Yes.
It's some sort of mechanical springloaded, return-to-center, tilt steering wheel axle.
The axles move in opposite directions when the whole vehicle is tilted.
Part number 69963 and 69964.

I must have made a mistake in the beginning, an now the pivot axle is in the wrong place. Angry Crap!
I'll have to figure out where it went wrong.


The mystery of the 2 missing ldu's. - Magnus Forsberg - 2020-12-25

Merry Xmas to you all.

I have a mystery for someone to solve. I'm totaly stuck.
When I look and meassure this part I only find straight lines, 90 and 45 degree angles. Thus the centre point of  the axle must be at 20,20,0, where the 2 red lines intersect.

But when a try to build a structure of real parts around it, the center point of the wheelpin ends up at y=22

So, where do they come from?

Merry Christmas too (and everybody here Wink )
Maybe it's only caused by perspective deformation, and I don't know if this solves the missing 2ldu issue, but I have the feeling that the wheels pins are NOT centered on central bar hole...

I thought so too, but regardless of an offset, or not, it would only move the wheelpins along the 45 degree line.
It needs to be moved along the vertical line.

Or should the wheel-pins be in line with part 4600?

i.e. like in your file put 4600 like this:
1 1 20 16 0 0 0 -1 0 1 0 1 0 0 4600.dat

Dang it, I think you're right! Now I have a way forward.

I made the physical mockup, and then assumed those parts (4600, 21445, 4488) would have the wheelpins at y=22 , but they are at y=21.
There's an awful amount of play in this tilt axle assembly. I think it must be true.

Thank you, Gerald.

Here is a model of the buggy in set 60288, using these tilt steering wheel axles.
   
The axles are rotated +/- 6.5 degrees, and then the whole vehicle is rotated ~5 degrees to be horizontal again.


Escalator Part 69900 - Gerald Lasser - 2021-02-06

BB Posted a review of the huge Ninjago set, where the escalator chain links are in. And the review came with good pictures.

There are a lot of similarities with 57518 and 88323

The one existing sub-part 57518s01 contains a bit too much to be reused, so I split it further, added a s02, s03 and a 69900s01 to complete the party.


RE: Porsche 10295 Rear Mudguard 77182 and 77180 - Gerald Lasser - 2021-03-02

I am working on the rear mudguard of the Porsche.

If anybody has details on the slope (which I loosely modeled after the 1 x 10 Curved slope) I apprechiate a hi res scan or orthogonal picture!

It is a nice challenge for Pathtruder Cool Always fun to tweak the start and end shapes.
