Re: SpAriel MkII aka The Hermanator

Lovely frame jig Vincent. Did you already have it or did you made it specially for this job?

Re: My 4G Restoration Blog

Its looking good Paul - nice work. Whilst you are at this stage, can you glance at the front timing side bush and tell me whether the drain hole is present which runs down at 45 degrees back into the crankcase from the outside of the bush please? The engine I am working on has this drilling but my ...

Re: My 4G Restoration Blog

So where did you pick up your PA speedo restoration skills Paul? Self taught? Progress is slow and steady on the 4G engine, but as I succeeded in assembling the crankcases today, and put the coupling gears on, I feel the worst is behind me...it will be all down hill from now on...not literally I hop...

Re: My 4G Restoration Blog

Nice to see those photos Paul...and that adjustable reamer looks like a good quality one rather than the rather poorly made Indian ones... Is that a domed nut on the top of the timing chest? Is that instead of the rivet for the fibre rubbing strip? Just about to replace my strip, so quite interested...

Re: My 4G Restoration Blog

That's quite similar to the later Mk11 with duplex chain. Looks fine. The later is longer. Have you checked that the chain has a 'ramp' introduction to the tensioner rather than a step? Certainly looks as though it has. Thanks Roger. Yes, there is a slight ramp at the start. I thing I might extent ...

Re: My 4G Restoration Blog

Hello Paul, I like your idea of a line reamer tool. What clearance do you intend to use between your timing side bushes of leaded bronze and the crankshafts' journals? And how would you measure it? Bore gauge? Internal micrometer? I understand that the 1.5 thou used with Babbitt material may not be...
