The method of constructing this size board is similar to the other two types. (Plate 24.)

This size board is suitable for children from six to eight years of age.

The top is made 3/4" thick, 9" wide and 30" long. The dividers are set with a 4-1/2" radius and an arc is struck to touch the end and two sides of the board. A similar arc is struck at the opposite end with a 3-1/2" radius.

These arcs are connected with a straight line, and the outline is cut with a saw and finally planed to the lines. The curved ends can be cut with a turning saw and finished with a chisel and file.

The upper edges are slightly rounded with a file and sandpaper.

The legs are next cut to size, two being 3/4" × 1-1/4" × 27-7/8", and the other two 3/4" × 1-1/4" × 29".

One end of each is rounded by striking an arc with a 5/8" radius, at the extreme end. The other ends of the legs are cut at an angle, as shown in the drawing.

Holes are bored in the rounded end of the short legs, 5/8" from the ends, of a size that will take a 1-3/4" No. 10 round-head blue screw.

Another hole of similar size is bored 11" from this. These holes are all 5/8" from the edges.

On the other two legs the only two holes necessary are bored 12-1/2" from the rounded ends.

The shorter legs are attached by screws to a cleat which itself is screwed to the underside of the board, 4-1/2" from the large end. This cleat is 1" × 1-1/4" × 6-3/4" and is held in place with glue and 1-3/4" flat-head screws, countersunk. Two of these screws are sufficient.

The separating piece at the other end of the legs is 3/4" × 1-1/4" × 6-13/16", and is held in place by 1-1/2" brads and glue, and is attached 3-1/2" from the ends.

Two separating pieces are next made for the long legs, 3/4" × 1-1/4" × 5-1/4", and these are attached in the same manner as the pieces between the other set of legs.

A cleat 1-1/8" × 1-3/8" × 5-3/16" is attached with glue and 2" flat-head screws, 5-1/2" from the small end of the board. This holds the short legs in position.

The wood button, shown on the drawing for the Size A ironing board (Plate 22), is attached to this cleat and prevents the board from collapsing.

All pieces should be thoroughly sandpapered with No. 1/2 sandpaper before being assembled.

No further finish is necessary.
