Guys, I am intrigued by the amount of experts you all are mentioning, some good others not so, Myfordboy, all i can say is the following, My old foreman moulder would have been last seen chasing him through Glasgow south ,into Glasgow Central and then Glasgow east holding a long rammer to shove up his posterior, He did not suffer fools gladly! Many years ago approx the mid to late 1950 era my hero whose writings put me very much on sound tracks was a prolific writer in The Model Engineer namely Edgar T Westbury, At this present time I am working on one of his designs The Unicorn Engine, He also did a series on The Model Engineer Beam Engine, His methodology was at the time geared around a period in British history when the average model engineer did not have a lot of spare cash
Edgar T WEstbury was actually Warrent Officer Edgar T Westbury ex Royal Navy , an engine room artificer 1st. class , who rose from the position of a stoker to officer grade , By all accounts he rose from very humble beginnings, He was a wizard with small internal combustion engine design, He also designed a small steam plant for charging batteries for radio transmission behind enemy lines in the jungle in the 1939-46 era they were silent , and the whole caboodle could be packed inside its boiler , the size of a pressure cooker and would be carried by a paratrooper during parashute drops. -- An all time great!
