During a windstorm my WS-2300 anemometer lost one wind cup.
As the WS-2300 meteostation is a very old model, spare parts are almost unavailable. I decided to fix the anemometer on my own.
I made new wid cups from a copper sheet using wooden mold and iron ball
Wind cups soldered on the arms are held by carrier wheel with a tenon. The tenon fits to the original part with axle. This ensured succesfull instalation of the repaired wind cups.
