What a wonderful walk down memory lane. Went "up" to index and seen lots
of
posts by "Teenut", Robert Bastow. May he rest in piece. I didn't see my
personal favorite "Teenut" post, the six million dollar bionic drill
sharpener, or how to hand sharpen a drill bit.
I didnt read it all-standard drill modification for drilling brass applies
in this kind of case is all.
When your hand drilling to enlarge a hole only a tad bit then your positive
rake due to the flute helix is mostly a hindrance...better method would be
to use a straight shank reamer or core drill.
