   Double, double toil and trouble;
   Fire burn, and caldron bubble…….

   I have used Aluminum (powder) and sulpher as a propellant…
   Is this actual (dry) powdered metal..?
   Is it mixed as a slurry?
   With what liquid ? and or binding agent
   What is the oxidant ?
   What is "AP"..?

   Are you heating this…? seems to be on a stool of some sort…

   Curiosity killed the cat…

   Powdered Metal.

   Mixed as a thyxotropic fluid.

   Binder is combination of Hydroxy Terminated Polybutadiene, Isodecyl Perlarganate.

   Oxidizer is Ammonium Perchlorate

   Stools prevents cooling of polyols premix prior to mixing.

   thanks. Toma is the mentor on all this. I’ll post more photos. The paint can mixers add some heat, so it becomes warm before pouring into the molds.

   Oh, and dave, the comment about the curious cat reminds me of my first trip out to Black Rock… (and a warning to anyone considering doing this)… I was reading the Apogee Components (makers of RockSim) book on rocketry. Page 131 reads:

   Making Rocket Motors
   “NO!!! NEVER!!! Do not attempt to make your own rocket motors! Many people have died during attempts to make their own rocket motors.”

   I burnt my hand once pretty good…(aged ? 15)
   Grinding the charcoal a bit finer…while already mixed with KNO2 and sulpher…
   That was memorable.

   Making motors is serious business. If you are interested, please contact Steve and get my contact information. DO NOT DO THIS ON YOUR OWN. YOU CAN GET KILLED IN THE MOST NASTY MANOR.
   You need to know what you are doing and need instruction. That is what we do at Mavericks.

   Meanwhile, enjoy the fruits of our labors….

   Does brass give the same amount of thrust?
