Rotating Paddles
Jeroen Ottens replied to Charbel's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Very clever! -
Brilliant little project. I'd never heard of the Glomar Explorer story before, that is cold war craziness at it's best. You did the story right with this model.
-
Very clever front suspension + you captured the lines of the original pretty well. The whole setup looks a bit flimsy, but given the size you work in, while cramming all these features and details in is an amazing feat of engineering.
-
I saw this model appear on TLCB and was hoping you would post it here as well. I just love the shaping of the bodywork. Very smooth and curvy. The use of the rounded window frame as air intake at the rearwheels is inspired. And then inside packed with gearbox, clamshell lids and this interesting opening front window-roof thingy. very nice!
-
Nice one, I especially like the wheels.
-
How about this? Rotating the grey axle will push the green lever with the red clutch gear either left or right. You then have at least two different outputs that you can use to control one track going always forward independent of the direction of the motor, while the other track goes backwards and forwards with the motor.
-
Very ingenious! The operation is not really intuitive, but if you would use (PU-)motors to drive the gearselectors you can hide that in SW. Since the order of switching is fixed it should be theoritically possible to even do this with one motor and some fancy mechanism to switch the levers... Still, I like it a lot.

[MOC] Multicar 4x4
Jeroen Ottens replied to blaz62's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Very interesting concept. It also is a great model to show how intricate you can build in the studless system. So many functions, yet still such a minimalistic chassis. I like it a lot. -
This is a fun thread to watch The CV joints have less backlash than the U-joints, so if possible you can try to use these instead to minimize backlash.

Adjustable suspension
Jeroen Ottens replied to chlego's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
In my Audi R8 WIP topic you can find a setup for an adjustable suspension that not only changes rideheight, but also changes stiffness. and the axle to change rideheight are not stressed in either position. maybe you can use it -
For 5 holes you'd need more than 2 knobwheels in the same plane. In my experience that doesn't work. The friction @Erik Leppen mentions completely blocks the drivetrain from time to time. I never properly tested the slack, but I always had the feeling that knobgears have less slack than normal gears (that's maybe also why they have more friction )
-
Very nice design! This is supercompact indeed. I guess the lower 15x11 frame is not strictly necessary, right? I use the bar with towball instead of these bionicle pieces, there is a slight diameter difference between the two. Have you experimented which one works better? I may have to upgrade my designs to these bionicle pieces. The use of the biscuitpieces in the middle sections is interesting as well. How is the rigidity of this assy? I guess the only real alternative would have been a stack of three beams. Great job.

Amazing model. I know from experience how hard graders are to design. But to get so many functions in such a small scale is mindboggling. I also love that colourscheme, blue with yellow pneumatic accents is just such a nice combo. If you want to make instructions I'd highly recommend LDCad for the modelling of the hoses. It is not the easiest program to master, but once you get the hang of it it is by far the easiest program to route hoses with. Funnily enough one of the details that really caught my attention is the roof. The combination of the curved wedge pieces with the 3x13 panels works really great.
-
Looking good so far. If I may add one more bit of advice. Since you have these nice cut-out drawings of the real plane. When I was working on my Tomcat I found out that following the original planes internal structure was the best way to get structural integrity in my LEGO version. In the Tomcat's case that was especially true for the structure between main fuselage and the rotationpoints of the wings. In this case I would look carefully at the mounting of the engines and wings as @Rudivdk also mentioned. I love the shaping on the rear of the engine nacelle with the 2x5 panels. Very organic. One of the reason I like these kind of builds is that they really challenge you to fit functions, structurale integrity and form into one very tight package. Looking forward to see more progress (even when it is breaking things down to go back to square one).
-
Great looking model and a very nice trick with the angled suspensionparts. I thought that I knew most of the combinations to keep beams in system at angles, but this is yet another way. Great find.
-
I appreciate that sentiment. When I was designing my Audi R8 the Sian’s colour was not known yet. I was hoping for an olivegreen version which would have been a much nicer colour for the Audi than darkazure (or lime). It is just that the Defender really isn’t an easy partspack for supercar shapes.
-
I wouldn’t pick the Landrover as a parts donor for a modern supercar. The lack of curved panels will be killing for the bodywork. maybe there are some really boxy designs from the eighties that you can replicate. even the very angular designs of the extreme Lambo’s will require curves. with the Landrover I’d stick to more utilitarian vehicles like the Avtoros.
-
This is a perfect example why the redesigned gear is an improvement. A couple of years ago this indeed would have been not possible, but now it is.

In the LEGO Bricks & Pieces 66906 is shown with the 4 mm hole instead of the square hole. Now that doesn't mean it will actually look like this (the new pin-with-pinhole is shown as a not having frictionridges, while the actual part does have friction ridges). The older mold pictures don't show the hole, so we can't compare. In the past Bricklink didn't even make the difference between the two molds, so there is a good chance their pictures are not accurate. The relatively new red version also still has the 4 mm hole. Bottomline: I don't expect that the hole is reverted back to the old design.

I made a two mode steering in my Liebherr LTM11200. I explained how I did it in the original topic here on Eurobricks. However, you want to have three mode steering, the only way I see that happening is using a Control+ motor per axle and then hope that SBrick Pro gets released soon (or that LEGO comes with their own programming suite). With these motors (and the associated programming) you can get any steeringmode you want. Not very interesting from a mechanical point of view, but more like real-life vehicles in a way since these are also individually computer steered axles nowadays.
-
Either lower the attachment point in the tractor or mount it higher on the dumpbed. One stud on either side makes a world of difference.
-
There are still ridges on the actual parts, so the render is not accurate in that respect. It is however why I thought of comparing.
-
A new design of an existing element. It happens every now and then. I compared the lime ones with some older black ones and it seems that the lime ones have a little less friction and 'snap' than the older black ones. Not sure if that is because of a design change (smaller ridges maybe) or if that is because of the colour (giving slightly different material properties)

When trying to download this, I got a message that my Flashplayer might be outdated and then some malware tried to install itself... Do you have another hostingsite?

Is it possible to use the older 2L driving ring? The ribbed axle connectors used for that one have a much lower friction than the new 3L axle joiners. But of course either the gears have to move one stud, or the switch has to move half a stud when using a driving ring extension. No idea whether that is feasible in this model.
