MP LEGO Technic creations

I'm pleased! You're right but I didn't find any way how to make it possible, because the seat's backside is directly touching the triangular structure which secures the rear arm. Even if it was possible to rotate the seat backwards, there wouldn't be any space for the "drivers legs". In fact, I went through official backhoes sets and found none with this basic, yet necessary function. However, I agree with you that it doesn't well (and is one of the worst things about this models, IMO). I tried everything that came to my mind before used this gear combination but none of the others was acceptable for me. There doesn't seem to be any kind of stress, though. Well, yes. It isn't the most practical way to steer the model but I have a few reasons for that: There isn't any more space through the turntable - 3 hoses already routed there I didn't like an axle going through the seat (which would make using that panel impossible) The model's qiute rear-end-heavy, so when reversing, this solution would allow the front wheels to lose contact with the ground very easily I hope I've answered all of your questions, if I overlooked something, please let me know.

As the model is finished, here's a demonstration video (I know it's not the best one but I hope it'll be enough): Thank you for watching and any advice given during the building process.

19. Backhoe grader This model is based on Hydrema 614 360° backhoe Functions - 10 (6 mechanical, 4 pneumatic): Articulated steering via knob at the back Support legs - two small linear actuators Worm gear-operated front bucket elevation Pneumatic tilting of the front bucket - 1 small pneumatic cylinder Rotating cabin - 56T turntable connected to a knob at the back Swinging rear arm - worm gear connected to a small turntable Rear arm's first section - 1 long thick pneumatic cylinder Rear arm's second section - 1 long thick pneumatic cylinder Tilting the rear bucket - 1 long thin pneumatic cylinder Rotating rear bucket - small turntable Dimensions: L x W x H: 33 x 14 x 21,5 = 9933 cubic studs Video: Topic:

It might be quite off topic but I'd like to ask for advice, whether there is any possibility to use this wheel or tyre with another counterpart?

Thanks! That was my intention - I'm happy you've made the same conclusion. I admit I also like the yellow-black clolour combination but that didn't look good enough for me at this model. In fact, it's absolutely necessary to use all 10 functions to get into this pose (and took me some time to achieve the most effective and smallest one). I hope I'll manage to make a video presentation on time.

@Jurss Looks great! Lime and white aren't the most common colours for a construction equipment but go well with each other and make the grader look somehow special - I really like it. What about the cabin - as I see it, it looks small because it somehow optically seems to be connected with the seat, which is something that doesn't happen when looking at the model from an angle.

Those and many more can be found at @Philo's website: https://www.philohome.com/studio/packs.htm

I'm glad you like it! Thank you. This took me some time to achieve as I didn't have any of those 14z gears before and had tried solving it again and again with standard, recently used ones. However, I like this very much (and there's no more space left for any other solution anyway). Thank you very much! I'm perfectly fine with it. Eurobricks is for fun, sharing anyone's ideas and inspiring each other. Feel free to do everything you want with it In fact, I've also started making Stud.io model of it, here's what I've already done - all hoses and cabin are missing. Special thanks to @Philo for adjustable LAs and pneumatic parts' files for Stud.io.

Thanx! Thank you, I agree with you that the outriggers are much better now. Here's a quick overview of mechanical functions (rotating rear bucket excluded), there would have been a 56z turntable connected to 8z red gear, however it wouldn't be easy to see anything through it then. The blue part is for the outriggers - connected to a small LAs. Unfortunately, I'm not brave enough to try making a 3D model of all those pneumatic components and hoses...

Some other imrovements have been made, now the model is more or less completed. The final dimensions are 33 (L) x 14 (W) x 21,5 (H) when fully folded. I've redone the outriggers, which now have a rubber support for better traction on each side, added mirrors and taillights, made the interior and improved some other things. The rear arm now uses two thick pneumatic cylinders as the thin one was completely weak and useless when actually digging. The studded parts for the front arm were added for better looks and as a counterweight of the rear arm. I'm quite satisfied how implementing all the pneumatic parts turned out.

