Take it easy on me Merlyn...I'm still working on the first question. An OMO packet in the window ? What can it mean. ? Could it be an uppity
Mrs. Bucket (Its BOO-KAY dear ! ) type of woman who wants it known that she uses OMO an not any of those inferior products such as Rinso,
Persil ,Fab,Tide, Surf or Lux. Or is she giving a signal to say "I'm 'On My Own' an feeling lonely". Thats the best i can do on the OMO question (Do I get any marks ?) ... now for the serious L/H v R/H Q. I'm poring over W.A.J. Chapman's "Workshop Technology Part 3"
Have actually read more of it in past few days than in the 50 years since bought. 660 pages...no mention of C.T. H. I had 'C' for 'clockwise'..
but you say 'Cranking' . Chapman makes reference to Frederick Winslow Taylor's classic ' The Art of Cutting Metals". So read his book ...
published in 1906 ( You said pre CNC ! ). Not a mention of C.T.H. The American Taylor was very brilliant. He conducted ~40,000 metal cutting experiments. But he was also arrogant and elitist. He stated before a congressional committee -- :
" I can say without the slightest hesitation that the science of handling pig-iron is so great that the man who is physically
able to handle pig-iron and is sufficiently phlegmatic and stupid to choose this for his occupation is rarely able to comprehend
the science of handling pig-iron "
He was the founder of Scientific Management...which was to make workers work like robots 100 years before the idea of replacing
workers with robots. Anyhow...still dont think i'm closer to cracking the code...all over the place...Ernst & Merchant Theory, Ackworthie,
Victor P Astakhov, Shamoto, Bishop & Mcdowell , Lee & Shafer , Hencky Equations Theorem ,Dewhurst...an a dozen others.
You say dig out the old ref. books....which one is it in ?
