Twenty-gauge copper is required for this problem. The operations are
similar to those already described; but the cutting and bending are
much more difficult. After determining the design it will be necessary
to make a drawing showing fully developed surfaces, as illustrated
in the detail of the corner. The four corners must be marked and cut
exactly as shown in the drawing. A piece of hard wood is then cut to
the size of the top, 5 inches square in this case, to be used as a form
on which to bend down the sides and turn the flanges. If the corners
are correctly cut the parts will fall naturally into place, to be bored
and riveted, as the drawing plainly shows. In order to protect the
tablecloth, the under side of the rivet holes should be countersunk so
that the ends of the rivets may be finished smooth and flush with the
under surface. As an additional protection, a felt mat may be glued on
the bottom.
