I had never heard of Calotype photography prior to reading this book. I haven't completely read the entire book, but my current understanding of the Calotype process is to produce a paper negative using a wet plate type process. This seems to me like it would be more cost effective to learn the basics of camera construction and darkroom chemistry than jumping right to collodion.
So my immediate goal has shifted toward Calotype photography. I plan to build a camera, including film holder and lens. All of the instructions are in this book. I will document my progress along the way.
That brings me to the present. I have purchased the materials needed to begin construction of the wet plate film holder. It will be an 8x10" size designed for use with wet paper negatives of the "whole plate" size of 6-1/2" X 8-1/2". There are charts in the book that explain why, but you'll need to buy the book to really get into the science of it.
So here's my pile of wood.
