Red Mini Excavator (Pneumatic)

[fresko]

Hello again!

I made a small moc some time ago, but I didn't had time to publish it (due the buzy weeks at school).

It's al little pneumatic creation (my first fully pneumatic), with 4 functions: A 3-section boom and a little backfill blade. Naturally it works with 4 valves.

For the air pressure, I used 1 external big, manual pneumatic pump, because I didn't want that the model included batteries or other electric parts. Off course you can

make an external electric pump. It was a challenge to hide all the tubes in a small space.

And to end, a video:

Please tell me what you think and how I can improve it!

If there should be enough interest in instructions, I can make them.

Greets,

Fresko

Nice start.

I think you need to make a cab of some sort to enhance the look of the machine.

Awesome work, it performs as it should however I do agree with Alasdair, it needs a cab otherwise it looks like a robot

You kidding, right?

[fresko]

Thanks for the nice comments!

Adding a cabine is a very good idea, but I'm not sure what kind of cabine I should make. The model is a compact excavator-style, so theoretical I have to make cabine over the whole structure. In that case I have to replace the valves. But because I think the valves are at well placed, is it maybe a better idea to build a regular excavator cab (a little cab on side of the boom).

What should you do?

You kidding, right?

I'm not sure if you sentence is a joke or not. In what way do you think the model isn't good? Instead of giving impolite comments, you can simply say how I can improve the model.

Greets,

You could have the vales at the bottom of the back cab window.

It would be cool if you could squeeze a motorized compressor into the machine too.

What Alasdair said would do the trick, and the compressor is a good idea too

And no, I'm not kidding otherwise I would not have said it if you do not like a model, at least offer some constructive criticism as to why you don't like it.

I will say it again, this is an awesome model Fresko, as it is nice and compact and well executed for the size, and is accessible for most people to build who have a relatively small Technic collection and pneumatics

No no, your model is cool, but not "awesome" (word often used wrongly here). Its a simple creation, functions and design are basic.

It's just tiring to see a lot of comments applauding creations quite banal, sometimes downright poorly made, etc.. This does not insite humility or the improvement.

So nothing personal, build and have fun.

It's all down to opinion, you may think it's a plain, boring creation, but to myself, and clearly many others, it is.

Very nice MOC and very good shape!

Robot crane!

No no, your model is cool, but not "awesome" (word often used wrongly here).

In the future, please try to be clear in your comments so as not to offend the builder. Debate on the usage of the word "awesome" is not the topic of this thread after all.

It would be cool if you could squeeze a motorized compressor into the machine too.

You name it cool if I sqeeuze a motorized compressor in it, but how would you name it if I tell you I motorized the whole model with 4 motors,

controlled via IR?

The motors are used for 1+2 Drive and Steer, 3 Turning and 4 Little pneumatic pumps (2). The pneumatic functions are still manual, with the valves on the back of the cabine.

Here you see 3 of 4 motors, The 2 drive motors and the turning motor. Note it can't turn continiously, trough the turntable are the electrical wires of the motors and 2 pneumatic tubes.

As you can see on the 2nd photo, I tried to hide all the wires much as possible.

And of course, a little video:

If I reach before 30 June 2013 100 Facebookpage likes (44 more on 14 June 2013) , I'll make instructions.

Tell me what you think!

It looks great,It looks much more like a real mini excavator.

[Nazgarot]

That is a very sweet little machine! I love the compactness of your solution, and the mix of manual vs IR functions. Nice build, and good improvement on the first version. Maybe a little white could freshen it up a bit?

[Someonenamedjon]

And the cab too!

[legomuppet9]

Great work, your changes have really improved the model

[bord4kop]

Now there 's a nice MOC!

Excellent work! Great, I love it! :thumbup:

[Kumbbl]

astonishing! :thumbup: :thumbup: :thumbup:
