Thickness Planers

Thickness planers are indispensable tools in a woodworker's shop, primarily used for smoothing rough lumber and achieving uniform thickness across a piece of wood. This guide will explore the functionality of thickness planers, the different types available, and best practices for achieving the best results.

Types and Variations

• Portable Thickness Planers:

  • Usage: Ideal for small workshops and DIY enthusiasts who need to plane various types of wood while conserving space.

  • How to Use: Set up the planer on a stable surface, adjust the cutting depth, and feed the wood through the planer evenly.

  • Example

• Stationary Thickness Planers:

  • Usage: Larger and more powerful, designed for heavy-duty planing tasks and frequent use in a professional workshop.

  • How to Use: Ensure the planer is securely installed on a stable platform. Adjust for the desired thickness, and use rollers or additional support for larger pieces of wood.

  • Example

• Benchtop Thickness Planers:

  • Usage: Compact enough to fit on a bench but powerful enough to handle a wide range of woodworking projects.

  • How to Use: Place on a workbench at a comfortable height, set the desired thickness, and feed the wood through, taking care not to overload the machine.

  • Example

How to Use Thickness Planers

• Technique:

  • Always feed the wood grain side up to minimize tear-out. Keep the wood flat against the planer table to ensure even thickness.

• Safety Measures:

  • Wear safety glasses and hearing protection. Keep your hands clear of the feed and exit areas when the machine is running.

• Preparation Tips:

  • Check the wood for any metal objects like nails or staples before planing, as these can damage the blades.

Tips for Precision:

• Take multiple light passes to reach the desired thickness, rather than trying to remove too much material in one pass.

• Use infeed and outfeed tables or supports to handle long boards and prevent snipe.

• Regularly check and adjust the blades to maintain a sharp edge for clean, smooth cuts.

Maintenance and Care

• Blade Care:

  • Regularly inspect and sharpen or replace the blades to keep them in optimal condition.

• Cleaning:

  • Clean out wood chips and dust after each use to prevent buildup that could affect the machine's performance.

• Lubrication:

  • Lubricate moving parts according to the manufacturer's instructions to ensure smooth operation.

Common Projects and Applications

• Dimensioning Rough Lumber:

  • Quickly bring rough lumber to a consistent thickness and prepare it for final finishing or assembly.

• Smoothing:

  • Smooth out warped or twisted boards that can be difficult to handle with other tools.

• Custom Projects:

  • Achieve custom thickness for specialty projects or when matching old with new wood in renovation projects.

Safety Tips

• Never reach over or near the blades, especially when the planer is operating.

• Use push blocks or push sticks to feed the material safely through the planer.

Purchasing Recommendations

• Power and Capacity:

  • Consider the maximum width and depth of the cuts you plan to make frequently, and choose a planer that can accommodate these dimensions.

• Features:

  • Look for planers with features like depth stops, dust collection ports, and reversible blades for added convenience and longevity.

Thickness planers are critical for any serious woodworker looking to produce high-quality, professional pieces. With the right knowledge and practices, you can use a thickness planer to enhance the quality and consistency of your woodworking projects.
