THINGS TO MAKE.



I. A SAWING TRESTLE

A strong and stable sawing trestle is one of the most important accessories
of the carpenter's shop, whether amateur or professional. The saw is
constantly being used, and for it to do its work accurately the material
must be properly supported, so that it cannot sway or shift. Anybody who
has been in the habit of using a wobbly chair or box to saw on will be
surprised to find how much more easily wood can be cut when resting on a
trestle like that illustrated by Figs. 1 to 3.

The top, a, of the trestle is 29 inches long, 4 inches wide, and 2 inches
thick. At one end it has a deep nick, to serve much the same purpose as the
notched board used in fretworking; also to hold on edge such things as
doors while their edges are planed up. Pushed back against the wall the
trestle is then "as good as a boy."
