A scriber (scriber or Scriber) is a tool for marking metal surfaces. Such products of various designs are produced by industry and in terms of quality they differ greatly. In order not to waste money, you can make it yourself, even with low qualifications and without expensive materials.
Needed to make a scriber
For this purpose, a TVS hex head bolt with a diameter of 10 mm, a length of 150 mm and a drill made of HSS steel 3 mm with a hardness of 60-62 HRC are suitable. You will also need the following tools and materials:
- vice;
- Bulgarian;
- vertical drilling machine;
- set of files for metal;
- drill;
- core and hammer;
- Super glue.
The process of making a metal scriber
Holding the bolt in a vice, cut off the head and most of the threads.
We insert the bolt shaft into the chuck of the drilling machine, turn it on and use a grinder to round the end formed after removing the head.
We turn the bolt over and form a cone in place of the remaining thread and dull its tip.
We correct the cone with a file and make two belts on the rod to make it easier to hold the tool with your fingers in the future. We finally form the other end.
We clamp a drill (broken) made of HSS steel with a diameter of 3 mm in the drill chuck and form the working part in the form of a sharp cone. The tip can also be made of silicon carbide or tungsten.
We tap the blunt cone of the bolt and drill an axial hole with a diameter of 3+ mm and a depth of about 25 mm.
Squeeze a drop of superglue into it and insert a pointed drill with the fastening part.
The scriber is completely ready to work on both soft metal and steel.
