Have you always wanted to build your own wings from foam materials like EPP or XPS? Over at rckeith.co.uk, you can find a highly detailed ebook available for free that guides you step by step through building your own 4-axis CNC machine. With it, you can cut all kinds of wings from foam — tapered, with or without twist, with ailerons, and more — and even fuselages.
The machine can be built without extensive prior knowledge. Anyone who is motivated and has a bit of hands-on skill can get started without any issues. The hardware costs less than €250 and consists of simple, commonly available parts such as plywood, drawer slides, and threaded rods. You can find the instructions and all required materials here:

To make things even easier, we’ve created a 3d-printz version of the hot wire cutter, where many parts are 3D printed and assembly becomes even quicker and more straightforward. We’re happy to provide the 3D printable parts as well as the plans here for free.
For our version of the CNC machine, you will additionally need:
– 15 mm plywood sheet according to the plan (see images)
– 15 mm wood screws
– 4x Nema 17 stepper motors
– 4x M8 threaded rods (1 m)
– 4x M4 nuts
– 2x 608 bearings (not strictly necessary)
– Arduino board (see rckeith.co.uk)
– RAMPS board (see rckeith.co.uk)
– Power supply
– 600 mm and 450 mm drawer slides
– 0.4 mm NiChrome wire
– 4x flexible couplers for Nema17 to M8
– 12V fan
