pillyg Posted January 29, 2011 Share Posted January 29, 2011 Hi, i have rockets that work good but i want to add a tail. What would be the best thing to use. Ti, FeTi, Al, or Fe? Link to comment Share on other sites More sharing options...
Guest no6 Posted January 29, 2011 Share Posted January 29, 2011 Why are you a lower case i? Link to comment Share on other sites More sharing options...
NightHawkInLight Posted January 29, 2011 Share Posted January 29, 2011 It's a matter of preference and desired variety of tail, but Ti gives a very nice effect. Only add Ti to the increments of comp that are above the spindle, it will still give a good tail but without chewing up your tooling. Link to comment Share on other sites More sharing options...
Ralph Posted January 29, 2011 Share Posted January 29, 2011 I agree with NH Ti is certainly brilliant personally ive never been sold on FeTi. al can look quite decent especially if you use a glitter formula in your delay section(one with no or little amount of delay agent so as not to catastrophically clog the nozzle) though my personal favorite when not showing off to anyone is good old iron (or steal or cast iron what ever ive got my grubby fingers on at the time) its gentle golden sparks branch gracefully as the rocket takes off leaving nothing but a golden smear through the sky , also its cheap Link to comment Share on other sites More sharing options...
dagabu Posted January 29, 2011 Share Posted January 29, 2011 You know? I have a hard time getting iron around here. I can get Ti, MgAl, Al but good old iron is tough to find. We dont have any brake turning shops anymore. Sigh. Link to comment Share on other sites More sharing options...
pillyg Posted January 29, 2011 Author Share Posted January 29, 2011 so if I put the tail comp above the cored fuel, it will still make a tail even though the main fuel doesnt have any glitter? For Iron, you can get it from instant cold packs. I made a video of it.http://www.youtube.com/watch?v=gcsJWerUi68 (second rocket) Link to comment Share on other sites More sharing options...

If you can still see the spindle when you are done pressing the top increment of fuel, the next increment can have the delay with metal in it and it will light at the same time as the main fuel starts. It is about as safe as it gets and it stupid simple. 75:15:10 with Ti or Al burns fast enough that 2-3 increments will act as the bulkhead so you dont have to lift the dead weight and have it Jart back down when spent.

killforfood Posted January 30, 2011 Share Posted January 30, 2011 I just had the rear drums turned on the 1 ton last week and didn't even think to ask for the turnings. They cut heads, rotors, drums and blocks every day but Sunday. I'll for sure ask the next time I'm in there. Link to comment Share on other sites More sharing options...
pillyg Posted January 30, 2011 Author Share Posted January 30, 2011 I am probably going to buy FeTi. It is cheaper than plain Ti. Is there a difference in the sparks or will it work the same? Link to comment Share on other sites More sharing options...
BJV Posted January 30, 2011 Share Posted January 30, 2011 I am probably going to buy FeTi. It is cheaper than plain Ti. Is there a difference in the sparks or will it work the same? TI: bright white sparksFeTi: yellow-white sparks BJV Link to comment Share on other sites More sharing options...
