Edgar T Westbury

Perhaps best known for his model engine designs and contributions to Model Engineer. He was born in 1896 and served in the Royal Navy during the latter part of the First World War. In the late 1920′s he was an instructur in the RAF. During World War Two he developed a number of small petrol engines for use by the armed forces. Edgar T Westbury died on 3 May 1970.

Below is a list of the models and publications:

Loyal

Single cylinder, spark ignition, air cooled, 2-stroke, design released in 1966. 1-3/4″ bore and 4″ stroke giving a capacity of 3.06 cuin.

The model shown here was made by Mick Cherry and we have an article all about his hunt online for data about the Loyal 2-stroke and the issues he had with getting it to run: There were some diagrams but the best thing was a timing disc, and it was from this that I built the engine. It is dead simple, with the inlet valve being sucked open and the exhaust valve being blown open.
