I bridged the gap with one of the trim rings (black). I like that look so much I added a second trim ring to the far end of a DF5 that was the main body. My defect was more than likely caused when either the thread milling bit was applied to the milled piece or it happened at the end of the thread cutting process as surface pressure of the bit was decreasing and caused the bit to walk a little. Not an issue for me though...
ROOT CAUSE Theories: It could have been a slight glitch/hickup in the CNC process that caused this? I would imagine that Tim has all his parts CNC profiles stored somewhere and just inserts a new profile when it time turn out a new batch of #whatevers.
Calebration on the of the tolerance specs. on the thread profile was scheduled but just had not taken place at time of turning your parts?
Slight defect in the material itself? ...
