ATTRACTIVE dust covers form any household or hobby work room uses can be made easily from clear sheet celluloid sold by auto supply stores. Sheets as large as 20" x 40" are available. This size is more than adequate for a variety of items: kitchen food mixers, pastry, microscopes, etc.

To make a cover, place the object on a sheet of paper and draw an outline around it. For some articles a cylindrical cover is suitable, for others a dewdrop shape is better. Several styles are shown in Fig. 1. Measure the circumference and cut a piece of celluloid 54" longer and of width equal to the height of cover required. Bend the celluloid into a cylinder, paint the ¼ " lap allowance several times with acetone. Clamp the two ends together between two pieces of wood and allow to dry for an hour. Reinforcing of the top and bottom edges is necessary to obtain sufficient rigidity. This is readily done by using No. 12 hard-drawn copper wire as used for radio aerials, or other wire of suitable stiffness. Measure a piece 1" longer than the circumference, and bend it to the original pattern. Fit the wire snugly just inside the edge of the cylinder. Mark the amount of overlap on the wire and file off the ends in a long bevel. Solder together as in Figs. 2 and 5. Make a similar reinforcing ring for the other edge.
The wire rings are fastened in place with cement made by dissolving scraps of celluloid in acetone to a syrupy consistency. Insert the ring in the cylinder and with a camel's hair brush, as in Fig. 6, flow in the cement between the wire and the celluloid. Repeat this several times, allowing time for the cement to dry between applications until eventually the space has been filled, as shown in Fig. 3. When the cement is thoroughly dry, attach the top by laying a piece of celluloid on the table and standing the cylinder on it. Lay a board across the top and weight it sufficiently to press the lower edge of the cylinder firmly against the sheet. Flow a somewhat thinner cement into the joint between the wire reinforcing ring and the celluloid top.

Go around several times, and be sure the joint is well filled. Allow to stand an hour to harden, then trim off the surplus with a sharp knife as in Fig. 7. Sand the edge smooth with fine sandpaper. No handle is really needed, but if desired a neat handle can be made by bending sheet celluloid as in Fig. 4 and cementing on top.
