Here are some of the not so ordinary tools we're using to build our plane. Starting from the front left there are 3 kinds of tin snips, spring-loaded punch, cleco pliers and various clecos. Then a cleco air gun(a luxury) and finally a hand rivet squeezer. Back row- hand seamer, nibbler, dimple pliers, two air drills, various deburring tools, and a rivet gun. In the back is the two part epoxy chromate.

The process of working with aircraft sheetmetal is fairly involved.  Any holes drilled in the process must be step-drilled to the proper size and then thoroughly deburred prior to use. The holes must be the right diameter and not have any rough edges or cracks.  A burr or rough edge might allow a crack or weak area to develop.  Our kit is designed not to require the use of jigs (although we have used several already to help us along)and parts are located and installed based on holes that are factory drilled in skin parts and some frame members.  Because of this, clecos are used in large numbers throughout the process.  In most cases there are several rounds of put-it-together and take-it-apart before we actually get around to permanently putting the part together.
