Aileron continued
Photo 1, G10 hinges, notice the step cut that catches on the trailing stringers so hinge can't pull out of wing. Also drilled 6 glue holes so Hysol can get a good bond once in the mounting block.
Photo 2 - 3, hinges installed in ailerons with hinge pin in place and rough fit in the wing.
Photos 4 - 5, Mounting blocks for the hinges, They are cut so as to stay just under the bottom skin once applied. Slot is cut so as to have a snug fit with the hinge, all of this done on the band saw.
Photos 6 -7, Dry fit of the mounting blocks in the wing. Did a little re cutting to make sure blocks stayed inside the skin to reduce hand sanding before applying the bottom skin.
Photos 8 - 11, Show the mounting blocks glued in. Titebond used to glue mounting blocks to skin and Hysol used to glue hinge in the mounting block slot. I used plenty of each glue to insure block and hinge won't come loose. I will use Hysol around the mounting block once the Titebond has completely dried. I mounted the outer wings on the center section and then took a good look at the alignment of the ailerons to the total wing. All looked pretty close and just needed a little adjustment to be correct. Thank goodness for Hysol as it gives you time to make the required adjustments.
