For self-production of gaskets made of cardboard, paronite, rubber and other materials, a punch is sometimes required to make even neat holes. Such a tool is not difficult to make with your own hands. Its production will take no more than an hour.
- reinforcement of a larger section than the hole punch needed;
- a drill equal to the diameter of the hole that you want to cut;
- machine development.
Hole punch manufacturing process
It is necessary to cut off a piece of reinforcement with a length of 10-15 cm.
At the end, it is drilled to a depth of 3-4 cm. It is necessary to use a drill equal to the required diameter of the holes in the gasket.
After drilling, it is necessary to grind the edge of the reinforcement from the outside to make a sharp edge around the circumference. It’s important not to overdo it. If the plane of the point is violated, it must be leveled by grinding off the protruding part to the depression.
Cut a window slightly higher on the side of the reinforcement within the drilled cavity. It is needed to clean the hole punch.
If the tool is needed once, then it can already be used. Just grease the part for which the gasket is needed and attach it to cardboard or paronite.
Then it is cut out on a soft lining according to the left impression.
To increase the life of the tool, its working edge can be heated red-hot with a burner and lowered into working off.
Thanks to the hardening, the hole punch will keep sharpening longer, and the point will stop wrinkling.
