Greetings to all lovers of crafting something from nothing.
Our homemade It will be of interest, first of all, to masters engaged in the manufacture of knives. We make the vise of a knife maker.
Tools needed.

3. Drill
4. Electric drill
5. Vise.
Materials and consumables needed.

2. Metal profile 5 x 2.5 cm
3. Steering finger
3. Two steel couplings Ø 20 mm
4. Two steel couplings Ø 15 mm
5. Two shafts Ø 20 mm
6. Two shafts Ø 15 mm
7. Pipe Ø 20 mm
8. Pipe Ø 15 mm
9. Metal square 10 x 10 mm
10. M8 nuts
11. M8 Lamb Bolts
12. Sandpaper
13. Broken ratchet wrench.
Rough draft of a future vice.
The most important part of the design is the ball. We cut it off from wallowing in the garage steering finger of an unknown truck. Old ball joints are also suitable. The ball was smoothed out with sandpaper.
From profile 5 x 2.5 mm. cut off 15 cm and weld to the ball.
We clean the welding seam with a flap wheel and sandpaper.
We drill holes, weld nuts and screw the wing bolts from them.
From the profile 3 x 1.5 mm. you need to make two U-shaped blanks. The dimensions of these blanks must be calculated based on the size of the available ball and the thickness of the countertop on which it is planned to install a vice.
The first workpiece we obtained with an external size of 13 x 8 cm. We cut two sections of 8 cm from the profile. One cut of 90 degrees. second 45 degrees. on the wide side of the profile and one segment of 13 cm. in which both sections are 45 degrees. downward.
We weld the parts together and clean the seams.
Since we specified the dimensions during the manufacturing process, some parts were cut off with a margin and then adjusted to the desired size.
From bends Ø 20 mm. cut the long thread.
Using a drill, we chamfer on the inside of the cut, for a better fit to the ball.
Couplings Ø 20 mm. welded to the workpiece, we clean the seams and screw the threads into them.
The first workpiece is ready. The second workpiece turned out to be 16 x 6 cm in size. We make it similar to the first, only cuts of 45 degrees. do on the narrow side of the profile.
To fix the future vice on the countertop, we weld a sleeve Ø 15 mm to one of the ends of the workpiece.We screw in a long thread with a welded handle from a square 10 x 10 mm.
Now you need to put the vice together. To do this, we make the simplest rotary assembly.
From pipe Ø 20 mm. cut 4 cm. drill a hole, weld a nut and screw the wing nut. From pipe Ø 15 mm. cut 4.5 cm, strip and insert into the workpiece from a pipe Ø 20 mm.
Trim pipe Ø 20 mm. welded to the lower workpiece and Ø 15 mm. to the top.
The vise is almost ready. Clamp the ball between the threads, calculate the desired position of the handle and weld. At first they wanted to make a pen out of a square, but in the process, they discovered a broken ratchet in the workshop and welded it.
Well, painting the product will certainly not hurt.
Here is such a design, we install it on a table and set it in a position convenient for work.
In order not to damage the blade, we clamp it through the gaskets. We cut out of the PCB and pasted the rubber on top, pasted one gasket inside the profile. You can use wooden planks or plywood.
You can start making a knife masterpiece.
The vice holds the knife firmly enough, but if significant loads are expected during operation, then we put an additional stop made of the coupling and a long thread Ø 15 mm.
All good and good luck in work.
