Material: Square Rod
Dice, of the highly-polished, ornamental and expensive types, are one of the easiest plastics projects. Making them consists merely of cutting off sections of square rods, polishing and setting in the spots. These are usually made with the point of a drill-bit of the proper size, and inlaid with lacquer. The depth of the drill-cut should be only to the edges of the lips— not an actual drilled hole, and depth should be uniform. Edges should be slightly rounded, but all faces must be square and uniform. Any color may be used, although the greatest number are in ivory, crystal and black. The spots are put in after polishing, and to insure accuracy, should be drilled through a jig.
Material: 1/8" sheet; #6 cyl.
These are popular and easily-made items, the operation consisting only of a little jig-sawing, cementing and polishing, and the material-cost is low. The various card designs—hearts, diamonds, spades and clubs, are cut out of sheet, polished, and then a narrow section of thin cylinder cemented in place in the center of the cut-out. They are particularly suitable for this purpose as they are not harmed by cigarette-ashes, alcohol or water. Another good design is to inlay the figures in the sheet, in contrasting colors. Still another is illustrated in Plate 3X, in which transparent sheet is cemented in a ring cut from cylinder, and ornamental grooves filed or carved.
One very easily-made design of picture-frame is shown in Plate 3G, and this subject likewise provides ample room for individual exploration in the realms of design. The frame shown consists of a base, which in this particular case was metal, but might be either wood or plastics sheet. The picture is held between two sheets of glass of the proper size, which should have polished edges. (This can be done with fine carborundum). The plastic upright at the lower right consists of a piece of or larger square rod, with a slot the width of the two glasses and the picture filed or sawed lengthwise, the upright being fastened to the base by means of a screw passing thru the latter. The clip on the lower left is a section of the same thickness as the right upright, cut from the end of a 1 1/2" or 2" round rod, or sawed from sheet or other scrap, with a similar but deeper slot, and the clip on top consists of half a similar piece, with slot just deep enough not to cover the edge of the picture. In the front center of this clip a hole is drilled and a plated set-screw inserted, cutting its own threads. This serves to hold the entire assembly firmly together, but is not absolutely necessary if the slots are properly sized.
