The nails used on the box were one-inch brads.
The holding power of flat-head nails is of course much greater than bung head, but in this case the box was to be squared up after nailing, exactly as if it were a solid block of wood. This meant planing the sides and ends, and as the nails would ruin the plane iron, they were all sunk below the surface with a nail set or punch. ([Fig. 135]). This is a useful tool, but not absolutely necessary, as for light work a wire nail, with the point ground flat on the grindstone, will answer the same purpose. A carpenter frequently uses the edge of a flat-head nail instead of the punch.

The Correct Way to Hold the Chisel.
The box was assembled by nailing together the sides and ends. The bottom was next put on, holding the try square along one side and end to make sure everything was square, and last of all the two partitions were pushed down into their grooves, and tied in place by one brad from each side. Next, all nails were set, and the outside tested with the try square and trued up with the plane.
