How to make a clamp on your own

Locksmiths, carpentry work require reliable fastening of the processed material. This is accomplished by various devices, the most common and reliable of which is a clamp.

There are several designs of clamps. The most common is a G-shaped screw. It has a bracket covering parts and a clamping screw that moves the handle between the ends of the bracket. With its lower part, it presses the parts to the surface of the bracket.

Keyless clamps are available. They are F-shaped, with a movable middle shelf - a working unit that carries a clamping screw.

In this design, it is not necessary to unscrew / screw the screw tightly. The fixed shelf is brought into contact with the parts, the top one is moved towards them, it is locked and the elements are clamped with a small movement of the screw.

In addition to the above, tube, angle, tape, and tick clamps are known. Further on how to make a screw clamp yourself.

The easiest option is to use a hacksaw for metal. A hacksaw blade is removed from it, the body frame is shortened. A support pad is welded at one end of the arc, and a nut at the other. A long screw is inserted into the latter, on which a handle is placed on the outer edge, and a support jaw on the inside.

A screw clamp for fixing parts and sheets of wood, chipboard, MDF, chipboard, OSB, plywood can be performed as follows. They are made of dense wood with a C-shaped body with strongly elongated horizontal jaws. Make it from two identical parts. A cut is made at the docking point, leaving contact between the elements only on the outside.

In the jaws of the body arrange vertical holes on one axis. In the bottom - with a diameter equal to the diameter of the screw; in the upper - twice the large diameter. The distance from the hole to the junction of the housing elements is about a third of the length of the jaws.

From below, a screw is inserted into the hole of the lower jaw until its head rests in the bottom of the element. Its upper end should pass through the hole in the upper sponge and go 15 ... 20 mm out. A thick washer is placed on this end and an elongated nut is screwed. The last one is put on a handle with a hole for its external dimensions.

Wooden parts that need to be firmly pressed against each other are inserted between the ends of the jaws of the device. The handle rotates the nut, which leads to its turning on the screw and the pressure of the washer on the upper surface of the upper jaw. The latter bends and presses the parts against the end of the lower jaw with its end.
