Svimmer Posted December 20, 2017 Posted December 20, 2017 Hi any good explanation on how to make portfire's. Are they just rammed or do i just fill a tube with composition.
OldMarine Posted December 20, 2017 Posted December 20, 2017 Here's a quote from Mike Swisher on Portfires: "Try this one, originally from Don Beachler of United Fireworks of Dayton, Ohio, published in Hardt: 57 saltpetre 16 sulphur 16 barium nitrate 5 antimony sulphide 1 meal powder 5 wood meal Burning time can be adjusted by varying the amount of wood meal. Roll 1/2" cases perhaps 12 inches long, using 3 turns of 70-lb. kraft and 2 turns of 30-lb., in similar fashion to Niagara tubes. Fill with rod & funnel. A little alcohol may be added to keep dust down and help consolidate. About an inch at the bottom should be charged with clay or sawdust. Fabricate a holder to grip this end; see Kentish for instructions." 1
