MAKING THE FINAL PROTOTYPE FINAL
Weighing the PVC pipe.
Measuring out the measurements for the bends.
Compacting the PVC pipe with sand.
Bending the pipe into the shape.
Bending the pipe around the jar and lining up the pipe with the measurements.
I pulled the pipe around the jar to eliminate the pipe from compressing together.
Bending both the ends.
Using a clamp to clamp the jar down onto the table.
Cooling down the pipe with cold water.
Finished bending the bottom curves.
Measuring the second pipe.
Heating up the second pipe.
Using a bag of sand to help hold the pipe in place so it wouldn't move.
Close up view of the bend.
More bending.
First bent piece.
Two pieces complete so its time to bend it again for the seat.
Measuring the height of the chair to bend it.
Measuring the height of the chair to bend it.
Bending the pipe in the other direction for the seat.
Cooling down the plastic.
Bending the second bends required two people because one had to hold while the other person bend the piece into place. Thanks mum!
Finish the bending in the jig.
All the pieces have been bent into place so now I need to cut the legs down.
Weighing the piece.
Measuring the T shaped joiners of how far the pipe goes in.
Measuring the distance to cut off the unneeded parts.
Cutting the legs to the required length.
Weighing the pieces. It weighed about 800 grams.
Adding the T shape joiners with a small piece to help the stability.
All pieces have been put together to see how it came out.
Weighing the chair so far.
This is how many more pieces i can use before reaching the 2 kg mark.
Top seating section came out way too small so I had to get feedback from Ian.
Ian suggested to add in a 2 bracing section from wood going a cross the 2 middle pipes, then add a piece of wood on top for the seat.
Marking out the 2 holes for the pipe to fit through.
2 holes marked out.
Cutting out the 2 holes. I decided not to go with this idea due to not weight issues.
Marking out the measurements for the seat.
Cut out a rectangle for the seat. Sanded the edges so it's round. This piece of wood weigh around 400 grams which i was hoping for it to be a lot less.
Glue specific for PVC pipes.
Gluing all the pieces together.
Glued the chair together and using clamps to make sure the middle section is tight.
Because of the weight issues once the top seat is added in, I have decided to either use rope or threaded steel rods to stop the legs from going in the opposite direction once someone sits on the chair which will hold the chair in place for structure and balance.
