Both Joiner Assemblies 

are now bolted in place, 

but  the  webs  have  not  been  glued  yet.    The  front 
joiner/web  assembly  is  still  in  position,  but  the 
rear  joiner/web  assembly  has  been  pulled  away 
from the spars so that glue can be applied. 

Joiner/Web  Assemblies 

are  glued  and  clamped 

firmly.  Temporary pieces of plywood are used on 
the  opposite  side  of  the  spars  for  clamping 
purposes.    Use  epoxy,  but  keep  it  away  from  the 
actual  wing  joint  between  the  two  lite-ply  W-2 
wing ribs. 

Plywood  Scraps

  are  glued  above  and  below  the 

C-channels for extra strength.  Rear channel too! 

Plywood  Scraps 

are  glued  above  and  below  the 

joiners for extra strength.  Rear joiners too! 

WING JOINER INSTALLATION, CONTINUED...    





Remove the outer panel and the webs.  Drill at the marks (9/64’), put the webs back in the outer panel, then 

slide the outer panel into its final position against the center panel.  Bolt the joiners to the webs with this hardware: 
 

Each Front Joiner - Three 6-32 x 1" Socket-Head Bolts, Six #6 Washers, and Three 6-32 Hex Nuts 
Each Rear Joiner - Three 6-32 x 3/4" Socket-Head Bolts, Six #6 Washers, and Three 6-32 Hex Nuts 

Notice I used a washer under the bolt heads to keep the bolts 
from digging into the aluminum. 
 



Now  the  webs  are  ready  to  be  glued  into  place.  

Without  disturbing  the  position  of  the  wing  panels,  work  the 
webs away from their spars.  Apply slow-drying epoxy to both 
the webs and the spars, reposition the webs, and clamp them in 
place.    CAUTION!    Be  careful  not  to  get  any  glue  in  the  joint 

between the wing panels.  The whole idea here is for the wing 
panels to come apart! 
 



 When dry, remove the wing from the board, loosen the 

set screws and separate the wing panels.  Mix another batch of 
epoxy and use a disposable brush to coat the area thoroughly 
between the top and bottom spars, including the internal webs, 
spars, and mounting hardware. This is not the place to be stingy 

with the epoxy! 
 



For  extra  strength,  glue  scrap  pieces  of  hard  plywood 

(3/32 or 1/8) along the top and bottom edges of all the joiners and 

C-channels.  This is a very important step because there will be a 
lot of stress and pressure on the channels trying to twist them out 
of position, especially when flying aerobatics.   
 



Having  fun?    Good!    Repeat  these  steps  for  the  other 

side....
