Figure 8. Propeller type surface plug. Chapter 4 Fresh-Water Plugs #2 Another surface plug which has proven effective over the years is the "propeller" type, Fig. 8. This plug has one or two propellers, usually one at the head and another at the tail. When it is retrieved or jerked the propeller blades revolve and throw a spray. Although screw eyes can be used to hold the propeller blades, a much better and stronger method is to rig this plug with a wire running through the center, as shown in Fig. 9. When making this plug, drill a hole through the center, from the head to the tail. If you have a drill press, do this with an extra long drill and a jig which will hold the plug body in the correct position. You can also drill such a hole very easily with a hand drill—if you do it before the plug is shaped. In other words, drill the hole in the rectangular block of wood through the center, then rasp and file to finish the plug. To find the center of the block of wood, draw an X from corner to corner.
