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.
