As referenced in our previous progress updates, we have been unable to access the Sturmey Archer hub directly. This was primarily due to it being a new version and the tools we had obtained being made for older versions of the sturmey archer. We contacted Sturmey archer and received information on the specific tool that would be required. A screenshot has been provided below. However, they also gave more specific instruction on how to destructively disassemble the hub. We will most probably proceed with the destructive route as we only need to understand its function.

Alongside of this, we have begun to make progress regarding our Solidworks model. We have developed a more complex model of the planetary gear set. This model has both a high and low gear set up. However, there is no direct drive or a clutch system in place to shift between the two. We will continue adapting this to add these features.
