Hi All,



Any inexpensive ways for making square holes? 1/4" x 1/4" to be exact.
Current thinking is to just use a round rod and machine the square on
the drive end. But then how do I stop the "prongs" from rotating
around a round rod. There is a reason they used a square rod. {grin}

Dave

get a rotary broach - there are some inexpensive ones for small holes
like you want.
