Hi Guys,
After reading a lot about the precious plastics project and about shredders in general (which i want to start with building), i keep wondering why the design of the shredder blades differs so much of shredders in general found on youtube.
Can anyone tell me why the shape of the blades is this way? (thickness as well as shape) ?
And last but not least, why one axis? besides costs/complexity offcourse:)
Just thinking everything well through before buying parts!
Thnx
Anybody? Please share you thoughts folks! 
Hi @davehakkens,
Thanks for clearing that up. Did the blades bend in your experiments with using 5 mm thickness steel instead of 6?
There’s some other topics where people are wondering the same. And I haven’t gotten through all of them but in the ones I did, I couldn’t find an answer either.
Did you ever find out? I’m looking at the plans and am wondering about those thicknesses. Why are these different? Does anybody know?
Did you find any other shapes of blades?
Regarding the axis I guess you answered yourself. I would think it would add too much to the complexity.
