The suggestion to take the corners, edges from plastic is sound practice for new people but should be done in a repeatable and safe way its like riding a motor bike no need for trainer wheels but not to be aware can be fatal. Even the most experienced pilot goes through cockpit drill before departure. Let those who teach turning give their impressions. People in TAFE ,School environments must practice safer methods. Over here any Tom Dick or Harry can use a lathe they instal themselves without no volt switching etc that are mandatory in a work situation. Like fitting stoves, lights, power points, three pin plus, sockets, earth leakage protection proper earthing there is a best practice.
Yea I know Heath Robinson is alive in so many places just does not make it safe and right. Trust none of us encourage unsafe practices.
