    10212 UCS Imperial Shuttle Mod

    M motor may not be enough. This is a single, seriously geared down L motor lifting both wings: https://youtu.be/6cAc_P6rn6o?t=280 With M motor it will be way, way slower (if possible at all). L motor has roughly 50% more torque at similar rpm and is only 1 stud longer.
  2. Thank you very much, guys. I'm really glad you like my model. Oh, yes, I have a very detailed plan for it: it will sit in a cardboard box for months/years :) . Then perhaps it will visit a LEGO event or two (for which I have no specific plans), then return to its box and patiently await that happy day when I acquire more space to exhibit and not just store my models. Sad but true ;) .
  3. Thank you all so much! Frankly, I don't get it either. I would use whatever part I see suitable to achieve more streamlined, realistic look. Does not matter if it's Technic, System or Duplo (see: Duplo caveman fur as driver's seat cover in my old model of DT-75 tractor - not my idea but I used it so gladly :) ).

    Official UCS set versions of popular MOCs?

    One bit of the above is true: you don't remember the story. But it's OK :) . And the story was that I finished my Lambda Shuttle in 2006 and published MLCad file online so that anyone could build it. Soon enough Cavegod and several other builders presented more or less modified versions. Then in late 2008 or early 2009 my friend Adam, fabulously talented LEGO designer, explained to me the dilemma they had: they wanted to issue a UCS shuttle and he was tasked to do just that but he in certain areas of the model (mainly cockpit and wings) he could not come up with better ideas than mine. Basically he said: if you disagree, I will design the model differently and it won't be the best possible but if you agree, I will use your ideas. So I agreed. (For free, if you are curious, because I consider it an honor to be at least partially responsible for the iconic UCS model). So if there was any scandal, it was only with those builders, who took my MLCad file and then forgot to mention who actually designed the model they would proudly present as their own. In case you're interested, here's Adam's Designer Video from 2010: And going back to the topic - if it happened once, it may happen again. People keep designing amazing models and once in a while they happen to be so "set-alike" that it would be foolish of the LEGO group to ignore them. So keep on building and the next UCS may be yours :) .
  5. Thank you again! Indeed, they are acting as if there were no other bright colors in the universe :) . What about neon green, for instance? Or lime, for that matter? I'd love to see a nice lime LEGO excavator. Well, I didn't make any photos during the "metal works" in my basement but I do have the second best thing: in comments section under the photo of my freshly painted cylinders you may a longish but detailed enough description of the production process; just follow this link: https://www.flickr.com/photos/dmaclego/40551517723/in/album-72157702173026262/ Not much to show, I'm afraid - I very much neglected the documenting process during the 18 month work on this model. But I can tell you this: there are two compressors and each of them consists of 4 small pumps and a PF L motor, without any reduction - L motor is strong enough to handle 4 pumps. One compressor is for the bucket, the other one bends the arm. But when the whole arm is to be moved, they work together, one for each cylinder (let's call them "base cylinders"). Curiously, I had to create a separate pneumatic circuit for each of the base cylinders - even though they work together - because diameter of the pneumatic tubing (main suspect: T-piece;) ) proved to be a limiting factor when both compressors tried to pump air into single circuit. Even more curiously, I had to build a very strange controller with five PF remotes to harness this complicated setup (you may see it in the video). The winch, on the other hand, is very simple. Initially I was sure a large linear actuator could act as a brake but as the arm got heavier, it tended to lock. So I went the more primitive way and used PF XL motor with extra reduction, worm gear and two pieces of a very sturdy string. The whole trick was in matching the speed of winch with capacity of the pneumatics to achieve a more or less smooth movement of the arm. All I can show you now is external pic of that mechanism, were you can see the worm gear and rubber tires providing some extra lift (they are not necessary but the system works better this way):
  6. Thank you all, guys. So big and yet so classy - as someone noted, she's wearing boots to match the color of the machine ;) .
  7. Thank you! This is very true and your remark motivated me to take another photo of the model - this time just to ilustrate the scale :) :
  8. Once again, thank you all very, very much. Efferman: considering how much time it took me to build these cylinders, that is not a viable business idea :D . Granted, with some practice I could speed up the process but that's not exactly how I'd like to spend my life :) .
  9. Thank you all, guys. If it really looks like a die-cast model, then mission more than accomplished ;) . About the quick coupling - it may look nice and smooth on film but in reality it's damn hard to find the right angle to grab the bucket :) . It was easier with regular batteries but now, at 11.1 V, the arm moves too quickly. About the linear actuator - it's not there anymore :) . I was sure an actuator would be sufficient as "brakes" for the arm but in the end it wasn't; it's too delicate. I used a simple winch instead.
  10. Hello there! This is my first entry in this part of Eurobricks Forum, so... hello again! Please, let me present my latest creation - a 1:13 scale model of Kobelco SK210 HLC tracked excavator. Why Kobelco? Because of the color, of course. Pretty much everywhere except USA the company sells these excavators in "Kobelco blue-green" livery, which happens to be remarkably similar to LEGO Dark Turquoise. So it's beautiful, it's not yellow and it's challenging enough, since only 216 Dark Turquoise parts were available when I started building it (and most of them unusable like Martian heads). The model includes some custom made parts but the most obvious ones are long pneumatic cylinders - and that's where you can see the similarity, because they are painted exactly that color: Kobelco blue-green. I made them myself, using aluminum, brass tubing and rubber parts from original LEGO cylinders. The other - not so obvious - modification is battery box. I modified it to use 3.7 V li-ion batteries (the same size as regular AA batteries) in two groups, giving it altogether 11.1 V at 1600 mAh. The model worked just fine on regular batteries, too, but now it works faster, as the new battery power both compressor (8 pumps altogether). Other than that, there are only cosmetic modifications: chromed fences, custom stickers and LED lights (these also could easily be LEGO but, strangely enough, I much prefer paying $1 for 10 lights and not $10 for 1 light. The other unusual - but perfectly legal :) - solutions are: hidden winch that supports the enormously heavy arm (so that it doesn't fall like rock) and LEGO tires acting as extra support for the arm. And again: it would work without them but works better with them. And some statistics: 10 motors (plus 2 for the nibbler attachment) 8 small pneumatic pumps maximum reach - 75 cm maximum length - 101 cm width - 25.5 cm ground clearance - 3.6 cm maximum depth of digging: 44 cm total weight - 5.5 kg I'm very glad to write that most of these parameters are very close to the original (considering the scale, of course ;) ). Admittedly, this was partly why I took up this project: to finally overcome the limitations of LEGO pneumatics and create realistic reach for the arm. And that's it, I guess. Thanks for reading and If you feel like commenting on my model - just shoot; I'll try to handle the critique ;) . For more pictures search flickr.com for dmaclego. And substandard video (due to my cameras being unable to record Dark Turquoise - correcting it degraded the picture):
  11. I think you underestimate LEGO designers. in private, most of them build or used to build models on stellar level so it is not a matter of AT-AT being "too difficult" for them. It's all about the rules they must follow as toy designers. Even sets marked 14+ must be robust to a certain degree and buildable for a single person. Unfortunately, AT-AT is, by definition, a very delicate construct and a huge one is extremely hard to assemble for one person. For these two reasons either we'll never get a truly UCS version of this machine or we'll get a big, simplified AT-AT with extra-thick legs, which will cause a massive outcry from adult fans. Actually, the only solution to avoid that is adding some kind of support structure (a stable building to which the model could be anchored) but that would easily double the part count and, consequently, dumbed down the AT-AT itself. All in all, I can't see possibility a REALLY GOOD model of AT-AT in forseable future - but it has nothing to do with LEGO designers' abilities.

