What would theoretically happen if one were to measure, say, 7" right, left, up, or down from the pin, and THEN do the layout that far away? I've got a few blanks, may try it, but just throwing the idea out there.
Just started drilling, and wanna experiment. Have basic layouts down, but the way I was taught was to ignore the dual-angle stuff, and just measure. I'm gonna self-teach the angle stuff, been reading pinel's stuff.
