We decided to make the whole thing from one piece, so we
took a strip of 15 x 40 x 200 mm stainless to begin with, and
very roughly pre shaped it. Removing material now would make
it less unbalanced while machining the hole. Aad welded a piece
of pipe on just to be able to mount it in the lathe and the
Bridgeport easily, this piece will be remove later.
