Stabilizers

First, as always with the wings ans stabs, true up your edges. Make sure your roots are squared, and the roots and tips match each other.

Draw reference lines for the cuts and angles on the top of the stabs, specifically the hinge lines and the angles at the root.

Using a band saw, scroll saw or a really steady hand, cut the angle at the root where it meets the fuse, and the angle of the elevator root. DO NOT cut the hinge line yet, you need the whole thing intact to set your incidence.

Make a root rib template and make your root ribs. make them slightly oversize so you can sand to final shape after glueing.

Now is usually when I glue in the stab socket tube...
