Holes are bored with a small bit in the grooves in the legs, 1/2" in from the sides, as shown. These holes are for the round-head screws which hold the steps in place. The steps are held in the grooves of the legs with glue and 1" No. 6 round-head blue screws.
Plate 28.
The dowel sticks are now cut 8-3/4" long from a 1/2" dowel and, after all pieces of wood are carefully sanded with No. 1 sandpaper, the step ladder is assembled.
A 3/4" brad should be driven into the edge of the rear legs so that it will penetrate and hold the dowel in place.
A piece of small chain should be fastened to each front and rear leg, as shown, of a length sufficient to have the front legs of the ladder set flat on the ground. Also take care that the two chains are even with each other and parallel with the ground. No further finish is required.
