      Depending on the size of the part, I'd be tempted to go to a much larger
      file. Use the biggest one you can control handily and that doesn't
      totally overwhelm the part.

      If all you are doing is deburring, there are several trick tools that
      are really slick, often given away free as promotions by real machinist
      supply places.

      An example:

      If you have a lot of plates you can also tumble them. This may give you
      a nice finish as well depending on what you want.

      If you are using a bench grinder for deburring, get a giant Cratex
      wheel, standard wheels will still leave a rough edge.

      I'm not sure if you have a workshop area, but a heavy vise on a sturdy
      bench help makes quick work of many aspects of armoring and almost any
      miscellaneous projects. In addition to sawing, filing and chisel metals
      and the like, I also use mine for is cutting up and roughing out
      soapstone for seals!
