At the moment they just want to have a poster because of lack of space, but I'm happy with what I can get! Here's the poster. I hope you like it! :)

Thanks so much for all the research you did! I don't expect to sell enormous volumes, so for now I am opting for Bricklink (+ a third party for some bricks that are unavailable or expensive in LEGO). Fortunately, the museum doesn't want a box with anything on it, they're afraid to be accused of IP infringement.

That's indeed very interesting, I'll contact them to see what they have to offer. Thanks!

Oof, sounds complicated.

Hi all! Yesterday, the public transport museum here in The Hague (NL) told me they would like to sell my tram. Happy! However, I only have experience with selling instructions, and they want a box with all the bricks and stickers (made to order, not stocked). I'm hoping some of you have experience with this. Best regards! Steven

Thanks all!

Thanks! Does it go halfway through? What about the top axle hole, does the bar go through there? Thanks everyone so far!

Hi all, a question: Studio allows inserting a bar (in this case a 4L) into the axle hole pictured, but at the same time, the visuals suggest this doesn't fit. I don't have the 67695 at hand to test this. Does this fit, or not? And the other axle hole?

So... which part DOES actually lock with the 61684 turntable base? It seems only a brick that is no longer made does...?

That is a great idea. Thank you!

Thank you so much! So, it doesn't lock? Would you say attaching something to the dish in vertical position would cause it to rotate (e.g. a gun turret)? Thanks so much. So, no friction?

Hi all, can anyone tell me whether the two bricks below lock together? Also, if they do lock, does the dome move discretely or smoothly? Thanks so much!

Thanks! What you are saying made me realize why I am not selling too many of my MOCs... I design toys. AFOLs prefer something more... EPIC... than a cute little bus. :)

Hi all! I finished a bus with the mechanism we developed here. Instructions (free) are here. For people that just need the instructions for the steering mechanism, look here.

Understood. So, the two axle but with pulley wheels. My part shipment got lost by GLS, which is why I haven't built it yet. :)

HOW DID I MISS THIS POST? Geez, wow. I really don't understand why I wasn't notified of your amazing reply. So you would prefer the single axle pivot and not a barrel but a double pulley?

Wow, this looks impressive. It does require a lot of room within a 6-stud vehicle tough, and I think the white 90 degree liftarm would need more space than the 4 studs inside a 6-stud vehicle? Would love to see how it turns.

Great. This puzzle has been fun to solve together. I will do that, adapting the bus now so we have an actual demo vehicle to test. Stay tuned. ;)

You could use 18651 (pin with 2L axle) instead of 6553 and 22961 (axle / pin connector hub) instead of 3749 there. Why change that? :) Very curious. This looks very sturdy and elegant. Does it steer well? Perhaps the sliding axles are too rigidly kept in place? Sure, but we're testing alternatives here, so I guess it comes in handy to have a lot of Technic lying around. I would order a bunch and then end up with having to try a piece I don't have. :D

That's what I thought too. So, do you guys have the bricks to do so? I could order a batch of Technic as well, but currently don't have much Technic except my early 1990s stuff. :)

I think the chassis of the car/bus will be directly above it, so there's no room for it to go up? That does have the side effect of (far) exceeding the 6-stud target size though. Yes, this would also mean you would put the steering axle above that pivot and not in the middle, because the middle will move a little. I guess the only thing we can do to find out what's best is physically build these designs and test them.

For completeness / overview here are the two versions. Yes sorry meanwhile I figured it out. @vascolp, concerning the sliding / wobbling / rotation around the sliding axles, I think this may be remedied by the steering axle on top, you'd probably stick that axle through a ground plate (at least) of the vehicle on top of it? I guess we should test it, but as I said above I don't have the parts. :) Does your version not get a little jammed if you remove the half stud gap between the mechanism and the 1x2 brick with two pin holes? In Studio, I'm seeing some overlap between parts. If there is no jamming, I think adding bushes to the base of the black axles would work best, so we end up with the wheels neatly in the middle of an 8 stud construction. Otherwise, the 1x2 brick would end up on a jumper. Same for @gyenesvi's idea by the way.

Brilliant out of the box thought. Steering angles and wheel position are the same. As far as I can oversee, the advantage is that there is no stress on the pivots, so we can comfortably rotate all the way. With the double axle, there is a little bit of stress / bending. A disadvantage is that the mechanism is connected to the rest of the car in fewer places (3 instead of 5, 1 of which is the steering axle). Another disadvantage may be that the mechanism is slightly wider (but also, it still fits within a 4 x 4 stud space). I think the only way to find out how the double and single axle build compare is by building them. @vascolp or @gyenesvi, do you happen to have the pieces lying around? I've been building mostly with System bricks (which I had as a child and my 6yo currently prefers over Technic). This has been great so far.

Okay, we've found a solution that is sturdy, efficient and compact. Renders below. Can I post it on my Rebrickable, @vascolp? I would also like to open up a new topic on the Technic forum so the build may be more discoverable. I will of course give you credit for your contribution! Send me a link to your website / profile / MOC store and a watermarked version of the demo video, if you like. Btw, I have rendered the mechanism to have a half stud gap between the mechanism itself and the sliding axle ends, because that allows putting everything in a System car without using jumpers. [Edit] Replace the yellow liftarm with the pulley wheel 4185 to have an actual axle hole and to be able to fix the wheel to the red parts with a 1/2 bush.

How about we use 43093 (axle 1L with pin with friction ridges)?
