Steve is still assessing the cylinder bores. To check them for straightness and roundness, he made up a stop for his dial gauge which he bolted on so that the gauge fits across the bores. He also made a handle so that it can be held at any position along their length. He then inspected the bores in the better of the two blocks to see whether we can get away without lining them. He found that both are barrelled in shape with one being 0.020" bigger in the middle than the ends and the other 0.018" so, unfortunately, both will need reboring and then lining. At least this removes the need to decide whether or not to line two or four cylinders!
This weekend, we are going to seal and pressure test the water jackets to see if there are any more cracks. If no more are found, we will get the blocks stitched and then start looking for someone with the capacity to bore them out by 0.030".
