  1. Isn't CuO one of the most energetic thermites?
  2. Thermite has to be one of the most forgiving formulas there is. When I was a kid back in the sixties, we made thermite by wire brushing rust off of everything we could find in the garage (we had to anyway as part of our chores), then we filed down aluminium drink cans until we got enough. We used a home made balance to get the weight proportions right and aquired some chemicals and magnesium ribbon to light it. We mixed it by shaking it in a small paper bag and ended up with a pile about 2 times the size of a fist. It worked like a charm. It melted through two 25mm steal plate and a little bit into the ground and left a slug of iron behind. Phil Blackwolf
  3. I have seen 2 industrial drums that were removed for maintenance. One was about 50cm in diameter and had files mounted parallel with it's axis around the entire drum and the other was about 25cm in diameter and was in effect a rotary file engraved 45 degrees to it's axix. In both cases they had steel wire brushes mounted on the bottom to keep them cleaned. I can't remeber if they used water or something else, but when they processed the aluminium powder the would first run it past magnets to pick up any chips or wire brush bristles that had broken off, and then seived it for sizes.
  4. For your shield, I would recommend you use polycarbonate (lexan) instead of plexiglass, it stands up much better and doesn't tend to shatter at all. Phil Blackwolf
