Grinding chainplate bolts

["Warren Stevens" <warren@xxxxxxxxxxxx>]

I saw a couple of boats at the July regatta where the chainplate
bolts had been ground down, so the pin would fit through the
gudgeon plate.

What is the best way to do this?  Some kind of dremel
attachment?  I need to grind mine down, so far I don't have a
good idea how to do it.

Thanks

Warren
