Hello,

I just joined DIY and I have a question on tools. I am considering
making my own and possibly selling wood guitar tuner buttons. The
problem I have is on the shaft side of the button is a 3/32" x
5/32" rectangular shaft slot with rounded ends.

I was looking at mortising bits but they are just too big. How would
anyone go about making this hole? Thanks in advance for you help.
