Thanks for that super quick reply, yes noted where shims were placed, gaps are 1 .007 2 .009 3 .005? 4 .005? 5 .011 6 .005? 7 .005? 8 .005?, as you can see its 3,4,6,7,8, that are the problem, took your advise and just checked them 3,4,7, will rotate easily, and 6,8, will not, so following on from here i will treat 6, and 8 as having no gap at all, and 3,4,7 as having a estimated gap of .003 ( got to start somewhere), been using your spread sheet to do the calculations, really good bit of kit.
Many thanks Steve.