    [MOC] Project: Endor

    Project: Endor visited Skaerbaek Fan Weekend in the last days of September. The crew of Beyond the Brick were there as well and I was asked to talk a bit about my work. I'm still determined to create my own film presentation of Project: Endor but in the meantime - here's what BtB guys recorded:

    [MOC] Project: Endor

    Thanks, Jarek. And yes, it is evolving all the time - if not in real bricks, then only in my head, but yest, it is :) . However, implementing changes gets more and more difficult, since with each improvement there is less and less space for another. And I mean it quite literally. With each overhaul more and more parts are becoming "essential" for proper work of mechanisms and cannot be moved/removed/miniaturised. But new ideas keep coming, so... no, it's never over :) . Daniel - sorry, but no chance for instructions. Unless you're absurdly rich and willing to support me and my family for several months, of course :D . Thanks for your kind words, anyway.

    [MOC] Star Wars: The X-Wing Story

    Great job, Jarek! Obviously, you sacrificed certain details (landing gear and guns accuracy, for instance) to make the model buildable for any buyer but overall shape is spot on. I would even say it's as good as possible until we get a proper X-wing windscreen, which is not going to happen antytime soon, I'm afraid. Slightly bent sidewalls make it even more similar to the original. Congratulations!

    [MOC] Project: Endor

    Two quarter domes are 6 studs tall and my shuttle's hull is only 5 studs tall (and still a bit too thick, by the way). So yeah, it's a neat solution but for a bigger model - like the official 10212 or Marshal Banana's Tydirium.
