Hi. I need some suggestions on getting a steel pedal spindle out of an aluminium crank. Looks like it was put it with no copper slip and is now to all intents seized.
I have tried the following; soaking in WD40 for a couple of days, soaking in ammonia for a couple of days; not at the same time , heating the end of the crank with an electric paint stripper.
Apart from drilling the pedal spindle out does anyone have any other ideas?
Prefer not to chuck it away as it's the chainwheel spider crank.
