I’m designing a waste board where I am boring several holes for T-nuts. All the holes are through holes of same size diameter. The holes are also counter bored so that the T-nuts do not extend above the bottom surface of the waste board.
Here’s the problem. 9 of the holes will not have a recessed bored in them nor have T-nuts inserted. These 9 holes will be for securing the waste board to an aluminum plate from the top.
I need to flip the waste board over an counter bore the nine holes. So my question, how to zero the X & Y axis so that I can accurately target the 9 holes.
