stripped crank puller threads

when the puller threads are stripped on a crank i usually use a pickle fork. the one sized for tie rods is the right size. i also have a set of jacobs chuck wedges. size number 2 has a 9/16 slot that fits. the wedges don't really damage the crank. the pickle fork is faster and does some damage
