[QUOTE="moonbase, post: 1112257, member: 178786"] Today's offering is from phase 1 of the general tidy and clean up for the dish that is not in storage. Prior to cleaning I removed the mounting ring fixings and cleaned out the three x M16 boss head bolt holes used to mount the dish. For cleaning the dish face, the mounting fixings were replaced with 6" long M16 bolts to prevent the central curvature of the dish bottoming out on the ground. The dish curvature in the centre protrudes beyond the plane of the 1200mm mounting ring so it cannot be rested on the rear mounting ring with the face upwards. After cleaning I did a string test on the dish using 1.0mm thick nylon cord. There was a very marginal gap but it was less than the cord diameter of 1.0mm. Considering the age of the dish and its size, I am happy enough with the string test. I need to clean the dish face a little more once it is on the mount or better angled for access to the centre It was not possible to reach the central part easily to remove some of the algae marks. Also, I am not decided on the S4C logo, I could either leave it in place to show the provenance of the dish or I could remove it. Pictures attached below. .
