 Practical 2

For practical 2, we are tasked to do our literature review on cardboard and choose something to build that has at least 6 cardboard joineries. Of which our group chosen to do a water well. This idea was inspired by our LPS 1's water filter challenge and hence we decided to build water well. 

HOWEVER, our practical 2 morning started off with a FIREEEEE beeee boooo from one of the other workshops where we all had to evacuate and started 20 minutes late for that session and hence we were quite worried that we wont be able to finish our product. 

Lets go back to business.

Initially our cardboard well was supposed to look like this

But it turned out to look like this after our amendments during practical
Overall, we were quite proud of our product as it was successful and we used minimal glue gun.

Let's start to build 🔧

Materials that are needed:
  1. cutter
  2. scissors✀
  3. 2 piece of cardboard 
  4. rulers 📏
  5. cutting board
  6. brass fastener
  7. chopsticks🥢
  8. skewers
Step 1: Create a paper template with dimensions

  • 2 flange template (26cm x 26cm)
  • 1 square with centre empty (15cm x 15cm with a 7cm x 7cm cut out)
  • 2 circle with 1cm radius for storage of the string of well
  • 1 circle with 1.5cm radius for the stopper
  • 2 circle with 4cm radius for the wheel
  • 1 circle with 2.5cm radius for the bottom of the bucket
  • 1 rectangle with a measurement of 15.7cm x 5cm for the side of the bucket 

For template 2, the T shape to flange with a dimension of 26cm x 26cm. 
A 2cm x 3cm tab on both side of the outer square, one side of the rectangle and flange to create a slot and tab joinery. 


Step 2: Draw the paper template onto the cardboard and cutting out. 
Cut a slot at the other end of the flange to create a slot and tab for both flange.
Cut a slot at the other end of the rectangle for bucket as well.

Step 3: Cutting a base of 42cm x 42cm 

Step 4: Connecting the flange
1. Lightly cut the inner of the flange parallel to the flute for easy rounding.
This was the outcome when we cut it perpendicular to the flute and we had to redo.


DO NOT cut through to the other side and when connecting, 
the uncut face should face outside(not like the photo)
2. Connect the two flanges and make into 2 pillars. 
3. Punch one hole on each side of the pillar so that a chopstick can pass through it.
here's a photo of me and my sidekicks 



Step 5: Cut a slot of 3 cm on the flange to join the square and the pillar




Step 5: Connect the two pillars to the base
Cut 3 slot on each side of the flange to the base so it can be turned inwards to secure it.

Step 6: Connecting the chopstick to the pillar
1. Hot glue the two chopsticks together.
2. Wrap a layer of rope between the two stick(about 1.5cm length) to hide the connection and make it as a centre point.
For our case, we added a brass fastener to secure it more
3. Use a hole puncher and punch a hole in the centre of the 1cm radius circle to act as a stopper for the rope.



4. Place the chopsticks into the holes on the top of the pillars with the rope between the middle square box and cut off the excess chopsticks.

5. Punch a hole at the centre of the 1.5cm radius circle to act as a stopper. Glue gun it too one end of the chopstick (has to be near the pillar so it doesn't move around)

Step 7: Making the wheel
1. Punch a hole on both of the 4cm diameter circle and glue gun it together. 
2. Insert skewers to act as handle and trim off the sharp edges.
3. Hot glue it to the open side of the chopstick.

Step 8: Making the bucket
1. Join the two end of the rectangle together.
2. Punch 4 holes diagonal to each other on the top.
3. Punch another hole at the lower half and use a brass fastener to secure it.


4. Glue the the walls of the bucket to the base of the bucket.
5. Criss cross the chopsticks and trim off the excess part.
6. Tie a knot with the rope between the chopstick within the bucket.
Step 9: Decorate!!!!
This is what it should look this. 
ITS SO HARD
can we skip to the good part? Ah, ah ah ah
one two three four

Overall this project was a success. Here's a photo of us with our product and also a video to show how it works.



These are the six joineries we used:
  1. Slot and tabs
  2. Flanges
  3. Skewer
  4. Holes and fastener
  5. Score bend-pillars
  6. Smooth bend-bucket
Reflective journal:
Through this practical 2, one main takeaway is that cardboard is not a child's play and it requires the knowledge and skills to make a good cardboard product. When we were cutting the pillar, we actually did it in a way that was perpendicular to the flute hence it was hard to fold and make it to a nice bent. However, remembering Dr Noel mentioned, we should always cut parallel to the  flute and we though of trying it and it worked as it already provide guiding lines so it will create a smoother hollow tube. 

When we did our joinery for our slot and tabs, we actually found out that we might not have enough knowledge on how we should cut the tab and the dimensions of it, and hence we cut a straight rectangle. After analysisng one of the product done by a cardboard maker, we realised their tabs are not just rectangles but more like a hexagon and this provides a tighter and secured fitting.

As we were trying to find ways to secure the pillar to the base, one of my teammate suggested to cut tabs on the base and slot it inwards so we do not need to glue, and that was actually a good idea.

One of the things I learnt was tabs should be placed at the edge where there is a turning or bent and not just anywhere. This knowledge can be useful for when I start prototyping my chemical product where we need to use 0 glue. 
 
Another thing I learnt was to not cut chopsticks with scissors as during the practical, I broke the scissors.
