Not Ranked
David: 2 Very large taps, one to start the threads and a shorter (cut off with abrasive wheel) to finish the last of the threads without hitting the outside of the cylinders, or tap all the hole initially wiht the full length tap, then cut it off and continue enlarging each previously threaded hole. Then you only buy 1 tap.
