Got a square taper NDS crank stuck. Really doesn't want to shift.
Have you stripped the extractor threads yet? If not, you're not trying hard enough :-)
I've yet to see a crank which can resist my gear puller/bearing splitter, this pattern is best for cranks but the ones with two or three fingers have been used successfully by other people, although they tend to mark the back of the crank more.
Assemble with the jaws behind the crank and the centre screw pushing the BB spindle, keep tightening the screw until the crank separates from the spindle.
