| How to find the center point of a circle |

On a pretty regular basis during the construction of my cab, I've found myself needing to find the exact center point of a circle, for example when I've drawn a circle I need to drill out with a hole saw, but need to position the drill exactly in the center to make sure it gets cut out in the right location. I often just eyeball it, or make a bunch of rough measurements. But I just stumbled across this simple method of finding the exact center point with just a pencil, straight-edge (ruler) and compass. Just thought others who don't already know the trick might find it useful. After you do it a couple of times you get very fast at it. You don't actually need to draw complete circles because you can estimate approximately where they will meet and overlap. |

I barely even went to school. ;D As graduation was coming up my school offered after school detentions that students could attend to bring their citizenship grade up. I had to attend more detentions to qualify for graduation than any other kid in my high school. I skipped at least one class almost every single day. Too bad. I could have done high school in my sleep if I had cared. Years later I ended up having to work full-time all through college. I learned discipline way too late in life (and I still only have a modicum of it ;D ). |

Discipline to build yourself a machine is discipline enough. Though maybe you ended up building it at night to make up for shirking in the day! |
