Speak for yourself, neither of my dads were ever much good at anything practical, certainly never had many tools to speak of (I always remembered my dad’s electric drill was 60s, it belonged to a former neighbour in Cwmbran, and he never returned it the sod). I certainly don’t remember either of them fixing a puncture let alone separating a stuck beautiful old bike bit.
I grew up taking my bike to this really old fella in New Bradwell, was about three mile from me in Stony Stratford. Rode there on me own from about age nine, he used to sort out stuff I couldn’t figure out. He was a total gent, I wish he’d been my grampa I coulda got some proper workshop stuff left to me.
Skülly-
I didn't say he helped, just he's got a fuck-off big bench vice :) That's the one I used to bang out cotters on. He was into motorbikes before having kids ruined it all and one of his favourite quips is telling my grandpa (mum's dad) that "if he had enough time to polish his spokes he wouldn't spend it polishing spokes" :D
Funny having kids now I realise jut how annoying it was for me to play around with his tools all the time.

Not quite the same thing but I had a Harden alloy nut stuck on a steel hub axle recently (in the shell and needing to come out). After brute force I tried wd40, cooling it in the freezer and popping it in a hot oven - hoping that the steel and aluminium would expand and contract at different speeds. I bought some soft vice grip jaws to try and hold the axle but they just got chewed up. In the end I tightened two steel nuts together at the same end of the axle and used brute force again, maybe all the cocking about loosened it. I did pinch the threads slightly doing that sob
I have recently seen a post where somebody removed a stuck stem by tipping the frame upside down and pouring evaporust down the headtube and letting it soak overnight.
Looks like there are flats on your pedal axle though. Can you get those in a big bench vice? [I know easier said than done sometimes - I have to go to my dad's. Good old dads and their fuck-off big bench vices. He inherited it from his dad so maybe one day it will be mine :)] Then make a bigger lever of your crank with a pipe or something and apply brute force?
