Introduction: Wedge and Feathers for Rock Splitting (or Plug and Feather)

The image of wedge and feathers is taken from the internet. The dimensions of the original tool are different.The tool is for a hole with diameter 22mm.

Step 1: Wedge

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

Step 2: Dimensions of the Wedge

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

Step 3: Cutting the Wedge

Cut the wedge with an angle grinder

Step 4: Final Piece of Wedge

Step 5: Feathers

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

Step 6: Dimensions of the Feathers

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

Step 7: The Final Piece

The final piece should be like this. Cut other 2 or 3 to break the rock easily.
