I thought I had too many projects on my hands... The 'dutch ebay' (Dutch language alert!) has an awesome object offered: a home made hovercraft.
It uses an Citroën 2CV6 flat-2 engine to create the volume of air below the hull. Seller asks 400 euros for it but it's not yet finished as the steering-flaps have not yet been installed.
Too bad the seller doesn't post a video, pretty curious how/if it runs!
