HAWT DIY Vert. Axis Rotary Contact 2 leads

This is my second attempt at a robust rotary contact. Commercial rotary contacts start at around $50 and go up fast so I decided to experiment with this design.



A key component of any HAWT is a good rotary contact, I have learned over the years that making things small and compact is only necessary when you don't plan or leave yourself enough room. This was a definite success; after I decided to use commutators from an electric motor. The vert. bearing pack is above.




The Rotary Contact if safely covered by the mounting tube, any rain water that seeps into the tube will not be a problem.
