X-wing chest box parts. The box is vacuum formed from .125" black high
impact styrene. The are 2 strips of .25" sentra (foamed PVC) that are used
as structural support and to help adhere the back plate. The back plate
is .125 styrene.
The back plate is next glued in place. Run some cement along
the exposed edge of the sentra strips, and drop the back plate
place. Run additional cement along the top and bottom edges of
the back plate.
Place a weight on the back plate to h old it flat while glue dries.
I use a CD jewlcase and a convenient paper weight. Let sit for several
hours to achieve maximum strength. After cement has cured, score the excess
plastic with a sharp knife and snap off. Use a file and/or sandpaper to
desired effect.

Cut a hole for the hose before painting. I used a quater , drawing a circle around the outside. Test fit and adjust so that the hose is a tight fit. I use a flat tool grey for my box and middle switch. All of the detail parts shown are from the chest box detail kit.
