Until 2019 shipping small parts would always be cheapest by post.

Walt Murray's website with plans for windvane self steering systems
Thanks to Joern Heinrich the original pages with plans for home made self steering by Walt Murray, the American who inspired Sven to start building his own windvane self steering systems, have been kept. Now they have been rehosted.
Because there is a bit of lack in navigation options in the old website, use this page as a start. The link at the top of the pages below bring you back here.
