Q: Two of the items* are identical (material composition is slightly different).
One of them was bought last week and the other two are at least 20 years old.
Can you guess which one is which?
The suspense is mounting! Do send your answer to: nfo AT resurface.se and you will get a reply/A: (bonus if you can name the number of the item from the schematic).
But what about: “Failure by design”? Well, look at the picture. Could it be a matter of choice of material, possibly? The only failed part out 19 precision tooled parts and a ball bearing at that?
There are a lot of very talented people working/doing just that (one is to many).
Please see: Theory/Practice, The Mechanic** and Failure.
* They’re ball bearings and they make things run smoothly when properly lubricated, balanced and made of the right material. They can last for an eternity or not… if they’re designed to fail. Ensemble will be re-assembled. As promised.
** And by pure coincidence it happens to be the title of an Anthony Rother track that I really like not (that are any that I don’t like, but for the sake of the argument). And I can assure that it pure coincidence.
