Picture of Cardboard chainsaw

Hi, this toy chainsaw can be used on several occasions since trash movie to a fantasy party. It operates very simple: a button is pushed on the handle where it is held, which connects the engine and causes current to run. It was made with recycled materials that I had at home.
I hope you enjoy.

Step 1: Materials needed

- 04 gears of a bicycle rear derailleur gears (screw, inner cylinder and the two caps, each);

- More than 02 screws to the inner cylinder;

- About 75cm bike chain (run);

- Slatted wooden box *

* I used 3mm balsa wood as he had at home. Can also be used thick cardboard (0.5 mm) which is much easier to find.

- Cart with a gear wheel, as figure;

or

- Standard servo modified for continuous rotation (see the internet how to make this change);

- 2 hangers (servo arm as shown);

- 2 small screws or glue to attach the hangers.

- 1 support for four batteries

- 1 normally open switch

- Hot glue, glue, ruler, pen, pencil, etc ...

Step 2: Preparing the servo

After turning the servo to continuous rotation, solder two wires directly contacts the engine, by-passing the electronic circuit. I used the wire itself the servo, taking care to leave a tip of three wires which were originally linked to later be able to use again as a servo. That done, simply reassemble the servo. A good tutorial on how to put the servo continuous rotation:

Combine the two crosses as figure using screws or gluing tight.

The crosses were selected because they have a center that fits mayor, allowing an optimal alignment between the servant and gear.
Umm, is there a video? I'm sorry that I find this hard to understand but it would help. I'm just a 13 year old trying to mess around and just try to get it to work. Will a video be up soon? Or could you link me to the video? Thanks!

I think it's a good instructable in the design and planning and I especially liked the picture by picture detail of the build through the steps, but sadly, the sentence structure and word choices show the limitations of the translation software. I run into the same issues with user's manuals for some of the milling machines I use at work.

Thanks for the comment. Glad you liked the step by step.
I promise to improve my English, as far as possible.
This would be perfect for cutting down the cardboard tree in my backyard.
;-D

Excellent work. It appears to be a left-handed chainsaw though. Even more sinister that way, though.
