Need some help with a few moving parts

So, I’m building a sort of contraption thing here… (Image attached) The cylinder inside the blue outsides is a wheel that will be spinning (probably using a tween) and the parts on/in it will be attached via union or something of the sorts.

Here is where things may get a little confusing. The other cylinder outside (going upwards) (which will be taller) is going to move with part of the wheel, as if it is spinning it. I am fairly experienced with building but not really in the realm of attachments and such, so I was just wondering if someone could tell me a way to make this work.

I’m open to any ideas. I did a bit of research but can’t seem to find a article/post/wiki on a good way to do this. Thanks!

(Sorry if this is too vague or if it has been posted before)

I would recommend searching for moon animator on the internet. It is a plugin that can be used for animating characters, models etc. When you have animated the model you will have to use a script in order to play it.
