Cracked the Crankbolt Inside the crank.
you can try drilling a slightly larger hole (dont eat the threads in the crank out) but straight this time then get an easy out in there to get it out. Otherwise your gonna need to take it to a machine shop to get it extracted. As far as I know there are no other ways to get it out..this is a bad place to start making mistakes like crooked holes unfortunately.
if you already have a hole (what size?)
there is a tool called "bolt extractor" (DUHHHH)
is like a reverse twist conical drill bit, square end like a thead tap.
to use like a theader, instead you twist it backwards (to the left) hence the bolt will come out.
try to buy a 3/8 extractor and see which is the CORRECT DRILL SIZE for that extractor and buy a couple of cobalt drills ( THE BOLT IS VERY HARD), be very carefull and deliberate with each "push" of the drill
DO NOT! DO NOT! break a cobalt drill bit inside the hole!!!!!!!!!!!!!!!
then try to "tap" the extractor backwards (i mean to the left) , the conicity wil lodge itself inside the bolt and then will begin to drag the bolt towards out!
thats why the hole "can" be offcenter, crooked, BUT VERY ROUND!!!!
GOOD LUCK!
