For airplane modelers, maybe one of the most difficult things to do when scribing panel lines or adding rivet detail onto difficult, complex surfaces is to use a tool, some sort of guide that can be used to drive the scribing or the riveter tool with confidence.
Usually, the literature suggests to use Dymo tape, a self adhesive tape, that has a rather hard plastic strip, but doesn't solve two problems.
1. In corners or on small radius surfaces, it is hard to use, 2. When riveting, it gives no help for measuring the distances between the actual rivet lines.
For helping about these above shortcomings, we made this flexible-ruler. This is a 0,2 millimeter thick copper strip with photo-etched millimeter or inch scale. The flexible ruler is available in 15 centimeters or 6 inches long versions. Because of the properties of copper sheet, the ruler doesn't want to straighten out such as stainless-steel rulers, and if one uses it on a certain surface, it can even be used to copy the actual pattern on another location - for scribing, measuring, or riveting to mention a few possible uses.
NOTE: The flexible ruler may crack in, or even break when bent back into small angles especiall at the at the scale part of the ruler. But when used with care, we think it can be a handy tool in your modeling inventory for years!
