I've posted this before, but just ran across it again. Very
inexpensive, and work nicely. I make mine 100% out of plywood - glued
laminated. Use the same principle on glue jigs, planer sled, etc. If
you've never made one, the first one will seem a bit complicated - it's
not - and the rest will seem simple. You can even fancy 'em up, if you
want.

We will never have great leaders as long as we mistake education for
intelligence, ambition for ability, and lack of transgression for
integrity.
