not 90* to the serface? I need to counter sink then drill a through hole at a 45 degree angle. I only have a few hours practice in SW and this was not covered in my book. I've spent several hours on this and am stumped.
Here is the machined part I did on a manual mill. I'm drawing it in SW for practice.
The bottom right picture shows the "through hole"
The top left shows the "counter sink" along the same axis as the through hole.
The problem I have is I can only locate the holes correctly from the 45* edge.
The holes are at a 90* angle to the 45* angle in the top right picture, the counter sink would be on the right side.
I hope it makes sense, thanks.
