Same message with a better Subject heading:
Looking at the profile or cross section view of the long edge of a 3/4-inch
thick board, the edge drops down at a 90-degree angle from the face and the
drop
down is about 1/4-inch. From there the edge angles about 60-degrees inwards for
a distance of about 1/8-inch, then it angles straight down again for about
1/16th inch or so then angles about 60-degrees back out towards the face of the
edge. At the edge it drops down at 90-degrees for about 1/16-inch then angles
back inwards about 60-degrees for about 1/8-inch and from there it drops down
straight for about the last 1/4-inch of thickness of the board. The mating
piece
is the mirror image of this cut.
Hope that helps. Essentially, the cut is a zig-zag except that there are small
flats where the zig turns into the zag. Well if that last sentence doesn't
confuse you I don't know what will.
