Rooster Posted January 24, 2006 Posted January 24, 2006 Blindreeper: Name of composition: Cast Iron DriverComposition Type: DriverCreator: Unkown - AFN IVColor/Effect: Long branching gold sparks Meal powder - 80-16 Mesh cast iron or steel - 20 The iron is important. Pure iron will not branch like cast iron as it contains carbon. Iron up to 7% carbon produces this effect. Iron should be treated with wax or linseed oil. I obtained my cast iron borings for free at a engine building place. They often shave the heads of engines and have perfect iron turnings and often have a slight oil coating on them which is perfect. Mine just passed through a 17 mesh screen (window screen) I am using this in my drivers for my 14" girandola. Precedure/Preparation: Screen the meal and iron borings together or shake together in a ziplock bag for a minute or two. I will post pics when I let it off! +++++++++++++++++++++++++ Frkonaleash1010: Damn you, I seriously was gonna post this tommarow as a fountan mix. I use a ratio from the PFP of 76/24 though. Works perfect for a fountain mix but even at 76/24 if they tip over they zip all around the floor. So 80/20 can deffinitely have some thrust to them. And I have gotten a 12-15foot fountain out of this comp in a 3/4 inch tube....so the trail of sparks from the driver is going to be severely long. Guess I shouldn't video tape my lame fountain and post it next to your girandola. lol ++++++++++++++++++++++++ Defiant Pyro: I tried this mix (in a fountain). It made a great shower of bright gold sparks. I got iron shavings from a buddy who works at a car shop. I acually still have some of the mix in a plastic container somewhere around here. Perhaps I will make a quick fountian and submit a vid for this page. +++++++++++++++++++++++++ pyrohawk: I hate to sound stupid but as I've never made or really heard of a Girandolla untill a couple days ago.... I have no clue what a driver is! I assume its the rocket that turns it? +++++++++++++++++++++++++ Frkonaleash1010: A driver is nothing more than a rocket with an effect in it. In this case orange branching sparks. In effects like girandolas or wheels you need drivers not just rockets or it would look pretty boring........ ++++++++++++++++++++++++ Mumbles: Does this driver need to be choked at all? I'm going to try a small wheel later, and I plan to use this. I have much finer steel, so maybe my tail just wont be as long. I'd tried stuff like this before, it works fine. It's between 50 and 100 mesh. ++++++++++++++++++++++++ ftwchriso: You guys say its got a golden effect.But is it quite similar to the tigertail stars? ++++++++++++++++++++++++++ Mumbles: I'm going off other similar stars I've made for this. They are not all that similar. The Steel produces a spark. It is bright and short lived(as compared to charcoal). The charcoal stars produce more embers. They are usually a little more orangy to me. Looking at a picture they make look sorta similar, but the actual effect is quite different if you ask me. The charcoal star sparks kinda float around, while the steel sparks just streak. ++++++++++++++++++++++++++ Frkonaleash1010: Yes this composition most deffinitely should be choked. I use a 1/3rd diameter nozzle/choke on my fountains and they have one hell of a thrust. I am not sure what you would want to use on a driver though. The sparks probably just wont be as big and as long of a tail. ++++++++++++++++++++++++++ Mumbles: Success! I made a beautiful spinning wheel display. I made it with the m-80 tubes from cannonfuse and a paint stirrer. The tubes were choked 1/2 the way, so 3/8". I would of had it beautiful, but my friend broke the connecting fuse off. The 2nd tube did fly off near the end, but I attribute that to bad attachment. I was using copper wire and a little string. Perhaps glue next time. I got probably a 3 foot spread in either direction from a wheel no more than a foot across. +++++++++++++++++++++++++
