Construction 

Wing Skins 

 

Each wing bottom skin consists of two laser-cut pieces: 
forward, center and aft. Gently clean up the mating 
edges of the pieces with 220 grit paper on a sanding 
block.   

 

Lay the pieces of a wing skin on a flat board or table, 
with the outer surface up. Run a length of masking tape 
along the join lines. Turn the assembled skin over, 
bend the joints open, and run a bead of aliphatic resin 
or wood glue down the joints.  

 

Lay the assembled skin back down on the board – 
masking tape side down. Run a damp paper towel over 
the joints to remove excess glue. Place a sheet of wax 
paper over the assembled skin. Then weight it down
