The dummy being me. I've dealt with the joys of cottered cranks (on my raleigh of course) but this square tapered crank business is new to me, after much work with a cheater bar and a vice I got the locking nuts off the crank arm and now the crank arms seem to be frozen on the spindle itself... being as this is a sugino super maxy crankset and I'd like to use it on this bike after the rebuild, any non destructive ideas would be great, alternating PB blaster and rubber mallet atm.
