The words "False economy" spring to mind.

False economy indeed - but see my posts above regarding Dutch labour rates - it might work out to be cheaper to buy a new crank! I'm still investigating this option.
I have no intention of chucking it all back together (and I don't think that has been suggested: measure measure and measure seems to be the message) - that would be like being scared to jack up your car because you think it is too rusty - I'm definitely of the opinion that you do some something right the first time - and then hopefully you won't need to do it again. If you, however, do need to do it again at least you won't be kicking yourself because you know you did a pants job in the first place...
