Back in the day I used to be a crank-grinder and straightener...

If you store the cranks sideways, 'on a rack' then its a real bummer getting to the bottom ones... shruggy

But I remember my engineering master at school telling me the 'five-ninths' rule! argue

If you have a metal bar of say NINE feet long, then the two supporting places should be TWO feet in from each end leaving FIVE ninth's in the centre...

So if you are laying a crank on its side the supports should not be the large outer counter balancers, but the next ones in... iagree

Carpe diem, quam minimum credula postero, thanx Horace!

There’s no point trying to fix stuff that ain’t broke,,, 'but if ain’t broke',,, you is not trying hard enough...
