Another great way for pulling steel studs out of Aluminum quick and easy is to TIG weld a bolt to the remaining portion and then twist it out. You get heat + you get a new head which are both really helpful at the same time. The only problem is you need to have a TIG welder AND be able to weld in funky positions which unless you have a finger amptroller is hilarious, knees, other people etc.. Yeah sucks but definitely not the worst I think. You're surrounded by lot's of folks with lot's of worse in vanagonland so the competition is pretty stiff ha. Do you have a drill that is low clearance enough for it as per Frank's suggestion?
