Why is it, that some people tighten stuff to within an inch of their life, so the next time you go to remove what ever has been tightened its a bitch!!?

just replacing the bottom bracket on my pedaller an have so far snapped an impact socket (sealey) an bent a long allen key socket thingy

It's not a left-hand thread is it?

BBs are famous for seizing. Fine pitch thread tightened to nearly 70Nm in some cases.

I presume you're trying to undo the crank bolt rather than the BB itself though if you're using an allen key? Even some conventional crank bolts need doing up to 50Nm

I had to stand on a six foot piece of scaffolding tube over a breaker bar with the tool bolted in to remove the factory-fitted BB from my bosses bike.

Remember the left side of the BB is reverse threaded. (the crank bolt is not).

Heat is your friend.

I know the feeling. I decided to refurb my really old hard-tail a couple of years ago. After about 12 years of careful and diligent neglect the bottom bracket was stuck solid. Wound up taking a blow torch, about 5ft of scaffolding leverage and 3 burly blokes from the ye olde bike shoppe to get it shifted. Was rusted completely solid - worst the shop had seen with barely enough thread left to fit a new BB Laughing

Shit of it being the bike was nicked about 6 months later. Wish I'd left it looking like a wreck.

Because thick fuckwits such as myself get paranoid it will come undone (admittedly through ignorance) and so tighten with almost all the strength we have.

I only just learned you can over-tighten an Axle nut to the point of crushing bearings... fail!
