Finally managed to machine the support plate for the cylinder liner to the right size. The lathe wasn’t able to do it, so I used the Whatton boring machine. Unfortunately, the Whatton really struggled with the work hardened laser cut plate, and the tooltips got hammered, but finally it was done.

The cylinder liner can now be held in situ, whilst it’s being rebored.





Everything is almost working OK, but I need to refine the belt tension, and the tooltip selection. I think I need to convert the Whatton to indexable tooling, as well as look at the pulley & V belt some more, as the tooltip can stall in the bore with a heavier cut.
