When assembling furniture and various wood products, sometimes you have to tighten the parts with bolts. In this case, for their preparation, you need to cut out a hexagonal sweat. This is usually done with a chisel in 10-15 minutes, but having made this tool, the pot can be cooked in a minute.
What you need:
- an elongated nut that matches the size of the bolt head for installation;
- grinder with cutting disc;
- triangular file.
Tool making process
In an elongated nut, you need to make a cut at the end with a depth of 5-10 mm, leaving any 2 faces opposite.
The resulting gap is trimmed with a file.
From the inside, a descent is brought out on the edges and a tip is formed.
A blind hole is drilled on a wooden surface on which you need to make a sweep with a drill corresponding to the diameter of the threaded part of the bolt.
Then a ground nut with a baited bolt is inserted into it for centering. Further, by blows on its head, the teeth are driven into the tree by 2-3 mm. The tool is turned and driven in again.
After assigning the contour, the bolt is unscrewed. Next, you only need to drive in the nut.
As the delamination progresses, the wood is picked out with a screwdriver.
After 1-2 minutes, sweep under the head of the bolt or nut is ready.
