Redesign of Strike fly fans

Brass 3 train (28).JPG (551422 bytes) The first three photos show the strike fly fans in original condition. They are so crudely made it is difficult to believe that they were made by the original clock maker. Note the empty hole on the right in this shot as well as the left side in the next. look at very crude attempts at the creation of a friction clutch to slow the fan in both shots.

It's possible that after the holes were drilled it was realized that the fly fans were too close to the gravity escapement fly clutch. Notice that the empty holes would have brought them inward; toward the central escapement clutch causing them to clash. Putting the fly on the outer 'ear' of the frame opposite from their current locations was not possible with the original hammer configuration as the hammer arms would have struck the flies. In the end, the hammer arms were radically reconfigured and the flies could have been moved to that location. In retrospect this is one of the few items, if I had the chance, would redo on this project.
