Cylinder blocks Part 2 - Boring
Boring a cylinder in the 4 jaw. It was tough to get it aligned in the 4 jaw. To get the alignment, the cylinder was centred on a die holder which was set in the headstock taper to ensure that the bore was machined parallel. The bolting flange was also clocked with a DTI to ensure it was parallel.
Boring the 2nd cylinder The piston rod end was machined on the lathe to be perpendicular to the bore, and then the other end milled flat for the covers.
