[[Has caption::Precious Plastic recycling machine| ]]

The shredder is the first machine we are building for the Precious Plastic project as all the other machines require small, somewhat uniform pieces of plastic as their raw material.

We should remember to take some photos with each step, so that we can put together a nice build log like this one in the end!

Materials

Armin got the laser cut parts and two flange bearings; they are in a box in the metal workshop.

Lukas contributed a piece of 27 mm (Schlüsselweite) hexagonal steel.

The motor we are going to was supplied by the CoMakingSpace and Johannes ordered a suitable gearbox.

We have a small selection of perforated metal plate (Lochblech) that could be adapted (cut and perhaps re-drilled) to be the "sieves" determining the particle size that comes out of the shredder.

Other materials include threaded rods and other metal parts that we should already have at the Space.

Tasks

The following tasks should be sufficient in order to assemble the shredder. If everybody is fine with github, we can also move this task list into a project on github. Please contact Martin if you want this to be done.

Number	Relevant Part	Task	Status	Responsible	possible tools
1	Shredder	Buy lasercutted parts for the shredder itself	Done	Armin	-
2	Shredder	Buy the hexagonal Steel	Done	Lukas	-
3	Shredder	Adjust the hexagonal steel	Done	Johannes, Armin	Metal Lathe
4	Shredder	Assemble the Shredder	Done	Flor	-
5	Shredder	weld the assembled shredder parts together	Done	Luzian	Welding Transformer
6	Shredder	make a hand crank for first tests	Done		-
7	Motor	we have a suitable motor(3kw by 1500u/min) and need a gear box - the [https://www.instructables.com/class/Large-Motors-Class/ "Large Motors Class" on Instructables may be useful	not started	who else would like to help?	-
8	Motor	Assemble the motor to the hexagonal steel	waiting for 7	who else would like to help?	-
9	Motor	install a safety switch (open when hands could get into the shredder)	waiting for 8	Johannes ,who else would like to help?	-
10	Framework	design the framework	not started (depends on 7)	who else would like to help?	-
11	Framework	buy the needed parts	waiting for 10	who else would like to help?	-
12	Framework	Assemble the framework	waiting for 11	who else would like to help?	Welding Transformer
