Paul Straney working his magic.
This glider project began with the fuselage from a motorized airplane. There are a few mods needed to make it fit for the glider version. One modification requires removing the circular pipe (it looked like a veritable Hula Hoop) that was welded to the very front of the fuse and held the front edge of the fabric such that it blended into the engine. Since there is not engine on the glider, there is no need for the Hula Hoop. Paul cut it off, and then filed the excess metal down to make a nice smooth surface where it had been welded. The lesson here is make sure you leave a little bit when cutting away the excess. That way you can file it down slowly and it will look like it never had an appendage, and it will be strong because there are no nicks in the remaining metal. Having seen Paul's handiwork, I can say that once a coat of paint is put on the fuse, you will never know it had a Hula Hoop.
