Hi,

New to the forum. I made a Chord-Tangent angle compensation sliding-diagram by GeoGebra. Don't know it's useful or not. I post it on forum for someone who is interesting.

Regards.

I add Dutchman's Angle Setup formula here. This is his origin model, also my calculator.  Present his theory only, can not be apply if you can not find out real Projection & Jig rotate radius.

If you don't use chord angle as second bevel, set thickness t as 0.

Add parameter input box of "Blade Angle Setup", "SVM-45" and "SE-77" version.  Big thanks to cbwx34 for reviewing, testing & suggestions.
