Angles and settings on the miter saw
I have posted this info a few times here but I'd like some comments on it: The settings on the miter saw are different than the angles cut on a piece held against the back fence...except at 45 degrees where they are the same. The settings on the mitersaw must be subtracted from 90 (degrees) to obtain the actual included angle on the workpiece. Example a 22 1/2degree setting on the mitersaw produces a cut or angle on the workpiece of 67 1/2 degrees. This might be a source of confusion :blink: for folks just starting out. Same thing on the table saw, a miter gauge set to 30 degrees will result in a 60 degree cut angle on the piece. Same as the miter saw, 90 minus 30 = 60.
So "settings" do not equal "angles".
A little more info while I'm here. A circle contains 360 degrees , and a triangle always contains 180 degrees, whether it is acute,(right has a 90 degree corner), or equlateral. So the sum of the included angles in any triangle will be 180 degress. And finally a 345 triangle will have a 90 degree or square corner. Any multiple of these dimensions will result in a triangle with a square corner. Example: a triangle with sides of 9, 16 and 25 will also have a square corner or 90 degrees. Or 3 squared, 4 squared and 5 squared. This is useful in the field to determine if the site layout of a building is square or rectangular. I have used 3 100' tape measures simultaneously to do this. I hope that this is useful.:thumbsup: bill
