I'll trade you my wife and kids for your broken grinder! Believe me, I'd be money ahead on that!!!
I had a crazy thought about submerging the armature in a bucket of water and leave the shaft sticking out far enough to braze up the ruined gears. After building it up with brass sufficiently, and once cooled, chuck it up in the lathe and turn down the built up area. Once turned down to size, you could use a file, a die grinder with rasp cutter or even the mill and a small end mill and rotary table and try to re-shape the teeth. Then maybe a soaking in WD-40 to ensure all the moisture is gone and maybe it will work. OR, center drill a pilot hole past the good area, cut off the bad portion and then cut off the good area and make a spacer to place the good portion where the bad teeth were. Then solder this piece in place using the submerged armature trick.
