Section 20 Bottom Wing Skin complete

The last part of this section was to rivet the win skin to spar and ribs. This was very demanding work. But as usual, it's starts out very difficult and becomes easier as one get the hang on it. All was done solo😎

Total time for this section was 80 hours including skin preparation, aileron and flap fairing, pitot mast installation, and skin riveting. 

Left side. It's shiny😁

Right side.
To get better access I raised the whole wing cradle
by approx. 50 cm (20 inch.)

The start. Right side.
I struggled a lot to set the rivets on the rear spar (top in the picture)
in the beginning. So I decided to uncleco the J channel in the middle
to get better access while doing the rear spar and the two rows on the rib.

I used my Vividia inspection camera together with
an iPad to check rivets. This was very handy.

I made myself a little work table for the rivet gun, rivets etc.

The outboard large skin is ready.
