The photo shows the current state of the two sets of valve gear - swing links and combination levers bored out and roller bearings pressed in, holes tapped and then the whole lot painted. I have also made 18 (yes, 18) motion pins to fit the lot together. The central core is silver steel, with an M8 thread at the end. They also have a 3mm hole drilled into them, with a grease nipple screwed into the end, and a hole opened out so that lubrication can get into the bearings.
