3th test of mini DIY shredder with Sonyericsson
Published on March 11, 2017
News about mini shredders and Filamaker system are here :
You can see the safety coupling in action. I have purposely set the uncoupling strength down to be sure not to damage the blades, they are in this model from normal steel and not from tool steel like in next model. This model was made only to test the geometry of blades.
If somebody want i can crush some old siemens and nokia to make the blades done 🙂
4th Test .
