Tools You Will Need

To get started, gather the following tools:

• Punch and chisel
• Drill

Step-by-Step Process

1. Measure and Mark

Begin by precisely measuring where the square hole will be placed. Use a pencil and a ruler to mark the dimensions (width and depth) that accommodate the size of your carriage bolt.

2. Drill Round Holes

Using your drill, create two overlapping round holes at each corner of your marked area. Ensure that the holes are adequately spaced according to the size of the carriage bolt. This step serves as an initial guide for your square hole.

3. Square the Corners

Once the round holes are drilled, take your chisel and carefully remove the material between the holes, forming a square. This technique requires precision, so take your time to ensure clean edges. A nice trick is to use a punch to start your corners for an even cleaner creation.

4. Sand and Smooth the Edges

After forming the square hole, sand down the edges to ensure there are no sharp or uneven surfaces that could impede the bolt's insertion. A smooth finish also provides a professional touch to your work.
