Reinforcing the Edges

October 18, 2016

The thickness of the tip is less than 1/16″.  You have to build up the edges to 1/8″ if you want to use the screws, like I do.  This means that I have to apply several layers of fiberglass to the inside of the tips in order to build it up.  I’m still getting the hang of this.  In addition to the build up you have to put reinforcement strips onto the edge for the nutplates to attach to.  I made my strips (W-728) from a recycled rudder skin.  The thickness of the metal just needs to be .02, which is what the rudder is made from.

    Saw you using the dremmel to cut those thin strips. You should do a google search for an Olfa knife. Two or three strokes to score the .020 and those strips would have popped right off. Wonderful tool, and only cost a few bucks!
