[TC29] tracked outback dumper and mini tracked outback dumper with free instructions

[Auroralampinen]

So, here are the final functions. 

Big brother, 

Motorized independently operated tracks, 

Motorized superstructure rotation, 

Motorized dump bed operation, 

Opening doors and frunk.

And working inline 4 engine. 

Little brother,

Crank operated superstructure rotation, 

Crank operated dump bed functions, 

Dump bed raises slowly. 

And lowers faster, 

Dump functions work only one way. And there is a block mechanism, wich stops accidental backwards operations. 

Opening doors and frunk, 

Non working electric motor and battery detail:).

Here is a test video for the mini model dump bed operation:). 

 

And, in case you are wondering, yes the mini model has the same bogie design as the big brother. Only the minimodel one is smaller, and without motor connection:).

And, since every electric construction machine(like 42209 and 42175) needs a portable battery charging station, the mini model is no exception. The mini model has a portable battery charging station. Thought a little bit more advanced, since it include inline 3 engine generator to charge the battery pack. Plus the battery sells are removable. The 42175 battery was just a sticker. The minimodel includes a brick build adaption of battery cells:).

Good morning, today i will start making premium free instructions for the mini model. I yesterday completed the undercarriage instructions, and the instructions version will have rubber inserts for the tracks, for better playing experience:).

Well, i tooked couple days off from building. And now i returned. And since i want to give best playing experience, i decided to add couple wheels on the mini model. Now the mini models tracks roll on all surfaces, and now the tracks move a little electric motor replica:).

[Auroralampinen]

Here is a little behind the scenes sneak peak, of my process to making a 3d model. And yes, i do destroy the model to make 3d model. And after the 3d model and building steps are done. I will put back together the physical build:).

[NV Lego technic]

That seems like a lot of work, making me appreciate it even more.

Yeah, but the model size is mini and small:). 

[Auroralampinen]

And in case you are wondering, yes the minimodel will come with free slightly fine tuned new gen 2.1 instructions. The gen 2.1 improves on the manual splitted into 2 books. Because the big brother instructions were my first wich were divided into 2 books. The divide was not perfect, and the mini model will improve on this regard massively:). 

[Auroralampinen]

Well, i had an huge disater. My computer decided to update it self in the night. And now studio is corrupted, i have to do this again from scratch😑

Well, luckily after some looking. I did save the non corrupted file. And thank god that i don't have to do this again. So happy days:). 

[Auroralampinen]

And, here is the instructions generation update list. So you have clear understanding, what different gen instructions mean:). 

Gen 1, my first attempt to make instructions. But they failed and are really bad. 

Gen 2, all the gen 1 instructions issues were fixed. And the instructions were simplified a lot:). 

Gen 2.1, updates and fixes for 2 book design:).

[Auroralampinen]

All right, now the instructions are done. Happy days:). 

[NV Lego technic]

You too:)

[Auroralampinen]

here is minimodel instructions:).

[Auroralampinen]

In case you are wondering, yes both have similar dump bed operation range:). 

[Paul B Technic]
