But some parts (new ones, like new worm gear) are "out of stock" on the LEGO Service page :(

Thank you. Your opinion, as a great alternate model builder means a lot for me :)

:) Please tell me if you will find something that could be improved in the instructions.

This is how MOCPlans works :)

It was built with using pieces that I had in that time, and I have made only one BL order, for few white tiles and 3L links. I have over 100 000 bricks, so I am not making BL orders too often ;)

Much better. But there are still few things that could be improved :) Another round with this picture: Are you going to make those corner panels on the cab? They are one of the most characteristic parts of this truck. Also, I appreciate that doors open, but that gap could be removed, by using 1x4 hinge plates (but it needs more space inside then): And the doors could have more irregular shape (like the real one). There's also a "step" right under the windshield(s), which is not present in your model. The corners of the roof could be finished with these pieces: You could also rebuild the sun visor in the way I did in the TGS. Am I supportive enough this time? :P

From 16th to 18th September 2015 I was at International Copper Ore Mining Congress at Sandvik exposision hall. Yes, year ago. I was asked to build a model for that exhibition, and under 3 weeks this little thing came to life. Now it is time to show this model, because it will be taken apart shortly :) Oh look mom, it's LEGO! by Marek Markiewicz, on Flickr Sandvik Hardrock Miner MH 620 by Marek Markiewicz, on Flickr Here is how real machine looks: And it differs from what I have build, because it is higly customizable and their look vary. https://www.youtube.com/watch?v=bzJHqOkPq-w I did not had chance to put my model next to real machine, but here you can see it standing on the part of the rear conveyor: Let's start with the looks: The model has two sides, a "nice one", which was wshown to the public: And uggl.... technical, which had lots of tubing and wires sticking from various places. The controller: Main feature (and something that gave me a headache) are the conveyors, which goes trough whole machine: The main conveyor is made of 336 3L tread links and is driven by M motor. As an addition, the conveyor drives the loading stars, by set of bevel gears under the loading table: Conveyor goes right under the turntable that holds cutting boom: The loading table can be elevated and widened. Both functions are pneumatically operated. Second conveyor (so called "tail") is mounted on z60 turntable from Arocs set. The weight of the whole "tail" started to bend frame of the chassis, so I had to put a small wheel under the turntable to prevent it from doing so. Conveyor (270 links) is driven by M motor, and its drivetrain goes trough the turntable. It can be turned by single large pneumatic cylinder, which has enough force to swing it from side to side. Stabilizng plate can be eleveated (two small pneumatic cylinders) In theory this model has propulsion system, driven by L motor, but at the end of the building process it turned out that is not efficient enough to move the model. But on the exhibition it didn't had too much room to move on the table, so it was not a big problem ;) The bolting unit (that something on the top) is moved by M motor, which pulls two rows of chain links (172 of them): The cutter boom, along with cutter head are mounted on the turntable moved by M motor. Its weight caused some bending, but I did not had ideas (and especially time) to improve it. But it worked :) Whole thing is elevated by two large pneumatic cylinders, and the boom can be extended by large 11l cylinder. Cutter head is driven by 47154c01. And bonus pictures with TH5500: Works like this: https://www.youtube.com/watch?v=owHhSYFn3gA Pictures: Bricksafe Brickshelf Flickr It stood over a year on my shelf, because I did not had any will for taking pictures and making video of it. I was tired after that building marathon and it still was my first thought every time I have looked at it. And it probably would stand there another year, but all my my Sandvik models were at Sandvik meeting and it was a last chance for taking a pictures of it in one piece, because it returned to mie in pieces (and is taken apart gradually) As usual, I'd like to thank Sandvik for providing me documentation neede for making this model.

Yes, becuase it drives the worm gear. And as you can see on the video, it works without a problem.

But in my crane superstruture is rotated by a bevel gear, not by pushing it by hand ;) Thank you for your comments, I am glad that you like it :)

