[WIP] 1/16th Scale MB Arocs (Working on the Cabin)

[2LegoOrNot2Lego...]

Sorry, you've right, saw it later on it uses wheels like 8258.

Well don't be sorry... ...this just happens. Yes indeed those are the wheels exactly...

[Dafgek81]

At first glance it looked bigger.

But as the builder said already, the truck from Toby did give him son inspiration.

So wasn't completely a useless link.

[John Daniels]

The chassis looks very good but as others have said the cab scaling is off.

I personally would rebuild that cab.

You put my plans with the cab into words. Thanks Alasdair!

That's more like it... ...that makes sense!

Really looking forward to any updates, whatever it is...

I completely agree! I'm not sure what happened when I used Sariel's scaler before, but when I made another image and typed in the dimensions it gave me the proper scale. Thanks Ingmar!

Well I finally found some free time to work on my Arocs build, so I spent most of that time adding detailing to the engine.

#8

#9

So there is a turbocharger, oil filters, filler caps, exhaust line, engine oil dipstick, transmission oil dipstick, and a loose representation of the common fuel rail injection system.

I was also able to add the top links to the rear axles, so now they represent the axles in the real Arocs perfectly.

When I have a free hour or so I am planning on making some renders of the chassis and rear axles.

Thanks for viewing and have a good day,

John

That engine detail looks superb! Very well done so far on this build mate

Those are pretty nice details, the way you make that turbo-like thing with the bevel gear and the hoses is just amazing, very realistic, i love it.

[Dafgek81]

The detail you've put in the engine is just amazing

[John Daniels]

Thank you guys, I'm glad that you enjoy the details.

I would like to introduce the newest variant to my Arocs build; tractor chassis variant. 

This is something that I have wanted to achieve in my model to properly allow the modeling of any Arocs chassis variant. The major difference between the previous chassis and this one is in the height. The new chassis is one stud lower. This is very similar to the height difference between the two chassis variants in the full size Arocs. 

 

While I had my camera out I decided to take a picture with the wheels pulled off of the 8x8 chassis. This lets you see all of the suspension components. I also took another close up shot of the engine, which I need a few more to show all of the detail.

As always any constructive criticism or suggestions are always welcome.

Today I would like to show you guys a key feature to increase the realism of my Arocs model build; functioning air brakes.

#14

In early May I came up with a basic concept for forcing a rubber 1x2 against the inside of the rear rims, based off of the brakes that Sheepo used in his Mercedes- Benz 300SL, which can be seen here. I then quickly became stumped on how to actuate the levers, that is where I dropped the whole project due to college becoming crazy. Fast forward to Thursday and the end of the semester, I came back to the project and very quickly discovered the perfect solution to my prior issue, the rear brakes now functioned perfectly. I was going to call it good there and leave the front axles alone, that didn't last long however. So I started designing a braking system for the front axles. A few short hours later and I had functioning brakes on all four axles. After a bit of a struggle routing hoses, especially up front, here I am with functioning air brakes in 1/16th scale.

The rear brakes are actuated by two 1x5 cylinders, one per axle. The front brakes are actuated by two 1x11 cylinders. The brakes work extremely well, under the weight of the chassis the wheels will slip before turning when pulled over a surface.

Please excuse the smaller image, the 800px size seems to be broken for that image.

I hope that you guys enjoyed the update. If you have any questions don't hesitate to ask.

Very impressive at this scale! Did you ask yourself should you, before thinking about how it could be done? As a non-powered model, why would you add a function that is derived from movement? Don't get me wrong, you must have done some amazing work to fit all of this stuff into such a small scale, but do you think it makes sense? 

On a side note your front "leaf springs" look fragile, as the axle could pop out of the connector piece given a sufficient force. The added weight of a cabin may cause problems; however, the lack of heavy pf elements may make your system feasible. I have been experimenting with lego leaf springs for over a year now, so I thought I'd just give you my opinion.

"Why did you do it?" "Because it could be done" 

I think having the ability to have it showcased on a slope like that is already worth it. Great work!

Very impressive leaf spring suspension 

Nice detailed engine - great display model...

I will address the question of why first;

 Your question is similar to asking someone building a technic supercar why they are adding in an adjustable rear wing. The function of the wing uses airflow to create downforce. This function has been implemented even on HOG supercars, but even if the car is motorized using the PF system it will never achieve the kind of speeds necessary to create enough airflow over the wing. I personally added in airbrakes because of the added realism that they bring to the build, since I am striving to build a scale model not just in looks but also in function. I really appreciate the comment, as well as the compliment. 

Now moving on to your second point, I do see what you mean regarding the frailty of the front leaf springs. So far they seem to be holding up. Thank you for pointing it out though. This is my first time implementing leaf springs so I will defere to your expertise and see if I can come up with an elegant way to secure the connectors.

Thank you for the tip, and the food for thought

It certainly is a wonderful feeling seeing the model sitting on a slope as pictured. Thanks for your comment!

I'm glad that my suspension work impresses. Since the real Arocs suspension is so incredibly impressive to me. Thank you for the comment. It's good to know that the hard work is paying off.

Fixed the first paragraph, it needed a reshuffle to flow in a logical manner.

This way it could be used for other trucks (not for Unimog) and is great refreshment in LEGO world to see something like this.  

The only complain is that I did not make it so when creating my MOCs I'll have to think to make something else. 

[Leonardo da Bricki]

Really impressive! I never thought that airbrakes would be possible in this small of a scale. Looking forward to more of this Arocs.

[John Daniels]

I have a new update for you guys. This time with a section of the build that is truly "in progress."

I have been working on the cab for my build. I spent the last few months flipping back and forth on whether I wanted to go full Technic on the cab or to build it in Model Team style. I eventually opted for the latter option as it allows me to recreate more details. Here is what I have so far;

#18

I believe that the cab so far should satisfy your desire for something new @MaxSupercars As always I am open to suggestions for improvement, this build wouldn't be where it is today without your guys help. If any more photos are needed, please let me know. There is also a complete dashboard on the inside, but that will be saved for a later update.

Thanks,

John
