Griffon 2000TDX - 1/10 scale

Take the plywood disc which was removed when the duct ring was cut out and fit this inside the duct inner wall, in the end opposite the duct ring. This should not be glued, but is just to keep this end of the duct circular while the outer wall is fitted.

Glue the outer wall to the duct assembly. When the glue has dried, remove the disc and trim and sand the duct ends.
