Preconstructed rotating blade.

13 Fixed blades

14 Spacers

2 Threaded Rods

4 Nuts

Instructions: Thread the spacer and fixed blades onto the rods in alternating order starting with the a spacer. Place the assembled blades onto the narrow box with the bottom lip aligned with the bottom of the fixed blade assembly . Line up the rotating blades with the fixed blades oriented so the rotating blade rotates into the curved side of the fixed blades.

Étape 5 -

Now slide the side plates on one at a time keeping the front sides together. Add the nuts to the bolts, not too tight. Flip the assembly on its side. Slide the thick box into place on the front.

Orient the blade and side plates as seen in the picture.

Slide the bearings onto the shaft, with the bearings facing out.

Make sure that the extra hole (double hole?) is facing the back side.

Étape 7 - Shredder Box Construction

Parts:

Preconstructed box (narrower)

Preconstructed box (thicker)

*ORIENTATION: Facing the side plate with the longer shaft, the side with two holes in the upper left corner is the back of the shredder box.

*ORIENTATION: The preconstructed boxes have a top side with 1 hole, and a bottom side with 2 holes.

Place the narrower of the two pre-constructed boxes inside the two side plates. The narrower box has a small lip, that should be on the bottom, and facing towards the knives.

The thicker box mirrors the narrower box (one hole facing up) Tabs on the preconstructed boxes will slide into holes in the side plates.
