The cylinders on No 9 needed boring as they had become worn after many years of hard work. There was a score line in the RH one which required skimming. N.L. Engineering Ltd came up from Wigan to do the job. They completed the work over 3 days between the 3rd & 5th December. The boring machine is an amazing piece of kit and John and Jake have done an excellent job. The cylinders are as smooth as.........! There are some videos in that section of the Blog for you to enjoy. Apologies for the length of this Blog but it is a very important part of No 9's restoration. Most of the photos credit Jake Morrow.
To start the covers on the rear of the block had to be removed. The nuts looked as if they were going to give trouble but after heat was applied to each a sharp tap from a hammer released them!
