By the way, it's a bit unkind to pick up a typo, perhaps, but this one is unfortunate to put it mildly. In the C-Beam machine write-up on the Ooznest web site, it says that " His video goes meretriciously through every step of the build". Pity this wasn't proof-read more carefully - "meretricious" according to the Oxford Dictionary of English means "Apparently attractive but having no real value". I'm sure that they meant "meticulously"...
That's the trouble with being educated Neale
