[view detail]
I hear and I forget. I see and I remember. I do and I understand. Attribute to Confucius (~500 BC). Still true 2500 years later. When I was 7 or 8 years old on a miserable cold gray day in February my parents dropped my brother and sisters off at the Center of Science and Industry (COSI...

Sand Paper Cutter
[view detail]
If you use a sander that requires a rectangle piece of sand paper, this may save you some time while sanding and make use of an old hacksaw blade. I have been using this contraption at work for the last 15 years and never gave it a second thought. Seems to me this would b...

DIY: Carbide line scriber
