzlich die Heizung in allen HK an (Mehrfamilienhaus mit Zentralheizung, Heizwärme wird im Kellergeschoss aus Fernwärme erzeugt, dann an die Wohnungen verteilt). Kurze und eher flache Recherche ergibt, es sei der Sachstand in Deutschland, dass die Heizung in Wohnungen nicht abgestellt ist.

Hier aber der Konflikt, wird man den Empfehlungen der Hersteller von Heizkörperventilen/-Thermostaten nachgehen, so entstehen die ungewollten Kosten. Sollen Juni oder Januar (zum Beispiel) die Tage der Hitze vorbei sein, so sind die Temperaturen in Räumen noch weit davon entfernt, dass wir dort frieren. Insofern wollen wir im Sommer keine Heizkosten tragen. Warmwasser ist in meiner Äusserung nicht inbegriffen.

In Empfehlung der Hersteller: es soll der Schonung der Ventile/Thermostate dienen.

Was meint Ihr dazu?

How well do wood/chipboard-style screws work in aluminum? Specifically: drilling the hole, achieving a secure hold, and—if necessary—unscrewing and re-screwing the fastener while maintaining a fit comparable to the original installation.

Application: mounting an aluminum bar or flat bar (2–3 mm thick) onto a stainless steel sheet. An electronic device will be attached to the bar; the device's weight is comparable to, or at most equal to, the weight of the bar itself.

I considered bonding as an alternative. However, the adhesive would need to be thermally conductive, and bond degradation over time would be a concern.

Another alternative is riveting a U-profile, though that presents different challenges for this specific application.

Looking for strip suiting my current project goals. Cause it is my first LED project and currently in very early phase of my planning I use this week only rough figures.

Looks like I will need to purchase 5 meters strip. Lot of details still to be determined. Power range of operational strip (after cut) estimated by myself to not higher than 20W. All purchases will be conducted in EU. All the offers of 5 meters strip I found so far and classify as candidates specify strip power rating in Watts. This is the point at which following question arises on my side:

Are these 5 meter strip power specifications literally for complete strip before any cut, or per 1 Meter of strip? Will I need to talk with seller every time to know it exactly?

I proceed by following plan in my project:
* know the details of strip target usage
* know the requirements the future user of the lighting raises
* know what is already given and is going be reused
* find matching strip
* find driver matching the strip and its used distance and number of strips in parallel circuit
* remaining steps

Used among others in engine bay, bmw cars the F30 series 2011 to 2018 with combustion engine B48, B58, B38 or diesel same design. Electric connections.

Do the common experiences regarding cracks in oil filter housing include coolant discoloration toward black?
F30 330i started in its age about 5 to present slow coolant leak. New coolant reservoir cap slowed it down. The cause of leak was never found.
However newest development is the exceed of coolant level above max marker in turbo charger reservoir. Additionally coolant in both reservoirs shows discoloration toward black - low temperature circuit stronger. Does a potential damage of head gasket need be taken in consideration?
Actually turbo charger cooling system does not flow cross head gasket, doesn't it? Question arises because coolant in low temp circuit is also black.

Cap of big reservoir is again hardly to unscrew like the months prior to cap renewal.

Has anyone else noticed that the central latch doesn't actually latch onto anything? When rotated to the "Locked" position, it simply points into the engine bay—where, however, there is nothing but empty space. This rotating tab cannot possibly provide a seal.
Observed on an F31 (Model Year 2016) purchased on European market.

Does the pattern described below matches common experiences regarding symptoms of coolant losses?  

BMW with B48 252 PS (built somewhen between late 2015 and early 2018) loses slowly coolant. So far no leakage spot found. Current diagnosis measure is the use of liquid detector die Brilliant Coolant available on european online retailers. A number of short-distance drives were accomplished with detector die put to cooling circuit. I can inspect engine bay using only infrared lamp (no special glasses available). So far got informed about BMW common weakness regarding coolant robber houses and observed micro-perforations of the hose connecting coolant reservoir with engine head. Following those hints I inspected that area using IR lamp and see spurious traces in area that I judge to be engine suspension below one such hose. Residuals look like pollen particles distributed slightly on upper surface of engine suspension more than continues tracks of dried fluid.

It is hard to document with camera what I see during inspecting the depths of engine bay.

The imprint on reflector inside this lamp sounds max. 100W. This lamp was produced in time when the world was still unaware of LED technology . Going to replace bulb with LED-based one, socket E27 power 12W, or 100W equivalent old-fashion bulbs. 1521lm brand Osram, ~230V. Will this LED bulb produce less heat than 100W old-fashion bulb?

Slides were created manually. They comprise only text. Each slide is a series of bullets while every bullet one rather short sentence. Zero backgrounds, template merely splits slide in two columns of text. Author decides how the columns get each filled with text. All the layout details presented so far need to be preserved.
The job for AI is to analyze the subject of each slide and generate up to three illustrations echoing subject 3 major points. Illustrations in form of stickers, symbols, icons, simple pictures symbolizing the subject of slides. To be delivered as PNG or SVG files. Illustrations to use only colors black, white, up to 3 grades of gray. Shapes in illustrations not overloaded with graphical details.

Slides topic is IT, computer networks, security, trainings.
So far chatGPT failed on this task. I however missed to prompt so far for instance that illustrations will complement presentation slides, must be understandable for human audience and illustrations work as they usually work on presentation slides.

What else to consider to succeed?
