It isn’t pretty and I have a lot of filing to do. I chain drilled enough that I could line up my dremel tool and finish up the hole. Amazing how hot the metal gets with a grinding wheel.
(Edit) forgot to add the blasted photo!
@va3db this is THE WORST part of any project. A jeweler's saw can be useful, if you haven't tried it yet. One day I'll have a small milling machine for this.
