Great Planes Spirit 100 Sailplane Kit - GPMA0550 - Manual (Page 38)

D 11 Sand the fuse sides and bottom flush with the front of
former F1 and glue the 1-7/8" Balsa Nose Block (SPT1F10) in
place with med or thick CA The bottom of the nose block should
overlap the fuse bottom by about 1/32" to allow for sanding to
final shape.
D 14 Install the two 1/4" x 1-1/4" x 1-15/16" Birch Ply
Wing Bolt Blocks by inserting them at an angle behind BB2 while
pushing the pushrod tubes down out of the way Once the blocks
have cleared the tripler, slide them into place behind former F5
and in front of former F6 Securely glue these in place with epoxy
Glue triangle stock around each one for extra strength
D 12 Drill four 11/64" (5/32" is tight but will work) holes in
the 1/8 ply bottom for the towhook There should be four inden-
tations to show you where to drill Gently Tap the four 6-32
Blind Nuts (NUTS001) into the holes (from the inside of the fuse)
using a dowel and a hammer and securely glue them in place with
med or thick CA or epoxy around the outside edges of each blind
nut (be careful not to get glue inside the blind nut)
D 13 Locate the Ballast Box Top BB3 (SPT1F17) and the
1/4" x 1/2" x 1" Basswood Ballast Box Handle (SPT1F16).
Roundoff the corners and edges on all but one 1/4 x 1 side Glue
it to the center of the ballast box top with the rounded corners up
Test fit the ballast box top in place.
D 15 Assemble the two wing halves and temporarily lay the
wing in position on the fuse Sand the wing saddle if needed, to
achieve a nice fit between the wing and the fuse Center the wing
on the fuse and use a string as shown in the sketch to make sure
it is on straight Make a couple of alignment marks on the wing
and fuse and apply masking tape to help you make sure it stays in
position while drilling the wing bolt holes
IF YOU ARE BUILDING A
RUBBER BAND ON WING SKIP
AHEAD TO STEP 20! D 16 Firmly hold the wing in place on the fuse and drill a
13/64" hole down through the hole in each front wing bolt plate
