David, thanks for the update. We have a term that we use around here “editor math” … editor math is found more in the realm of “fuzzy numbers” that were so popular just a few years ago.

So, while I can very accurately write you a story about woodworking, numbers & calculations — not so much!

Thanks again …

I could not get the king crown to work with the measurements given. Raising the blade 1.5 ” then setting the angle to 22.5 deg did not give me an intersecting cuts in the center of the 3″ cube. I found if I raise the blade to 1 5/8″(1.625″) then 22.5 deg angle it works.

The math works out too ! I assume you want all the cuts intersecting in the center of the 3″ cube ( or 1.5″) therefore hyp = 1.5 / (cos 22.5 ) …. or

hyp = 1.5 /(cos 22.5) = 1.623 inches. This rounds nicely to 1 5/8″. Of course this

will only work if your starting block is a 3″ cube !!

Where: hyp is the height of the blade before the tilt which become the hypotenuse of the triangle when the blade is tilted to the 22.5 deg angle.
