Clamping the Wing

Clamping the trailing edge as the glue dries greatly increases the strength of the bond between your two wing surfaces. With as many clamps as you have, ensure that the trailing edge is firmly held together across the full span. A second shorter ruler, placed ahead of the main one in the centre of the wing, may help to ensure a good bond around the silencer cut-out area.

No Clamps?

Simply spread your body weight along the full width of the ruler as best you can using your forearms. With elbows at the wingtips and palms in the centre of the wing you should be able to body-clamp the glue joint quite successfully. If your arms start to get tired, resting your head on your hands in the wing centre might look very ungainly but will do the job nicely.
