❏
11. Cut the front of the fuse until the 1/2" x 1/2" x
1/2" hardwood nose block will fit. Glue the nose
block to the fuse, then carve and sand it to the
shape shown on the plan. Note that the grain
direction of the nose block runs parallel with the
length of the fuse.
❏
12. Use your bar sander and progressively
finer grades of sandpaper to round the edges of
the fuse as shown in the cross section drawings
on the plan.
❏
1. Use a balsa block or something similar to
support a ballpoint pen so the tip will be 1-1/8"
above your building table. Mark the bottom of the
hatch on both sides of the fuse extending from
the lines you marked earlier 11" forward. As you
proceed, press down on the fuselage over the area
where the bottom is flat as shown in the photo.
❏
2. Use a razor saw to cut the aft end of the hatch
along the lines you previously marked. Cut the
front of the hatch at an angle 11" from the aft end
of the hatch.
❏
3. Use a fresh #11 blade to cut the bottom of
the hatch along the lines you marked on both
sides of the fuselage. Note how the knife in the
photo is inserted at an angle, allowing the tip of
the blade to trail behind. This provides more
stability, allowing you to steer the blade, not the
wood grain. Also note that the cut should be
parallel with the bottom of the fuse.
❏
4. Use a fine razor saw to cut former 2 as
shown in the cross section on the plan so you can
remove the hatch.
Neato!
Cut parallel with the fuse bottom.
