At school, metalwork was one of the subjects taught alongside technical drawing. We had 3 Colchester bantams and a Boxford AUD alongside all the other metal working kit. Most of it was sponsored by a local engineering firm that made machine tools, taps & dies etc. Not sure if schoolkids these days would be let loose with such dangerous tools. Oil fires were a regular occurrence when the whole class, towards the end of the lesson, was dropping red hot metal into a pot of oil to blue the metal.

Yep, times have changed. Things that were totally normal/of no concern at all hazard-wise to us back then are now "shockingly dangerous!"
re the replacement horn - is it louder than a (properly working) oem horn? My original horn works fine but on the road I think the only person that would hear it is me.

It has the same specs 12V 3A 105db so is reasonably loud but it is never going to compete with modern cars that have two installed. There are others that are louder but draw 5A. Without knowing the switch rating, I wouldn't go any more than the OEM version without fitting a relay.
I just wanted something that works reliably and doesn't look too out of place.

Sprayed the front cone with a bit of wheel silver paint that I had laying around.
Not original but a functional necessity.
It fits. Bit of a tight fit getting the cover back on, had to lube it up with some silicone grease and warm up the cover with the heat gun. A good firm press and it popped in.

Great thread, I never realised how interesting a horn replacement thread could be, more than good luck that the plastic cover fitted.
PS I'm not being sarcastic either.
