I had some time this afternoon and was adamant that the stuck crankset was not going to beat me.
After some thought I had a rummage around my tool box, found this (a tap wrench) and decided it should be able to shift it, so I clamped it in the vice.

Gave the spindle a couple of clouts with a large hammer and off it popped!
The adjustable cup was seized solid, but I put some penetrating oil in and left it for a bit, the trusty tap wrench came to rescue again, and off it came.

Luckily I had a spare BB so I cleaned the threads, copper slipped them, greased the cups and put it all back together
