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

[Auroralampinen]

Well, finally the instructions are done:). 

[Auroralampinen]

well, i had to check. And yes, while this has almost same piece count as 42056(tracked outback dumper 2623pcs,42056 2704pcs). This has a lot more pages, 42056 580 pages, my model 906 pages. Building steps 42056, 856, my model 864:). So hopefully this will be an easy build for unexperiensed buillders:).

[Auroralampinen]

Now this has been submitted to rebrickable. And yes, i had to split the instructions to 2 books, because a single book was too big:).

And please, share your feedback about my instructions. I like to hear your opinions and possible need for improvement areas:). 

[Auroralampinen]

Well, i have a little secret. Now that the 42209 is out, there is no dumper for that scale. So i had this idea brewing in my head, to make smaller Tracked Outback Dumper. For the 42209. And the mini version will have a totally different function set to bigger brother. The mini version uses 2 different speeds for dumping function, and has a block function. For making the different speeds possible, so unloading works slowly, and loading works faster. And this works only one way thanks to the block function. So no acciental backwards rotations:). 

 

[Auroralampinen]

Well, after some tinkering, now the mini model height matches with the 42209:).

[Auroralampinen]

Well, i cannot believe, how well my first attempt to make one way rotation function works. It works so smoothly. And perfectly, im now really impressed and happy:). 

 

[Auroralampinen]

Progress for the mini model. And since the 42209 is electric. The mini model will be also electric, i have build a little battery and electric motor for the mini model:). 

[NV Lego technic]

That seems nice! Also, If I'm not mistaken, you should have [TC29] instead of (TC29) I'm order to enter the competition.

[Paul B Technic]

That is looking good.

Well, now it has been fixed:). 

[Auroralampinen]

Here is the mini version, next to the big brother:). 

Mini version functions. 

Superstructure rotation, 

Slow unloading, 

Fast dump bed lowering.

And a block mechanism, to stop using dump bed functions backwards:).

Your tracked dumper models reminded me of this photo:

Thanks:).

And, i wanted to give the mini model something cool, instead of the power functions. So the different speed bed function with stop/block feature was born. And im really proud how it turned out. It works so well, without any noticeble backlash:). 

[Auroralampinen]

Little bit more work on the front:). 

[Auroralampinen]

All right i wrap up today. And now the cab is done, now only i have to build mudguards, and then the mini model is done. And then i have to make premium free instructions for the mini model:). 

And, i have designed both of these unique. So if you don't have space for big one. And choosed the mini version, you don't miss anything exept power functions. And the complexity is about the same, and both have unique functions. The big one has motorized tracks and power functions, while the mini one has unique dump bed functions:). 

[Auroralampinen]

Well, now the mini model has mudguards:). And now the minimodel is done:).
