Another instant classic! Absolutely love the innovative piston links and automatic dif lock. Epic work!

Looks great! The rear part in dark grey would make it stand out more perhaps. Nice clean lines. 👍

I really like this thread! Its a versatile chassis with lots of options. Fun to see these little puzzles come together👍

youtube and rebrickable have good options to help you moc something

for me its that each model should include somekind of personal innovation somewhere.

I've been playing around with the system, and figured out a tighter mechanism. The Porsche has smaller wheel wells than the Camaro so there should be less forward and backward movement of the axle. This movement is affected not by the moving 'arms' or beams, but by the connector that holds the wheel axle. With a 3-stud length connector, the movement is about 1 stud forwards and backwards. The original design has another problem, which is that the wheel connector is 3x3 in size, and this is too large to fit inside the 49.5x20 wheel rims. That forces the wheels out, which makes the movement much worse. You can use the 49.5x14 wheels of the Camaro, but they don't look as good. So, I made a two stud axle connector, and this has a forward a backward motion of about half a stud either way. Also it fits better in the wheel rims. Sadly, the rotation is a little less pronounced, and the rear arms/beams are weaker than the front ones that have the gears attached. You can adjust the length of the outward arms between 4 and 6 studs. It won't matter. The new axle connector can have either axles or pins through them. The gears need to be changed from 24-8-24 tooth, to a 20-12-20 combination, due to the degree rotation of the arms. Above shows an early prototype. Here it is in the Porsche. As you can see they still touch the edges, but as my Porsche is a shelf queen anyway it will do just fine.

I wanted to see if the system would fit in the 10295 Porsche. So I gave it a shot and I am quite pleased with the result: This is the Targa version (modded a little spoiler with left over parts, and I think the black tires are cooler) So first step was to remove the old system and put in the replacement pivot system. The steering axis had to be moved up one stud, so I made a modified version which is actually better than my original above. I'll add the update to my rebrickable later on. The thin pivot system fits perfectly: I used the 1x4 thin liftarm with wide axle hole together with a 1x5 pinhole thin liftarm. That 1x5 beam holds the gears together to avoid slippage. As you can see below, I used a larger cog together with the 8-tooth and this works really well. The movement of the wheels is now quite good, and definitely better than the original. I'm sure some of you can mod the steering linkage more efficiently, but for a proof of concept first draft I am quite happy with this experiment.

That's a nice option too. I added that idea to the image below. I was thinking of a 1x3 connector with a 1x2 connector, linked with 1x3 thin liftarms:

Cheers for thinking along here fellas! It's possible to use 2 flat 1x4's with a 1x2 pin/axle on the end. Just that it doesn't look great and requires the wheel wells to be spacious. Perhaps Lego will be making those 1x3 flip flop beams that Cada has one day, as they would fix this issue:

Hi all, I got the BMW E30 alternative model of the 10304 Camaro by Firas, which is a stunning rebuild and highly recommended. That model however does not have a steering mechanism due to parts available, so I wanted to create a suitable virtual pivot mechanism that would fit in that scale of cars. https://rebrickable.com/mocs/MOC-196487/ysmajor/virtual-pivot-steering-15-stud-cars/#details It could be that the position of the 1x2 thin liftarms right next to the 24-tooth cog is illegal, as there is a little pressure between the parts when attached. Here it is in the E30. I have changed the wheel rims with something I had lying around, but the 10304 tires are the same size and work well with it. Here is the steering in action (with HOG system going underneath to the backseat):

I hope some smart people out there make some money off MOCs, in any way shape or form, including the Chinese. As for those who care a bit too much, well just look out of the window: you'll see the world moves on and it doesnt care about your feelings. lets just enjoy our toys.

Here is the design of the ring from the aforementioned card tank: https://www.mediafire.com/file/xgtux1ciluvp3gd/ringa_2.png/file https://www.mediafire.com/file/0lzfd5po2ob4v9i/ring_bearing.io/file It shows how the train wheels are suspended between the rings. Hope it helps

Check out the card tank: It uses train wheels in a frame between two 'banana gear circles', that are connected with a large turntable.

This is modelled after the DeHavilland Dash 8 right? Just looking at possible b-model mocs, this set could maybe be turned into a DeHavilland DHC-515.

