This week time in the workshop has been spent sanding. The main spar caps, rear spar caps, inner leading edge, and aileron spar all needed sanding to final size to blend in with the ribs top and bottom. I made up a sanding block long enough to sand across four ribs at a time by cutting open a sanding belt and gluing it to a length of flat timber. Using this it was possible to blend in the
joints without risking sanding dips into the timber between the ribs but it is slow progress and hard work. As at today the wing is complete except for the upper rear spar capsticks and upper aileron spar so I'm about 80% complete. The bottom picture shows the way the upper surface of the root rib and
inner leading edge have been tapered to allow the skin to glue in place.
