Quoted message said:I sprayed some penetrating oil on the chainring bolts. I loosened the
four outward facing ones ok; they were VERY tight. When I tried
loosening the inward facing chainring bolt (part FC-RE102), the
non-standard one that screws the chainring to the crankarm, it
stripped. [censored], if it was a normal chainring bolt I could just drill
it out, but this one screws into the crankarm. Anyway tring to salvage
a bad situation, I carefully drilled this bolt but am left with a
small piece in the crankarm. I replaced this chainring bolt with a
normal one, but have lost the benefit of having the chainrings secured
to the crankarm - anything else I can do here ?

That bolt, like most new chainring bolts, arrives dry and
tight. Except this one is aluminum. It might have been
better to prep it, and the other four, with grease when the
crank was first put in service, rather that wait for the
inevitable oxidation to make it more difficult.
Then again, it might have been overtorqued dry when
received. (IOW, it may not be your fault but you can't know
that)
