Next, we are going to drill two holes in wood for our button. You could also use a laser engraver or carve a design for this step, but drilling will work well for this example.
For this step, you will need a piece of wood, a power drill, a 1/2" forstner bit, and a 1/16" standard spiral drill bit. Secure the forstner bit into the chuck of your drill, and drill a 1/8" deep hole into your piece of wood. Be careful not to go past 1/8" deep while drilling because you will have to use more metal powder to fill the hole.
Once you have finished drilling with the forstner bit, remove it from the drill, and secure the 1/16" drill bit into the drill chuck. The forstner bit should have left a small impression in the center of the hole. Place your 1/16" drill bit in that impression and drill a hole through the piece of wood. This hole will be used for a wire that will be placed in the metal powder.
Now that you have both holes drilled, we are ready to add the wire and metal powder.
