Bevel angle heighth

[qdod]

Trying to find a formula to calculate how high the primary bevel angle will go on a blade based on the blade thickness and blade width???

Anyone have any suggestions ???

Trigonometry?

Trigonometry?

x2! Soh Cah Toa and the Pythagorean Theorum.

Primary bevel length= hypotenuse
Blade edge to back length(blade width)= adjacent side
Blade thickness = 2x opposite side

Google something like “right angle trigonometry calculator”.

Just remember that two right angle triangle makes the blade shape unless it is chisel grind

Nope.

The primary grind is where the blade first begins to thin to where the edge grind begins.

Let's for the sake of argument, say the blade in question is zero ground (no edge bevel).

The bevel length IS the hypotenuse of one of the two triangles the grind forms.

The length of the adjacent side is the length of the blade edge TO WHERE THE PRIMARY LEVEL BEGINS. And that is ONLY if we are looking at the angle at the edge. (The "half thickness" could be the adjacent side also. Though in this case it most likely isn't.)

And half of the width at the point where the primary grind begins would be the length of the opposite side.

Close.

What are you trying to do with the info? You want to know the angle subtended for a given width and thickness ? Angles don't have height(or length or width) so there is a bit of ambiguity in the question.

Said another way, the height should be 1/2 of the blade thickness. If it is a chisel grind the height of the triangle is the thickness of the blade. Ditto for your grind angle, which is actually the important variable to determine to find your answer.

Here. Go nuts.

And, just to be a jerk...it's in my contract....it's "height"
