    Just finished this very beautiful moc! All functions work very well. Thank you Nico71 for sharing these masterpieces!
  • 1 month ago digimuzik Level 9 MOC Designer
    Finally finished this the last weekend. Thoroughly enjoyable experience all around! Even for my "oops" moment: I was putting on one of the fenders and thinking "you know, I should test out all these levers before continuing"; sure enough one of them seemed to do nothing - oh no! Fortunately, it was just a missing gear on one of the tilting actuators and was pretty easy to replace without disassembling too much.

    The string management is a thing of beauty and of nightmares. First just keeping it from tangling as I built around it, and then wrapping it up just so perfectly (can't have any cross-wrapping on the beautiful underside of this model!). I definitely had to do some careful adjustments with the model upside down and suspended by its forks. But this was such a neat and clever usage of a single string to do the lift. Bravo!

    The steering is crazy tricky to get used to, but hey, that's how forklifts work! Loved all the actions; the adjustable fork width was particularly neat how it engaged at the lowest position. And the tilting cabin was just icing. Very fun experience, and happy to be supporting a talented designer with the instructions purchase!

      Hello, Thanks for the comment, well appreciated ! I am very happy that you like the moc. Indeed the string is hard to set because of the elasticity, that is why I add some schematic in the instructions to show where make the knots.

    Nico71, if I build both the red loader and red forklift out of one set of 42082, is there a list of additional parts I need if I do not want to purchase two sets of 42082?  Just want to find ways to save some $$.
    • 1 month ago Nico71 Level 20 Designed this MOC DESIGNER
      Hello Rudyy, I have found a way to do it, I am not sure it is the easy way. 

      • Export inventory in xml of the 42082-C and D  -> export as / xml, copy code in a notepad, rename the extension from .txt to .xml. 
      • Create a new custom list in -> My Lego / My custom list, 
      • Add then the two inventory (C and D) ->Import / from disk / select file / Append,  do it again for the two inventories
      • Go to My lego / my set list
      • Create a new list, and add the 42082-1 (add set)
      • Untick the other set list (if you have other set that you do not want to compare), in order to have only the list with the 42082 ticked
      • Go to -> My Lego / My custom list / The list with all the parts of the 42082C and D model
      • Click on "build this list"
      • click on change build option / untick "include part", tick "include 1 sets from my list"
      • Re-run with the build option. And tada !
      • You can export then this result in format you want or click on the "buy button" to see which bricklink store have the 714 missing parts (50 lots) for average 100-120€

      Here is the result I obtain, but please re-do to be sure. Mine opinion is that for 110€ you have the missing parts but you have not a additional 42082. Therefore I advise you to buy one more 42082, it will be better for resell it one day if you want, because it will not lost its value compare to a 110€ loose parts lot.

    Hi Nico I just finished builiding your MOC. Great build. I really liked it. Thanks for the effort of creating very clear instructions!
  • 1 month, 2 weeks ago Wiled Level 4
    Hi @Nico71, great build! I really enjoyed building it and the manual is very detailed. Big compliments!

    I made one modification on the gearing for the forklift - for some reason my white 24-tooth gears with clutch that are in the lift up/down movement slip already when I try to lift the pallet. So I modified the gearing (page 103 end-result) to be (instead of 5 times the 4640536 in a row):
    position 1 and 5: remove 4640536, put on 6012451
    position 2 and 4: remove 4640536, change axle to 4560177, put on 4514558 and then put on 4640536 again
    position 3: remove 4640536, change axle to length-7 axle, put on 4227155 or similar and then put on 4640536 again

    Not sure if these parts are "part of the set" but at least this fixes my problem with the clutch gears

    Again, great build, and looking forward to further builds! Note I just bought 42100 which should have lots of opportunities for MOCs!

    I finished this kit today and can only say that Nico has done an outstanding job! From all of my Technic kits, this is one of the most exciting, especially as it is more challenging to build than the original kit (A-model). This MOC shows clearly, that it is possible to make much more out of the original kit than Lego has done. The purchase price of the manual is more than worth its money. Respect, Nico!

