Turntable 2855 accuracy


Turntable 2855 accuracy

Hello everyone,,,
Is the 2855 "Technic Turntable Type 1 Top" known to be inaccurate at all?

I originally abandoned my attempt to position a gear to drive this turntable because it looked like what I was attempting was illegal, but now I think my desired position is fine and it's just an inaccurately defined 2855 part.

The enclosed MLCad screenshot shows the simplest example of the problem. All parts are correctly stud-aligned. But I've raised the red gears to highlight the problem. As you can see, showbox.bio/ tutuapp.uno/ vidmate.vet/ the red gears actually cut into the body of the yellow turntable. I've included close-ups of how much the overlap occurs. I also added the grey gears just to show that no such problem exists between the grey and red gears. The problem is only with the turntable.

Can I safely assume that 8 and 24 tooth gears *can* be positioned as shown?

Hi,
Don't think it's wrong, but your screenshots/attachments didn't make it to the forum...

I think, I know what you mean, cause I remember, that placing 8 teeth gear next to the turntable returns in an overlap of the teeth from the small gear into the main turntable surface. Therefore I would say, something is wrong with this part.

So I measured the part again... and indeed, radius is 2ldu too large (at base and top of teeth).
