Not kidding. My son's teacher asked me to make 1 cup of iron filings for
the 4th grade class magnetism experiments. Sounds like a real mess. I was
thinking of put some sheetmetal screens on the milling table to catch the
filings and using a roughing endmill on really fine feed to grind up a round
bar of cast iron I have.

Any better ideas on a cutter or method would be appreciated.

Thanks,

Well, I hope u blokes had fun with this. Next time ask a granny. Although it is much too late may I say: In South Africa we buy 50g of iron filings for less than a dollar from a business called Experilab.
