[Closed] That's one stuck bottom bracket.

Turning it the right way? 😉

I seized one on for good by forgetting the thread direction. I knew it, I just waded in that day without thinking. 😳

Nah - definitely the right way!

That is one cheap/weak/underspecced vice more like!

Unless you have massive hands then that was a puny vice.

Presuming an internal bb? The last one I did (which my LBS gave up on) I did without a vice. I heated up the bb with a gas canister type blow torch focussing the flame at the spindle from both sides. The only reason for aiming at the spindle was to minimise paint damage.

Then after a few mins of heating/c ooling/heating/cooling I fixed the bb tool in place with a big washer and a bolt and put the frame on the floor up against a wall. Then with my 6ft aluminium lever pole slipped over the adjustable spanner I got it moving. Some eeiry sounds echoed around the garden but it came loose, I was also in a contortion keeping one foot on the frame and one arm on the pole! Lots of white powder evidence of corrosion came out too.

Sorry but that's a small vice looks like a swivel base so a step up from a jewellers vice got a bigger one in the back of my van 🙂

lidl?

No one think about using some copper grease on the threads to start with, then? 😀
