Id like to thank you all for the help. I think I am now ready to begin the replacement of the leading edge of the elevator, and will need to do the same for the T/E of the stab. I picked up a piece of balsa that was the exact height, however will need to cut and sand to the correct width, plus sand the angle on the edges. I wasnt able to find a piece having the same width and height that would just need to have the angles sanded in.

Before I begin, does anyone have any tips on how to insure perfectly straight cuts, and nice sanding of the angles? I will be using basic hand tools and sanding paper/blocks. Id like to get this right the first time (after ive glued that is).

Thanks again for the help so far.
