The largest workable mill engine in the UK is this twin tandem compound of about 2500 horsepower. The flywheel ran at 58 rpm in use and was doing about 52 rpm when I took this. The flywheel is blurred in this shot as it was running. The crosshead appears stationary as the shot was timed close to back dead centre. The little brass wheel is the indicator drive for taking indicator diagrams to calculate the engine's horsepower.
