3. We used MDF as the material for platform. Medium density fibreboard is more strong than Luna polywood. Therefore, we used it could increase stability for the whole structure. To solve connections between strips and platfrom, we made card slot on platfom. In our propotype 1, the poor connections between strips and platform could only provide stability on vertical but not horizontal. Now in our new propotype, by inserting strips into the card slot, strips will not shift easily.
4.From the test in prototype 2, we could find construction methods mentioned above are workable. So we decided to apply those methods in final detailed model. Last but not least, there is still one thing need to concentrate on that timber veneer is crisp sometimes. So when we are assembling strips, we must be patient.
