Not quite as fancy as the trains etc in the link but this is what I started making about 4 years ago (!). It's my own design and should look like a Spitfire when complete.

Cutting out some bits on the old cnc machine:


I've since gone through 2 cnc machine upgrades since these photos were taken and various workshop improvements. The CNC side has dragged me in - so much so that when I showed some pictures of my current CNC machine to a friend recently and he said what do you make with it? I had to pause and think a bit, before remembering it was originally designed to make balsa and liteply bits for RC planes.
