If you want a super accurate angle you setup a sine bar as your
reference, and then tram the tilted head on the sine bar to get it
precise.


Yup, but I seldom do angled work that precise, and if I do, I just use
the sine plate to angle the work to the bed.


I generally program a ball end mill to hemstitch the angle onto the
workholding fixture using X Z or Y Z stepover.

Takes a while but comes out dead nuts.

That's dandy for production work, but for those of us doing a one or two
off part for our own projects we usually aren't doing CNC and we also
can't afford to be making dedicated fixtures we'll never use again.
