Turns out they have 49(?!?) teeth instead of the 50 that I needed, the smaller part had the correct number at 10. The gears are modulo 0.4 and that's not common. 
Trawled the net and the only ones I could find were from a Spanish company, 98p each but a whopping £15 p&p and you needed to be a company and register with them.
Using my hobby drill, a selection of burrs etc and some araldite married the 50 tooth part of the old cog with the 10 tooth part of the washing machine ones. I managed to work out how to put the whole complicated mechanical thing back together. And it ran! But only for a few hours: there's another cog with a dodgy tooth that actually drives the minute drum advance cam and it stopped there.  Now it's hunt the cog to make a hybrid up for that.
Probably a good thing I didn't spend the £20 odd quid, then I would have been mad. Not that the oven needs the clock and we've never used the timed switch on function but I thought it would be nice to fix it. |
Isn't that something which could be 3D printed? Just a thought.
