    His second comment was about the rat rod :)

    Thanks guys, glad you like it. Check out other stuff on my channel :) Thanks, but this is simplistic approach to use mostly technic pieces. I taken the ideas for fender panels and hood from top gear rally RC car. I don't like the fact that front fender is so big though in comparison to rear, and the hood sticking out, so I will try to rework it. I'd like it to be attached in more than one point because right now it's not ideal, that is why I don't like it that much. It feels like a fragile approach. I may think about doing it into something like suzuki cappuccino :) I did a rat rod with engine like this before, so I wanted to figure out a way of squeezing in an engine like this with a steering that is proper for use with a body, but feel free to steal this idea and make a hot rod :) I thought about it initially when I had the linkage steering, but now some parts of the steering need to go under the pistons when turning for the angle to be okay. Also the front construction would be hard to figure out for it to work.

    EDIT: Final version of the model: Instructions on rebrickable: https://rebrickable.com/mocs/MOC-106054 Gallery on Imgur: https://imgur.com/a/M10jtrz Original Post: I figured out a proper steering mechanism for a chassis with full-size piston engine at the front. This chassis doesn't have any issues with leeway on steering or ground clearance. I built a prototype body for this chassis that is easily detachable. I'm not fully satisfied with the look yet, so I will have to iterate more on the body before I'll make instructions for this model. Noteworthy ist that this kind of construction should be also feasible for RC semi tractor where the motors would go where the seats are in this model. Video shows the details, how it works and how the body is being attached:

    I've figured out how to handle this front engine steering: https://media3.giphy.com/media/obMPW4avqCe6VV0QVv/source.gif

    I love this little detail of wishbones going through the system bricks at the front. Great job on this model!

    Adding this concept of front axle around the piston engine at small scale:

    Awesome proportions, nice job :)

    My JCB tractor is a bit fragile, but with ability to make specific parts for sets, the Lego could make something on similar chassis and make more robust top, not necessarily with openable hood. The Lego trailer seems really cool and simple in comparison to my trailer being over complicated and heavy.

    This is next level. Awesome work. The only areas that give away it's a Lego MOC are the bellows and lower part of the front door when looking at this side. It's amazing how it feels non-bricky.

    I love how well it hides RC parts. From the first look I'd guess this is a static/manual model. Those tyres look awesome, definitely would want to get my hands on details like this :D

    The build is awesome, but I love the presentation of the stacking even more. I'm always stuck when it comes to presentation of functionality and you made it look so easy :D

    Amazing model, Great job!

    @2GodBDGlory I've got some of my designs on thingiverse if you are interested in testing printing: https://www.thingiverse.com/saperpl/designs but note that the platform is a bit annoying as it doesn't keep all submitted things in the profile page and I got some feedback that some files can't be downloaded after some time from being uploaded. My models are made for pedantic layer height of 0.12 mm, so it's okay for a small piece, but bigger ones take really long to print. What I would recommend doing is to grab some kind of simple CAD and draw some simple liftarms/connectors to figure out tolerances on your printer. Even if parts that Efferman designed would be downloadable from Shapeways, the same design for SLA printer will most likely not work correctly printed on FDM printer for tolerance reasons. Also note that stuff like ball connectors, the inner ball side, will break off easily with FDM print while Efferman has made some designs with those and they should be okay printed with SLA printer. I kind of feel like it would be cool to have some kind of repository of 3d printable part designs that are lego compatible that have both files for printing and studio .part files that is somehow being organised and controlled by the community, because using thingiverse or grabcad, dropbox, gdrive etc, you're ending up with a mess, but at the same time it seems like a big undertaking to successfully deliver on.

    Yes, exactly. If you don't have the elements in specific colour and some elements for the engine, maybe you could build the model in studio and make the instructions for the perfected version? You have tested mechanical principles of the construction, so making an improved virtual model is not that bad :)

    There is a steering wheel at this scale that can either sit on a stud or on a bar, which would be better than using gear. I think there is enough room to fit a driver seat, but I've got no idea if there is a good way to attach it. Also I'd try to hide every blue pin. The colouring could be a bit better if it was mostly yellow at the back and front and the cab was black, but the black sides at the back make it so that the black fake engine is lost in the black background. Black looks good as accents, unless the model is supposed to be a black car or bike, but big black patches a lot lead to hiding details and feeling a bit messy. And I've done a lot of this with prototypes, so I know the pain. Finally for a fake engine at this scale, I manged to do something really convincing with one type of connector: I think I've seen a lot of different approaches to fake engines at such small scale, but the way you've done it is not convincing to me, that it looks like an engine, sorry :P
  18. SaperPL
    That's a really good use of those wheels. There are some details that could be done slightly better, but overall this is a really good model - great job :)

    Thanks, but it's not ideal - in general linear actuators in lego aren't perfect for lifting the tipper bed in a way it'll work well under actual load, without some additional tricks like a knee redirecting the forces for leverage. But in such small model it's really hard to fit such additions. The issue is that real tippers have those hydraulic actuators placed vertically and they extend multiple times over their base length, regardless of whether this is under the bed or at the furthest end. Closest thing that actually makes sense to me to have the actuator always in correct direction is something like this: https://youtu.be/FNYkpLXe26c?t=76 (timestamp in video): But I'm not really sure how far off this is from the knee redirection method as it's also a lever approach, but with tread instead of beams. The point of attachment is better IMO for heavier loads. Meanwhile Olivierz built the model in blue. https://rebrickable.com/media/users/photos/231361/119652.jp

    The megalodon could be a perfect set if they used the same fin on the tail. The odd number of those fin pieces is weird, but it seems to be coming from how they used the tail piece in the B-model.

    Okay, at first I was like "what's up with not having the PTO here", but after I've seen the steering - wow, this approach to switching steering modes is amazing in its simplicity. Great job.

    Thanks for building, looks good in red :D
