A GREAT engineer can build a bridge that won't collapse under any known
condition -- just barely.


Sunday morning at 1 am (before my 6 am drive over to OSH last week) I
spotted Dad's old wheelchair ramp end piece - ramp was disassembled for the
house sale. Green treated 3/4 inch ply, 3' x 2' ...with a ramp lip. Hmm I
thought.

So I fired up the circular saw ...when I should have been sleeping. I cut
three 1-ft wide pieces x 24" deep. Then I thought, hmm? I recall reading
1-ft x 1-ft, so I cut them in half . Mistake.

18" length would be a minimum.

A small strip, or small chock block, would also be good. We kept pushing the
dang plane off the front end of the small 1' x 1' pad. Doh! :-)
