So....having got the flywheel back from 'Govi Engineering' I set to with the angle grinder to remove the cooling fin stubs. Once ground flush with the main body of the flywheel I continued with a file, keeping the slight curvature to the outer edge. Then polishing with wet and dry.
It was at this point that my decision to keep the inner boss intact for refitment of the starting pulley obviously was a wrong one. Firstly I didn't need this option and secondly it certainly would look better without.
A trip back to 'Govi Engineering' for a second skim was the answer. Always happy to help 'Kev the Lathe' re-sculptured the centre, leaving a defining lip for esthetical interest. Now if that flywheel doesn't look like it came straight of a 1920's speedway Douglas I don't know what does !
It's not finished yet, more smoothing with wet and dry will be needed before plating but I'm sure you get the idea !
Well...time to lock up 'The Old Sidevalve Bar' fo't night and put t' kettle on.....
