I am building Harold Halls Drill grinding jigs from his book on Tool and Cutter Sharpening. The small drill jig is made of 2 square blocks that have a 90° V milled in them corner to corner. How do I set up to cut the V with a regular milling cutter? I am trying to use my mill vise with its rotating base, holding a 3 mill vise, holding a 2 machinist vise, holding the block.
Ive set the block to be milled in the 2 vise level with its base, and mounted the 2 vise at 45° in the 3 vise. I then mounted the 3 vise in the mill vise at 45°. That puts the plane of the V parallel to the mill table. I would think that rotating the mill vise to 45°would align the V with the y axis and Id be ready to cut, but it doesnt look right. What am I missing?
I can take a picture of my setup if necessary, and post a picture of the jig, also.

The difficult takes me a while, the impossible takes a little longer.
