A quick and dirty shop tool I made this evening for an upcoming project that requires a keyway in a blind hole (the reason it is so long)
I did a little you tube searching for a solution and made my own rendition for an old bolt, a 1/4-28 set screw and a small chunk of 1/4 hss.
The keyway I need to cut is actually 8mm, so it will take 2 passes, but it does go pretty quickly in aluminum, actually a lot quicker than expected
There is a short video of it in action on a piece of scrap for those that care to see.
