Today saw the completion of the turning part of making the cylinder liners. I must admit to being a little surprised at the level of consistency I achieved in making the liners. The long layoff  seems to have had the benefit of increased efficiency! Long may it last but I suspect normal service will resume as soon as possible.
The only job left to do with the liners is to hone 7 of them then fit them to the castings. Edgar T Westbury in his article published 63 years ago, suggest pressing them home by use of the tailstock against a faceplate so I will leave off pressing them home until I have turned the 16 valve liners since they to have to be pressed home before all are cleaned up and the head brought to size.
I am considering using varnish as a lubricant/sealer for the cylinder liners as suggested in Edgar's article. I have yet to decide.............. Latest picture....
