-
Trim the lip from the perimeter of the parts
sheet so it will lay flat on the work surface.
-
Hold short strips of masking tape and attach
it to each of the “shells” to act as handles and ease construction during
assembly.
-
Attach a full sheet of 180
grit sandpaper to the work surface with tape.
-
Use the tape handles to hold
the parts while you sand the backside of the shells. This will thin the
plastic around the parts and remove the “roll” at its base.
-
Apply pressure
evenly while sanding and stop before the sandpaper breaks through. Your
progress can be monitored by holding the parts sheet up to a bright light.
-
Finnish removing the parts with an a razor Note: Allow the sand paper to
break through on the doubler shells (Identified by the groove molded down
the center).
-
Apply plastic cement to the
inside edge of the shell then install the bonding doublers.
-
One half of the doubler
should be inside the shell while the other half protrudes from the shell.
-
Once the cement has set, repeat the step to the same shell half.
-
Apply cement to one of the doublers near the shell seam and place the other
shell half in place. Position for best fit and allow the cement to set.
Apply cement to the other side and close the gap to finish bonding the
shells together.
-
Allow the bonds to dry completely; overnight would be best.
-
Use the edge of the hobby
knife to scrape away the flashing around the seam. If the plastic gums up
while scraping, the cement is not dry enough. Fill the seam voids with
plastic model filler then sand and prime.
-
Bond the fins to the fin
back plates and allow to dry. Trim the excess back plate flush with the
molded fin.
-
To attach the fins, scrape
away any primer so the cement will hold. Bond the opposite fin in place next
then while looking at the end view make adjustments to the fins so they line
up.
-
Repeat the steps to attach
the last two fins in place. You will have about a half hour to make
adjustments to the fin angles. Once you are happy with their positions,
allow the cement to dry completely
-
Prime the model and fix any
unnoticed defects. Paints with strong solvents may soften the plastic so
light coats should be applied or at least tested on scrap plastic. Tamiya
brand paint is recommended.
-
Model Master Brand liquid
cement is recommended. Other adhesives can be used but should be tested on
scrap plastic before assembly begins. CA adhesives work also, however the
use of “kicker” will harden the plastic and cause it to crack.
-
Panel lines
can be added with a sharpie pen or for fainter lines, a pencil with a soft
lead will work too.
