sorry, Nigel, I should have worded my Question better. The Question is “is there a running Thread discussing G.Martyn’s 0-6-0 Construction Series ?”. I have gone back quite a few Pages in the “Locomotives” section but have not found any Posts regarding Gerald’s Design.
I am curious how Gerald seats the Balls in Check Valves. Gerald does not show the typical D-Bit flat Face. Is he using Nitrile Balls ?
