CON RODS FOR TRIPLE
There are three connecting rods, and despite the different cylinder sizes, the 3 rods are identical. Due to the fact that the stroke for each cylinder is identical. It is only the bore which differs.
The castings for the con rods did not permit them to be held in a lathe chuck, even an independant 4 jaw. So I drilled centres, and held them between centres for turning the shafts.
