The source of the Father-Son disagreement was NOT concerning cylinder angles. W.E. Brough had become an advocate of the flat twin, producing his own engines totally in house ( which he had done with all the earlier productions) , capacities of 496cc to 810cc. The reason that the break between the two men occurred was COST . It was post WW1 and father William was short of funds, He had been attempting to raise capital by selling redundant factory stock,complete engines, bits of engine frames ,even a Brough car. Adverts had been regularly posted in the press. Independently son George had been going out on a limb with his own sports development of the 500cc Brough flat twin engine.. | The source of the Father-Son disagreement was NOT concerning cylinder angles.

It would have the engine carried in a detachable duplex cradle, so it could easily be removed. The frame lugs tapering down to the tubes, with a toolbox astride the top frame tube. The 500cc OHV engine was a new type that had already been made and undergone bench testing. The crankshaft ran on roller bearings with its mainshafts and wide roller big ends drilled for heat treatment.Two camshafts instead of the single previous one.Figures on test were 14 bhp at 4200 rpm and 13.2 bhp at 5600 rpm.The press were duly astonished at the high engine rpm attained.George said he was prepared to stand by the design to the tune of £100. | |||
When George wanted to put his new Brough engine into production the cost was more than his father would contemplate. Father & son relationship could be mercurial to say the least,Best friends one minute, daggers drawn the next. | |||
William Edward Brough was actually a rather Superior engineer, much better than his son George. | William Edward Brough was actually a rather Superior engineer, much better than his son George. | ||
