Thanks to all for the suggestions. "Properly sharpened" drill bit in
1/16" size means how it comes from the supplier, at least for me. I
have not been successful sharpening one that small.
I like the jig for going through the flats on the bolt head, and may get
one, but that doesn't solve the issue for nuts. A diagonal hole through
two adjacent flats is what I've seen on aircraft, and what I once had on
my 1966 Saab on the oil injection pump (2-stroke engine). Obviously the
aircraft influence.
I'll try again with sharp drills, cutting lubricant, clamped jig, and
making the starter hole and see how it all goes.
Thanks.
