Spiral Cut from Cardboard
A novel attraction for a window display can be made from a piece of stiff cardboard cut in a spiral as shown in Fig. 1. The cardboard should be about 7 or 8 in. in diameter. Tie a piece of string to the center point of the spiral and fasten it so as to hang over a gas jet, Fig. 2. A small swivel must be put in the string at the top or near the cardboard, if it is desired to have the spiral run for any length of time. The cardboard will spin around rapidly and present quite an attraction.

A Workbench for the Amateur
Detail of the Bench
The accompanying detail drawing shows a design of a portable workbench suitable for the amateur woodworker. This bench can be made easily by anyone who has a few sharp tools and a little spare time. If the stock is purchased from the mill ready planed and cut to length, much of the hard labor will be saved. Birch or maple wood makes a very good bench, and the following pieces should be ordered:
4 legs, 3 by 3 by 36.
2 side rails, 3 by 3 by 62-1/2 in.
2 end rails, 3 by 3 by 20 in.
1 back board, 1 by 9 by 80 in.
1 top board, 2 by 12 by 77 in.
1 top board, 1 by 12 by 77 in.
2 crosspieces, 1-1/2 by 3 by 24 in.
1 piece for clamp, 1-1/2 by 6-1/2 by 12 in.
1 piece for clamp, 1-1/2 by 6-1/2 by 14 in.
4 guides, 2 by 2 by 18 in.
1 screw block, 3 by 3 by 6 in.
1 piece, 1-1/2 by 4-1/2 by 10-1/2 in.
Make the lower frame first. Cut tenons on the rails and mortise the posts, then fasten them securely together with 3/8 by 5-in. lag screws as shown. Also fasten the 1-1/2 by 3 by 24-in. pieces to the tops of the posts with screws. The heads should be countersunk or else holes bored in the top boards to fit over them. Fasten the front top board to the crosspieces by lag screws through from the under side. The screws can be put in from the top for the 1-in. thick top board.
