Sliding hinge mechanism

Today was spent fabricating the hinge mechanism for the winding gear cover, updating my aviation database and shopping, First I had to make a double hinge support block to attach the winding gear cover to the jib block support frame, two 1.18mm holes are drilled though the support block for the pivot rods.

Next two channels are cemented to the underside of the winding gear cover to allow horizontal movement of the support block when the jib is raised. Finally a length of rod was glued though the upper hole in the block to engage in the channel.

A little trimming of the lower rod is needed and I am very pleased with the way the action works.

Well that is all I propose to do this year so to all have a very happy new year.
