A new plate for 2014, released as part of the new ball-and-socket parts.

See the below image for a close up of these new parts:
http://4.bp.blogspot.com/-WVBGEBLMKtA/Upuq9eHHntI/AAAAAAAABC4/_tnKjV2X1YI/s1600/DSC05058.png

The position of the edge line by the ball is not perfect, and was placed there to align when using primitive substitution.

And there is a narrowing of the bar at the base of the ball. I don't know if it's worth modeling this tiny thing, but since it seems to be something functional, I tend to think so. See this photo http://4.bp.blogspot.com/-WVBGEBLMKtA/Upuq9eHHntI/AAAAAAAABC4/_tnKjV2X1YI/s1600/DSC05058.png

@MMR1988: Would you be able to advise on the correct location for this
edge line? Would it be similar to part 3731?

@Philo: I had considered this, so will look into modelling it this
coming weekend. You're right in saying it appears functional, as it
stops the new cup parts from slipping free from the towball.

Updated with groove where cylinder meets sphere, and have used new
primitive to implement correct edge lines.

Submitting a new version of this using a primitived ball. This part is now consistent with the other ball and socket parts.

Note I created this part long before the present upload but did not know the part number:

Somehow I see a backward step with this part now.
And in my eyes the old author line should be restored for this part...

I have no need for authorship and am happy to restore that to Owen.

Likewise I'm happy to have the ball part restored (although I foolishly did not download the older version) provided it uses proper primitives for the ball component. I purposefully added the various parts and primitives to the parts forum to ensure that we wouldn't end up with non-primitived ball and socket joints like the existing ones. That is a backwards step and the main reason I overwrote this part.

Owen> Sorry if that all sounds catty. I'm a bit ill today and nothing seems to be coming out right.

I should have merged the two parts together turning the better detailed ball from this part into a primitive for my parts and letting you fix this part. Bad behaviour for which I apologise. Please overwrite my ball primitive with your improved one.

Thanks, Chris, for restoring this to its original form.

Holding because the ball joint and stick should be a primitive. Currently this is defined in ball1.dat which I have credited to C3POwen as author. Note that the edge ring is not included in the primitive to allow it to be used on longer bars if necessary.

I don't belive this to be correct.
No matter how hard I try, I can't see that groove on any of my 15 parts.

Could this be a picture of a pre-production part?

Hi Magnus,

Could you bring this up (with pictures) over at the discussion thread in the forums. There's a bunch of parts affected and likely to be more if past experience is any indication. Makes sense to get everything right at once in my feelings.

Indeed on these protos I can see a line but no shrink. Perhaps indeed it was a feature of pre-production, later removed for one or another of those reasons: ease disassembly of parts, or avoid a weak point that could have resulted in broken parts.

I asked Caperberry about this, here is his answer:
"But in this instance, perhaps I have been unhelpful too! My conclusion that the groove is there to prevent detachment was pure conjecture really; not based on any hard facts from TLG. If there is any functional purpose to the groove, it's clearly not worth distinguishing on LDraw.

Actually I've just had a look at my 14417s and I have both types. Do you understand the production numbers underneath the elements? My grooved ones all say 4-02; the non-grooved have a variety of numbers.

I have no further intel unfortunately. My copies of Legend Beasts were supplied by CEE so I guess there may be a chance these grooved parts were made earlier than the ones Huw bought in December, but there's no way of knowing for sure. For reference, The 2x2 LBG (6063611) that I pictured here http://4.bp.blogspot.com/-_ccxb1xpKrE/Upj7uBlPMwI/AAAAAAAABA8/QJAL8FnhYEY/s1600/DSC04897.png was bought from Replacement Parts back in September. Not sure if people are seeing non-grooved versions of that part also?"

So nothing definitive yet - I guess we have to wait a bit more for these parts to become widespread and then check closely...

I have to say, on the parts I now have from 70125 I cannot see any
trace of the groove, with my initial part being based on the photo
from caperberry's blog, linked above by Philo.

Even without the groove, there is still a fair amount of give with the
bar aligned within the slot on the socket, so any groove that would be
there would not seem functional in regards to the new ball and socket
connection.

Of course, it's a slightly sharper join on these new ball parts than on
the older towball parts, but probably not to the point that the new and
old parts need to be modelled differently.

Perhaps the "joint-8-balla" primitive would provide enough detail?

...especially since the intersection in LDraw file is sharp anyway. I should receive the new parts in the next few days, but I guess only the grooveless version need to be kept.

I got my parts, and was lucky enough to have a part of each "type" in the same set. Imho the version with groove is a test run version - on my part, there is a clear groove on top of the bar, but is smooth on bottom side! And anyway it makes absolutely no difference. I'll post some photos asap.

Thanks for checking.
I've got 11 of 14417 and 4 of 11419, all without the groove.

But how about 15456? That one seem to have the groove. I don't have it yet.
