Make professional looking general purpose tubes or super strength tubes required for special applications such as rocket motors, exhibition tubes, roman candles and aerial shell casings or fire retardant/heat resistant casings used for fountains, smoke casings and propellant liners for hybrid or reloadable rocket motor systems. All for just a little of your time using free paper scrap materials found around the home or office and homemade adhesive that can be made for pennies! Complete, illustrated, 18 page booklet lists several adhesive and fire retardant formulas along with information on mandrel sizes, paper strengths, case rolling, complete charts of proper tube dimensions for all types of pyrotechnic devices, tube cutting to length, and much more! Make tubes so hard they sound like wood when struck together! Cut your tube costs down from dollars to pennies with complete satisfaction and make custom or special sizes not available anywhere else! Why pay the price of commercial tubes?
