That's the theory anyway... It's a neat mechanism and it almost works. Generally, the 2x2s always exit the machine correctly but the 1x1s often don't. It's somewhat front-heavy so there is a bit of a tilt on the body which results in the vertical frame not being exactly vertical. It doesn't seem to interfere with operation though. This is definitely a set that benefits from a video review so I encourage you to watch Sariel's. You can skip past the unboxing and construction to 17m 30s to see the machine in operation. Relatively cheap (yes, I’m dutch). In this set the parts are about € 0.06 cent per part. In for example the Porsche this is € 0.12. Thanks to Evvilspoon, who's also built it, for confirming that it was not just my model that had problems with the 1x1s.
After 225 steps and about 3.5 hours of building the chassis and lower part of the body are complete.Basically, as the conveyer moves an 'agitating plate' is raised when the 1x5 beams on the belt pass under its end, which then drops again once it has passed. This in turn causes three axles under the input chute, mounted at a slight angle and spaced to allow 1x1 rounds to pass through them but not the 2x2s, to move up and down/vibrate as well. The 2x2s travel on top of the axles to their exit on the left (in the photo below) while the 1x1 fall through to theirs, on the right. You can see the ends of the three axles in the picture above. The 1x1s often just sit on the agitating plate and sometimes never exit. This is because (a) they are not spherical and (b) the plate is not completely smooth, so depending on how they land, they don't always roll down it. The plate's up and down movement is not sufficient to encourage them to move! Die-hard Technic fans will want it regardless but if you are on the fence or have limited funds, there are much better Technic sets released this year that I would buy before this one. Now, by this point the model has become so big that it no longer fits on my regular photography table so I was unable to take more photos until I had something bigger. The following pictures are therefore taken with different lighting in a different 'studio' and to be honest I am not that happy with them but hopefully they will serve to illustrate the finished model. Having now built it, I can confirm that it is indeed an impressive machine, but it's really pushing the limits of what is possible with the Technic system and one motor...
Step 8 completes the model with the cabin, railing and other small stuff. The cabin is a little too small for a minifigure.I am therefore not able to wholeheartedly recommend this set: Personally I think it's pushing the boundaries of what's possible with Technic, particularly the Power Functions system, a bit too far and the model has suffered as a result. A third conveyer sits at the bottom of the input chute. It moves much slower than the output belts. The box is the biggest I’ve ever had (42009 and 42030 being the largest yet for me). It measures 57.8 x 47.8 x 16.8 cm and weighs 5970 gram. On the front the main model. After experimenting this morning, I found a simple fix for the latter problem which doesn't solve it fully but does improve things considerably:
