"The Boy Mechanic: Volume 1 700 Things for Boys to Do"

The
frame as shown in the sketch was devised and its chief advantage
lies in the fact that when not in use it can be compactly tied
together and stored away in a closet.
Almost any wood may be used in constructing this frame, but yellow
pine is the best, as it is easily obtained and at the same time
very well suited for such work. All pieces are to be dressed on
all sides.
Two upright pieces are cut from 3/4 in. material 2 in. wide and 5
ft. 9 in. long and two blocks are fastened on the ends of each
that are to be used for the bottom, as shown in Fig. 1. These
blocks are each 2 by 6-in. and 1/4 in. thick. The base is made
from a piece 3/4 in. thick, 3 in. wide and 5 ft. 4 in. long. A
crosspiece 3/4-in. thick, 3 in. wide and 12 in. long, cut in the
shape shown in Fig. 2, is screwed on each end of the base with
3-in. wood screws, as shown in Fig. 3. Four blocks 1/4 in. thick,
1 in. wide and 3 in. long are nailed to the sides of the base
piece parallel with and at a distance of 2 in. from the end of
same. This forms a slot, Fig. 4, to receive the pieces nailed to
the ends of the uprights.
