Step 1: Body Base Plate
1) Used materials :
- MDF (A) : base plate 900*500*15 mm
- MDF (B) : 3 shelfs 500*170*15 mm
- MDF (C): beam 40*500*15 mm
- Wood connectors
- Nuts and bolts
- Screws
- 4 wheels
2) Tools :
- Saw
- Drill
- Wood glue
3) Saw a corner off :
- MDF (B) : 15*40 mm => 15 mm in width, 40 mm in length of 1 corner.
- Apply this step for all 3 pieces
4) Construct :
- Screw and glue MDF (C) on 1 side of the base plate MDF (A)
- Line out the MDF (B) shelfs over the length of the base plate MDF (A). A schelf on every 22.5 cm.
- Screw and glue the shelfs (B)
- Reinforce the shelfs with wood connectors to the base plate (A)
- Attach the wheels to the plate ( 80*80 mm from corner)
Step 2: Right Body Plate (wood)
1) Used materials:
- MDF 100 x 120 x 1,5 CM
- 4 x hinge
2) Tools:
- Drill
- Drill 46 mm & 32 mm
- Screws
3) Saw the right body plate:
- MDF, saw the right body plate in the next dimensions: Height base plate – highest peak = 100 CM Height start mouth till base plate 70 CM, distance to rear end 120 CM Height back 75 CM
4) Drilling 3 holes:
- Drilling 3 holes of 46 mm at the top of the plate. measured from the bottom right, straight up and then sideways. See the picture above.
5) Drilling 6 holes:
- Drilling the 6 other holes of 32 mm in the plate. measured from the bottom right, straight up and then sideways. Distance B-C = 13, distance A-b = 9. See the picture above.
6) Saw the 4 doors:
- Line out the 4 doors on the bottom line. 16 x 16 CM.
- Screw them back in with hinges.
Step 3: Left Body Plate (perspex)
1) Used materials:
- Perspex
2) Tools:
- Saw
3) Saw the left body plate:
- Saw the right body plate in the next dimensions:
Height base plate – highest peak = 100 CM
Height start mouth till base plate 70 CM, distance to rear end 120 CM
Height back 75 CM
The same as in step 2.
Step 4: Front Plate (wood)
1) Used materials:
- MDF 530 mm * 790 mm * 15 mm
- MDF 60 mm * 740 mm * 15 mm
2) Tools:
- Saw
- Wood glue
- Screws
3) Saw the MDF plates in the right dimensions.
Step 5: Polygonal Holders (right)
1) Used materials:
- 4 x MDF (100mm*100mm*15mm)
2) Tools:
- Wood glue
- Screws
3) Saw 3 polygonal holders with in the middle a hole diameter 46 mm and 1 with diameter 32 mm.
The holders are in the places where you can not rotate the axes.
Step 6: Polygonal Holders (left)
1) Used materials:
- 12 x MDF (100mm*100mm*15mm)
2) Tools:
- Saw
- Screws
3) Saw 6 polygonal holders with in the middle a hole diameter 46 mm.
Saw 6 polygonal holders with in the middle a hole diameter 32 mm.
Wherever there are holes or holders placed at the right side, there are holders placed with the same dimensions on the left perspex side.
Attach the holders with screws to the perspex.
Step 7: Hollow Profiles for Peripherals
1) Used Materials:
- 4 x insulation foam (or others)
2) Tools:
- Contact glue
3) Cut off 3 pieces (length = 200 mm and a diameter of 80 mm)
Glue the profiles onto the perspex side and the MDF side at the correct dimensions.
Step 8: Axes
1) Used materials:
- 3 wooden cylinders (length = 540 mm and diameter 40 mm)
- 3 wooden cylinders (length = 500 mm and diameter 40 mm)
- 5 wooden cylinders (length = 650 mm and diameter 25mm)
- 1 wooden cylinder (length = 500 mm and diameter 25mm)
- The axes can be covered witch all kinds of materials: we use a paint roller, gloves, insulation foam and a wooden plate.
2) Tools:
- Glue
- Screws
- Drill
3) The foam, paint roller, gloves, PVC and the wooden plate are glued or screwed to the axes.
Step 9: Handle Wheel
1) Used materials:
- 3 x MDF plate 250mm*250mm*15mm
- Standard wooden handle
2) Tools:
- Saw
- Sander
- Screws
3) Make a circle witch a diameter 220 mm. Use a saw and a sander to become the correct dimensions of the circle.
Screw the handle to the circle.
Step 10: Teeth and Tongue
1) Used materials:
- MDF plate 520mm*110mm*8mm
- MDF plate 520mm*100mm*8mm
- Flexible foam
2) Tools:
- Belt saw
- Sandpaper
- Glue gun
- Box cutter
3) Saw the shape of the teeth out of the MDF plate. (see image for dimensions)
Finisch with sandpaper.
Cut out a tongue from the flexibel foam by using a box cutter.
Glue the tongue to the lower teeth.
Step 11: Assemble Body
1) Tools:
- Wood glue
- Screws
- Drill
2) Screw and glue the left body plate(perspex)and the right body plate (MDF) to the base plate.
Screw the front plate to the left, right and base plate.
Step 12: Assemble Other Components
1) Tools:
- Screws
- Glue
- Drill
2) The axes are disposed between the holders and thrue the holes. (blue on the image)
The wheels are screwed and glued to the axes of the conveyors. (green on the image)
The teeth are screwed and glued to the body (yellow on the image)
Step 13: Conveyors
The conveyor belts are tensioned between the thickest axes.
We use bicycle tires as conveyor belts.
Step 14: Make Back
We stretch an orange rope between the two sides as reinforcement.
On the ropes we put a cardboard.
