carouselbottom.jpg
Bottow view of the carousel with the Spybot and drivetrain removed.

carouselbottomclose1.jpg
Close up of the underside of the lift mechanism. 
Notice just below the center of the image where a black axle protrudes into the tyre. This is a 2-stud-length axle cut down to 1.5 studs to make room for the wide Tyre. Normally this axle would be flush with the technic brick, but it has worked loose in this image.
Also visible is the method of attaching the wing plates to the rectangular plates using 2 x 2 corner plates (or bricks) at the only point where the studs line up.

Another angle of the same mechanism.

carouselbottomclose3.jpg
Another lift mechanism. Notice that the black technic beam is offset 1/2 stud into the white beam above it in order to get the proper spacing of the liftarm through the slot in the deck.

carouselbottomclose4.jpg
Another view of the previous mechanism. The liftarm in this case is a 3-stud-length axle with stud on the end. That stud is snapped into a yellow plate above the deck, which is the base of one of the carousel animals.

carouseldeck1.jpg
Carousel with the Spybot, drivetrain and "rotater" removed. You can see how I approximated a circle. You can also see how my collection is color-deficient.

Close up of the plate arrangement of the deck.

Carousel deck from the bottom.

carouseldeckcheat.jpg
Here is where I cheated to complete the circle.

carousellifter1.jpg
Lift mechanism above deck with dragon attached. The liftarm is constrained to vertical-only motion by let it slide along the roof supports.

carousellifter2.jpg
The same lift mechanism from the other side and with the dragon removed. Through the hole in the deck you can see the top of the 24-tooth gear which was fully visible in the views from the bottom.

carouselrocker1.jpg
This liftarm rocks back and forth as well as up and down. It's motion is constrained by the plates around the slot in the deck. The old 2 x 8 white plate is from my mother's Lego collection. I wonder how it got in my collection?

carouselrocker2.jpg
Same rocker with duck removed.

carouselspokes1.jpg
The "rotator". The spybot drive train rotates the central axle. The ends of the spokes are connected to eight of the roof supports.

expandaxles1.jpg
Reinforced axle which attached the drive train to the "rotator", shown expanded. Wedge wheels (pulleys) and friction pins were used to reinforce the central axle. One side benefit of this arrangement is that the pulleys can be stretched apard or compressed together without taking anything apart. This made is easy to adapt the spybot height to the height of the carousel.

spybotrain2.jpg
The Spybot and drive train, with reinforced axle removed. The axle gets inserted in the 24-tooth gear in the worm gear box.
