, The primary may be wound on roundtubes made of two layers of cardboard glued together. Fig. 21.The tubes may be made up over a cyjindrical form such as isrepresented in Fig. 22. This form is made with a diagonal cutas indicated at cc^ and may be so constructed as to serve forwinding the primary,… … fJA Fig. 22. Method of Making CardboardTubes end marked 8 and at the opposite end to allow the two wedge-shaped portions to be pulled from the finished coil. This samecylinder might be adapted for winding the secondary coils if they are to be wound by hand,but the easiest method of wind-ing the…
