Fantastic moc! Grave Digger was the first thing I thought when I saw this too.

I had the pleasure of seeing these race cars on display at BrickCon last weekend. The detail is amazing, and I especially liked the sway bars on the cars. I think the dark green car was my favorite, although they are all fantastic. Really nice creations there.

I've purchased several small pneumatic cylinders and small pumps from ebay and bricklink, and all but one leaked. They were supposed to be new too. I've pretty much given up on buying pneumatic parts from either site, but I may not have a choice when it comes to the small cylinders.

lazylegoist, LEGO Education has a pneumatics part pack for a good price. http://www.legoeducation.us/eng/product/pneumatics_parts_pack/2020 It's not really a set per say, but if all you want are some pneumatic components, that's probably the best deal going right now. I've become very weary of buying pneumatic parts from bricklink or ebay. That parts pack doesn't come with any "T" connectors, so you'll have to buy them separately from bricklink or LEGO Education. LEGO Education also sells the air tanks.

The material handler is interesting. So far, it doesn't appear as if any of the 1h 2013 have motors. I wonder if the material handler has a motor and gearbox to control the various functions, similar to the log loader or helicopter. I agree.

That is a good looking tank, although personally, I would not have cut the tracks. Everybody has the right to build and modify as they wish, and if a blog wants to feature a moc with modified parts, they have the right to do that as well. I may have my own rules that I build by, but I don't expect everyone else to follow the same rules. Like I mentioned in my first post of this thread, I do have some exceptions as well. I love the chrome parts on your (bricksonwheels) trucks, as well as the chrome wheels on Crowkiller's cars. Someday, I may have some parts chromed as well.

And I agree with all that, as long as whatever is being built is from 100% LEGO and has no modified parts. When I say "limitations increase creativity", the limitations I'm referring to are just to build from nothing but LEGO and to have no modified parts. When working within the limitation of using just LEGO with no modified parts, it does take creativity to accomplish the amazing creations that I've seen posted by many LEGO builders. A few examples: When Igor built his green John Deere tractor, he was very limited by the amount of green pieces that are available. He had to be very creative to build the tractor using the very limited number of green parts available. The rear wheels on that tractor are another example. LEGO didn't build wheels large enough, but Igor figured out a way to make larger wheels using unmodified LEGO parts. Paul's transmissions are another example. LEGO's gear assortment is fairly limited, but Paul figured out a way to build a transmission with realistic gear ratios and shift pattern. That takes creativity. When building remote control mocs, we are limited by the 8 RC commands. Some of us have built complex gearboxes to allow us to have more than 8 RC functions. Gearboxes are complex and require creativity. LEGO doesn't make really long LA's, but builders like Mahja have figured out ways to build long LA's from LEGO parts. That takes creativity. LEGO hasn't made any return-to-center steering, but builders like efferman and others have come up with creative ways to build return-to-center steering. Even LEGO themselves have come up with some really creative solutions. Take a look at the rotor assembly on the 852 Helicopter. Back then, LEGO had a very limited parts inventory, but they were still able to come up with a creative way to have collective pitch. This is probably the most realistic rotor head that LEGO has ever built, imho, even more so than the current helicopter that is for sale. The above are examples of how LEGO builders have used creativity to find solutions to various problems, all while still staying within the limitation of using 100% unmodified LEGO parts. It doesn't matter what we build, whether it be LEGO, a house, a tall building, a car, or an airplane; limitations will always exist in the world around us. Limitations could include available materials, strength of materials, engineering knowledge, deadlines, environment, cost, technology, or any other factor. Even though we are bound by limitations, it is creativity that helps us push those limitations further and further away. That is how we advance. I'm not sure what is "narrow-minded" about that, but maybe I'm just not explaining myself well.

On the flip side, I think building within the limitations of LEGO parts requires more creativity. I would hardly say it's limiting ourselves, but rather forcing us to think outside the box. Edison was limited by the parts and technology of the day, but he thought outside the box and certainly came up with some revolutionary inventions.

