The trailing edges of the elevator uses foam blocks that are cut to shape and glued in place. To create these foam blocks I had to cut out paper templates and use spray adhesive to hold them onto the rectangular foam chunks. Once the adhesive had dried overnight I could use the bandsaw to roughly cut the foam pieces, and then the bench-top sander to trim the pieces closely to the lines on my paper templates. This all worked out quite well. Unfortunately, one piece of foam tipped over and out of my hand during sanding and is very slightly misshapen on one side, but I don't think it is significant enough to be a concern since the glue that will be later used (tank sealant) is quite viscous and can fill that slight void easily.

Next was to take two of the elevator skins and trim off an excess corner that was the result of the manufacturing process. I marked the line using a ruler and then cut the bulk of it using sheet metal snips, and then refined the line using the bench-top grinder again.
