[FestivalofMundanity] Scissor Lift
Saberwing40k posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
This is my entry for the Festival of Mundanity, a contest put on by The Lego Car Blog and BrickNerd. To be honest, Technic builds are made for this contest. Up until recently, Technic had many sets that would be considered by many people to be mundane vehicles. Yes, there are flashy vehicles like race cars and dune buggys and stunt planes, but there were also plenty of backhoes and tractors and excavators. Now, it's mostly pullbacks and pretty shells with minimal substance, basically turning Technic into Racers. But, that's a rant for another day. Initially, I had wanted to build a truck with trailer, and include the scissor lift as part of a 3 vehicle ensemble, but ultimately I decided to stick with just the scissor lift, because my depression intervened I decided to make one good model versus try to do three. Plus, the scissor lift is plenty mundane on its own. To really double down on the mundanity, this lift is in the color scheme of the ubiquitous blue Genie scissor lifts. Scissor lifts are really not that glamorous, even among construction vehicles. Like, people don't really see them as cool, and only really buy models or build them out of Lego for diorama purposes. Thus, a perfect fit for this contest. Now, in spite of the apparent simplicity, this model is deceptively complicated. Getting the steering to work to achieve the right steering angle was kind of hard, and the lifting turned out to be shockingly difficult. The lift, at rest. The work deck can extend and retract, just like the real thing. It is locked in place by a spring loaded latch, which is weirdly one of the things I am most proud of. It's a simple, but elegant solution. Just pull the lever... ...And the platform slides right out. The extension locks in both positions. There is an opening door at the back, with a working latch, and a ladder leading up to the platform. The bottoms step of the ladder folds, this is not a feature on the real machine, but a concession to allow access to the steering knob. The ladder folded, revealing the steering knob. The steering was actually somewhat hard to do, it was quite difficult to get the extreme steering angle. Real scissor lifts can actually turn the front wheels almost 90 degrees, to allow for a really tight turning radius. This model can't quite do that, but it's nearly as far, and getting the chassis to be both narrow and flat was hard. Also visible is the reversing box, this is so that the steering knob rotates in the expected direction. Maximum steering angle. The model will actually turn around the inside rear tire, much like a real scissor lift. I actually have firsthand experience with this, I used to work for a certain orange hardware store, in the rental department. Our store had some larger equipment, including scissor lifts, and at times I had to park them. Figuring out how to turn was interesting. Maximum extension. Technically, the lift could go higher, but I could not actually figure out a solution that would work, so I went with the big linear actuator. I originally had a mini LA directly pulling the bottom of the scissor linkage, but that proved to be not up to the task, the clutch kept slipping. The lift has about 19 centimeters of travel, going from a deck height of 8 centimeters to a height of 27 centimeters at maximum extension. The deck is about 15 centimeters long, front to back between the guard rails, and can be extended to 21 centimeters. The lift function is controlled by the 12Z gear at the front. This is really the only good spot for it. I thought this would be better than having both knobs on the back, which would interfere with the rear ladder. In addition, the steering and lift would never be used together. Technically speaking, this is in scale with Technic figures, sort of . The most common kind of Genie scissor lifts are only 32 inches wide, while this model to scale would be more than twice as wide. However, large lifts like this do exist, so I think it still counts. One last glamor shot. Building in blue is hard. Also, the gray connectors at the corners are not random, those are actually tie off points, like real scissor lifts have. I am very happy with this model. It looks right, has pretty much all the functions of a real machine, and was actually finished on time. Just as an aside, this model was inspired by something I had to do at my rental job. Usually, our scissor lifts had to be delivered to job sites, so we had a guy from the vendor that maintained the large rental equipment come out and pick up the lift using a special trailer. The trailer in question was made by JLG, and had a deck that could be lowered to the ground so the scissor lift, with its low ground clearance, could be driven on. I had initially want to replicate the full setup, of the truck, with repair tools, the JLG Triple L trailer, and a scissor lift. I scrapped the trailer because the ramp I built was ultimately still too steep for my scissor lift model to drive on, and there was no way to change that, so the entry is just the lift itself. Later on, after I do some digital work, I might post some pictures of the innards of this thing, it is tightly packed. Thanks for looking. -
[TLCB Lockdown][C-model] VOMAK AT4-V8 Attack Helicopter
Saberwing40k posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
