In this review, the master suggests making a simple spring punch with your own hands - a useful thing for a garage or a home workshop. As a basis, he uses an ordinary hairpin. Although it would be better, for example, to take a car valve.
First of all, it will be necessary to cut off a round plate from a steel round timber of suitable diameter. Also, for this homemade product you will need a segment of a stud or bolt, a sleeve from a tube, a nut, a steel washer, a spring and two pieces of a metal bar.
Now let's look at the process of manufacturing a spring punch itself. First you need to weld a segment of the tube (sleeve) to the steel washer at an angle of 90 degrees. The weld will need to be cleaned with a grinder.
The main stages of work
On a round plate, you need to make markings with a marker to find the center of the workpiece. Then you need to weld a piece of stud or bolt to it (also at right angles). For convenience, you can use the magnetic corner.
At the next stage, the master welds two pieces of steel bar to the sleeve on both sides. The edge of the stud must be sharpened under the cone on a grinding machine or with the help of a grinder, setting a flap wheel on it.
After that, you can begin to assemble the device. First, a spring is put on the stud, and then a sleeve with a washer, which is fixed with a nut.
