For a while the Kenwood Chef (blue and white 1960s or early '70s vintage) has occasionally--wilfully--shat its chunky nut from the plate into which the beater screws into the cake mix. I've washed the offending article and refrained from jokes about added ingredients.
A handful of cakes ago, the KC stopped. M turned it upside down, discovered where the power cable had worn through over the years, and fixed it. The upside to this (apart from having a working KC again) was enough crud had been dislodged, air had got to its innards, that it smelt less of burning lubricant whilst working.
Today, the whole mechanism was slipping so it jammed against the bowl (this is the white pyrex variety not one of the more recent inferior stainless steel or plastic ones). I'm terrified of the bowl breaking (or breaking further: it has a chip on the upper edge of its lip, sealed with pink nail varnish, where I try not to aim when cracking eggs.) We repeatedly dismantled the clockwork mechanism, cleaned it up, reseated it, screwed it up. By the time I'd hand creamed the butter and sugar and beaten in the eggs it was fettled enough to mix in the flour for Looby Loo's lemon drizzle cake. Then it fell apart again.
I do not want to have to replace it. I learned to bake with a similar (possibly slightly newer) model and never really got used to its blocky brown and orange replacement (which my Dad had to replace last year, so it also did rather well). Looby Loo learned to bake with our model, which M inherited from his grandmother. We like our well-worn sturdy technology. (I own one sewing machine from the 1950s that was my grandmothers and still refer to the second machine--from 1977--as the new one. The old Singer is superior.)
(And I promised birthday cake to take into school on Monday, too.)
