Impressive! I managed to shred some (MouldKing?) ones a while back, but that was with a non-Lego motor

3 minutes ago, gyenesvi said:I don't get how the suspension pivot has anything to do with Ackermann geometry; they rotate in orthogonal planes. I think you misunderstood what I'm talking about (the kingpin is further out than where the suspension is hinged).
I think the idea is that you can then mount the steering link joint inline with the suspension pivot, and simultaneously mount it inboard of the steering pivot. You want to have the link pivot inside of the steering pivot to get the Ackermann geometry, and you want it to be inline with the suspension joint to avoid bump steer, so by separating the steering and suspension pivots in this way, you can have the best of both worlds

That's a pretty fun model! The tubular bodywork is pretty cool-looking too

It is an abridged version of the PDF, more or less the same content but with the chapter on "behind the scenes" removed.
Pricing is approximately $14 US, £11 UK and €13 EU.
The full PDF version will remain free to download for Eurobricks members.
Wow, that's cool that you can make it available that way!

The topic would be for "I like to show something, but I don't have enough for a dedicated topic".
Yeah, that sounds worthwhile!

Though that makes it a 2 1/2 wide thing, and probably needs something to hold the clutch in place (put it on full bush + 1/2 bush instead of axle connector?). So if there was a gear that works directly that's still more compact.
This here is what I've done in the past for a linear connection:
It's not really legal, but it's pretty strong and reliable enough, in my experience.
Still not as compact as a dedicated part, though!

Interesting observations!

Nice job! It's a pretty cool truck you're modeling, and you've got the looks to be very slick! The blue always looks good, too

4 hours ago, Fluwoeb said:I had all the bevel gears engaging using their bevels (or at 90-degree angles to each other).
It was very challenging and there was a lot of half-beam spacing. There was one location where I had two 12-tooth bevel gears on opposite ends of a 2-stud-long axle with a single half-beam in-between them. 
It was pretty goofy and bulky looking. I think if I were to show you I would build it again... (which would probably end up in a slightly different result) because I only had a short video of it and that was a while ago and not filmed well at all. 
The main premise of the design was my discovery of how this and this fit together nicely (though probably not entirely "legal"), so I used that combination instead of the standard 16-tooth clutch gears.
Ok!
That combination of those two parts sounds interesting--I'll have to try it sometime

That's a good question, that makes for some good discussion! Here's a few projects of mine that come to mind:
1:7 Bugatti Chiron:
This thing was absurdly challenging... It had a huge number of complicated mechanisms all trying to coexist in the same shell, which made for major difficulties. I wouldn't say any single function was overwhelmingly complex, though many were fairly fancy, but just making them all work together was very hard!
Transforming Plymouth Superbird:
This one was very challenging because of the large number of folding surfaces that all had to move together, at the right times, and at the right speeds. Adding to the difficulty was that the model didn't have much volume in its transformed stage, so there really wasn't much available space!
Mechanical calculator:
This might be the closest to what you're looking for in this thread! This was one where I was spending days trying to think through the logic of the whole machine, and just trying to understand the theory of how it could work. Tricky stuff!
On 3/15/2024 at 4:08 PM, mahjqa said:The mechanism to store energy in the springs and to release it at the right time was very fiddly. It had to be coupled to a steering axle that could withstand the weight of the car dropping onto the wheels continuously. Weight distribution was also very delicate. On top of that, it had to look good as well.
I hadn't seen that before! Looks interesting and challenging!
On 3/15/2024 at 7:04 PM, Fluwoeb said:I made a 3-speed + R transmission exclusively using bevel gears... that was fun and cool.
Were all the gears engaging via their bevels, or were there double-bevels meshing like spur gears? I'd be interested to see that!
-
Nice job! Sounds like it's quite function-packed!
-
Looks like a fun model! I like the way the body looks, and the tire setup makes me happy!
-
Wow, that looks like it must have been a lot of work! Thanks for sharing!
-
That does look like a lot of fun!
That clone juggernaut trying to take on obstacles with plastic wheels was pretty silly!
-
Should be an interesting set! Hopefully there's some drivetrain/suspension complexity in there.
I really liked the idea of the Defender, so if this manages to be an improved version of that, I'd be into that! Especially since it's got a solid rear axle, which would be more interesting to see than the Defender's independent rear. A 4x4 Squared one (Or even one of their 6x6 models?) would be cool, but yeah, that's less likely.
It's not my favorite car out there--street-styled ones just seem so pointless, but it shouldn't be too hard to mod one to look more like one of the older, more honest, and actually utilitarian variants, like this one:

1 hour ago, Stereo said:And now I'm questioning the old 8880 "CV" balls too since that other thread brought them up. Unfortunately I don't have that set to look closely at how it works. I do have 8444, not sure it's the same part for its swash plate offhand.
Yeah, that uses the same system of parts, I'm pretty sure

19 minutes ago, dantheman12 said:has anyone purchased any 'fake' lego pneaumatic parts? have been wanting to use some for various things mainly for rc scale models do do things such as suspension and diff locking, but the prices for genuine parts are too much for me. I've had some good experiences with fake lego motors from aliexpress, and there are pneuamatic parts available online for much cheaper than the genuine ones. wondering if anyone had any recommendations. thanks

Very nice job! The body shaping and color scheme are both very nice, and it's got some interesting features as well, especially those jacks!
-
Oof! Yeah, high power can be challenging!

That makes sense!

Oh, so you're trying to custom mold them! That sounds like a better solution than just straight 3D-printing stuff, since TPU isn't really grippy enough
Cool! -

1990s Ford F350 Hi-Rail.
Featuring steering, opening doors and side compartments, hood, and a lever that switches the rail wheels up and down. I'll do a more complete write-up when I get a sunny day and can do better photos.
Nice! It's quite an interesting model
Anyways, good job to all the participants, and thanks for joining! I think it was a fun experiment to try, so maybe we can try another one at some point!

Yep, I expect that's what they'll be basing it on!
Though the V8 is still an option, so Lego could go either way, and given that the V8 is more prestigious and likely more compact to implement, I'd guess they'd go that way.
