Not so rare situation when you urgently have to drill a hole in the tree and drill is not at hand. It is not necessary to ring round friends in the search for the appropriate tool — in just half an hour you can make a brace that will serve you for many years. To do this, pick up a steel rod with a diameter slightly smaller of the alleged holes. One of its ends it is necessary to flatten (you can do this by pre-heating the rod to red heat) and grind as shown in the figure. The tool is no longer dull, temper his heat again and let cool in oil or salted water. That’s all. It remains to bend the rod in the form of the knee and at the upper end of freely put on the handle of a file.
