WV-Pyro Posted July 8, 2006 Posted July 8, 2006 I am planning to start making some rockets of my own instead of buying Estes engines for my payloads. I was curious as to what tooling I should get and for what size rocket. I don't plan on sending up anything weighing over 200g, but I will also send up some payloads as small as 30g. Since I don't have the money to buy more than one rocket tooling set, I was wondering if someone could recommend what kind of tooling, and for what size rocket I should get; as mentioned earlier. Anyhelp would be appreciated. Also, could someone recommend the ratios I use for the type of tooling. I already have 1 pound of what I believe is airfloat, but I am not sure as I got it free from school. Using it in 75:15:10, it blows out the nozzel in my 3/4" ID x 3 1/2 " with a 11/64" nozzel and half core if that gives you anytype of idea if it is airfloat. Again, any help would be appreciated. Thanks
ActionTekJackson Posted July 8, 2006 Posted July 8, 2006 First off, there's plenty already posted to read about this. doubt it warrented a new thread, but I'm no mod. I'd suggest searching for specific Rocket Compositions, and Nozzle Ratios. All of which can be found in the existing Rocket Threads. P.S. Goodle does wonders!
WV-Pyro Posted July 8, 2006 Author Posted July 8, 2006 Yes, Google does do wonders, as I have used it many times. I was just curious what size rocket would be best for payloads from 30g to 200g, and what tooling would be best for it. I have done alot of reading, but most of the engines that can take up 200g payloads or too powerfull for 30g payloads as they take them too high, so I was just asking for a happy medium. I am sorry if this didn't warrent a new thread. A mod can delete it or move it to the appropriate area if they feel the same. I was just looking for an answer as fast as possible. Sorry, if in some way, I offended you by creating a new thread.
ActionTekJackson Posted July 8, 2006 Posted July 8, 2006 Not a huge deal bro, it was a legitimate question. Just tryin to help ya out with keepin things smooth here. No one's flamin ya. Here's a .doc file with most of the info you're lookin for.Payload - rocket size list Just as a reference a 1lb rocket is usually a 3/4" ID x 7 1/2" length, or so the info I found explained.
moonshot Posted September 8, 2006 Posted September 8, 2006 Here are some shots of tooling that I made from 3/8" brass round stock. I turned these on a lathe. Sorry the pics are a bit fuzzy. I fogot to put my camera in close up mode but you should be able to read the sizes off the ruler. The taper is 3mm at the base so that will be the nozzle ID. I only taper the spindle slightly to make it easier to remove from the core. The shorter spindle is for a 2" long case with 3/8" ID. The longer one is for a 4" case with 3/8" ID. http://i107.photobucket.com/albums/m314/di...07/S3010729.jpghttp://i107.photobucket.com/albums/m314/di...07/S3010737.jpghttp://i107.photobucket.com/albums/m314/di...07/S3010735.jpg The smaller rocket will lift 30 grams 100 to 150 feet. The 4" rocket will lift 50 to 60 grams 250 to 300 feet. http://i107.photobucket.com/albums/m314/di...07/S3010699.jpghttp://i107.photobucket.com/albums/m314/di...07/S3010692.jpg I posted a tutorial on making headings for these rockets so check that out they are specificaly designed for these rockets. Heres a pic of my 4" tubehttp://i107.photobucket.com/albums/m314/di...07/S3010726.jpg I will post other tutorials on rolling the tubes and making tooling as well as the type of propellent I use. anyway I hope this help give you some good ideas.

Thanks Slow your propellent down a bit. I go with 71 KNO3 24 charcoal and 5 sulfur. Mill it in a tumbler overnight and granulate it with dextrin as per the directions at United Nuclear. I was blowing up tubes with my 75/15/10 and went to the 71/24/5 and don't have a problem now. It also adds a nice orange tail to the rocket.
