Place your main line from your rod thru the hole of the bottle cap, Tie on a snap swivel to your main line,Add the amount of weight that you wish to use to the snap swivel. or drop the weight into the bottle its self.Drill several about the size of a pencil in the body of the bottle.[be sure to drill one in the bottom or the bottle to relieve the excess water that will collect into the bottle.] Place as many sardines cooked in oil as you can into the bottle. Tie a barrel swivel about 12 to 18 inches above the chum bottle. Tie your leader with the hook that you like to use to the barrel swivel. when you rig is completed it should be similar to a 3-way rig. you now should be ready to tight line fish!
