    I mean a cheap rock tumbler with steel balls for the grinding and standard magnesium sparklers for ignition does would do the trick, I imagine

      In theory, lots of things work great. In practice…

      You generally want some kind of background and some proper equipment. I’ll concede that making thermite can easily go wrong in the opposite direction - cooking up a recipe that doesn’t ignite at all.
