RC crank and drive

The Flywheel and cylinder block are all Meccano except for the valve bonnets and blocks which are machined items as nothing even closely resembles them in Meccano. All the valve and governor rods, linkages and collars are specially made for the engine. They are Ø 3/32" with 8 B.A. fixings for which I make no excuse and some are based on Mecarep Micro system parts.
