What kind of bonehead mistakes have you made over and over? I’m not talking about accidents or things that you do from lack of experience, like breaking a bit using default settings, but mistakes that you should have learned from the first, second, or third time.
My bonehead mistakes are:
-Trying to put the vacuum hose back into the dust shoe, even though it is a stupid-tight fit and will likely move the spindle.
-My personal favorite apparently, since I just did it AGAIN tonight, is to draw something up, like a box to go around an outlet box, and not change it from “cut on line” to “cut outside line”. After an hour of cutting, I take the parts out and there’s a 1/16" gap between the pieces, and they are 1/8" too short.
Tell me I’m not the only bonehead around here, what mistakes have you made that you didn’t learn from?
