example a
[0062]A 32¾″‘no brake’ formula thermoplastic polypropylene unpigmented extruded tubing with an outside diameter of 0.890″ and an inside diameter of 0.715″ from Hudson Extrusions Inc.; Hudson, Ohio was used as a hollow tube.
[0063]Both ends of the elongated thermoplastic extruded tubing were closed for safe and effective use wherein at least one end, used as the distal end, is formed as an integrally sealed end without the use of glues or mechanical devices such as screws clamps, end caps, etc. To form the integrally sealed end the thermoplastic tube was heated using a heat gun, such as Intertek VT-1000 heat gun, for about 15 seconds followed quickly by the application of a controlled amount of pressure for about 5 seconds using a clamping device such as a pair of pliers, to bring in contact or pinch together and fusing two opposite sides of the inside diameter of the open end of the thermoplastic tube. The pressure was applied to the outside diameter of the thermoplastic tube at appr...
example b
[0067]A flexible swing stick was prepared as in Example A with a 35″ hollow tube and 243 grams of 5 / 16″ diameter steel balls by B C Precision balls from Amazon inserted into the open end of the flexible tube. A single, ½″ diameter steel ball from BC Precision balls from Amazon was inserted into the open end of the hollow tube. The 8 gram ½″ diameter steel ball prevented the smaller 5 / 16″ diameter steel balls from moving past it inside the hollow tube having an inside diameter of 0.715″. The ½″ diameter steel balls removes the potential of a 5 / 16″ diameter steel ball from becoming stuck or wedged between the outside diameter of flexible grey foam backer rod and the inside diameter of the thermoplastic tube. The function of the 5 / 16″ steel balls plus the ½″ diameter steel ball is to add weight to the flexible swing stick plus the steel balls are able to move freely back and forth inside the hollow tube as the flexible swing stick is swung or oscillated back and forth. A ⅝″ diameter×5....
example c
[0070]A flexible swing stick was prepared as in Example B with 48 grams of ⅝″ diameter steel balls by BC Precision balls and 198 grams of ½″ diameter steel balls from BC Precision balls from Amazon. The ⅝″ diameter steel balls created a louder impact sound than either the 5 / 16″ steel balls or the BB's when the flexible swing stick was swung. The function of the ⅝″ diameter steel balls plus the ½″ diameter steel balls is to add weight. The louder sound of the steel balls making impact with the inside end of the flexible swing stick using just 3, ⅝″ diameter steel balls with the remainder of the weight of steel balls being ½″ diameter steel balls allowed this construction of the flexible swing stick to be lighter in weight. A ⅝″ diameter×5.0″ long piece of flexible grey foam backer rod from M-D Building Product, Inc., Oklahoma City, Okla. was inserted into the open end of the thermoplastic tube and pushed, using a long wooden dowel rod, to the opposite end to be in contact with the ½″...
