I see it very fast Thx Aspirina Lift 3g classic bp 75/15/10.Quick match in a tube, inserted into the holes, and through it (visco/quick match) and covered with duct tape.(sorry for my English) Link to comment Share on other sites More sharing options...
BlueComet24 Posted April 24, 2016 Share Posted April 24, 2016 Your cake was very nice. Did you use pistons to lift the stars? I'd recommend against using metal mortars that are not buried. If a tube in your cake got clogged, it could produce some nasty shrapnel. Cardboard, fiberglass, and HDPE are safer alternatives. Link to comment Share on other sites More sharing options...
lloyd Posted April 24, 2016 Share Posted April 24, 2016 (edited) "Your cake was very nice.

BlueComet24 Posted April 24, 2016 Share Posted April 24, 2016 A sabot increases the diameter of a projectile to the size of its barrel. I'd think piston would be more appropriate, but whatever you say. Link to comment Share on other sites More sharing options...
lloyd Posted April 24, 2016 Share Posted April 24, 2016 Blue, that's the case with some sabots -- most commonly for some kinetic (non-explosive) AP rounds. But, a sabot is not required to surround the projectile in order to qualify as one; they often trail the round. In fireworks, for some hundreds of years, the traditional term used for your 'piston' in fireworks has been "sabot". Some use the term 'wad', but that is also not correct, unless the thing used IS a wad... that is, slightly larger than the gun i.d., and compressed to fit into the tube. A sabot is smaller than the i.d. and is often used to cushion a delicate shell against lift force, or to help uniformly lift all stars in a mine to the same height. Those in mines are often perforated to allow lift gasses to mix in with the stars. I'm not a schoolmarm. You can use the term you wish to use.

What are the compositions?Thx Sparx88!Chemical composition(D1 glitter stars mod):KNo3 - 53%S - 18%C(airfloat) - 11%Al(150 mesh) - 7%NaHCo3 - 7%Dextrin - 4%Boric asid - 1% Edited April 30, 2016 by PiroArt86 Link to comment Share on other sites More sharing options...
lloyd Posted April 30, 2016 Share Posted April 30, 2016 Yup... the gold glitters are among my favorites, too; and I especially like the sodium bicarbonate as a delay agent. LLoyd Link to comment Share on other sites More sharing options...

Sparx88 Posted May 4, 2016 Share Posted May 4, 2016 (edited) Thanks piroart for the D1 comp. I did notice after I asked that you mentioned it already. It's one of the many star comps Ive yet to make. I have made winokur 20 with large flake alum. Not as good as alcoa 120. Needs to get some from hobby chemical supply. Have you tried wino 19? That one uses granular magnal 100-200 mesh and it really flashes big and bright but not as dense. Edited May 4, 2016 by Sparx88 Link to comment Share on other sites More sharing options...
