heres what i did (feel free to point and laugh). working in construction for years taught me that direct transfer is the most reliable (unless of course you have a table with answers) as each measure you make and record each number can introduce human error. the simplest thing for me without having tables was to draw it out with as few measures as possible. i drew a line perpendicular and square to the edge of the paper, marking it at 30mm. i then drew a semi-circle with a diameter of 16mm to represent the frame/spine, centered on the perpendicular line. then just lines (i only drew one line so as to get my angle since that's all i needed but drew in the second for the purpose of explaining) to connect the "cutting edge" and "hone contact" on the frame/spine. i measured the angle that corresponds to being between the spine and blade face which gave 75 degrees. the angles in a triangle add up to 180 degrees so i took the 75 degree angle from each corner since they are the same, giving 150. the cutting angle that was left was 30 degrees. (plus or minus) simplest way for me but obviously not as accurate as a table. i love the redneck protractor tom! in theory that should give a close measure of the half angle but those bubbles always lie! i havnt met one yet that told the truth, the whole truth and nothing but the truth
