After making a solenoid motor in a couple of afternoons in the workshop I thought I should go for something rather more sophisticated.
The frame of the engine was made from a homemade plywood, giving a lovely contrast in wood colours along the edge of the frame.
Each cylinder fits to one of these plywood frames and the crank boss goes through the 2 frames at the bottom, this allowed me to stagger the frames and so give the necessary offset for each cylinder centre, needed for a single pin big end.
The crank is nearly at bottom dead centre and so both pistons for the solenoids are out of the bottom of the coils.
This image nicely shows the frame in which the engine is mounted. This is a boat shaped frame, designed to represent the lower part of a bike frame.
The video shows the engine at an earlier stage when it was mounted in a rough working frame – I use this type of frame a lot as it allows me to work on the engine in the workshop and not worry if I damage it.
The power to the engine is provided by 4mm banana plugs and the engine needs a good 12V 2.5A power supply to run well.
I must update the plastic covered brown and blue cables with some cloth covered ones as they will add to the look – this motor is all about looks…
