Marlin07 Posted February 8, 2013 Posted February 8, 2013 Hi Guys, Due to our wonderful regulations here in Canada obtaining Potasssium Nitrate can be difficult. I have a supplier that is getting some but it won't be until spring. My question is can commercial (IE. GEOX) powders be used for making rammed BP rockets? I want to do a little experimenting before the spring and get some tooling but I am unsure if commercial BP is to granulated to hard to ram into a solid fuel. Rockets are my main interest for the simple reason you can't purchase them here. I have my display supervisor card and have access to 1.3g items but rockets are not available anywhere here. The closest we have is small girindolas but they are rare. Thanks!
nater Posted February 9, 2013 Posted February 9, 2013 If you can get fuse powder or meal-d, you will be okay. Many people make rockets with fuse powder and meal-d will most likely need to be slowed down with additional charcoal to prevent a CATO.(or leave the nozzle out) . If I was in your situation, I would try to get fuse powder and standard BP tooling. Here in the US, it is $1 / lb. Sporting and coarser grain powders will not work rammed. The grains are hard enough it takes way more pressure then you can ram with a mallet to consolidate into a solid fuel grain.
Marlin07 Posted February 9, 2013 Author Posted February 9, 2013 Thanks Nater, I figured commercial powder would be too hard. A dollar a lb hey? That is unreal. I'm gonna check with the guys who supply display fireworks and see if they can round up some meal-d for me.
