Dohh.. Indeed, but just trying to ensure that the incorrect use of a word (especially a noun) does not lead to it henceforth being used as the 'proper' word to describe something that it is isn't.

The original comment was to solder the twin feeder to a pair of 'split pins (cotters)'

Which I take to mean :
Go to a mechanical engineering supplier (or in my case to the right shelf in the garage) and get a packet of cotter pins/split pins

Take 2 of them.

Solder the ends of the aerial cable to the pins

Put said pins (suitable opened out) into the sockets on the radio.

They are now no longer used as cotter pins.

Next you'll be telling me that it is wrong to suggest using the shank of a twist drill bit as a former to wind an air-cored coil on, as when you're doing that it is not the shank of a twist drill, the tool is not being used to make a hole...

A cotter (pin) is a generic term for a device used to hold two parts together, for example a wheel to an axle. It can take many forms of which a split pin is just one. Other examples are the tapered pins which hold bicycle cranks to the shaft to which the chain wheel is fixed, roll pins and wedges.

To my mind the words split pin admirably describe the object which most people recognise as a split pin.

I'll grant you though that I have a tin of split pins in my workshop and the manufactur's label on it says "Cotter Pins".

Anyway anyway, correct and incorrect use of words aside, I have a small box full of the things all different sizes left over as surplus from working on classic cars so I should be okay!

A cottor pin does not need to be split. Bicycle pedals are locked to the shaft with knocked in cottor pins and then fitted with a nut for security. Look at locomotive valve gear.

Looking at e-bay I see that many split pins are made from stainless steel. You do not want these, they would be difficult or impossible to solder.

Some wander plugs use split pins with two plastic rings, screwed together to jam the wire into the loop. They are horrible. Solder the wire and if you want to be posh, cover the junction with heat shrink sleeving

Hi Vakito, more boxes of spares and other goodies will we found at the Golbourne BWVS meeting on the 9th April, just along the A580 from you.
