Most of my repairs seem to be mechanically based. We have a hand mixer food processor combo thing which was not expensive (for Switzerland). It was given something a bit hard to chew and the plastic coupling between the motor and the chopper melted.
I turned a replacement from Delrin, milled the cross and good as new.
A few years later the hand blender bit started screeching so down to the workshop. Dismantling took little time as the cutting blade was swaged onto the shaft. What was inside was not pleasant considering it was for use with food. There was a thin, broken, plastic seal, a cast iron bearing and some sort of spacer that had disintegrated plus a load of clag.
I looked through the parts that I use for my model engine making and found a suitable 6mm sintered bush and a lip seal as well a couple of O rings. A new bearing body was turned from aluminium and the system reassembled. Re-swaging the blade was a little tricky but worked.
Did this make economic sense? No. Did it keep E waste out of the waste stream? Yes. Did I enjoy the challenge? Yes.
