I don't have a whole lot of LEGO to play around with at the time being. I only have these sets at hand at the moment: bucket excavator 42055-1, Ocean Explorer 42064-1 & Mine Loader 42049-1

So my options are kinda limited with parts, which is why this is only a mock-up. 

I think it would be a better success if I had some actual plates to make a round platform with, but I'm not skilled in that department anyway so yeah.

I tried to build a proof of concept of something like this:

 

I don't know why it lags so much when turning. It works fine if I remove the bracing from the gears, but then everything would just fall apart. I reckon it would be much more consistent if I turned it by meshing a gear with the outer ring. I wasn't able to in this instance.

I think I would have to build the actual seats first to get the actual size right and then go from that, however there's no way that I could manage with only the "few" pieces that I have.

So for now, this proof of concept will have to do. 

The whole thing is being turned only by the star piece in the middle with a 24t and worm gear from an XL motor

I think I got the gearing on the platforms right; one rotation pr. 120°. The whole thing it self is obviously moving too fast.

When making this much bigger, how would you go about getting the gearing right, and in the correct position with barely any friction?

Very impressive as another non-vehiecle technic moc

Nice! Not sure how those part's properties are like as i do not have the mining excavator.

Nice one.. maybe you can use the old technic seats..

Great concept! I also want to build this kind of MOC for a project.

Have you tried to completely balance the machinery? That might help with the jerky motion you see. I also recommend not using a worm gear because of the large amount of friction. It's better to use a couple of "8 to 40" gearings in this setting.

 

Best of luck :)

I reckon the size will be something along the lines of each of the three spinning sections will have a base size of the yellow ring gear rack, and then the entire thing becomes humongus all of a sudden.

I don't wanna try at this time as I am not confident that I have enough variation in my current selection of parts.

I wanted it to be somewhat minifig scale so the old technic chairs are too big to use.

Very Nice Moc. 

By the way I think it lags because there is too much friction
