...then check your math and measure AGAIN before cutting.
I just spent the last 3 1/2 hours milling the parts for 5 MDF doors to go on my new shop cabinets...and made every one of the panels 2" too short. Of course, I didn't realize this until after they were all raised.
I guess I need to change my AutoCad dimension setting to just inches, instead of feet and inches. Obviously I've become mathematically challenged.
