Help removing cranksRubberbandman

I'm having a problem removing my Ultegra cranks. The threads inside the crank for the one key release bolt are stripped. Any ideas how to remove the crank? Is it possible to bang it off?

Thanks for your help,
dd

... in some cases, once unbolted but with no extractor tool or mechanism available, you can try just riding the bike around for a while and they may just work loose.
It's really quite simpleKerry Irons

You remove the self-extracting thingy, and then you remove the cranks with a standard crank puller. This may be impossible depending on what you mean by "The threads inside the crank for the one key release bolt are stripped." Not a very clear description but if it means that the thread-in self extractor has stripped the crank itself, then the next best thing is a gear puller. Stop by any decent machine shop and they will probably pull it off for free, just for the novelty. Riding with the bolts removed will likely result in the crank coming loose, but also may risk damage.
