FG-230 bridge plate repair

It's normal for them to be chipped.  They drilled the hole without backing them up, blowing out the back.  I make a bridge plate patch from 1/16" maple and epoxy it on top of the old one, then drill & taper ream to clean up the holes.  Use a few layers of aluminum foil pressed around the bridge plate to get the shape, measure it and make a cardboard template, trim the template to the shape of the existing plate (by feel), and transfer the shape from the template to the maple.
