    Not in 1954, no! The major bending force occurs at about the centre of the slide bar due to the offset thrust on to the crank pin. There is no offset at each end of the stroke as the thrust is in a straight line. In forward motion the thrust is...

    Designers seemed unable to decide on this. Stanier's Lizzies had a support at the back but the Coronations had it quite a bit further forward. Both had supports on the back cylinder cover though. I'm skeptical about the heat transfer and...
