justvisiting Posted May 3, 2020 Share Posted May 3, 2020 A 1lb rocket tube is just over 3/4" ID. A 3lb tube is just over 1" ID. For BP rockets, a 1lb tube is 7-7 1/2" long, and a 3lb tube is 10-10 1/2" long. A 1lb black powder rocket uses about 80 grams, and a 3lb black powder rocket uses about 225 grams. These amounts vary, depending on moisture level rocket type, charcoal type, pressing or ramming force, delay length, etc... Link to comment Share on other sites More sharing options...

justvisiting Posted May 3, 2020 Share Posted May 3, 2020 Lots of folks come here from non-english speaking countries. If you make a good effort to type english, people make a good effort to help you. I am sure there are others here that know your language too, whatever it is. I only speak english. Link to comment Share on other sites More sharing options...
