-- I was missing the square nut.
-- The instructions could use some improvement. Not all the finished sub-groups were labeled with their "L" identifier and that lead to some mystery solving.
-- The instruction identified two spacer tools: T5 and P19. The implication is that the T5 tool is on a plywood sheet near the T4 tool and therefore as thick as the plywood. Not so. Both T5 and P19 are clear plastic spacer tools. The clear plastic wasn't obvious without emptying the bag containing the axles.
-- The pendulum warped after it was popped out of the plywood. It hangs up on the frame.
-- It works but slows down and stops after about ten seconds. No gears are binding. The escapement seems to drag and waxing or un-waxing doesn't change the operating time.
-- The clock hands don't stay positioned. They freely rotate. The yellow spacers just don't pinch hard enough.
-- Piece A10 (Hour face) falls off.
Work arounds:
-- I substituted a spare piece of the scrap plywood for the square nut. I drilled a small hole for the adjustment knob and it worked fine.
-- The sand paper works nice on a curved surface but for the flat surfaces I used an emery board.
-- I used both the provided was and a birthday candle.
-- I removed the pendulum, flipped it, and reinstalled it. Now it clears all other surfaces. If you have to do this then be careful with the orientation of the escapement.
-- The clock hands don't get pinched hard enough so I put a small piece of plastic wrap in the hole to bind the post.
-- I hold the hour face in place the same way.
The clock is accurate. But the downside is that the wind up only lasts about 3 hours. So unfortunately you really can't use this as a clock. But it is a unique piece.
He claimed the assembly was painstaking (which is significant coming from him), but if you follow the directions very closely, and don't rush, and give it lots of time, then the result is satisfying. The only problem (4 stars instead of 5) is the assembled clockwork became slightly warped, and he had to re-align it and hold it in place with a rubber band.
High recommended for someone who has the time, patience, and attention to detail.
While having the flame near the gear I kept it rapidly moving around so it wouldn't stay on any one section too long and possibly cause it to light on fire or melt any of the yellow plastic stops on the metal axles. One nice side benefit of this is if you do it enough you can give the edges a cool charred look. Again, use common sense and don't burn your new clock.

The clock started and ran immediately. A pleasing click during winding of the spring with the key, and a pleasing tick tock sound when running. Good for about 3 hours of run time and it keeps time at the neutral setting of the pendulum weight. Plus it looks impressive.
Perhaps a little darker print on the hands and the numbers would help if one was actually interested in using this to keep time, but this is trivial.
