So, at this point I'd be tempted to get a carbide tipped tool of some kind that would make a mark.

dremmel tool? The metal on the bobbin area is very hard metal. I did it so many times now that it isn't all that hard. I've not done the bobbin end on a zz machine though - just from the needle bar. Same problem with marking though - oil and very hard metal.
I have a couple Elna's that are going to need that kind of work at Ray's class.
