Components: Tail

The turbine tail hinges will be cut from 1/4 thick steel plate for the 8 foot turbine and 3/8 inch thick steel plate for the 12 foot turbine.  A steel dowel pin is welded in the top hinge plate at the location corresponding to a 10 degree offset in the unfurled position and the top plate has 90 degrees of travel counter-clockwise to the fully furled position.  The 2 pieces hinge on a stainless steel bolt with a silicone bronze washer between them.  The tail boom is welded to the Upper Tail Mounting Plate on the top hinge and will have a support running up from a lower hinge to about the middle of the tail boom.
