Can Hardwood Shred ABS? Answered

I am thinking of making a prototype plastic crusher/shredder out of a hardwood instead of steel. Do you think that a hardwood would be able to grind a plastic such as abs into small pellets? If so what kind of wood would be best? What if I made a plywood out of hardwood to strengthen the grain? What if I just use nice plywood?

I have seen them done completely in wood and they work - but never for very long and never without constant care of the operator.

Keep in mind the stresses from crushing parts!
In general, the bigger you go in diameter with your crushing disks, the less problems you will have with the wood failing.
No clue where you are but there are really hard woods available - but in the long run it will be cheaper to go with steel.
Hardwood is not easy to work with and for your application you need to take care of the grain direction as well to prevent splitting.

Depending on how big your plastic rubbish is you might want to try a paper shredder that can handle DVD's and metal clamps.
