    Gears-efficient gearbox

    A picture would be nice!

    Keeping score

    That's fantastic - can you show more details of the mechanism? Particularly the detent mechanism part on the right...

    [GBC] Assorted Modules

    These are wonderful! The first two have quite a lot in common with Akiyuky modules, but of course there is no shame in that. The parallel motion linkage in the third one is fantastic!

    Help with gear rack mechanism

    Even simpler would be to replace the differential with a white clutch gear.

    42100 Liebherr R9800 Excavator

    Seems like a new bent liftarm (sorry if this has been discussed already): Oh no, never mind. I think it is just a 5L lined up with a 3L behind it.
  6. So now we are just missing the 32t!

    The licensing thing is a bit of a mystery to me. It does appear that licensed sets sell at a slight premium compared to other sets, and also that they are less likely to be discounted. This does suggest LEGO is paying the partner a fee. If so, why? I would think that on the whole the partner gets the greater benefit from the arrangement - they get a lot of advertising for their product. What does LEGO get? Possibly greater sales because the model is more recognizable, and has an additional stamp of authenticity. But is this effect really significant? Hard to know. Does anyone have any reliable information about it (as opposed to speculation)?

    Lego GBC Cardan Gear Module

    I think I'm going to revise my opinion a bit: this may be my favourite module ever!

    Lego GBC Cardan Gear Module

    Wow - just wow. This is absolutely mesmerizing. It took me quite a while to understand what is happening, and I'm still not sure I quite have it! Would it possible to extend this idea further, so that the two mini-turntables have four positions, say, and the balls stay on the them for several more steps?

    2 hubs, not 1.

    [C-MODEL] 42066 - Shark Mk II

    Brilliant, and so creative! I hope you'll accept a small constructive criticism: to me the small fish doesn't quite seem to match the clean style of the rest. I definitely could do not any better however (especially with limited parts).

    GBC General Discussion

    I like the simplicity! Perhaps add a counterweight to the rotating liftarm itself (opposite end from the pulley, obviously).
  13. I never really found any official sets hard to assemble. (MOCing is a challenge - following instructions I mainly do for relaxation). As others have said, there are many kinds of complexity, but 8043 is high on the list for complexity and intricacy of the mechanisms.

    [ MOC ] T-1000 Soviet Transformer

    Ha ha, only the Russians could think of this - love it! You've done a great job implementing it. The rotating driver seat is a nice touch.

    Why the upper age limit???

    My guess is that age ranges are mostly aimed at adults buying gifts for children who are not their own children. If your own child is into Lego (and you take an interest in what they are into) you know what will sets be appropriate for them. For someone else's child, people don't want to end up getting a gift that's too young or too old. I find it hard to believe any adult Lego fans are put off by upper age limits. Some might be embarrassed about 'playing with a toy' in general, but most quickly get over that!