After many months (I've started creating this model in March) I'd like to present my alternate model for 42043 set, a Mobile Crane. I always wanted to try making a model with limited amount of parts, and when I connected two buckets to a battery box, I thought that it looks like good counterweight for a crane. And then it all began... It was a bit tricky to rebuild Arocs (a truck with white cab and red crane) into good looking model, but 42043 has a lot of parts that come in neutral (LBG and DBG) colours. Test model had to be build, so I have built it in Liebherr livery :) Finished model: There are 1836 parts used, so it is aproximately 65% of parts from the set. Most of the pneumatic parts are left unused, but almost all gears are used in the model. It has three manual (steering, superstruture rotation and working fake V6) and four motorized functions. They are powered by L motor trough two gearboxes. First one allows to fold/retract stabilizers and fold/retract crane arm. Second one operates winch and pneumatic pump. Making the steering working was a one of biggest challneges, becuase there are no 7L/13L gear racks (and no 4L ones). I decided to use bevel gears. There's a side effect of that solution - due to weight of the model, when wheels are turned in place, there is some backlash. But when all wheels spin while driving around it is almost unnoticeable. Third axles drives the V6: There are no connector blocks for V engines in the set, so I have used few connectors instead. And yes, there is a cluth gear, because I ran out of large gears :) Real fun began with outriggers, because there are only two worm gears in the set, and since one was used in the boom, I was left with only one. Whole outrigger system uses lots of bevel gears, and all are driven by worm gear placed under the turntable. This setup is overcomplicated a bit, but it was the best solution that I could find with given range of parts. It works fine, but you must pay attention while operating it, becuase there is no clutch in the drivetrain. The most important part of this model is superstruture, which consist battery box, L motor and lots of gears with two gearboxes, which make everything work. On the right side: pneumatic switch (for boom elevation), outriggers and boom folding/retracting On the left: pneumatic pump (which could work faster, but since there is no extension driving ring in the set, I was forced to use z12/z20 setup for driving it near gears that are extending the boom) and winch, which could be locked in place. The compressor is hidden behind operator's cab: The superstructure can be moved by turning the z12 on the back: Whole superstructure mechanics with color coding: Two section boom works prety fast, and extending mechanism has linear cluth, which prevents it from damage when boom reaches the end of the gear rack. There is no string provided with the set, but I decided to make an exception, because it gave me oportunity to make a crane. You have a piece of 2m string, right? ;) The hook is made from few parts: Crane at work: And it works like here: https://www.youtube.com/watch?v=SbffFGfSCW4 Pictures Bricksafe Brickshelf Flickr Those 8 months were spent on making instructions for this model. It is divided into submodels (like chassis, cab, boom, superstructure, deck parts etc) and can be bought for $10 at MOCPlans: http://mocplans.com/designer/m-longer/42043-c-model-mobile-crane.html I gave my best to make it clear and easy to use. It was double checked, along with test model. The only tricky part is connecting the superstructure to the carrier and adding deck panels, but it is not a challenge for anyone who build Technic sets :) Sample pages:

It seems that my pretty straightforward style of writing will not work here on EB. I will return to posting my MOCs and not writing anything else in other topics.

Good, and where's the video?

Ok, noted :)

There's a "speculation" and "2017" in the topic, so I am sharing my thoughts about Flagship for 2017.

I'd love to see a succesor of 8455. With new, smaller wheels that will have same tread like Xerion ones and lots of pneumatic 2.0. We had 8421, and after few years 42009 came out, so...

Waaay better. Keep buidling! :)

Finished Metro 2033, starting Metro 2034 tomorrow.

More like model that began to corrode ;)

Excellent part for making perpendicular reinforcements in model frames etc.

Seems so. Also, it means that we will have a worm gear that works with bevel gears.

Finally worm gear that is just ONE STUD LONG! AT LAST! Now I have to figure out where and when I needed that thing...

Thank you ;) I must say that they really fit on this loader.

Now you are trying to change an attitude that I got used to maaany years ago. And It could be problematic to change, because I tell what I think without mincing words ;) Ok, so I think that your model looks like box on wheels, because in real truck cab is not welded to bumper, but there's some distance between those two parts. Now look at the picture I have posted above, imagine that your model's cab is made from three "shapes": bumper, grille, and windshield with roof. Now compare their dimenions to your model, and try to find proportions between those three things. Better?

I have posted these "rude" comments in only two topics so far. And what kind of comment would be supportive? :) Seeing a model that need improvements, but not writing about how it could be built better? Criticism is a part of this whole thing with showing MOCs to others, you post your creation online, because you want to see what others think about it. Problem starts when someone says that he don't like it? Really? About my building experience - few weeks ago I have posted on LUGPols forum my history of building MOCs. I have started with modification of set 7990, many another MOCs were not as good as my last ones, but in every topic I had constructive comments. Not only positive, but also critique, but with explanation what someone does not like and maybe how it could be improved. It really helped on start, and it still helps, even now. And now I am trying to do exactly same thing here, but it seems that it will not work? Are people afraid of being criticised? When someone says that he built a spaceship using his imagination - well done! But when someone says that he built this and this, and saying what it exactly should be, I am starting to compare it to pictures AND blueprints. To see if dimensions, shapes, characteristic parts of the real machine are reproduced correctly. And if something does not fit, I have right to write about it or not?

Hurt? By saying that model should be rebuild to look better? Oh come on :) I am a scale modeler and I am always looking for proportions. Using pictures for reference is good, using blueprints is better. Using both allows to keep dimensions and details of the original machine. But sometimes (like in your case, no offence) it is much easier to build something from scratch, than trying to improve what has been already built. I am aware that here on Eurobricks people got used to see only flattering comments (even when it is obvious that model is bad). And when someone (like me, get used to it, because instead of saying that I like something, I get straight to the things that I do not like) tries to explain that their model is not as good as they think, they are astonished by that type of comment. And keep in mind that I am not saying only something like "Ooo, your model is rubbish", but trying to point out what could be improved, and many times how you could build something in a better way. Also, as a member of this community I am just sharing my opinion about a model with you, and praise is not obligatory.
