General Part Discussion

[SNIPE]

I was going to suggest simply clamping it - maybe using a GBC ball between some frictionless stud pins, but I guess I was imagining a smaller scale than what you actually needed.

How does that magic work 

I don't really get the question? It works pretty much the same as the boat stud, but since it's also a wheel it's got even less friction in the direction it rolls in.

From the way you originally said it, it implied the wheel only spins in one direction.  Which would be kind of magic.  But you meant it turns in one axis and slides in the other axis like any low friction wheel does.

Here is an interesting observation I discovered.  In building set 10360, there are four of these elements used to connect the engines to the wings. 

in white.  Have of the element is coming off the wing and half it attached to the engine.  Because they are all in white, as are the engines, they match the engine (in color) but not the wings, which are LBG.  

I have the element in LBG.  I thought I would simply separate the element, and combine it with a LBG half.  Separating went fine.  No breaking or weakening the element.  But when I combined the two (one half white, one half LBG) there was noticeable flex in the joint (hinge).  It was no longer firm like it was before.  I switched the  elements back.  LBG with LBG and white with white.  No flex.  So, I correctly conclude that no damage to the elements occurred.  

Thoughts?  Was this simply due to the paint density differences?

There are mold variations (one has a slot hole in the underside of the pin, one has I believe also a round hole) and they're different thicknesses vertically, could be that?  They do have different part numbers on the underside but it's tiny text.

Very good point.  That is likely it.

possible new wheel/tyre: (dark blue)

Not sure if its rubber.
source, maybe there's some other new parts/recolors that people can hunt down

Possibly a black thin bevel gear in the new Gameboy set! Look on the left side, it’s used as the contrast dial.

Here is better image for the 42215 corner tile:).

The new Lego arkham asylum set, seemingly has a new tire mold:). 

[R0Sch]

Spotted black 12T bevel gears and grey 14x4mm tires (2 of each) in the new Game Boy. And what I strongly hope are white 3L pins w/ friction.

Sorry but is this not just the classic LBG 3L pin with no friction???

Yes, but i have not seen it on recent year. Its great that its been brought back:).

Oh yeah it's not been around for 17 years. I think they switched over to tan in 2008

If it's instead the white 3L friction pin, then we're talking 24 years. Only 1 was included in 1 set back in 2001:

There's a fun article about the white pin here:

It's funny they recolor such pieces in small sets, where presumably it doesn't even noticable.. :D 

But I hope it's the beginning of the frequent use of recolorured Technic pins in Technic sets

New Elementary has a new Technics parts review

Some very useful recolours in Red and Black coming out

The black "C" cross block is very welcome :))))

[Zerobricks]

Also, i think New Elementary missed a new mould:

That looks like a 45 degree version, not the usual 22,5 one to me.

[Stereo]

I wonder if you can put a regular 56mm tire (for 15038) on those moon rover wheel faces as well.

Good catch

I wish LEGO had chosen to make the edges of the bent finned panels have a smooth curve instead of an angular one. When used as a transition piece between straight finned panels it feels a bit jarring.
