This has been my project for a few months now. This is going to be my 6 yr old son's Christmas present. My son discovered lego shredders probably a year ago and has done his best to imitate and create his own with his duplos, but could never accomplish more than creating a "crusher". Seeing his passion and drive, I wanted to reward him with something I knew would just blow him away. So, I've been watching lego shredder videos, doing research, buying miscellaneous gear, bushing, axle, and brick sets trying to accomplish the effect of shredding, not just crimping as most lego "shredders" do that you find on you tube. I got some help from the maker of The Muffin Monster youtube video who advised using the gears you see in this video. I'd originally thought they'd work, then I saw a video using them which kept jamming so I'd steered away from purchasing these. After The Muffin Monster maker's advice, though. I purchased some and I'm glad I did. I only have full bushings (the orange things between the gears) and not half bushings. Half bushings would put the gears even closer together and I think improve the shredding. Here are the things I use in the creation of this lego shredder:

Legos Brick Set 6177
Lego XL Motor
Lego Battery Box 8881
Size 12 Axles (4 are used here)
Four 24-tine Gears
Several Half Bushings
12-15 Full Bushings (I recommend using half bushings and about double the number)
12 U031A Propeller Blade "Gears" (although I don't know if they technically are gears).
8 Lego Bricks with Holes (I can't recall offhand how many holes each brick has, but you might be able to see in the video).

I think that's about it.

You will need a LOT more long bricks to stabilize the whole unit more than mine. You will also want some pieces I don't know the name of (they insert in the holes of the motor and some bricks) and you can attach them to other bricks to stabilize the motor and keep it from spinning.
