I am going to be machining Edgar Westbury’s Kiwi Mk II from bar stock. I thank Model Engineer Magazine for making the articles free to download. They were printed 60 years ago! I have captured the design in CAD and have made some modifications to ease my fabrication. I will not be using BA hardware, I moved the engine mount to the bottom of the engine so it will stand on its own and made lots of small modifications to suit CNC machining. I am starting with the front crankcase half, which will be machined in two operations, one from the back and one from the front, both using a ¼” flat end mill. I used my 3D printer to print the parts and identify errors in my CAD model, of which there were a few. I then used Fusion 360 to create the tool paths for my CNC router. My CNC router is home made mostly from MDF and performs surprisingly well.