Like this maybe? I coloured the discs orange to help visibility. https://www.mediafire.com/file/irkkyj5gb749sh2/conveyor01.io/file

Could you use large tracks at 90 degrees and with pins hold up a circular platform in intervals. You can place a disc half a length under the top ones to create a chain without large holes. I'll see if I can whip up an image in studio in a moment.

@thequeenjoI built a minuteman repo mechanism that is an add-on to a pick up bed such as the Ford Raptor. The mechanism can be planted on a structure such as DTU. It's on eurobricks and rebrickable just a simple free moc so maybe it can give you something to work with. https://www.eurobricks.com/forum/index.php?/forums/topic/193020-minuteman-wheel-lift-repo-truck-mod/

A bit off the technic topic but still relevant is Lego Serious Play. I am a high school teacher and have been in school administration before. There I have run some small workshops for parents andstaff using LSP and it is a really fun and effective method of learning. If any of you are looking for ways to incorporate Lego into your day jobs I highly recommend checking out LSP.

Virtual pivot steering was new for me. Also how much difference it makes to upsize car tires on performance, both positive and negative. I'm also constantly reminded when creating structures that 1) nearly everything is possible to achieve with bricks and 2) that when things get really complicated there probably is an elegant and simple alternative within reach.

Thanks @JunkstyleGio! I don't post often and had some issues with the images so thanks for helping out! To install the lift its best to take the back door off. @ukbajadave yes I changed the panels to white, which I prefer (don't have any dark blue!). Also made a bunch of other addons like bullbar and canopy. Once my trailer, winch, and overland rig are done I'd like to put a little video online with all the features. TLG actually made a nice base model to work with, but they just messed up the tires, lights, and rear wheel drive. 😂

Here's a wheel lift to convert your pickup into a repo car: https://ibb.co/kBQSZJ2[/IMG] This lift fits in a 42126 F150 Raptor, but with a little fitting it should go in any similar sized truck. Here's the IO file showing the folded and unfolded position: https://www.mediafire.com/file/f2scexq49ydpnvl/Raptor_Minuteman.io/file https://ibb.co/nrGzJHD https://ibb.co/fnMvg0j https://ibb.co/Mgvq4wj https://ibb.co/3BhfXbd https://ibb.co/HXwHxy0 https://ibb.co/prSNJLQ https://ibb.co/x6fjVKC https://ibb.co/9n3Dvj1 https://ibb.co/fDDHbgj

The coaxial rotor system isn't licensed anyway. As for this H175 I hope the rotor top structure can be lowered by two beams. that would make it look like an H175. Also think that bottom nose window can be brickmade instead of a sticker.

There's a catapult moc out there somewhere with instructions. it's quite good. maybe some kind of amusement park ride would be an idea for this project as well.

Can these pieces be useful in a small functional rotor swashplate? https://www.brickowl.com/catalog/lego-front-wheel-bearing-with-two-knuckles-11949 https://www.brickowl.com/catalog/lego-wheel-hub-46490

I got a McLaren Elva speed champions set the other day, and I wanted to make it more interesting by adding steering. Turns out this thread exists, so I want to show you my latest update. So this is the rear, in my opinion the best looking part of the set: It's an 8-stud wide chassis, and the wheel arches are as tight as a colorful metaphor. So here's the front I got so far, though I've got ideas to improve the look of the wheel arches by using the little 2x2 wing plates. Obviously it won't look like an Elva anymore, but it's got a little muscle car shape to it: Here's the bottom: The steering radius is quite good: The 6x1 flat liftarm turns 10 degrees One issue here is that I needed a part that Lego does not have (I think) but Cada does: So, I don't have a solution yet for getting the same kind of compactness without using this part. In my Studio model I've used another part in it's place that shows the movement of the wheels. The next problem is that the HoG cog turns the wrong way, and it's right where I want to put a windshield. So I've designed a solution to fix both issues. This file compares two versions, and shows the degree of movement of the wheels. https://www.mediafire.com/file/el5w0t81els0lmz/system_steering_1.io/file Here is the file with only the one chassis design: https://www.mediafire.com/file/a9s4zdfj3iyvkri/system_steering_2.io/file I'll try to get some kind of muscle car done in the next few weeks or so.
