Why when I set my chop saw to cut a 50 degree angle, is the angle on the wood @ 40? If I set it to cut a 30 degree angle is the angle on the wood @ 60. The angle is always opposite but always totaling 90. Why does it not cut the angle I set it for, 60 cut 60. Or if I want a 60 degree cut do I and everyone out have to set the saw at 30? Everyone probably thinks I'm a nut and this is driving me nuts. Thanks once again for everyone's help.
