    Right on, and

    use a hand drill or a power drill that is barely turning. This is where a steady hand is most important and speed truly destroys.

    couldn't agree more

    sharp bit and tap, and drill slow. Good cast iron is soft and drills and taps easily. I have done it many times over the years. I usually use pro-poxy on the threads or Xpando just to be on the safe side
