For the wedge I used a piece of steel, 1,5 cm thick. Then I cut a piece 20 cm in length

The biggest part of the wedge is 24mm and the smallest is 7mm. Mark the wedge with a pencil and cut it.

For the feathers I used construction steel bars 19 cm in length. Cut 2 of these.

The diameter of the two feathers should be 22mm. To achieve this, it's better to cut the steel bars with an angle.

The Final Piece
