How I'm Building and Test Flying a Cozy MKIV
(My Second Homebuilt Plane)

So. The Instruction manual and plans have chapters, and the first chapter in which you build part of the plane is Chapter 4. I'll organize this by chapter, starting with Chapter 4, but first I'll show you the spacious quarters (my basement) in which I started building this plane, and the tools and implements I've accumulated to do so.  Around about Chapter 21, I moved to a new house with a 2 car garage.
