Hi
Well today I tried a trial fitting of the gib key . I fitted the flywheel . The key ways in the crankshaft are not very smooth , they must have been machined with a blunt milling cutter , so I used a thin diamond file and emery cloth and some lapping compound to smooth things out . I also smoothed out the gib key surfaces and lapped the gib key into the keyway . I have been using blue marker pens on the gib key as a guide , like blueing on bearings , but I cannot get a good tight fit for some reason . I think something is not flat or the faces are angled ?
I will see how I go tomorrow
