Crank Arm Removal
#1
I am having an extremely tough time attempting to remove the cranks. So far, I managed to break off the handle to the park tool crank arm extractor. Now, using the crank arm extractor without its own handle, I've managed to strip my wrench. I've used a ton of liquid wrench, a pipe that I've attached to the wrench for extra leverage and a ton of sweat, muscle and frustration. What next? Any ideas would be helpful. Thanks.

Is your crank arm aluminum? Sometimes if it's steel they can get seized onto the bottom bracket spindle. If it's an aluminum crank arm on steel, they can sometimes also get seized. If you've used the correct tool as explained in <a href="http://bikeride.com/replace-cotterless-cranks/">this video</a> and it still won't come off, I'd take it down to your local bike shop for further advice before you break any more tools.
