October 17, 201410 yr Author But there's a new problem: While creating the BOM, it shows a complete wrong part count, a lot of parts are shown double or more. I think it has to do with ghosts/submodels, but I'm not common enough with LDRAW to where I've made errors. In the assemblies the part lists are shown correctly. So I do not know whats the issue. Clearing LPUB cache didn't help. I did not have this problem which is odd since we started with the same file. You will get better results asking the question in the CAD forum.
October 18, 201410 yr The parts list is incorrect, as he stated earlier I've got a more or less part list, by adding LPUB PART IGN commands for parts/submodels, But there was still a difference from two parts where I don't know how the error is produced. So I made a copy from the CAD file where I simply deleted all the Ghosts and Buffer Exchange commands, and I finally got an exact part list. Now I can make the carrier instruction, I'll publish them in next days Greetings Alex
October 28, 201410 yr I am not sure if this point has been made or not, but aside of all the other impracticalities for TLG to create a model like this think of shipping a beast like this. Yes, I know, there are, or used to be 5,000 piece models out there but these were not Technic sets with power functions. Shipping costs would be astronomical! All those motors! If TLG offered free shipping like they do for purchases over a certain amount, they would pay those costs which would simply eat them alive!

Shipping a set so large would be expensive, but it would still be a lot cheaper than paying the shipping on the 20+ Bricklink orders that it takes to get the parts now.
October 29, 201410 yr Hi, Great job so far Is the part list already available??? Blakbird has a complete part list in his last draft4 instructions. But I think we never can have a definitive part list for the crane. Because myself, after building it, changed some few parts, so the part list may be minimal different. At the moment I've more or less finished the superstructure too, I've to mount it and see how much more counterweight it needs. Instructions are on work, an I think that I can publish the complete instructions next month. Greetings Alex Edited November 18, 201410 yr by afol1969
November 3, 201410 yr Hi all, I've now finished to build the crane, and I can now document the build process. There were moderate modifications to do, because there were some discrepancies where I wasn't happy with it. At first it needs lot more counterweight, to have an adequate balance while the boom fully extended. I used a second battery box, but filled with batteries it doesn't give enough weight. So I used steel balls: it didn't need too much modification to the box, I only had to cut out a bit of plastic, it's still possible to put batteries in. I've given some design to the counterweight: Now the boom. I wasn't happy with the fact that the second section hangs over if fully extended as shown in the picture: I've seen it needed more reinforcement, I used a second worm gear an an 8tooth gear. It wasn't easy to make the construction that it had enough stability without design loss. It needed some more tries, but finally I had it. See here: And here the boom fully extended. You see that the boom is more straight now. My 9-year old son is amazed about the size of the crane And the crane with boom retracted: Notice that the counterweight is rather heavy, you can see it give some pressure on the rear axles resp the suspensions. But with less weight, the superstructure hangs too much over. I think I've found a good compromise. But I think that the two actuators (or motors) are too weak to lift up the heavy boom, sometimes the gears are crunching. Indeed a Firgelli actuator should be a better solution. The boom and counterweight modification I'll add to the instructions. Greetings Alex Edited November 4, 201410 yr by afol1969
November 3, 201410 yr Great job, thanks for keeping us updated on the progress :) Funny how MOC builders seem to use their own children to show the MOCs' sizes nowadays
November 4, 201410 yr Really eager to build this myself, looking forward to the completed instructions and must say you are doing an amazing job here. :-)
November 4, 201410 yr Shipping a set so large would be expensive, but it would still be a lot cheaper than paying the shipping on the 20+ Bricklink orders that it takes to get the parts now. Someone should buy the parts for 5 of these cranes and sell them
November 4, 201410 yr Firgelli, or for a more realistic option, maybe use efferman's LA from Shapeways. Has anybody tried it yet? http://www.shapeways.com/model/2595675/xl-linear-actuator-18-studs-stroke.html?materialId=6
November 4, 201410 yr Hi there , if Firgelli actuator were chosen to use in this application , which type/ model of the Firgelli actuator would be most suitable ? Your suggestion please ? Please advise , thanks . Edited November 4, 201410 yr by Blakbird : Trimmed huge unecessary quote.
November 4, 201410 yr Hi all, indeed the problem with too short actuators turns around in my head. I've already thought to buy an Firgelli actuator (the long one). The actuators from efferman seem to be suitable too. But I know that there are some Lego purists here who only want to have 100% Lego. IMHO, why not use parts if they are Lego compatible? As I know, the Firgelli is used in Jennifer Clarks' Demag-AC50, and I must say, it looks very good. At first I concentrate to finish the instructions that I can publish them. If anybody has found a good solution concerning the boom lifting, with Lego or non-Lego parts, whatever, I can make an instruction update. Greetings Alex Edited November 4, 201410 yr by afol1969
November 4, 201410 yr Author Firgelli, or for a more realistic option, maybe use efferman's LA from Shapeways. Has anybody tried it yet? http://www.shapeways...ml?materialId=6 Last I heard, Efferman was still working on improving that actuator, so I have not ordered one yet. I do intend to get one though.
November 5, 201410 yr The optimizing is done. After dust removing, only some grease is necessary. Please note that there are a inside and outside set. These two sets are a little bit cheaper than the full one. Colours are unfortunately impossible because the parts are to big. Edited November 5, 201410 yr by efferman