        Thanks for the info ihave your pdf file i hope it is the latest
        • 3 months ago Wietze Level 4
          is this the latest version because i dont see on page 36 a 8t gear
          • 3 months ago Nico71 Level 20 Designed this MOC DESIGNER
            If you have buy recently (after the 01 sept), it is the last correct PDF, but if not, I have send you a private message on Rebrickable in order I send you the last PDF :-)
  • 5 months, 3 weeks ago Wusel83 Level 11 MOC Designer
    Very nice, great Job! How did you make the Instruction?
  • 5 months, 3 weeks ago HCM6012 Level 6
    Hi Nico71,
    i previously brought the building instruction from you. 
    as you have revised the building instruction, can resend me the most updated one for me to carry on with the building?
    • 5 months, 3 weeks ago Nico71 Level 20 Designed this MOC DESIGNER
      Hello, there is no major change on the instructions if you have already build the model. You have normally have a mail from rebrickable for getting the new version, it is not on my side. You can also find here in the "purchase section" of your profile on rebrickable :)
      • 5 months, 3 weeks ago HCM6012 Level 6
        Hi Nico71,
        thanks for the info. i saw the PDF file, is that the latest one which i can download? may i know is there any changes? i actually half way through building it till i received a mail, saying there is a newer verison.
        • 5 months, 3 weeks ago Nico71 Level 20 Designed this MOC DESIGNER
          This is the latest one. There is no major change in construction (just some adding for more comprehensive instructions). The only change was done before on the page 39 Step 16 where a 8t gear was missing.
          • 5 months, 3 weeks ago HCM6012 Level 6
            hi Nico71,
            thanks for the updated info. appreicate your clarification. nice MOC by the way! i supportive of your next project! cheers!
          • 5 months, 3 weeks ago bios4 Level 13
            As the instructions got updated once more today, Sep. 1st, I'd like to ask again: what was changed?

            And how about providing some sort of "changelog" within either the file itself, or as a description somewhere on the MOC-page?
            • 5 months, 3 weeks ago Nico71 Level 20 Designed this MOC DESIGNER
              It is written in the description of the moc in changelog : more comprehensive design for the fork, following the return of jcferalv. Again, not major change of a how the model is built, especillay if you have already build it.
  • 5 months, 4 weeks ago bios4 Level 13

    I finished building of the MOC yesterday evening...
    Overall I'm really impressed by the model - the looks are perfect, the functions are really cool.

    I did some minor changes to the overall integration of the battery box, to allow for removing it to change/charge the batteries easier and without the need to dismantle half of the model.

    Unfortunately I also found an issue which highly reduces the playability of the model: the weak rear axle!
    The weight of the model itself alone, and also applying some (even just low) pressure during playing/steering already cause the black 15L-liftarms to separate from the pivot points of the portal axle housings.

    I don't hink that this is caused by my changes for the battery box removal, but I'm not able to "verify" this without rebuilding the whole MOC. Maybe you could check this?

    From my point of view the assembly of the pendular rear axle would need some additional (vertical) "bracing" over both of the black 15L-liftarms (the front axle of set 42081 has such an additional bracing as an example - see steps 29 and 30 in the building instructions of the 42081 A-model)!?!

    Unfortunately there is not enough space in the original design for applying the change without sacrificing either a) the pendular axle or b) a significant amount of steering lock.

    Maybe you have any suggestions of a "quick fix", without the need of redesigning the whole implementation?

    • 5 months, 4 weeks ago Nico71 Level 20 Designed this MOC DESIGNER
      I do not see your modification, so I can not tell if it affect the way the axle is strong. I think if the battery box is no longer part of the chassis, it may affect a little the pendular axle, but not a big point.
      On my side, I have not any problem of strenght on the rear axle, even with 8 month of play. But, my parts is new (only build the model A, B C and D), so I assume the yellow 7L axle (44294) plus beam 5L (11478) have enough friction to handle the 15L liftarm (in fact this is the case for me). So if you encounter problem on it, you can replace the axle 7L yellow by a 8L with stop that you put it from the top, and add 2x 1/2 bush on each side which stick out underneath. This is not very nice, but it works, using the parts of 42082 only.
      If many people encounter this problem, I will consider changing the deisgn of the rear axle.
      Edit : do nto miss also the pin with friction on the 15l in the instructions which participate to handle the axle.
      • 5 months, 4 weeks ago bios4 Level 13
        Thanks for your quick reply, Nico!

        I checked "offline" (without the model in front of me) right now by going through the instructions again, and I'm quite sure that my modifications have no influence on the rear axle...

        In principle I only/just removed all "vertical" pins at the battery box (4x pin 2780 black at the steering side, 2x pin 3749 blue attached to 32013 and the 7L-liftarm at the rear) and changed all pins at the bottom of the battery box to pin 3749 in tan, to allow for lifting it up later for battery replacement.

        Also my parts are effectively new (built the A-model ONCE), so I do not assume them to be the reason; the black friction pin was added to the 15L-liftarm as per the instructions.

        But your suggestion with two 8L-axles plus two half bushes sounds reasonable to me - I will give that a try as soon as I'm back home.

        I wonder if I'm really the only one having troubles with that implementation - but let's see if somebody else enters the debate...

        Thanks for the time being and your help/suggestions!
      • 5 months, 4 weeks ago bios4 Level 13
        Your suggestion (replacing the 7L-axles with 8L-axles with stop and two half-bushes each) stabilizes the axle much better.

        Although this change reduces ground clearance below the rear axle by one stud (it is equal to the towball now holding the string), I will stick to this solution for now...

        • 5 months, 4 weeks ago Nico71 Level 20 Designed this MOC DESIGNER
          I have double checked on my model, and it did not happens, because the two round tile on the 15L liftarm are very close of the chassis and consequently, the 15L liftarm can not be taken apart even if you put weight on it. Do you have make modifications on it ? (see page 34 of the instructions).
          • 5 months, 3 weeks ago bios4 Level 13
            No, I did not change anything there.

