I just know there is a spreadsheet/calculator or software app. to calculate various parallel heel graver dual angle fixture settings, inputting different lift (relief grind), face angles ect. to give heel yaw angles...example inputting 4 degrees lift, 105 degree v point, 55 degree face to find optimum relief grind angle and optimum heel angle and proper heel yaw angle....

some time ago, john henley sent such a calculator to this forum. try the search feature to see if it is there. i have it in my system, but do not know how to copy the link to it.

Mostly it is an elementary geometry problem. This is what I do. After I have ground the face, I set the angle of the heel I want and bring graver down to rest on diamond wheel with the rotation free to turn. I then rotate the dual angle fixture so that there is complete contact along the cutting with diamond wheel. That gives me the angle to set both sides of the heel. Something I found that helps me with correct graver geometry is to coat the graver with a Sharpie marker before you grind the heel. This will show the heel clearly. It also helps my old eyes help to see clearly if the heel is ground correctly.

Is there a problem with the down load, I can only get page 1 pg 2 and 3 are blank
not sure, but the copy i have is only 1 page. that page does the calculating automatically. all one need do is enter a few numbers. nuttin else is needed as far as i know.
