  1. Hello fellow Eurobrickers, Please let me introduce my latest MOC. The Scania P220 Skiploader...... This project started about two or so years ago. It had a stop, start, rocky road to completion! I had the idea and desire to build this for a long time before I eventual got round to it. I set myself a few goals for the model. These were: Functional skip loading capabilities. Steering. Suspension. Fake engine. Working stabilisers on the rear. Detailed interior. Model Team styling. Scaled as best I can to the real Scania. That being said, lets find out if these goals were met..... Functional Skip Loading Capabilities. I think this worked out pretty well. I wanted a manual operation as opposed to Power Functions etc. the main arms are rotated via the black 20 tooth double bevel gears on the sides. They are connected, so both sides will activate both linear actuators. The new longer actuators helped a lot here! The arm extension is done separately by the black 12 tooth double bevel gears. These are independent from one another and drive the gear racks via worm gears so they stay up when raised. The gear racks and housing are a near perfect length, however I found trying to work out the geometry a bit difficult due to the angle of the rear end and stabilisers. And the some what chunky design of the rack housing piece. Here is a funny little GIF showing the motion in action! Steering Yep. Pretty standard in the Technic forum. Nothing more than the good old gear rack actuated by the black bevel gear on top. The turn radius is also standardly large for a Lego model. Suspension I learned a lesson with this one. Model Team style trucks are a little too heavy for the standard hard shocks. I started with independent wish bone and one shock on each front wheel, but soon found out I needed to beef it up with two shocks per wheel when the cab started taking shape. The rear is nothing special. I believe it's a live floating axel? Let me know if my terminology is wrong. This was done using the Unimog ball joint pieces and two yellow hard shocks. The rear suspension is a lot stiffer than the front due to the angle of the shock mounting. Another con for suspension on a model like this is that there is not much space between the wheels and the mud guards, rendering the suspension pretty useless. Fake engine The fairly recent (at least for me) development of fake engines has made squeezing them in a model much easier. I originaly planned to use the Technic piston parts, but this solution is way more elegant. I don't know if the real truck has a v6. But I'm not overly picky on this particular detail. You can also see in the below image where I had to add the extra shocks on the front suspension. A far less elegant solution than the engine, but I didn't fancy a complete re-design! . The pistons are attached to the rear wheels via a differential housed in the ball joint. Here you can see the whole drive train. Working stabilisers on the rear. This part went through countless iterations. My original goal was to make them mechanical using the small linear actuators, but I couldn't find a way to make them small enough to fit with the scale. In the end I decided to make them brick built and to rely on friction keeping them in place. To that end, they are merely aesthetic and have no real function at all. This image shows the basic construction. Note in the real model, I used elastic bands stretched around the rail pieces to aid friction. Detailed interior. I think this came out pretty well. My only criticism would be the amount of black used. Maybe it's my photography skills, but it makes it hard to see the finer details. Here are some pictures for you to decide. Model Team Styling. I'm quite happy with how this model turned out. I had a lot of fun adding all the details and refining the shapes. Especial the front grill, which I really wanted to capture the look of real truck. I'm particularly happy with the head lights. The slight angle was a pleasure to figure out. And the door handles were also a fun little detail to work on. I just wish I could hide the studs on the side of the doors, but maybe it gives a 'Lego feel' I'll let you be the judge of the outcome! Scaled as best I can to the real Scania. So here we are at the last goal. I think it turned out to be about 1:17 scale. In my eyes it's a fairly good recreation of the Scania P220. There are a few bits that could be better, but hey, at the end of the day it's Lego! In conclusion As mentioned before, I had a lot of fun building this. There are a few added bonus points for the tilting cab, opening doors, fold down ladders on the side and a little opening compartment on the right side behind the cab. I usually build a large portion digitally while building with physical bricks, but in this project I kept LDD to a minimum, only serving as a file to keep for the future. There were also a few lessons learned along the way. I think I'll omit the suspension on my next adventure! But I certainly have a list of projects. My only wish is that I had more time..... hope you enjoyed the post. I'll leave you with some pictures. This link will take you to the Scania brochure I used for reference. This link will take you to my Brickshelf page with the Stud.io file. As always, thanks for looking and constructive feedback welcome.
  2. After all this time working on the geometry of the lift and tilt, I am finally ready to show this truck. Full gallery here. The truck features (all manual): Steering, HOG Opening Cab Opening Doors Rear Outrigger Rear Skip Hook (for tilt and lift) Lifting Arms V-4 Engine Trailer with Skip Lock Much more at thirdwigg.com. With Trailer Lift Function Enjoy.
