Over the last few days I've continued working on the elevators.  Drilled all holes and removed skins from skeleton.

After some measuring and muttering, I carefully cut out the trailing edge of the port rear skin where the trim tab goes.  Reattached the skin and mounted the tab and hinge, drilling through the skin, hinge and tab spar.  Turned the elevator over and drilled the bottom skin to tab spar as well.

Trim tab looks good in the slot and moves freely.  The side gaps are 2mm and the TE lines up nicely with the elevator TE.

I made a couple of 0.025" doublers for the narrow sections of trailing edge either side of the trim tab - being made of 0.016", the skin is prone to creasing there.  These doublers fit under the skin and have 2 rivets top and bottom through skin, doubler and rib.

My brother in law Jim (electrician) came down yesterday so I got him to solder the wires from the trim tab servo to the 19' cable that goes through to the instrument panel.  Very neat job and colour-coded heat shrink over the joins.

Located the servo to the upper skin and drilled the mounting holes, also cut out the inspection hole in the lower skin.

Planning to get back into it tonight, there's still a heap to do before riveting!
