8.
Join R6 dihedral break rib assembly with 1/32 in. ply face facing outside of assembly. Fit R6 to angle of spar
web then stand wing tip assembly on end and flatten R6 to work surface prior to bonding with thin CA glue.
9.
Locate the 1/16 in. ply tip spar pocket S10 (sheet 20/21) and fit to FORWARD surface of spar web between rib
R6 and R7 as illustrated below. The outer edges of S10 must fit flush against ribs and spar caps. Once
satisfied with the fit bond with thin or medium CA glue. Note: don’t make a mess of the glue job here as globs
of glue along the inside edge of S9 will cause fit issues when installing the Delrin tip spars.
10. Enclose the tip spar pocket by laminating the 1/16 in balsa webbing S11 (sheet 04/21) spanning rib R6 and rib
R7 as illustrated below. Note: it may be helpful to lightly sand the edges of this part (just enough to remove the
laser burn) then bond with medium CA glue. Attempt to apply glue sparingly to the forward surface of the S10
plywood pocket to minimize any glue that may squeeze out inside the tip spar pocket and cause fit issues with
the tip spar.
