I thought I'd wing it and sent that onto several friends but got FA response. Perhaps we set the bar too high with this post, and are now paying the penalty.
If they were Scottish crows it would be a murrrrder...
Hate to be pedantic on this site, but there are Ravens !
There is a serious point there. Taper fittings which rely only on friction are extensively used for holding machine tooling. First time I came across it was on a big electric kango drill we were using to drill quite deep 1" diameter holes in rock, the drill bit was just held in by a tapered socket with nothing like a chuck or anything

The same is true with lathes - you have drive centres and tailstock 'live' centres which are just held by tapers. They need knocking out from the back to get them out (actually on my tailstock it auto-ejects when you wind it in far enough).
