Thanks Irving... Haven't seen hobnobs on here since that little spat a couple of weeks ago, which is sad as I really enjoyed his sense of humour... and benefitted from his contributions.

I will make use of a machining service that has access to a lathe and CNC, as that tooling looks expensive for now... Is a boring head and a fly-cutter one and the same thing?
