Étape 3 - Table Construction - Legs
Tools
XX Socket Wrench
Screwdriver
Parts
4x 8080*600mm
2x 8080*1200mm
4x Side Plates
32x + 13x T nuts
32x Washers
32x M8x16mm Bolts
Steps
- Lay one 1200mm beam horizontally in your workspace. Add a 600mm beam perpendicular at each end, forming a staple shape. (see image 5 for final shape reference)
- Using 8 total washers, slide 2 at a time into each rail at the corner, approximating the hole pattern on the side plates. (image 2)
- Using a screwdriver to position the T-nuts, add an M8x16 Bolt and washer through the side plate into each T nut. (images 3 and 4)
- Secure with a socket wrench. Repeat on the other side of the 1200mm beam.
You now have a staple shape. Repeat.
It is important to now denote which one of these will be your front and which will be your back. Just pick.
- On the BACK staple, top side, inner track, add 8 T-nuts for later use. [image 6 shows what they'll hold in a future step]
- On the Front staple, top side, inner track add 5
*make sure these stay in place as you rotate the leg pieces and continue to build in following steps.
Étape 4 - Table Construction - Side Joints
Tools
1/2" Socket Wrench
Screwdriver
Parts
2x 8080*520mm
4x Corner Plates
32 + 12 + 4 (48x) T nuts
32x Washers
32x M8x16mm Bolts
Steps
- Stand one leg unit upward, so you can see down the 1200mm section. Slide 4 T-nuts total (2 in each rail) up to the corner joint. (image 2)
- SPECIAL STEP: on the 1200mm beam, opposite side from where the side plate was installed - Slide 2 nuts into each of the rails. These will be used in a future step. Repeat on the other 1200mm beam.
- Attach the side plate (image 3) using 4 M8x16 Bolts with 4 washers.
- NOTE: the 45° side should face the "bottom" of the eventual table.
- Repeat on the remaining three 600mm legs.
- NOTE: ensure that each corner plate mirrors each other across the 1200mm beam axis. They should be facing the same direction and away from the side plate from the previous step.
- Slide 8 total T-nuts into a 520mm beam. They should be split in half, 4 at one end, and 4 at the other. (Image 4)
- SPECIAL STEP: On only ONE of the 520mm beams, add 4 T-nuts, 2 in each rail on the opposite side that you used for Step 5. This will become the inside of the right side rail.
- (image 5 left) On the top of this rail, slide 2 more t nuts in the outside channel.
- (image 5 right) On the left side rail, slide 2 nuts on the top surface, inside channel.
- Combine the two "staple" sections by adding the 520mm beam (pre-loaded with T-nuts) using the same M8x16mm, washer combination as before. (image 5)
- Repeat on the other side. (image 6)
You should now have a very solid table base!
Étape 5 - Table Construction - Side Braces
Tools
1/2" Socket Wrench
Screwdriver
Parts
2x 8080*520mm
8x Brackets
16x T nuts
16x Washers
16x M8x20mm Bolts
*A quick note about bracket orientation. In image 2 you will see that the brackets are not the same on both sides. Here we have flipped one, so you can see the difference. One of the holes sits atop a raised lip, while the other is flush. The raised lip hole is closer to the brackets outside edge. The flush hole is farther from the outside edge. This matters for order of operations. When installing, you must install in the flush hole first, and the hole with the raised lip second. If you do it in reverse the bolt will block access to the other hole. :)
Steps
- Slide 4 nuts into the 520mm beam (2 in each rail).
- Attach the 4 brackets loosely using M8x20mm bolts and washers. (image 3)
- Note the orientation of the holes. All 4 bolts should go in flush holes, not raised-lip holes. (figure 4)
- With the table flipped on its end, position the 520mm beam in place, and slide 2 T-nuts in the rails to meet the brackets. Secure with same M8x20 bolt washer combo.
- Repeat this process on the other side of the 520mm beam.
- Repeat steps 1-4 on the opposite side of table.
