So far, so good – although it’s a slow process. Getting to grips with a new boring tool and machine takes a while. The tools seem to be working well, I’m getting a lovely finish on the finest feed and the bore size corresponds to the graduation marks.
I’m starting to hate aluminium swarf though, it gets everywhere! I can only take a 25 thou cut, so opening the bore from half an inch to 80mm (3.149") is going to take a while. And when I’ve finished?
Start again on the real job, the conrod!!
