But for everything else, I completely agree. Especially the wheel hubs/differentials. Quote
shroomzofdoom Posted February 12 Posted February 12 (edited) 3 hours ago, Zerobricks said: One thing I like about this piece is that the top row and bottom row are exactly 3 x 3 square. AFAIK, this arrangement doesn't exist anywhere else. It was very helpful to me in building a few gearboxes. I'm sure I can find these in the resale market for a long time. I hated building the old fake motors, I liked that about as much as applying stickers. :-) Edited February 12 by shroomzofdoom Quote
Zerobricks Posted February 12 Posted February 12 10 hours ago, gyenesvi said: The Audi hub cannot be used in live axles, because of the balls built in that cannot be swapped for normal pins. If there were small (L shaped) parts with towball sockets, it would be easier to replace the old hub with the Audi one. But we are not there yet. On a similar note, it would be nice to see a revised version of the planetary hub in the form factor of the Audi hub. It would have more clearance around the steering links, and could be a swap-in replacement for the Audi hub in models. The grey one is easier to lock (also its radius is slightly smaller, needs less clearance), and the ratio is slightly different. But those are marginal differences. That one is actually quite useful still when you need that half stud extra spacer, because in many colors a half stud bush does not exist. Also, that 1 stud end feels to hold more stable than a thin version, even though half of it does not have an axle hole. I actually don't get why that is the case. It would be even more useful with a complete axle-hole end. Agreed regarding hubs, but we are getting new, shorter suspension arms which will be useful for such scenarios. 8 hours ago, msk6003 said: Used on 10261 roller coaster and 71389 lakitu expansion pack for that purpose too.

Thank you for the insight, I retract my statement then. Quote
aeh5040 Posted February 12 Posted February 12 (edited) Can't say I've ever used those hubs, but to me the sliding 8t gears are wonderful and totally irreplaceable. That odd 4L liftarm is sometimes useful. I have a particular soft spot for it because it is used so perfectly in the legendary 8480. Edited February 12 by aeh5040 Quote
R0Sch Posted February 21 Posted February 21 (edited) I've spotted the newly patendet heavy duty joint assembly in the upcoming T-Rex skeleton, which is massive! Edited February 21 by R0Sch Quote
MP LEGO Technic creations Posted February 21 Posted February 21 There seems to be a bunch of 90° technic connectors (#6) in tan as well. I don't know whether anyone ever missed them, still could be useful, though. Quote

Maybe this heavy duty ratcheting joint will be used in the upcoming UCS AT-ST Walker. *snip* It's also interesting to know that the Designer behind this HD joint is Janko Grujic, who designed last year's large City Excavator 60460 (which introduced the 5713 element 3L Axle and Pin Connector). If we look at the upcoming list of City sets for June, we can find two possible candidates 60466 Bulldozer with Front Loader or my main hunch 60467 Heavy Duty Recovery Tow Truck with Crane, an 80$, 793 pcs vehicle probably similar in size as 60409. where this assembly would be of use. Jesus this is such a stupidly clever mechanism... I'm genuinely amazed by it. Hope this means that Lego mech articulation will start improving! Quote
JTS Posted February 26 Posted February 26 (edited) More angles (via @M_longer) Edited February 26 by JTS Quote

R0Sch Posted February 27 Posted February 27 When I see that connector, all I can think about are equilateral truss bridges & crane arms. :) Quote
Ngoc Nguyen Posted February 27 Posted February 27 Speaking of angled connectors, any idea why the angles for #3 and #5 are 112.5 and 157.5? Do these angles have any special mathematical properties? Quote
Zerobricks Posted February 27 Posted February 27 (edited) They are half of 45 degrees increments? Edited February 27 by Zerobricks Quote
gyenesvi Posted February 27 Posted February 27 3 hours ago, Ngoc Nguyen said: Other than that? What else would you need? You get them by halving angles, that's already a nice mathematical property. The two most basic angles are 90 and 180 degrees. You half the angular space between them, you get the 135 degree one. You keep halving the space between those three and you get the 112.5 degree one and the 157.5 degree one. And by the same logic in between 90 and 112.5 now we have 101.25 as #7. Quote

captainmib Posted March 2 Posted March 2 That's an impressive new piece. It seems like you can couple more of them together - maybe for a giant dragon or snake Quote
Lyichir Posted March 2 Posted March 2 The new joint is very exciting. As a fan of themes like Ninjago I'm looking forward to seeing what else it will be used for—Lego mechs/dragons/etc. have been pushing the limits of what existing joints can bear, so a stronger joint like this could create some impressive possibilities.

Do these angles have any special mathematical properties? It matches the previous toothed-bushing connectors https://rebrickable.com/parts/4273b/technic-axle-and-pin-connector-toggle-joint-toothed-with-slots/ which have 16 teeth so divide 360 into 16. I guess being conservative/backwards compatible they didn't want to change that system. Same for the small click-joints that came later, it steps evenly by 22.5. I think the larger style joints have 24 teeth and so they step by 15 degrees instead. Quote
SNIPE Posted March 3 Posted March 3 (edited) I wonder if these new tan 12 tooth gears are compatible with the Daytona yellow gears 22 tooth and 14 tooth. Also, I'm stoked to see this piece being used for something other than as a minifig accessory AND with technic pieces! Shame lego didn't give it any anti studs (yes I own these pieces) Edited March 3 by SNIPE Quote
aeh5040 Posted March 3 Posted March 3 The new joint: the modularity makes me think there may be plans to expand this system further. Quote
