dagabu Posted June 1, 2011 Posted June 1, 2011 I am looking for ideas for making horse tail shells. I have made several falling leaves shells and have made weeping willow shells like this one... http://pyrotechnics.no-ip.org/files/horsetail.jpgThe question is, will this work as well for 1" stacked comets for a Horse Tail shell? -dag
DeepOvertone Posted June 1, 2011 Posted June 1, 2011 Whats the difference in a willow and a horse tail? Isn't a a willow usually a softly broken round shell with some sort of tailed star? VS a horse tail that is a canister shell that has the stars gently ejected from one end?
Algenco Posted June 1, 2011 Posted June 1, 2011 I put the stars in one end, I also cut most of the vertical strings at that end so it pops easily
dagabu Posted June 1, 2011 Author Posted June 1, 2011 I put the stars in one end, I also cut most of the vertical strings at that end so it pops easily Thats kind of what i was thinking too, just like a falling leaves shell... -dag
guntoteninfadel Posted June 2, 2011 Posted June 2, 2011 Mine, which were not supposed to be horsetails but turned out that way, were just pulverone and stars mixed together in a cannister. My cannister was not bound very well with either pasted strips or string and the charge just blew out the end. Made a GREAT horsetail effect but I was shooting for that round flower. Back to the building stage.
Algenco Posted June 2, 2011 Posted June 2, 2011 (edited) Break them on the way up I have a bunch of spiral wound tubes that will be used for 4" waterfall/horsetail cans, simple and quick. Edited June 2, 2011 by Algenco

I have a bunch of 3" ID 6" long spiral tubes from photo paper cores that sound a lot like what you have. I bet they would work well huh? -dag
Bonny Posted June 2, 2011 Posted June 2, 2011 I think your diagram will work well for a horsetail. With the lower portion reinforced the shell should blow out the top. As Algenco suggested, breaking it on the way up is a good plan, but with the design as such it shouldn't really matter as the blast will be out one end anyway.I made a few ball shells more or less the same way (burst in one half and stars in the other) and they worked well.

Thats what I did, made them like the drawing and will spike them with 24 verts, half way up and cut all but 4 verts after pasting the shell and will peel them off. -dag
markHE Posted August 27, 2012 Posted August 27, 2012 Just a quick idea, couldn't you use a disc with flaps like a mine? The pressure would build op better so theoretically you could use less blackpowder for the burst.

Yes, absolutely, but with the four strings hanging over the top, you have a fully functional shell that will withstand the lift of a rocket. -dag
