Lots of areas on the wings are uneven by design. When I put the fabric on those areas will create ridges that won’t look that good. I decided to glue on some “ramps” so the transitions are smooth instead of abrupt.
I started by stapling a 1/16″ strip to a board.
On the edge of the board I stapled some 1/16″ plywood material.
Placing the first strip on the router bottom puts the side at an angle. Using a flush cut but the ramp was routed onto the plywood.
I took the long strip of ramp material and cut it into 1/4″ sections.
These small ramps are glued onto the ribs wherever an abrupt change in height exists.
Whenever I mix up some glue for something, whatever is left over I use to glue on some ramps.