Clever design! I like it.

Actually, there are 4 axles going through, but I just used u-joints for all the functions. The downside to using u-joints is that they don't allow the boom to rotate 90 degrees to the chassis. My stabilizers are in the way anyways, but on my V2 of the backhoe, I'll come up with a different solution. Here's a picture: Let me know if you need any other pictures.

You can also put this tire around a half bushing.

I really like the red engine cover. Looks awesome!

Thanks all! Blackbird, thanks for the tip about using LDVIEW. I'll for sure use that next time. Carsten Svendsen, which section of the boom are you wanting more pictures of? The base of the boom where it connects to the chassis, or where the boom and the stick connect?

Rules I try to follow: 1) No painting of parts, except for chroming. 2) No modifying parts, except for cutting tubing. 3) No non-LEGO parts used. Non-LEGO string is ok, as long as LEGO doesn't make a string suitable for the application. Some other of my own rules I try to use when building my own mocs: 4) No exposed pins. For example, if I use this or , all pins should have a part connected to it. 5) Avoid mixing pneumatics and LA's on the same project. LA's used for articulated steering is ok, even if all other functions are pneumatic. 6) Try to use a single piece to keep two or more gears together (not sure if that makes sense). 7) Avoid stacking more than 2 or 3 liftarms together. The last 4 are just rules I try to follow when I build my own mocs. I don't expect everybody to follow all these rules. :D

I know this is an old thread, but If anybody is interested, I've created some CAD pictures showing the mechanical aspects of the backhoe. This is my first time using MLCAD, and it's by no means perfect, but it gives an idea of the design. The entire backhoe: The drive motors, gear reduction, and steering: Half of the gearbox: The stabilizers with associated motors: The loader LA's with associated motor: The loader bucket LA's with associated motor: Boom slew with associated motor: Boom stick LA with associated motor: Boom stick extension with associated motor: Dipper bucket LA and associated motor: Boom LA's and XL motor. This does not operate though the gearbox.

My understanding is that the Crawler is selling well, but I don't think LEGO will introduce another Crawler in 2013. The current crawler will still be for sale. My guess is the competition is for a new body only. It would be quicker for a fan to create, quicker to judge, and quicker for LEGO to introduce to the market place. What would be neat is for the bodies to have additional motors and functions. Maybe a dump truck with working dump bed, a snow plow with working plow, or a tow truck with working boom and hoist---all built on the crawler chassis. I doubt LEGO would go this route, but it sure would be interesting to see what people come up with! :D

Yeah, that's what we did at BrickMagic. It was very impromptu and not an official part of the event. I'd love to get my hands on a few small pneumatic cylinders. :D

I might be interested, although I'm only about 90% sure I'll be at BrickCon this year. We had a Technic parts draft at BrickMagic last year, and I think we had 15 or so people. We parted out some log trucks. It turned out good, although I think I would have preferred more smaller, non-motorized sets.

Holy Cow, that white Gallardo looks great! The black chrome wheels look perfect on it too.

I tend to buy a model for the parts. I'll buy a set, build it, then take it apart a couple weeks later.

My guess is an orange truck cab.

Looks like a great mod! Your trailer looks well built, and you've done a nice job on those rear fenders. Tri axle log trailers are fairly common here in the US (at least where I'm at). Tri-drive tractors also exist, although most log trucks have two drive axles, or two drive axles and a third drop axle. So, your model is very close to the real thing. Nice job!

Great looking bike! There is some nice detail on the engine. Nice job!

Looks good Andy! Do you have any close up pictures or videos of the variable pitch mechanism? If that is the scale of the engines you are going to use for your propliner, that must be a big airplane!

The Grand Prix Racer looks good! Those pictures are obviously poor quality, but I'm wondering if we will see some new rectangular or square panels. The body work on the Grand Prix Racer looks quite full, and the front wing looks pretty rectangular. Hopefully we'll see some new tires on this as well.
