I love the reference to Fluidyne Red and Black, it reminds me of my short
RNZAF career as the aircraft spray painting aspect of my trade. Aircraft
colours were specified with names such as "Royal Blue", "Dark Admiralty
Grey", or Light Admiralty Grey".

There is an idea forming in my mind of a quick method for cutting smaller
stems that will be quick and efficient. It involves a sabre saw and
hopefully I will get one together soon as I have a TLUD design I am also
pondering on.
