Thanks, but not what I had in mind ...
I'm seeing the bevel as a pivot of the saw and motor on some shaft
that's horizontal with the table. Where the center of rotation is located "may" affect the length of the leg on a miter...I donno? I would not think at least on the saws I'm familiar with, that the blade plane is the center on which it rotates, rather offset from the blade by some amount. This I believe, is what causes a bevel miter to change it's leg length over a straight down 90 degree miter....again, I donno? My degree is in ART/Design not engineering.
My trigonometry expertise is very faded after all these years.
Any engineers listening to all this? WillemJM ?
The answer to your question will only be as detailed and specific as the question is detailed and specific. Good questions also include a sketch or a photo that illustrates your issue. (:< D)
