Apogee Black Brant VC Manual
… 45. Using a sharp hobby knife or a pair of scissors,
cut the motor band pieces out of the instructions.
Spread a small amount of wood glue on the back
(the side opposite the dotted lines) of the wider
piece and align one end with a fin line, placing the
wrap just forward of the line marked previously at
3/4" (19mm) from the back end of the body tube.
Wrap the strip around the tube twice and it will end
at the same fin line.
… 46. Apply a thin layer of wood glue to the thinner
strip of the motor band piece. Centering it between
the dashed lines printed on the first strip, begin
wrapping at a fin line and wrap the strip around
the tube. Allow the glue to dry.
… 47. Saturate the motor band with thin CyA adhe-
sive to harden it and minimize fibers being ex-
posed as the rocket is sanded for finishing. Allow
the adhesive to harden before continuing to install
the fins.
… 48. Using a sharp hobby knife, cut out the two
cardstock fin alignment guides.
… 49. Slide the main fin alignment guide onto the
motor mount tube to approximately the middle
and align the fin slots with the fin lines marked on
the tube. Test fit each fin and sand or file areas to
ensure a tight fit around the motor band as well as
against the body tube and step. Apply wood glue
to the base of the fin and slide it into place, taking
care to align it straight along the length of the tube.
Repeat for each of the fins. Allow to dry before
continuing.
