|---|---|
| Chisels | Intricate, controlled carving |
| Router | Efficient, versatile cuts |
| Forstner Bits | Flat-bottomed holes and channels |
Marking the Channel
Accurately marking the channel is crucial for precise cutting. Here are some detailed steps to help you achieve precise markings:
1. Determine the Channel Dimensions and Location:
Measure the desired width and depth of the channel. Decide on its exact location on the workpiece.
2. Create a Reference Line:
Draw a straight line along the workpiece’s intended center point, parallel to the direction of the channel. This line will serve as a guide for marking and cutting.
3. Mark the Channel Edges:
From the reference line, measure half the channel width to both sides and mark the outer edges of the channel. These marks will indicate where the blade should travel when cutting.
4. Mark the Channel Depth:
Determine the desired channel depth and measure it from the workpiece’s surface. Mark the depth point on the reference line, and from this point, draw horizontal lines parallel to the channel edges, extending them to the outer edges.
5. Check the Markings:
Carefully review the markings to ensure accuracy. Use a ruler or tape measure to confirm the channel’s dimensions and that it is centered on the reference line.
Marking Tools:
Various tools can assist in marking the channel, including:
| Tool | Description |
|---|---|
| Carpenter’s Pencil | Traditional tool for precise line marking |
