My friend Jyh-min, now a professor in Taiwan, had an interesting method. He would take a jammed borer and turn if a few turns into a nearby tree with really "fluffy" bark. Like a big fluffy white oak. He would not even go into the wood, just into the bark. It would push the jammed part back, and the bark itself sort of crumbles so is no problem. I have not really tried this myself, but he thought it worked well....
