Development and process

Here I started out by doing technical drawings and templates. By scaling up all measurements taken from a normal zip, and converting to the Borrowers scale of 14:1.

The next stage was to get the basic shapes machined out of chemiwood, ensuring their was at least 2 mm excess to sand out the machine blade, to ensure in a crisp and accurate finish

Next I experimented with heat bending chemiwood, to achieve the curve as shown in the image. This process worked, but was chemiwood was harder to bend as the material thickness increased. This process was a good solution. But not the quickest.
