Just a vice in the workshop may not be enough. It is convenient to fix large workpieces with a clamp. You can make it from unnecessary valves and strip scraps.
Materials:
- automobile valves – 2 pcs.;
- strip 30x2 mm;
- M20 pin;
- nut M20;
- square 10x10 mm.
Clamp manufacturing process
To make a movable jaw for clamping a clamp, you need to cut off the valve stem, leaving approximately 10 mm. Its remainder on the plate is ground into a ball.
Next, the end of the M20 pin is drilled so that the ball at the end of the valve fits freely into the resulting hole.
Anti-slip notches are cut on its plate.
It is necessary to weld a sliding lower jaw holder from strip sections. It will slide on a frame made of the same strip.
A second valve with a shortened rod and notches on the plate is welded to it.
The upper holder is made of a square, to the end of which an M20 nut is welded. It is welded to the base of the strip clamp. A pin is screwed into the nut. A sliding bracket with a second jaw is placed on the base.
The hairpin is shortened and equipped with a collar. Next, you need to movably secure the valve with the ball in it.To do this, it is drilled from the side, and a ball from the bearing is welded into the hole. Thanks to this, the pressure angle of the sponge will be adjusted.
The resulting clamp has a large grip; it can be clamped and removed fairly quickly.
It can be used both when working in carpentry and metalworking workshops.
