Rolls Royce (who examined the DB engine) cautioned the restorers of the "Black Six" not to bend the crank because they doubted very much their own ability to fabricate another one that was as "true".
Actually they probably do or can find a way to either copy or replicate the item with modern methods and materials, but for a company like RR it would take deep pockets to motivate management to find personnel to do such work. In reality, I'd bet dollars to donuts you can find machinists is some obscure location that could produce a DB crankshaft providing correct engineering data as well raw forgings are provided.but in 2010 they build gas turbines and nuclear reactors they dont have the skills or machinery to work on a piston engine.
I heard this a few years ago, and I always thougth that it was said during the WWII, when british tecnicians was examining a captured ME109 (and the english machinery was not able to reach the german tolerances). I realised now that they actually can´t make one of those cranckshafts!.Rolls Royce (who examined the DB engine) cautioned the restorers of the "Black Six" not to bend the crank because they doubted very much their own ability to fabricate another one that was as "true".
100% spot on - the German tended to over engineer a lot of things for no reason in areas that also made no difference in the performance of the final product. In many cases this was their logisitcal undoing.What would the benefit be of DB making a crankshaft that was so finely made. Surely it would be better to make a crankshaft that did the job but didnt require watchmakers style tolerances.
