Recycling a PET bottle to a 20m long thread.
You can recycling PET bottles, beer cans and similar round shapes objects (junk) to thread.
Basically recycling means: to treat things (junk) so that they can be used again.
Thread is a raw material for production, usually for sewing or making fabric or some similar things.
PET is very strong material. 1.5mm PET thread can hold 5kg at least (I don't know exactly).
A 2l PET bottle can be recycled to 3mm thread 20m long.

Step 1: Material and tools

Here is a link to some great pictures of the gizmos that cut these very thin strips. I was all ready to order one but they are not allowed to export from Brazil.

Can any of you clever guys figure out how to make one from the pictures and videos on this site?

I would love to have a few of these. (I'm a craft teacher in Australia).
I followed the lik to the hand tool that you can use for filiment making does anyone have a picture of a real one and a drawing. Can't be that hard to make. I used a gismo similar in concept to trim leather for belt makingback in the 1970's sparkie
could be usefule stuff, but it is not string it is ribbon if you build a jig you could flame the edge making it safe. You could slice off a finger using a power drill, so USE GLOVES. I have usedpieces of soda bottle as temp hinges and connecter materials (like the stuf they use in building trades to connect wood set up in a T configuration. nice idea though great instructable

Is there some way of automatically cutting the bottle?

That looks great and simple, but I don't see any instructions that explain how it is built.  I can't quite seem to wrap my mind around it.  Are there instructions for it somewhere?
You could do it with a lathe. Mount the can in the chuck, box cutter knife in the toolpost, set the machine for a low speed and a thread cutting pitch of whatever you like.

I think I would just heat up the bottle and pull it through a small hole in a block of wood.

Good instructable :)....but for that aluminum cable? I think it would cut your fingers :S... because of the sharp edge that is left after the scissor cut... have you tried it already?
You can twist several threads together, similar to making tough rope, and get a strong aluminum cord out of the deal - the twisting process tends to tuck in the sharp edges (you have to go slow to prevent snaps though). If there are any sharp segments left afterward, take a heavy leather glove and some rough sandpaper and run it up and down the cord a few times. Soda cans make great binding wire.

Hope that helps

Not really. The confusion comes from not having read step 6.

you could connect more than one bottle by melting the two tips of the wire together

hi thanks a lot
can I ask you, what will you do with it ?
it's interesting but ... what's the need
the thread seems too big and square :s

someone have a plan for making this one ? >>>
Well, I'm not sure what the author intended - but I know there are people working on using PET as feedstock for a Reprap-style 3-D printer. Generating PET filament is crucial to that task.
