SSHPyro Posted March 29 Posted March 29 I just milled my first star comp tiger tail, I used 44% KN03 44% Charcoal airfloat 6% sulfur and 6% dextrin. I milled this for about 5 hours and went to test it today in its powder form and it will not light no matter how hard i try, I hold my torch to it and it looks like tiger tail when I'm torching it but it will not combust. I'm using charcoal from hardwood. Should I mill it more?
Richtee Posted March 29 Posted March 29 I’m no expert but seems a bit high on the charcoal..or light on the oxidizer. Poh-tato Pah-tahto.
All10Fingers Posted March 30 Posted March 30 Tiger tails need a little wind to compensate for the lack of oxygen get. Usually this comes from flying thru the air. Once you make some stars with it try shooting some out a small paper tube and see what happens
Zumber Posted March 30 Posted March 30 Make pumped star out of it using 75/25 water alcohol and dry it out then test It will work well. 1
Arthur Posted March 30 Posted March 30 Make a star or ten. DRY them to constant weight, then launch one into the air conventionally. Many compounds fail because they are 5% water that hasn't yet dried out.
SKC Posted April 4 Posted April 4 It's a common phenomenon. Make star from the mix, dry them well. then test.
Arthur Posted April 4 Posted April 4 The tiger tail effect comes from it being an under oxidised mixture totally reliant on the star being travelling through air. To make it function with it's odd mixture proportions it needs to be a properly formed star completely dry, and launched from a tube. Once you have a successful star, try to select the best available charcoal. Willow and Red Alder make good BP, try some under milled for making effects. Form your star and weigh it (or ten) then leave it to dry. It's actually dry when it remains the same weight for two weeks. Gentle heat will assist with drying. Quote
