See this post for pictures of final result After having put a number of projects on the back burner due to being too lacking skills and/or parts, I figured I should try to build something a) smaller, b) simpler and c) using (mostly) parts I already have. I decided on a small-scale mobile crane, based on the 49.2 mm wheels. I also decided I should start a WIP topic to get feedback and stay motivated to finish (or abandon ship if it turns into a disaster ). I first did some prototyping of the undercarriage in LDD: I'm fairly happy with the prototype, although I'm not fully convinced about the styling of the engine compartment. It looks a bit untidy, but I'm not certain on how to change that without resorting to system bricks. Any advice? This being a WIP topic, I also started building, of course. I violated point (c) above a bit, since it turned out I don't have all the parts, but most is there: So far so good, except the steering long is really poor: (Bricksafe is cropping the image for some reason: find the full picture here.) You can see that the fat tires and the pivot offset in combination with the close spacing does not allow a lot of space for the wheels to turn. I could space the wheels one stud more, but I think that doesn't look right: Upper is the current spacing, lower is one stud more. What do you think, form or function?

Can you use some connectors instead? Or are those too bulky?

Nice progress! Not sure about those exhausts... If I look at the photo's of the real things, they are very "abstract" (point, sharp, "hoekig"), This looks a bit too "organic" to me...

Ah, thanks, changed it! Not that there's much to see there

This is a cool little module. Aside from the spacer no rare or difficult parts as far as I can tell. Just need to get me some balls Thanks for sharing!

Is that usually due to misaligned universal joints? @aeh5040 demonstrated this nicely here: Or was your issue a different one?

They look awesome together! I think I like the C1 the most. I might try a manual version of it (I thought you had one of the three as a manual version, is that correct?) Thanks for sharing!

This is so awesome. The fans are a great addition that really complete the model!

Very nice indeed. Is the scale close enough to your Bucyrus to make some nice photo's together? (1:42 vs 1:48)

Finally, photo's! And worth the wait! The digital model looks great, the resemblance in the comparison pics is very good. Curious to see this come together, I love how you built a dry dock complete with gantry, equipment and (presumably) a few workmen

Beautiful! I love the color combination I'm really wonder how it looks without all the stickers, there quite a lot. I bet it would look awesome as well!

GRAS: "Groen Rechts Aan Stuurboord" (Green Right on Starboard), that's how I remember It's really inspiring to see how you do all those details. So many minifigs that are handless now

Wow, I made it to 4th place. I thought the steampunk (sort-of) looks of my build would not appeal sufficiently, but I was wrong Thanks for all the votes guys/gals! And many congrats to the winners, well deserved!

I'm not always replying, because I don't know what to add... You're building techniques are so detailed that it just blows my simple mind. How do you keep up with the available parts? I often browse through the LDD library to see what's available, but with just Technic parts I can barely keep up, let alone all the System parts... Great model as always in any case, keep it up

Very cool and well executed build! Supported I doubt that a second rocket scale model will make it through the selection, but maybe SpaceX will pick up on it I think the roadster payload works better than the satellite by the way!

I really like how deep you’re digging into this I still have this factory on my to do list, but I never really get to it. I’m following this with interest though!

I saw a suction excavator at a building site near my house the other day. Wouldn’t have know what it was if it wasn’t for your MOC

Wow, this thing is huge! I thought at first that those were the "regular" 62.4 wheels, but I realise now that those are the Unimog wheels... The amount of detailing you put in hides its size a bit (of course, I could've read the dimensions first ). Excellent work If I may have one comment: I think the boom looks a bit misplaced... Not sure if it's the color, the surface of the panels, or the lack of "greebling" or a combination thereof. When I compare it with the detail of the rest of the model, especially the front and engine bay, I can't help but thinking the boom looks a bit unfinished. I'm looking forward to the video! Out of curiosity, is there a particular reason why you didn't close the battery box?

25 :10 8 :6 24 :4 10 :3 9 :2 3 :1 So many great entries, it's difficult to choose! I'm also surprised at the huge variety of ideas. Well done everybody and good luck

An automatic watch does not use electricity. They are fully mechanical. As the counterweight rotates, it winds up a spring which is used to drive the mechanism, much like a pullback. I have a number of such watches, and they typically have a power reserve of 2-3 days, so not wearing the watch for a week will stop it. The device shown in the opening post is power by a small electronic motor and rotates the watch to keep the spring loaded. @Raf H is asking to build such a device using a LEGO pullback motor, essentially proposing to use a pullback to charge a pullback. Alas, my experience with the pullback in my steampunk clock shows that the pullback doesn’t provide enough power for such a contraption. Even if it would, you would have to rewind it multiple times per day, defeating the purpose. I would use an M-motor.

Would it make sense to do a bulk shipping to this side of the ocean? I can imagine it would reduce shipping costs if a large enough number of people would be interested in purchasing one or more items. On the other hand, the logistics and funding of such an operations would perhaps be equally difficult...

That looks really good! Effective use of all the panels. Aside from the linear actuators, how many parts are left from the original trailer? And I don't think the limited space between truck and trailer is a flaw: it looks proportional to what I observe on real trucks.

Ok, now that I'm home I got a chance to look at the video more closely. It's awesome. I though my "clock" was complicated, but this is a whole different level of complicated. And it works! You have my vote

I’m not sure if I understand how it works, but it looks incredibly awesome! Just submit it, why worry?

For those who are interested, some more close-ups of the mechanisms inside Geneva drive: Pendulum and scotch yoke (driven by the yellow pulley wheel): Escapement: High-res versions are in Bricksafe folder.
