I am guessing that Tony has enough skill milling, that a dremel would not
be much quicker or easier.
Besides, depending on what kind(s) of milling machine that he has or has
access to, it would be straight forward for him to mill a LONG piece of
brass stock to fit. Then he could cut short pieces for the key blanks.
The rear
picture shows that it is not a fully paracentric keyway. (where
"ridges" and "valleys" of the milling of the keyway would cross the
center
line, making it impossible to insert a very thin flat piece of metal)
Ooh - good catch! That's a really good point.
