XL Turntable

[shineyu]

Now I m going to research a XL turntable for my moc,  now it can take over 10kg and moving smooth . Maybe i need to upgrade 15-20kg.

In this topic, you can see my turntable which can wear 12kg.

And in this video, you can see it with a very large plate, 'https://youtu.be/mx4s8JvnPDg'

Oh sorry, something maybe misunderstood .My turntable not for exhibition or display,  the purpose for my big excavator use.

Take a look at the two Efferman 3D printed turntable with 13L or 17 L diam.

I have used them for use on large cranes - they work very smoothly.

Sorry. Looking at your video, I thought it was for exhibition. Anyway, your turntable looks good enough to me. Why you don't test it with water bottles ?

Because Not enough bottles at my home, so i had tested with books and my moc.

I know 3d print can solved this problems ,but i want try to using lego parts for it.  Thanks for your suggestion

Looking good!

How does it perform when weight is not centered in the middle of it?

Trouble starts when there is more (lots more) weight on one side of the turntable, on a big crane or heavy excavator.

Milan used a ferris side wheel to construct a large turn table for the TC8 crane contest.

Lego Round Brick 13.667 x 13.667 Fabuland Hollowed (47750)

I obtained one but could not figure out to use it - maybe Milan can explain how his turntable was built.

PS for some reason unable to "paste" a link for this part.

Was about to ask you what bearing you'd used, but did a quick try myself and found that the 1x1 round tiles runs really smooth in the slot.

Yes ,i already used 1x1 inside the turntable.

This excavator will be massive...

What kind of excavator are you planning with that turntable? Bucket wheel or conventional excavator?

Wow, what could you possibly want to do with your MOC that is going to require that much strength? Amazing!
