Special tool for engraving riveting lines on models. Comes with four interchangeable engraving discs. The fine rivet lines belong to many aircraft models. However, they can be quickly removed with a small inattention during construction. With the rivet maker, you can re-engrave your own rivets. The engraving discs included in the set allow you to produce rivet lines with four different rivet spacings. This covers a large number of aircraft types and scales.
