Looks great, thanks!

Thanks berkeman, yes I thought about it. The problem is that I'm very new to mechanical engineering. I learned how to design in solidworks and I think that I can make such part that fit a 8mm rod but I'm not sure what are the limitations of part making in general and who to order the parts...

Many thanks! Exactly. Can you give me a direction on where to purchase the relevant parts? How can it get detached in the easiest way? What good bearings can I use for the linear+radial motion?

Hey, thanks for the fast reply. One correction - the shaft isn't rotating (it's just a cylindrical rail). I attached a quick sketch of what I need, I don't know what bearing to use to for the rotating disc and also, the disc should build momentum somehow at the base and then be able to leave...

Hi, I'm building a toy and I'd like it to spin around a vertical shaft but also move freely up and down while it is rotating. Also, I'd like that the rotating body will get spinned using a gear which will be positioned in a fixed location on the shaft (at the bottom) while the rotating body...