            The liftarms in fact were not taken apart completely, but loosened themselves from the pivot points - mainly but not only the bottom one! This resulted in a totally wobbly behaviour and - in the worst case - even an independent steering angle of the two rear wheels.

            But again: applying the two 8L-axles with stop solved the issue for me...
  • 6 months ago jcferalv Level 5
    I have finished your moc. Very hard to assembled. All worked according to the design. The design is wonderful, and the finished model looks impressive, but the instructions are poor. The assembled of the fork (pages 177 and 178) is bad documented. I used the essay and error method. But the assembled instruction for joint the full fork block with the main block are horrible (pages 190 to 198). I assembled first the block of the page 186 direct to the main block using the two beige axes of pages 190 and 194. Then with very patience, the rest of the fork. I didn’t use the official step order. I made many changes. But I’m very happy with the model. Good job.
    Best regards.
    • 6 months ago Nico71 Level 20 Designed this MOC DESIGNER
      Thank your for your feedback, it is important to me ! I will add more picture for putting the fork on the slidding section. Regarding assembling the whole fork with the model, I know this is pretty tricky as it is locked by many element, I have made many version including yours and though it was not a good idea because of the gearing which can be stressed by the construction and consequently do not work after. Therefore I made the choice to have a non-stressing layout even if on some step the parts are not attached. I will think more about it to have a better experience, but please keep in mind my model is not official one, this is normal that it is more difficult, people usually like to find the trick to deal with the difficulty. Nevertheless, I take into consideration your comment to improve the instructions.
      • 5 months, 4 weeks ago bios4 Level 13
        I have made many version

        I have neither an idea how much effort this would mean, nor can I imagine whether this makes sense at all, but what about providing multiple "choices" (i.e. different versions of the assembly) of the most tricky sections?

        Then the builder could decide which one suits best for him...
  • 6 months ago PsiborgVIP Level 18 MOC Designer
    This would be an awesome set, the crane can be a b-model :)
  • 6 months ago jcferalv Level 5
    reached page 79. I turned on the motor and nothing happened. It looks like that the black axe attached at the motor (page 49) connect with nothing. Is this correct? I repeat the instructions two times. 
    Nevertheless I like your moc.
    • 6 months ago Nico71 Level 20 Designed this MOC DESIGNER
      Indeed, it is an error, please add a 8t tooth (ref 10928) on page 40 on the (step 16) on the black axle. It will connect the motor to the gearbox. I am sorry for the mistake, and will correct the instructions !
  • 6 months ago Loxlego Level 13 MOC Designer
    Wow another splendid design!! This one is amazing 😉
    • 6 months ago Nico71 Level 20 Designed this MOC DESIGNER
      Thank you !
      • 6 months ago bios4 Level 13

        really great work on that D-model!
        I had to immediately purchase the instructions when I first saw it...

        By briefly going through them right now I found some issues which I'd like to bring to your attention.

        1) In step 12 on page 53 only two of the four needed "liftarm 1x2 thin black" are processed in the sub-assembly instruction. I would suggest to add them in sub-step 4 of this page, otherwise they could IMHO be easily be forgotten/overlooked during assembly.

        2) In some steps it is quite hard to see where the required parts need to be added. E.g. in steps 14 (page 114) or 15 (page 115) it would be cool to have an arrow-indicator which points to the exact position where the axle and gear need to be added. You use such arrow-indicators in other steps perfectly, so why not adding them here, too!?

        3) To be able to add the two "axles 8 with stop" from step 7 on page 146 without disassembling the "1x9 liftarm black", I would suggest to add them already in step 2 of page 136. Otherwise one has to remove the liftarm to allow for inserting the stop-part of that axle from below.

        This is what I found so far - maybe you find it worth looking into it and correcting it for all further purchasers.

        Keep up that great work of yours!

        • 6 months ago Nico71 Level 20 Designed this MOC DESIGNER
          Thanks for the comment ! I will make the change and uplaod a new instructions :)
          • 5 months, 4 weeks ago bios4 Level 13
            Cool, thanks.

            But the issue with the 8L-stop-axles (point 3 in my comment above) was not addressed - on purpose!??
            • 5 months, 4 weeks ago Nico71 Level 20 Designed this MOC DESIGNER
              Hello, I have corrected all the points and uplaod the new instructions, because the 8L stop is not a relevant point. You have just to put the axle 8L as shown on the picture by underneath, no need to dismantle anything (I have double check with my two beta-builders and they have not encounter any problem).
              • 5 months, 4 weeks ago bios4 Level 13
                Thanks for the clarification - now I see that I was wrong by interpreting how the axles should be added. I apologize!

                I started building the MOC today, and I'm at the steps where the battery box is added. And now my question is: what is the "easiest" way to change batteries???

                From what I see so far the BB is built into the model i a non-removable way, so what am I missing?

                Thanks for your reply an advance!
