Yep where I work its used to make drugs(man).I see a opp to make some money I have 2.5 litres under my desk ;).Back to the point I hope to file/grind/smooth down the weld and retap/coil this weekend(family allowing).Then repaint engine plates and dynamo and barrels and start to rebuild.

Don't paint your dynamo, this can lead to earthing problems.
The best way is to have it replated.

Hi Trev - my dyno is painted, no problems, do they in fact need to be earthed externally or at all ?

Well I have had the dynamo painted and plated and I don't rmember any problems.It was last plated ages ago when rebuilt and thats now rusty so painting(smoothrite) is the cheapest option.On another note redrilled and helicoiled and ballsed up.Template slipped inpatient me = needs filling again doh *sad2*

Ah - these thing do happen from time to time.
What's the plan now, assuming you don't have a spare inner case to hand to use as a template I think I would probably make one up out of thickish stuff I could bolt up to the crank with the other two holes
Good luck with it anyway

I have the spacer plate(steel), last time I just used two bolts and didnt do them up tight enough.This time four bolts and tight and select a bit just slightly smaller than the hole(last pilot was too small increasing the chance of error)