Looks great, instantly recognizable, especially considering the limited amount of parts - it's a shame that the set didn't contain any gearbox parts, which would allow to make some sort of transmission or some other special functions for this model, though. I really like the use of those ugly headlight pieces, truly original. The only other thing I have to mention, the right name is Ferrari Enzo Ferrari (it may seem odd but the first one is name of the manufacturer, everything else is tribute to its founder). Regards

You're right in both points!

Agreed. It may be just my personal taste but to me the rear mudguards seem to be a bit too narrow - couldn't those be 1 stud wider each? Anyway, I like both models a lot and I'm already looking forward to building them

I'm aware of this issue and admit I've also made better ones. But a problem is still there - the outriggers have to be able to fully retract when the cabin is rotated by 180° to fit in the box and any kind of legs at the end of the arm would stick out. However, as I'm not satisfied with that either, I'll have a look at it once more this weekend .

Thank you! You're too kind!

First of all, I've switched to Hydrema 614 backhoe grader: I also had to omit some of the planned functions - pendular suspension and working steering wheel in exchange to some other, more unusual ones. Pneumatic functions are going to be operated by a large pump instead of the exhaust pipe (black one from 8455 is on the way with some DBG parts for the cabin...) Here's the current state (I'm sorry for all the hoses sticking out from the cabin - all of them are going to be hidden inside): As far as I know, the range of the movement is similar to the real machine. Gear in the center - articulated steering Gear in the left - outriggers Gear in the right - rotating the cabin (oops, please read till the end to know more ) There was no way how to keep the outriggers pneumatic - sorry to all of you, who liked those. I quickly grabbed some Power Puller tyres to demonstrate underground digging. Swinging rear arm - operated via tan bevel gear behind the cabin connected to a worm gear and small turntable. Rotating rear bucket. At this point, here's a special feature of this digger - almost 360° rotating cabin. And here are the possibilities provided by this trick - 13x34x22.5=9945 cubic studs Thank you for visiting & comments are welcome as always!

Feel free to use anything you want . I changed my mirror design to a folding one (maybe I'll upload some photos today) because this one wouldn't easily fit in. Congrats to completing this awesome model and wish you best of luck in the competition (still hope you'll manage to finish the excavator either)!

Then it'll probably merge with the bodywork - what about making it white to contrast with lime and match with wheels and roof? (I know this wouldn't be that practical solution at a real one but still... )

...significantly slower and less powerful. Now about the model itself - it looks pretty cute and tiny! The thing I like the least are probably the white technic panels #1 and #2 at the rear - couldn't those be swapped for smaller #21 and #22 ones? I'd personally prefer all light at one place - moving turn signals towards the center instead one pair of red tiles. But hey, it's still a WIP, so things might differ a lot from the final model.

Maybe I've missed something but is using CADA micro motors (as stated in video) allowed?

I also went on this dealer's website and there seems to be the whole SPIKE Essentials set (unfortunately not for sale), as well as medium and large angular motors (not for sale either). What about ordering in some other country (for exmple Slovakia) - there can be bought for approx. 50€.

Here's the link from LEGO Education's website where you choose your country and find a distributor accordingly. https://education.lego.com/en-us/shop/find-distributor It works, because that's how I got my one.

I wouldn't call it like that... jokes aside, I got your point. Anyway there is no other easy way to make the cabin as rounded as it is now without using system peices. This is how I understand it either. I can't see an exact border between those, maybe ask @Jim for clarification? If I built it in a wrong way, I'll of course make it right, although the result won't be as nice (at least for me). Because micro motors only have studs on them, there's just no other possibility than mounting those on some studs, so IMO that's alright.

Thank you! I believe I've just got an idea how to reinforce it

I know that, I even have a few of them, but still don't know where to place it. Anyway, something will definitely come to my mind...
