Black powder rocket question right here?

why do people say to grind black powder to make rockets. Isn't it suppose to be powder already. or what?Black powder rocket question right here?
Most rocket fuel for models is in solid form but made of black powder. When it is in the state of a wet sludge, it is compressed into the engine tube, and clay or ceramic nozzle is poured on top. When it is dried it is a solid fuel.





Way back when, they likely did use powder but black powder is very flammable and actually explodes and doesn't burn like modern propellants.





I wouldn't try grinding or smashing up powder. Black powder is sensitive to compression and can explode. Happens during manufacture process in the plants that make it. That's why they make it wet first , dry it in sheet form and granulate after. Roll caps for toy pistols explode because they are compressed minute amounts of very fine black powder. I would just buy the engines and not try making them. Too dangerous.Black powder rocket question right here?
I don't think you'll listen if I tell you to 'stop before you hurt yourself'.


I didn't when I did that as a kid, so lets try to keep you in one piece:


1.Don't even think about trying to grind black powder.


(Even the pro's in industry have accidents doing this and allow for them.)


The charge of a solid fuel rocket must be formed into a single slow


burning grain, or you get a bomb, not a rocket.


To form %26amp; pack your charge, get wood alcohol or another dry, (waterless),


non-polar solvent. Make a thick paste with your powder.


Form that into your charge, and dry it well..


Inspect the charge carefully.


If there are voids or cracks, it's dangerous.


Start over.


Use a long fuse or electric ignition and be well back, and behind


something solid when it goes off.


If you HAVE to watch, use a mirror.
The finer the powder the faster it will burn.
because they just do
