    Now a little side note about that errant hammer lever. Assembly for me went very smooth as wheels seemed to almost seek their holes and plate dropped nicely with smooth motion of wheels when I sat back, pleased, I noticed a leftover part;
    This is when I was glad I took the second picture. I just wasn't absolutely sure exactly how to position it.
    Satisfied I understood placement I commenced assembly again. This time not so smooth. Uh-oh. What's wrong? This time the plates refused to close. I studied the problem area and found it quickly. Make CERTAIN hook on lever arbor is seated between tension spring and seating cushion. Mine was resting on top of the spring.
    Looking GREAT now. This' beginning to be fun!

    O.K. Let's wrap it up. All strike parts installed, crutch still off, let's install the motion works. First push minute cannon onto centershaft - anywhere - any position - doesn't matter. Next by setting timeside in motion note that every revolution minute cannon advances starwheel. O.K. this time rotate it again slowly, allowing starwheel to be advanced and soon as it is advanced - STOP movement. Now install intermediate wheel with the two pins such that the HOUR pin is a few degrees in front of the strike flirt lift lever. This placement ensures that the hour will be advanced a few minutes before the hour is struck. We wouldn't want them to occur simultaneously for two reasons. 1. Two simultaneous loads may be excessive and stop the clock and 2. We don't want to risk the advance being incomplete at time of strike.
    Now it may work just fine if not set up this way but I would not guarantee it and you would not want it any other way.
    Install the hands. Simple. Advance to hour and strike. Count the hammer lifts. Three? Install the hour hand to III and the minute hand to XII. Stick the crutch back on and commence final tests of strike and time.
    Questions? Corrections? Additions?

    Shoulda warned ya; No volunteer; I'll do it. Now BONG I need you to keep me honest - your questions if I miss something - your corrections if something doesn't seem right. You're welcome to photo shop it if you prefer.
    Really not much to it. We'll start with the WARNING phase.
    Warning commences when the pin on the intermediate wheel begins lifting the arm on the strike flirt (middle picture). At that point the rack hook is lifted from the rack. The rack falls onto the snail on hour strike and the gathering pallet rotates a few degrees before being stopped by the warning pin on the fourth wheel. (bottom picture) The pin on the fourth wheel is arrested by an extension of the strike flirt that protrudes thru the small slot in the plate.(top picture)

    STRIKE:
    Intermediate wheel continues to lift the strike flirt further until it falls off pin of intermediate wheel releasing the warning pin. Strike flirt then drops to rest and striking commences.

    Pins on the second wheel provide for hammer lift.

    Gathering pallet powered by the arbor on the third wheel moves rack one tooth for each strike (progressing toward the butt of the rack, rather than the tip) until strike number is complete. At that point, rack hook now falls into end of rack and gathering pallet is arrested by landing on the pin sticking out from the rack also.

    Nearly as I can see that's about all there is
    Corrections, questions, additions welcome.
