I don't think dimensions are needed - the only critical measure seems to be the angle.
Feeling a bit thick here. I see the loupe, the 118 degree Tee, the small wheel on either wing(?), and the stone. But I don't see how all that goes together to sharpen a bit. Perhaps a few words of clarification for an apprentice chip sweeper (ha! you didn't know CSs had apprentices did you

).

Hmmm, I may do that just for the practice.
robotic regards,
