Step 17: Final Assembly
At last, we've reached the final assembly stage! By now you should have the frame as well as six main components:
Onto the escape wheel arbor, slide on the inner pallet arm.
OK, now for a bit of a tricky part. Still lying about on your workbench will be the five "clicks." These should be installed onto the five matching pegs on the escape wheel. They must be installed facing the right direction; refer to the diagram or the picture for reference. Basically, the points must engage the click wheel teeth when turned in a certain direction, but pass over the teeth in the other direction. Arrange the clicks in a vague circle, then lower the 10T gear assembly so the click wheel sits surrounded by the clicks. Then, slide the whole thing onto the escape wheel arbor.
Slide on the outer pallet arm.
Next is the bobbing arm. There is a long spare tube that goes on first, then the arm itself.
Last is the triskele and pulley assembly. Slide these onto their arbor.
At this point, it's a good idea to rotate and twist the various moving parts to make sure they pass cleanly over and under the other moving parts. I had an issue with the triskele coming in contact with the bobbing arm cap, so I raised the triskele about 1/4" off the frame.
Once everything seems to be moving smoothly, glue on the appropriate caps, being sure to allow no glue to squeeze out. For obvious reasons, the glue should not be allowed to touch any of the moving parts!
