Challenge Winner! 

Last week we issued a challenge to "stump our experts" with a question about woodworking fasteners.  Bob Thomas of Cherry Hill, NJ did it. 

Question:  What simple tool or principle is every wood screw fashioned from?

Answer:      The simple tool is the "lever".  A screw, if unrolled and flat, looks like a wedge.  This screw wedge, when turned into the material, works as a continuous lever.  Instead of an "up" or "down" motion, however, twisting is the applied power and the movement of the screw head inward is the work.  Friction is what keeps it in place.  The principle is really a mixture of physics and sawdust.

Congratulations, Bob!  We appreciate the education and your response.
