Coterpins were the bane of my young days on my raleigh grifter ... used to always end up with knackered coterpins .... I used to put it down to my strength but more likely to my lack of bike maintenance skills 😉
.... although I used to keep them tightened regularly - never really got my head around the problem.
My problem was the opposite - trying to get the £%^@!*$ things out. I could ride for weeks on a cottern pin with no nut and it didn't budge a bit.
Possibly due to installing them firmly with a large blunt instrument..

As a matter of interest, where in the world are you? Cranks using cotter pins are now vanishingly rare in the UK.
"Vanishingly rare" is a bit of an exaggeration - there are plenty of them still around. Oh, and be a bit careful buying cotter pins because there are two sizes and they're only a tiny bit different in diameter (6mm and 6.5mm if memory serves).

You're not supposed to use your head. You are supposed to use a ring spanner, a block of hardish wood and a hammer.

OK, put it differently. I can't remember when I last saw such a bike in use. Twenty years ago? There were a couple in the junk room at the back of my LBS, but the people from Scrapheap Challenge came in and bought them last week. You thought those were real scrapheaps on the programme? So did I, but apparently it is not so.

It's not personal. They were the bane of everyones' youth...
We used to build bikes from bits found on tips when I were a lad in the mid-50s - cotter pins always seemed to need to be filed before they'd fit properly.... -- Regards Alex The email address above is a spamtrap. alex@ the same domain will reach me

ITYF they're 9.0 and 9.525mm (3/8 inch). My '64 Moulton takes the latter.

Last year at the FEIHPV meet. Rachel has cotter pins on her bike (IIRC - IMBW).
I have another four bikes in the garage with cottered cranks (For definite).

It is, but is suitably augmented for both visual effect and to ensure there are enough old bits around to complete the challenge. They do use real scrapyards for the scrappy racers bit.
If they were to do an HPV version, how about a URC team? There are enough hackers and bodgers around to put up a reasonable effort.

They did one a few years ago wherein the competitors had to build a stored energy racing vehicle. The Appointed Experts were inveterate recumbent homebuilder Clive Sleath and Mr BHPC Comp. Sec. gNick Green, who says that Robert Llewellin gets comically drunk on about half a pint of BEER...

This morning. Apart from that one (mine), Friday, shopping in town, there are lots of old bikes around in use.
I'd agree with "increasingly rare" though. Mine's the only one in the car park at work today (though not the only one I've ever seen there).

Saw a few yesterday (not counting the ones I and my friend were riding).

No, not as such. It always seemed remarkable that the heap always contained just the things they needed. I assumed they got in a large quantity of stuff from a real scrapheap and then 'seeded' it with a few choice items that they thought would come in handy for the particular challenge.

Ah yes, that sounds more like it. If I'd thought about what those sizes were in inches I'd probably have realised I'd got it wrong.

I've a bike where the chain ring crank is part of the BB axle and the opposite crank is held on with a cotter pin.

Looking at some of the efforts produced by people here I think a URC team could be hard to beat. -- the.Mark

last time I watched it (which was a long time ago) the cars were all LHD and had dollars wrote in the windscreens. Perhumps they were not allowed to do anything so dangerous over here (or couldn't guarantee the weather)
