Scarf Joint

Posted on Updated on

The top RS-8 on the fuselage sides has a scarf joint located in the cockpit area. To make it I cut the two pieces of wood, placed them side by side and sanded them to the same profile.



The end result looks great.

    The standards for wooden aircraft construction and the EAA hints for homebuilders strongly advise against sanding the mating surfaces of a scarf joint. You may want to reconsider this area.

      I would appreciate if you could elaborate on this subject.

      Making the surface too smooth is certainly not a good idea, a rough surface provides better adhesion with the epoxy. In my situation the sanded area is rougher than the circular saw left it. The surfaces are not so perfect that all the glue was squeezed out.

      Have I overlooked some other aspect that would be a concern?