Étape 6 - Table Construction - Center Struts
Tools
1/2" Socket Wrench
Screwdriver
Parts
1x 4080*520mm
1x 4080*455mm
16 Brackets
20x T nuts
32x Washers
32x M8x16mm Bolts
*Construction note: Until the very end, keep ALL of these bolt joints LOOSE. They will need to slide around to get everything in place. Once the location has been set, then you can tighten them down.
Steps
- Insert 4 T-nuts (2 in each rail) on one side of the 520mm 4080 (image1 )
- For both beams, attach brackets (using the flush hole) at all 8 corners. (image 2)
- Arrange the beams so the 520mm beam is vertical, and the 455mm beam is horizontal, intersecting near the middle of the 520mm beam on the left hand side.
- Insert 3 t nuts into the top rail of the 455 horizonal beam, and 2 t-nuts into the top rail of the vertical beam
- Loosely attach the horizontal beam to the vertical beam. (images 3 and 4)
- Remember all those T-nuts we hid in the frame in step 4? Now we are going to connect this sub-assembly to them.
- Place 4 bolt/washer combos at each of the 3 locations designated in image 5.
- Drop the sub-assembly into the table frame, and loosely connect the brackets into the pre-loaded T-nuts
- This is easier with 2 people.
- You only need 1 bolt at each of the three locations to hold the weight of the sub-assembly.
- After those first three bolts are in, you can easily go back and connect the others.

22x 1/4" spacer
22x thin spacers
- Identify each of the twelve unique blades by the small cut markings on their interior.
- Blade #1 will have 1 mark. It is important to note where this mark is, as this will be our Reference edge.
- Blade #2 will have a 2nd mark rotating clockwise. The reference edge still stays at the top.
- Blade #7 will start a new pattern of two markings per face, again continuing clockwise.
- Screw one of the nut halves to the short end of the shaft.
- Label one of the sides of the shaft as a reference face.
- Now slide Blade #1 onto the shaft ensuring that the teeth will rotate towards the center of the box when installed and that the reference edge of the blade matches the reference face of the shaft.
- Follow this blade with 1 large and 1 small spacer.
- Repeat this for the other blades 2-12, then beginning again with 1 and ending on blade 11.
- Do not install spacers after blade 11. Instead cap the entire shaft with the other nut half.
- Set aside
Étape 16 - Shaft Assembly Preparation (long shaft) and install
Tools
Chain, nylon strap
Parts
2 Nut halves from step 12
1130.02. Shaft 1:
22x 1130.01 13-Teeth Blade
24x 1/4" spacer
24x thin spacers
Steps
- Add a nut to the short end of the shaft.
- Add both large/small spacers first.
- Again choose a reference face on the shaft.
- This time, each blade will be rotated one face away from the previous reference edge.
- Image 2 shows how the marking travels up the spiral pattern.
- Repeat by adding blades and double spacers until all blades are placed. ending the shaft with a double spacer.
- Add the 2nd half nut.
You now have 2 complete shafts ready to drop into your shredder box. This is very difficult to do alone, and can also be hazardous due to the heavy weight and sharp edges.
To install:
- Mesh the two shafts together outside the box.
- With a partner, lift the double shaft assembly as far into the box as you can, leaving room to escape your hands.
- Thread a chain, rope, nylon strap, or anything that can drop below both shafts and that can serve as a handle to lift the assembly up and into its final position.
- Unthread the rope assist seat the shaft nuts into the openings in both ends of the shaft box.
- Replace pieces 1110.08 and 1110.09
Étape 17 - Bearing Prep
Tools
Bench Vise
Angle Grinder with flap disk
(Digital Caliper helps)
Parts
2 Bearings
Steps
As is, the bearings and gears do not fit inside the shredder box. about 1/8" of an inch of material must be removed from the bearing sleeve.
- Measure the depth of the sleeve before grinding. Use the thumb screw on your digital caliper to lock this distance.
- Using an angle grinder, remove the necessary material.
- Recheck the distance, ensuring you've removed at least 1/8".
