Scribing and chopping
Leather punching seems simple, but it still has a certain amount of attention in actual operation.
Sometimes the misalignment of 1 hole will make the finished product that you spend days making end of life prematurely.
Required tools: Edger
After the two pieces of leather are glued together, use a liner to draw a marking line along the edge of the leather (also known as a decorative line, the oblique edge is generally 1.5mm away from the edge of the leather, and the diamond cut needs 2mm) to provide guidance for the subsequent cutting steps.
After adjusting the distance, draw the marking line, press the handle at a low angle when drawing a straight line, pull out the indentation evenly, raise the angle of the turning position, and the handle and the table may be at 90°;
Tools: Laminated rubber backing plate, tendon hammer, Chisel Pricking Iron
There are many types of cuts, the most common ones are diamond cuts and oblique cuts. In this demonstration, we use the 3.85mm without it. For oblique and flat cuts with finely ground tooth tips, it is best to stick a layer of 2mm or more thick leather on the hard backing plate to protect the cut tips when striking. The use of a low-hardness tendon hammer not only provides better control flexibility, but also protects the object being struck.
Cut along the direction of the positioning line. In order to make the double-layer glued leather corners fit better and avoid flipping, there is an extra cut hole at the front and back of the suture.
Hit the slanted cut horizontally with a tendon hammer, so that the tip of the cut just penetrates the back of the leather.
