Does the wife have a vitamix or maybe an old blender afterwards you could use some screen wire to size/grade the resulting dust. Any leftovers can still be burnt as fuel. Cost is not the only reason for doing something. There is a lot to be said for knowlege gained by trying new things. I myself am working on a wet tumbler with the intention of using steel BB's as tumbling media. May or may not work but no harm in trying. So go for it dont let the naysayers get you down.
