Fret end angles.

If you want, you can also angle more on the treble side, and leave the bass side more or less vertical, since the 'feel' of the fret ends when playing is noticed more on the treble side. The height of the fret is a consideration too. A tall fret, beveled at 35deg is gonna bring the bevel in further than a low fret.

1.000 . Tangent of an angle is the ratio of the length of the opposite side to the length of the adjacent side. Tan = Opposite / Adjacent. I ripped this photo from wiki - it's not scaled right for our example. .078 125 / 1. = .078 125. Inverse Tangent of .078 125. = 4.47 Degrees. For ONE side of the blade.

The Groove Weld: A Lesson in Weld Anatomy and Geometry

Bevel angle is the angle at which a single plate is prepared, while included angle is the total angle formed by the preparation of both plates. For a single-bevel groove weld, the bevel angle is equal to the included angle, but for a single-v groove weld, this is not the case. If both plates were beveled at 30-degree angles, the included angle ...

This is all anticipated and allowed for.

Edge Fracture – Is It More or Less Likely With A2 Steels?

After the same number of strokes the edge fracture is markedly less on the flat face of the cutting iron compared to the harder A2 steel from the bevel-up plane (shown in the first two images above) and also on the bevel side of the same iron. I noticed that I had to push harder sooner on the bevel up plane than the bevel down plane because the ...
