In the previous article about metal cutting examined the use of a Olfa Cutter to trim sheets. Franco at Flying Legend advised that the factory had supplied stainless steel strip drilling jigs. A quick search of the parts supplied identified a stainless steel strip 20 mm wide punched at a 30 mm pitch. This had been packed away with the thought that this looked very important and must therefore go somewhere important - not so.
Its application is the same as the cutting guide outlined in the original article but its can also be used as a drilling jig for the fixing of components. Begin steel it provides a convenient edge guide when dressing the cutting burr with the file.
The other items shown with the punched strips is the flat strip to manufacture the attachments of the fiberglass tips to the aircraft. The folded 30 x 30 angle is just that, folded angle to allow the manufacture of various brackets as required by each individual aircraft.
