nater Posted May 19, 2015 Author Posted May 19, 2015 Nice! No paste wrap?None yet. That is the next step.
nater Posted May 19, 2015 Author Posted May 19, 2015 Ah, I see. Is that wheat paste I see on the spiking?Yes, the hemp twine was saturated with wheat paste before spiking. There is also a puddle of hide glue around the spolette which needs to be dry before the paste wrap.
nater Posted May 19, 2015 Author Posted May 19, 2015 The table in Fulcanelli recommends 1" - 1 1/4" cannule for a 4" shell. I used section of 1" thin wall copper pipe.
memo Posted May 21, 2015 Posted May 21, 2015 nater The table in Fulcanelli recommends 1" - 1 1/4" cannule for a 4" shell where do i find the fulcanelli books or papers. i have heard a lot about fulcanelli but never see it. memo
nater Posted May 21, 2015 Author Posted May 21, 2015 The Fulcanelli papers are contained in Pyrotechnica IX and XI. The proper title is "Tradional Cylinder Shell Construction Volume 1 & 2". The author(s) write under the pseudonym A. Fulcanelli. This is the bible for building shells in the Italian-American style. I do my best to follow it in an attempt to help preserve the art. Ned Gorski has copies to resell at his site, www.fireworking.com The are or were also available through Prometheus Publications, although the owner reportedly has been taking care of ill family members and is not always available with his books to sell.
nater Posted June 6, 2015 Author Posted June 6, 2015 The paste wrap was applied 2 layers of 60 lb kraft at a time, for a total of 4 layers. Each layer was twisted around the spollete forming a crown which will ensure a good seal from the lift gasses. Next step will be lift and leader before firing.
