An Improvised Multi-Scale Tracer: A Technical Study

Abstract

This study is an attempt to device and improvise a multi-scale tracer, and to determine its feasibility and effectiveness. This gadget is ideally suited for the accurate transferring, reducing and enlarging of drawings, lot plans, patterns templates, pictures, trade signs and drawings without scales. It also has its particular advantages in terms of quickness because of its extraordinary simple design and easy handling. It is operated by just pushing forward, downward and sidewards using the transmission ratios, pole at end and pole in middle in order to come out the desired size of the design. This gadget is made out of locally discarded materials mostly aluminum and small parts of staedtler barrel and iron materials which can be found anywhere in the locality or in any automotive shops. Based on the testing and demonstrating of the completed gadget, the researcher found out that the students acquired more knowledge and skills in drawing/drafting techniques with the use of the improvised multi-scale tracer as a working model for an efficient and functional teaching and learning process on the basic skills in drawing/drafting laboratory. The use of the improvised multi-scale tracer remedies the difficulties of the students especially in making their project in drawing/drafting and enables them to submit their projects on time.
