Trim and sand the edges of the sheeted foam cores. While the regular sanding block can be used, note how useful an extra
long block is for this purpose. (The one shown is made from a section of aluminum channel extrusion - with sandpaper
glued on using sanding disc adhesive. This handy specialized glue is available at hardware stores and lumber yards.
19.
Glue on the 1/4"x3/4" leading edge, holding it in place with pins and strips of masking tape. Sig Bond glue is recommended.
20.
a. Glue on the 1/4"x1/2" trailing edge in the same manner as the leading edge.
b.
Allow to dry.
21. Carve the leading and trailing edge roughly to contour.
22. Sand to exact shape with the sanding block. A pencil line drawn down the center of the leading edge from root to tip will
help get the shape true all along the wing.
23.
a. Epoxy glue the anchor block to the grooved block.
b.
Cut out the balsa sheeting above the landing gear block slots in the foam core. The slots may be located by pressing
on the sheeting or by use of the waste block from the foam core. Cut the holes in the sheeting out undersize at first
so that the opening can be trimmed down carefully for an exact fit around the landing gear blocks.
c. Excavate the foam out of the pre-cut cavity to accomodate the anchor block. The best way to cut foam is with a
brand new, sharp modeling knife whittling blade. Or you can heat an old blade in a flame and hot cut the hole.
d. Epoxy glue the landing gear blocks into the wing. Should there be any areas in the cavities which do not fit snugly
against the blocks, fill these voids with a mixture of epoxy glue and scrap foam which has been crumbled into bits.