This model was the result of a choice I had to make. I could either come up with an entry for the Eurobricks small car contest, or I could enter the TLCB Lockdown Competition. I really didn't feel inspired to make a small car, so I went with making a C model. I chose 42098, largely because of the fact that it was the only set I hadn't started to mix into my large collection. Initially, I was going to build some kind of wheeled vehicle, but then I hit a real builder's block. At that point, I was looking at the small wheel arches, and thought that it looked kind of like the bottom parts of an attack helicopter cockpit. After I realized that, I made the cockpit section, and got going from there. This helicopter is ultimately a nonesuch, and combines design elements from a number of real and fictional helicopters, including the Hellhound helicopter from Patlabor 2, and a design I found on Deviantart called the Fujin, which was designed by MeganeRid, The rotors spin, obviously, but they also have collective pitch control, which was very hard to implement given the parts available in the set. 42098 includes a shockingly small selection of gears and other technical bits, so I had to get very creative. The rotors are at their lowest position in this picture. The collective does not use a turntable, but instead uses a brick built solution that hearkens back to the very first Technic helicopter, set 852. The actual control for this function is a lever with a red bushing, on the right of the photo. This is the blades at maximum pitch, which better shows the collar that is used to simulate a swash plate. The second most major function is the complex landing gear. A 12z gear at the end of both wings controls this function, which uses worm gears to prevent the gear from collapsing. The first pic shows the gear retracted for flight, the second and third show the gear down for landing. The last set of functions relate to the gun pod, mounted under the fuselage. The pod can be traversed 90 degrees to either side, and will clear the landing gear towers. This is controlled by a 12z gear located behind the air intakes. The gun will also elevate from horizontal to almost vertical, using a knob on the back of the pod. An underbelly view, showing the gun pod, as well as part of the rotor drivetrain. The rotor is spun by the 2 12z gears on the tail. The gun pod, up close. The rubber connectors on the forward fuselage are actually a travel lock, and can hold the gun in place when not in use. Maximum elevation. Or is this depression? I can't decide how you'd define this. On the tarmac. The landing gear do work, but I also built a stand so that this heli can be posed as if in flight, with the gear retracted. Some up close pictures: This detail is actually important. As most of you have probably noticed, this helicopter has no tail rotor, and is not coaxial, so what gives? My vision is that a real version of this helicopter would use a NOTAR system, which uses a ducted fan to effectively replace a tail rotor. That's what the large vents on the tail are supposed to be for. Now, in terms of scale, this model is quite large. CamelHog the hedgehog and Spam for scale. One last beauty shot: The color scheme may not be very military, but I'd chalk that up to this being an airshow/display team livery. All in all, I am quite happy with this model, it was a real challenge to make in the limits of the parts I had, so much so was actually running out of 3L pins, but it came together nicely, and the color scheme actually worked out a lot better than I expected it to. Now, on to the contest. Stay safe out there, folks. P.S. I'll give a shout out to the first person who is able to guess where the manufacturer's name of this heli came from. -
Hi guys and gals, first post here, been following the forum for about 3 years now. Got bitten by the Technic bug with 42046 and here I am today. Recently bought a 42106 for cheap in Bulgaria and after building 42070 earlier the sloped panels got me thinking - there is a truck hood in this. Sooooo, let's make a truck C-model out of 42106! Full size pictures are located here:https://imgur.com/a/wOlijkp The aim of the C model is to be able to tow trailers like the MACK Anthem's one. M Longer inspired me by his 42075 terminal truck. We'll see if I manage to implement it somehow. The chassis is the same from 42106's pickup truck, then reversed a bit. Track has been widened by 2 studs, fenders made wider as well. The rear has dual tires which for the contest will be swapped with a single one just as the front axle. Currently they are a placeholder and proportions tool... I've seen how long the rules topic is so I had to put this text here... Initially it began as the chassis above, trying to figure where to stick the cab: Then after I figured out its placement came time to adjust where the doors would be. Which happen to be the ramps from the trailer. After some further shaping of the fenders and color swaps until it felt right - I got this below. The blue pins protrude for now as everything was just in sketch phase. Makes it easier to disassemble... Final shot of this for now is this: Further will come soon. I hope this qualifies for the contest as it is almost 17 studs high, please let me know if I can enter. If I can't - I'll continue working on the C model aspect of it. Cheers from Bulgaria! p.s. I am entering this C model in the https://thelegocarblog.com/2020/04/30/tlcb-lock-down-b-model-competition/ The finishing touches and updates were made in May, so I hope it qualifies. -
