Looks good!
The pedal shredder needs a flywheel though, that would make it smoother and easier to pedal.
Vernon beat me to it!
Watch your fingers - the shredding bit definitely needs a guard.
I worked in a factory between school and poly. It made moulded and extruded products from plastic and inevitably there was a lot of scrap plastic to deal with so we had a giant plastic shredding machine to chop the waste into small, manageable pieces.
I think the idea was to chuck some plastic in, then stand back and switch the machine on. In practice, that was too slow so when I used it, I just left it powered up and fed the plastic in as fast as the machine could chomp it.
One day I was told to shred a huge quantity of rubbery plastic strips. They had been designed to be used to hold cable runs across floors, but were defective in some way.
I powered up the machine, which was so powerful that it sounded like a helicopter ready for takeoff. As usual, I fed the scrap in as fast as the machine could cope with it. Despite the power of the beast, if this were done too quickly, it was still possible to jam it up.
I had fed too in much plastic and the blades slowed right down as they munched away at it. I was still hanging on to the end of a length when the machine finally cleared the blockage and went back to full speed, grabbing at the plastic and yanking it in. The end of the plastic strip somehow got wrapped round my wrist and started pulling me in!
Fortunately, the machine stalled again and I was able to kill the power before I ended up in the blades.
Since then, I have heard of many cases where people died in such incidents -
example.
One lad that I worked with almost had his arm torn off when it got caught between 2 rotating rollers which were like a giant motorised mangle.
The things I saw and experienced in my factory jobs made me very aware of the need to take work safety seriously!
