Machining Shaft Dogs

One of the little tasks I had pending was to clean up the bolt seats on the tail rotor drive shaft dogs. 

Because of the curved taper from the shaft collar to the dog face, the washer/bolt interferes with the curve.


I could have filed an angle on the washers, but that seemed a little inelegant, and I DO have this wonderful mill.


Like all the machining I have done, clamping aligning and measuring is 90% of the time and the actual metal cutting  takes about 12 seconds.

I was careful to not take off very much.  This is a jumbo-thick part, so I am sure it is plenty strong, but I still did not want to cut full width flats as that would have eaten quite a bit more metal.
