Many PDFs are done for chapter 2. The Californian engine is very different in form, so none of the PDFs from CH1 will work. The method is the same, the sizes are all different. Being such a lack of building from CH1, I've held back to give folks more time. Many are still working on Carter Bros and CPH.
Chapter 2 is a given, I have done a lot for it, just want to hang back a little.
