Balsa Taube 40 Assembly Manual - page 14
18.) Cut the 3/8 x 3/4 hardwood landing gear block to length and
glue in place. Note that it will be 1/8” higher than the fuse sides.
19.) Block sand the fuse bottom to give the bottom sheeting a nice
flat surface to glue
20.) Use the 1/8 x 3 x 30 balsa to sheet the bottom of the fuse
from the LG block aft. Use the 1/8 x 3 x 10 to sheet from the LG
block forward. Sheet this forward portion of the fuse running the
sheeting cross grain across the fuselage.
21.) Block sand the bottom at the LG block and all the forward
glue joints.
22.) Remove the fuse from the board and trim off the excess
bottom sheeting. Block sand the trimmed portions so they are
flush and clean with the sides. Cut the 1/4” square opening at the
rear of the fuselage for the tailpost.
23.) Fit the two 1/4 x 3/4 birch plywood wing mounts in place.
The shorter one goes to the front. If they are too tight, sand the
ends until you have a snug fit. The aft mount goes 1” in front of
former F-4. When positioned, glue them in place.
24.) Glue the top half of former F-4 in place. Be sure it is
centered and vertical and not slanted forward.
25.) Measure from former F-4 to the center of the two birch ply
wing mounts. These dimensions should be about 1-1/2” to the
center of the rear mount and 9-1/4” to the center of the front
mount. Mark the centers and also put a vertical centerline on
former F-4.
26.) Block sand the wing saddle to even this area out so the wing
will sit nice and flush on this surface. Be careful not to remove
much material. You just want to smooth the saddle.
27.) Glue the two 1” long landing gear support blocks in place.
Note that the groove goes against the plywood fuse doubler.
Check the photo and be sure that one has the groove towards the
rear and the other with the groove toward the front of the model.
28.) Set the wing in place. Line up the center of the trailing edge
with the centerline mark you made on former F-4 and pin the wing
down at the TE. Now measure from former F-4 and mark the
wing with the two dimensions you calculated from Step 25. These
will be for the wing bolt locations.
