For this homemade the author took 15 nails
And a piece of the old board from which he will make the basis for the puzzle.
And he will also need a stencil from an ordinary piece of paper with such markings. Attaching a stencil to the board, the author made a mark of the desired size of the workpiece.
Then sawed off the board at the mark.
Then I marked it in this way.
And with the help of a planer he took off all the excess. Leaving the thickness of the future base 3 cm.
Then, on a stencil, I cut it off on the sides.
Then he processed the workpiece with sandpaper.
Next, the milling cutter for the milled edges.
The next step, the author put a stencil and outlined places for holes.
The author selected a drill bit as large as the size of nails.
And he began to drill holes. All holes should be made of the same depth.
After he made the holes, the author went through the base once again with sandpaper.
Then set the nails into the holes.
Well, the author got such a puzzle. The principle of this puzzle is to place the remaining 14 on one nail.
Author's answer: this is done in this way.
This is the principle of this puzzle. Thank you all and all the best.
