Stuck pedal
I recently scored an '86 Miyata 310 that some genius was trying to turn into...I dunno what.
Among other things on it are some crappy and mismatched MTB pedals, one of which I can't bust loose at all. Worse, the spindle is soft...wrenches, vise grips, and other pliers are just rounding it off, can't get a grip on it at all. It's the left pedal, and yes, I'm turning it the right (left) way. I've tried penetrating oil, a heat gun, etc...all the normal stuff, and I'm making no headway at all.
It's occurred to me to try and drill it out, but I don't want to bugger up the crank arm, since it's an original Miyata part and not easily replaced. Any advice would be appreciated.
