Step 1: What you will need:
- A blank key that has the same V grooves as the real one. For the most part if they will not duplicate it they should sell you the blank, Lowes sold me one for $1.97 (the total cost of this project)
- A filing set with different types if files (mainly a round, and a D shaped file)
- Non-hardening clay that is not reactive to heat
- A grinding wheel or dremel tool to help speed up the process
- A vice (optional)
- A lead melting pot with Lead or a soldering iron
- Some side cutter snips
Step 2: Negative Copy of the Key
- We will do this by molding the clay into a round circle with a rolling pin.
- Then we will cut it in half, try to make it as strait of a cut as possible.
- Press one side of the key into the clay and make it flush to the clay.
- Repeat on the other half of the clay with the opposite side of the key.
- Now line up the two half's of the clay, perfection is a must, and lightly apply pressure around the edges of the key imprint in the clay to where it is the same thickness of the original. Now you can press the rest of the clay farther away from the key together to form a better seal so if any molten led does seep out it will not go very far.
