Damnit!!! Here's a good one for you. It's frozen right, so I spray it good with some penetrating breaker. Then try different allen wrenches (3/32" seems right), they're stripping. I get out one of my allen wrench socket thingies, yeah, it breaks off in there. Brittle enough to break, too hard to drill out. After wasting time on that for a while and playing around, nothing else occurs to me.

So I carefully drill and then cut the sheetmetal, instead of one hole to get to it there is now a nice little 1/4" slot, I can correct later or leave, no hurt. Only thing that has occurred to me at this piont is to weld something to it to give me something to grab and turn. tried a bolt, tried a screwdriver, another bolt. F*(# the weld always gave out before the thing would turn!!!

I don't know what else to do at this point. sprayed a butt load of penetrator and am leaving it for now. any ideas I'm open? (normally it would have been easy to just drill and use a remover, but with that hardened piece in there I'm screwed at that angle).
