FWW #161 (February 2003) pp. 36-41
There were some plans for sawhorses in a fairly recent issue of FWW
which were designed by Chris Becksvoort.
I built the low one as I like to place my foot on the board to be cut
without giving myself a hernia
I drew it up in CAD and I can send you the drawing as dxf or dwg if
you like.
