As an aside, I also have my doubts about the overtightening issue as an argument 'against...'
...every crank I have ever had has been a snug fit against the end of the spindle when I've removed the bolts prior to dismantling. How then is it possible to 'force them on so far' as to cause them to split (something else I have never come across for that matter...)?
Are you saying you've bottomed out the tapers on the bolts?
On every crank you've ever had
Well, that may have been more than a slight exaggeration on my part (
) but yes, over the years I have
had a couple of crank sets bottom out on the tapers...
...let's face it, we're not talking about precision-machined components here; the whole point of square taper is that it is very 'forgiving' and allowed the mass production of die-cast alloy cranks for the masses. It stands to reason there are going to be variations in tolerances/quality.
I think also you need to appreciate the vast gulf that divides the climate in which our passtime takes place; prior to the jump in shipping rates I bought a lot of stuff from the USA, mostly from California.
I put a sprung Judy on my Kilauea before giving it to my daughter and you would have thought the fork was virtually new. I have never had a fork from the States that showed anything like the corrosion we have to contend with over here.
With regard to the 'yes/no' of the OP, on the one hand we've had some rational arguments 'for' backed up by compelling anecdotal/personal (and professional) experience, whilst on the other we have the (sucks teeth...) 'Ooh, you don't want to do it like that' response with no actual, factual, reasoning why
not other than personal 'opinion...'
Also, in the context of the OP, the BB reference is
