I drilled and redrilled & redrilled & redrilled with larger bits once
until I was able to 'peel' the remaining bolt from the threads.
Almost as scary as cutting away the bearing material with a dremel
tool to remove the last of the pilot bearing from the crankshaft. Got
that one thin enough to peel out too. Uncomfortable feeling.
