Yes, it's back!
Your work is hugely inspirational for me and has spurred me on to do similar things. I am currently working on a Shorts Sperrin in 1/72 (still a big model for my standards).
I have done my cad model in Blender but have since transferred to Solidworks as blender is a bit limited as a cad program. My parts are then milled in my Shapeoko 2 CNC from a medium density modeling board. What type of CNC are you using?
I have a work in progress thread over at britmodeller if you are interested.
