Watchmaker's regulator update


On Sunday, six hours were spent behind the Schaublin turning the barrel. The end result: about half done. I needed the grooving insert and boring bar to continue further, and, quite frankly, after standing for six hours my legs were just killing me. Josh quickly placed an order for tools and on Thursday a small packet arrived from Sumitomo, Japan.
Sumitomo was founded in 1907 and today is one of the fine-tuned, multi-industry corporations which span from automotive to energy, electronics, semi-conductors to toolmaking.  The cutting tools division was founded in 1927 with the development of cement carbide inserts. To say that they know how to make an excellent cutter would be an understatement. As expected, the small parcel on the bench was every bit you would expect from the land of the rising sun: a piece of art itself.
There is no guesswork figuring out the cutting speed or misunderstanding the other important parameters. Each insert is individually bar coded and traceable - indicating that a tool like this is used to make components that will later fit into devices of the most importance - think of airplanes and submarines, satellites and super fast trains - where mistake is not an option. Certainly an overkill for a humble Australian handmade clock – but, to be perfectly honest, being exposed to perfection is not a bad thing.
One thing is certain - if you can't turn a 17th century clock part on a Swiss Schaublin using the most advanced Japanese cutter then you have no-one to blame but yourself.
