Void_S Posted September 13, 2021 Posted September 13, 2021 I rolled this question in my mind for a long time but still didn't find any physical justification for it. However, sometimes I caught myself in setting all the pins equally oriented when building something... Even in TLG official building instructions, I see that sometimes the pins are places with their slots directed longitudinal to connected parts, sometimes traversed. Did you have any ideas why it may be (if not a pure random for sure) done such differently? I guess that having a longitudinal end slot, the connection of two linear liftarms (for example) should be more firm in the longitudinal direction, as the parts won't play compressing the slot gaps, but may have a bigger play in bending. or vise versa.

Stephan Posted September 13, 2021 Posted September 13, 2021 Well, I experienced that the attachment of some sub-assemblies are much, much easier when the pins are aligned in a certain way. You can compress all pins at the same time when attaching such a sub-assembly. Quote
Maaboo the Witch Posted September 13, 2021 Posted September 13, 2021 I do line up axle pins as seen in the manuals because they can only be attached in one of two ways. Same deal with bushing direction. I'm not as fussy with regular pins. Quote
syclone Posted September 13, 2021 Posted September 13, 2021 (edited) I do have an OCD to orient all slots on bushes the same way (and according to adjacent connectors with slots if they have them) , pins on the other hand not so much, only exceptions is when it's a 2Lpin+axle inserted into a 2pin+bush, always alligning the slots. But I know who will be the responsible if now I'll start orienting every single pin a certain way Edited September 13, 2021 by syclone screw touchscreen keyboards Quote
sm1995 Posted September 13, 2021 Posted September 13, 2021 I’m not sure I follow your logic. The black pin shown has 4 slots distributed at an interval of pi/2. This means it’ll have compliance in both x and y directions. You could theoretically reduce the effect of this by rotating it so that the slots are diagonal in the hole, but either way the amount of stiffness you’d gain would so minuscule that it’s purely mind games at that point. just my take. Happy to be proven wrong :) Quote
N-4K0 Posted September 13, 2021 Posted September 13, 2021 Personally I'm a combination of all things mentioned. I need to have all bush slots the same way, the bush ends (for the 1L ones) equally facing inwards/outwards and all pins orientated with the end slots parallell with the length of the beams. Do I have OCD? I don't know, but I suspect I do cos if these things are randomized, I don't like it I also tend to find that the grip of the pins feel a little stronger when they're orientated in the mentioned way with the end slots being parallell with the beams lengthwise.

kbalage Posted September 13, 2021 Posted September 13, 2021 Personally I really don't care :) And I'm almost sure that the orientation in the instructions is totally random, or it only depends on the software they are using to produce them. Quote
ralphie Posted September 13, 2021 Posted September 13, 2021 I align the visible axle-end pins of 32054 to be forward/rear when possible, and up/down otherwise. I put the ring on 6558 in whatever way I think will make it easier to take the model apart, assuming there is no assembly requirement. I don’t pay any attention to slots that are not visible when fully assembled, because I would drive myself crazy with that. Quote
Woodstock89 Posted September 13, 2021 Posted September 13, 2021 I confess that I am also suffering from this kind of OCD ;-) Quote

But the slots in the centre don't do that much. The outer ends can be pressed together which makes insertion in a pin hole easier. Quote

Now the standard building session shall also include a stress analysis for all the connections hahahah Quote
The01 Posted September 13, 2021 Posted September 13, 2021 Yes, the slots of pins/bushes/etc. have to be in the same direction. It is (for me) very disturbing if they aren't. Also, this end of a bush should point to the connection point, the other side to the outside. Quote
DrJimbo Posted September 13, 2021 Posted September 13, 2021 I am semi-obsessive about this since reading on here that it can make it easier to assemble beams with multiple connections, which I think is the case. Anyone else bothered that the box image of 42043 has part 41678 in the grille in different orientations? Quote
Gray Gear Posted September 13, 2021 Posted September 13, 2021 For official models I don't care as I don't build those. But for my MOCs slot orientation matters in some places because the middle slot is useful for pulling out a 3L pin with a small tool. (Some other brands also have pins that grip stronger than LEGO pins, and it can be hard to pull a 3L pin with your fingers if you can't really grip well) Quote
LvdH Posted September 13, 2021 Posted September 13, 2021 The only things I really pay attention to are the pins with stop bush, normal bush and the axle pins. I also make sure the “dot” from the moulding process isn’t visible. Apart from that I really don’t care which way my pins face. Quote
Maaboo the Witch Posted September 13, 2021 Posted September 13, 2021 @LvdH Yup, same with me - I hate it when the moulding mark is visible on beams. I placed a sticker on the marked side of a beam in 42053 and it haunts me to this day... Quote
dr_spock Posted September 13, 2021 Posted September 13, 2021 I pay attention when MOCing with the blue 3L pin. Mainly to minimize the amount I have to disassemble and reassemble as I tweak my MOC. Quote
Thirdwigg Posted September 13, 2021 Posted September 13, 2021 Yep, I line everything up. Slots on bushes, slots on connectors, and slots on pins, and in the case of a pin with axle connecting to an axled liftarm the slots head in the direction the liftarm is facing. I do this on MOCs and sets. Quote
Rebel_Lego Posted September 13, 2021 Posted September 13, 2021 I don’t pay attention to the oriention of normal pins, but with axle pins and 2L pin with bush, and normal bushings I do. I also pay attention to the moulding mark of the beam, and where possible I put an official sticker over it, or I turn it facing inwards the model. Quote

Bartybum Posted September 13, 2021 Posted September 13, 2021 Lol I was wondering how long it would take until this topic would pop up Quote
Alex Ilea Posted September 13, 2021 Posted September 13, 2021 Never paid attention to this, only to bushes' orientation. Quote

I also started suspecting akind of OCD because of these things but who we are if not totally LEGOed People Quote
Johnny1360 Posted September 13, 2021 Posted September 13, 2021 (edited) Lol, yes, yes I do. And here I thought I was the only one. Edited September 13, 2021 by Johnny1360 Quote
