thanks guys. i stopped by sears and got a bolt extraction kit. has a bunch of sizes. you just drill the middle of the screw out and then put this other tapered bit with reverse threads in it and it came out pretty easy. if the screw was any smaller i dont think it would have worked. i did read about using a dremel with a cut off wheel to just cut a slit in the broken shaft that you could then use a flat head screw driver you just turn it out which i thought was a pretty good idea. it didnt require me buying cool new tools tho so i kept it on reserve!
