Well, as much as anything is finished before final assembly.  

I drilled the 5/64" holes in the outer hinge pins, assembled the centre hinge point (bloody hard to cut a 2.5mm length of 1/4" tube for the bushing!) - got it all together and swinging freely.  

Only thing really left to do is source some sheetmetal screws and put an inspection hatch over the hole in the bottom skin where the trim servo is.

I sat the whole assembly upside-down and wiped the lower surfaces…

Last night I trimmed skins to size, deburred, cut out slot in trim tab spar for control rod and filed all the edges.

I'd seen other people use a Dremel tool to do the control slot - I don't have one (used to, think I lent it to someone!!) - but found that a step drill, used carefully and with wood clamped behind the aluminium, worked fine.  Even on the 0.016 skin.

I also made a doubler (just 0.016) for where the trim servo is riveted to the top skin.  

Still need some…

Had a good weekend - on Sunday I cut out & bent the rear skins (made them a bit oversize in span so I can cut the ends to fit), drilled and clecoed them to the skeleton on Tuesday evening.

Yesterday I had a couple of free hours, cut out the front skins and got one taped on.

I love front skins.   A simple rectangular piece of metal, give it a bit of a bend, and all of a sudden you've got a complete airfoil shape.  Fantastic!
