9. Pull the string back to one end of the stab. Slide the
masking tape along the string until the line is even with the
trailing edge of the stab.
❏
10. Swing the string over to same spot on the other side
of the stab. Adjust the stab and the tape on the string until
the stab is “equalized” and rotationally centered.
❏
11. Remove the stab. Glue the stab into position with
30-minute epoxy using the pin and string to check alignment
as done in the previous steps. A couple extra T-pins may be
inserted through the stab and into the balsa saddle to tightly
hold everything in position until the epoxy hardens.
❏
12. After the epoxy from the previous step has hardened
and the T-pins removed, any visible pinholes may be
reduced by going over them with your sealing iron.
