just as important in these small accessories as elsewhere. When you have cut sufficient 14 by l pieces to make one-tenth inch thickness, measure them against a measure and you will then get the average thickness from the following tuble:No. to 0.1 inch Thickness. 20 .005in. 25 004in. 83 003in. 50 002in. Clips to hold the condenser are shown full size in the diagram. ‘These are made from 28’s hard sheet brass cut as shown, bent up, and bolted to a slip of ebonite 1%in. long by fin. wide. When experimenting, several condensers may be put together and held against the outside of the clips by a small rubber band passed round the lot. Instead of cutting away the square corner of clip it could be bent up along A and a depression made tq hold a grid leak or resistance. Good values to make besides those less than one plate are 1, 2, 3, 4, 5, 6, 8, 10, 12, 16 plates. Next week will be described a simple method of finding the capacity of the condensers after they are completed, which is the only satisfactory way of determining value.
