dangerousamateur Posted July 7, 2014 Posted July 7, 2014 I could get some gummed paper tape with filament inside. Is this useful for pyro?Normally I only see people use the stuff without reinforcement. It looks excactly like this here:http://www.amazonsupply.com/duck-reinforced-gummed-inches-964913/dp/B0026RHV7A How do you feel about this stuff?
dagabu Posted July 7, 2014 Posted July 7, 2014 I have not seen any serious shell maker use the reinforced stuff, I tried it very early and I experienced a "hose break" kind of shell break. I got a case of kraft tape from ULINE and split it on my lathe then ran it through a gummed tape dispenser for shells. Works fine for small batches, a WASP is better for large shells and larger batches.
MrB Posted July 7, 2014 Posted July 7, 2014 Fiberglass reinforcement. Just as i personally don't use plastic shell components, i don't use fiberglass reinforcements.It's sort of a 2 fold policy. One concern is environmental, this stuff doesn't degrade over time, and will lay around for years to come, making nobody happy. The other is more about the average Joe's acceptance to pyro. Leaving shredded paper around that turns to mulch the first time it rains isn't going to upset the average Joe that much. Leaving bits of fiberglass and plastic everywhere, thats a different story. If you feel you need the reinforcement, use natural fiber twine.B!
dagabu Posted August 3, 2014 Posted August 3, 2014 Dagabu how did you go about splitting the roll? I put it on a 3" mandrel with end plates, chuck it up and use a rotary cutter blade to split the whole roll at once. Slow speeds on the lathe, sharp blade, perfect 90° to the bed or you get a tapered roll.
Arthur Posted August 3, 2014 Posted August 3, 2014 (edited) The very lack of wet strength of real paper is what makes brown paper stick round ball shells with little creasing. anything with fibre reinforcement risks laying less well and making lumpy looking shells. PS -biodegradable is good, you will never find all the bits of the shell body so make what you leave naturally degrade. Keeps the country clean and the neighbours happy. You will not get caught for making fireworks til you upset the neighbours or your own family. Edited August 3, 2014 by Arthur
