My dear fellow Eurobricks people,

finally, again after a too long while, I managed to prepare something edible (I hope :blush:) out of the finest ABS we all love so much.

Let me introduce you my take on Kenworth W900...

1%20Naslovnica_YT.jpg

 

I’m a bit ashamed to admit, that this MOC was finished already in early 2018 and it took me until now, to prepare the photos and a video of it. This was built for our LUG’s 20th exhibition KockeFest, that took place in March 2018. It was the time when LEGO Technic Mack Anthem came out, so the theme of Technic section of the exhibition was, naturally, "container trucks and container handling machinery" in same scale as the Mack. We agreed on slightly longer containers, because, let’s be honest, the one on the Mack is a bit too short… so here it is…

17_edit.jpg

 

This whole eighteen-wheeler is some 108 studs long (87 cm) and 16 studs wide (13 cm), well the wheels might be getting close to 17 studs. The truck alone is about 50 studs (40 cm) long. The size of the containers, we agreed upon, was 15 x 15 x 37 studs (+1 for the door handles so 38 actually) and they represented 20 ft containers. As you can see from the photos, my semi-trailer could carry 2 of them.

I used 1 PF L motor for propulsion and PF servo for steering. Another PF L motor was used for remote fifth wheel lock. It could be powered both with standard PF receivers and LEGO AAA battery boxes or with Buwizz. It was all hidden in the cabin’s sleeper. There was another AAA battery box on the trailer to power PF M motor for the trailer supports.

Front axle is not suspended, but uses virtual pivot steering instead. It was the only way to make so tight mudguards above them and although steering angle is not the best, I think it did the job fine enough.

Due to the bulky setup of servo and virtual pivot steering, I was a bit lazy under the hood, so there is nothing else there. I guess I could mock up some engine, but the way the hood was attached (it can’t be opened), it felt a bit pointless.

There is some unrealistic pendular suspension on both rear axles, but I couldn’t do more on such a thin chassis. I used rubber connectors as dampers. Because the chassis is so slim, it slightly twists when throttle is applied.

Here’s how this lady looks topless and below the skirt…

There are some minor details in and on the the cabin, the sleeper was, as already mentioned, filled with electronics.

Since this is a semi, it needs a fifth wheel, of course. It is remotely locked and I totally took the cream off of the brilliant 6x6 Truck with Tipper Semi Trailer by Pipasseyoyo, with great ratchet design for the lock.

Ratchet for the fifth wheel lock below the sleeper…

Fifth wheel + hitch/tow ball (I hope that’s what it’s called)...

4_edit.jpg

 

The trailer was built with Technic bricks - studs down and was sturdy enough for the two containers. It had its own receiver and battery box to operate the supports. The two tandem axles were damped with rubber connectors and adapted to the ground really well. Please forgive me for not filming the movement of the two :wall: :ugh:. I hope the photos will suffice.

Some posing to conclude...

...and a short video of course…

Thank you for reading and watching,

I hope you like it,

Best regards,

Mmmm looks very nice. It’s a pity Lego don’t make thinner tyres in that size :cry_sad:

Great small scale Kenworth Miha :thumbup:

I Like it better than Mack

Yes I totaly agree. The double wheels do look like a couple of rollers, even the single ones at that scale to be honest. But we have to work with what we've got. We can't stick everything  to scale modelling forum :grin:

 

Best regards,

I really should invest in some black flexible/elastic filament for 3D printing. That way I could make tyres and custom Technic wheels.

This is a beautiful Moc!

I like the scale of the Mack, not too big but big enough to add details.

A very good job!

So many great building techniques in such a small chassis, nice work :thumbup: Where does the PF IR receiver for the cab sit?

Your solution of using rubber bumpers as suspension has inspired me to revisit one of my own stalled MOCs with a narrow rear axle, thank you.

I didn't know elastic material could be printed as well. Would be interesting to see hot it turns out.

Thanks! I just realised that there is no version with PF on the photos. There is only buwizz hidden inside the sleeper. But you can see PF version in the video from about 1:58 further, when the truck is shot from behind. Small AAA battery box is on the bottom of the sleeper, where Buwizz was as well, and both IR receivers are at the top of the sleeper, pointing to the back of the truck. It is a bit harder to see because I camouflaged them a bit with black tiles. Feels got to inspire :wink: I hope you finish your MOC.

Ohh, It's Godlike! :laugh:  I saw it at your signature for the first time and it was looking great despite the size and quality of the image but now, with all these features, it's a real work of art!

There were a number of similar trucks on a higher scale (62mm wheels) but fill all thete things into 49.5... A perfect Classic Truck is here!

Thank you @Attika. Yes, you are correct about the L motor. Fifth wheel lock really needs only a small force to operate, so "fuelttank look" of the L motor was it.

I like your truck as well, except the tarpaulin maybe - thicker material would look less like a plastic bag ;-) There are never enough trucks, so I am looking forward to see your new one.

Best regards.

This is great! I really like how this looks and the functionality provides a lot of playability for this scale. Well done!

I have to agree with others with respect to the wheels. For a slightly smaller scale, maybe these or these can be a better option, although I understand that you were now constrained by the scale of the containers.

Which part did you use for the kingpin ("towball")? Is it a bionicle part? I've been looking for a part like that for a long time for my truck, but after seeing the video you linked I'm convinced this is probably the best fifth-wheel coupling for functional models...!

I think everyone else has said what I would like to say, lots of very cool technical ideas that I am going to try out

and for the record, W900's are notorious for bending frames in real life.

I'm very much intrigued by your container carrier, but there seems to be little on the net photo wise..

Very nice rendition of an iconic truck :wink:

I myself planned on building a w900 at this scale. As you have done it very well, I will move to a European truck! 

Nice use of the virtual pivot steering. Too bad your setup is too wide for my needs. I will definitely look at it!

:grin::grin::grin:. Well said. In my defence, the trailer wasn't even in plan yet, but had to do a speedy job to entertain a youngster visitor, so "side curtain" kicked in. :wink: Anyway, thinking of going down to the scale of the mack makes me appreciate even more what you achieved here. :thumbup:

When we decided to go with the Mack scale, we kinda decided for the same wheels as well. I admit the first one you suggest might have worked but have never actually tried it out, although I think I have enough of them. I used "normal" technic ball joint on an axle with additional bush for king pin. I believe Pipasseyoyo used this Technic Ball Joint 2 x 7 with 2 Ball Joints, if I am not mistaken. His is better, because as you can see in his video he could hang the whole truck from it. In my case the ball joint would simply slip off the axle, but then again, my truck wasn't intended for such a wild ride + i don't have this part.

Hahaha, so bending chassis is a feature then :laugh:. There will be a story told about the straddle carrier as well... unfortunately it doesn't have such a happy ending. I rather not promise how soon though, but hopefully - soon :wink:

Maybe you could try a different approach for the same truck in the same scale, although I know it might be a bit hard now, when your mind is "polluted" with my model. Would be interesting to see your version.

Thanks again to all others for very nice words as well. Much appreciated! Somehow, this truck caught an eye of someone from THE LEGO CAR BLOG:blush:
