In many chest furniture, the door is also attached with two pin hinges, inserted with pins into drilled holes. That is why it is very important, that the spacing of the holes in both the furniture and the door is identical. We can achieve this by drilling them with a tool made of a metal square. Two pilot holes should be drilled in the angle. You should also make a lateral resistance, e.g.. by bending the leg of the angle bar. We push the door up to this resistance while drilling.
