Yeah, Ive got a cobalt left handed drill bit arriving in a day or two, I'll be trying that before anything else. I'll have my machinist friend try to fig out a jig for me, my machining experience is practically non existant (hence my current predicament). Thnx for the advice!See if you can get a left-hand extractor-type bit in the hole. You could likely get a replacement case half for less than $600, if the cases aren't paired. Keeping the drill centered so as not to take out anything you don't want to remove is the big sticking point. A jig is a great idea if you can devise one.
