Choosing the Right Tool: Thickness Planer vs. Jointer for Your Woodworking Needs

Deciding between a thickness planer and a jointer requires an understanding of your specific woodworking needs and budget. Both tools serve crucial roles in lumber preparation, but their functions differ. In this guide, we’ll explore the benefits and limitations of each tool to help you make an informed decision.

Understanding the Functions of a Thickness Planer and a Jointer

When you’re faced with choosing between a thickness planer or a jointer, it’s important to first understand their primary functions. A thickness planer and a jointer both play vital roles in wood preparation, but they serve different purposes.

Thickness Planer

Function: A thickness planer reduces the thickness of wood and provides a uniform surface on both sides.

Best For: Smoothing out rough lumber that has already been jointed or for planning down raw stock to a specific thickness.

Pros:

Essential for achieving uniform thickness across your boards. Allows you to work effectively with rough lumber.

Cons:

Does not flatten edges or faces, so further jointing may be needed.

Jointer

Function: A jointer flattens one face and straightens one edge of a board.

Best For: Preparing rough lumber by creating a flat reference surface and square edges.

Pros:

Essential for preparing lumber for glue-ups and ensuring edges are straight. Provides a flat surface for further processing.

Cons:

Cannot change the thickness of the wood.

Recommendation

If you can only buy one: A jointer is often more critical for preparing rough lumber. You can use it to create flat surfaces and square edges, which is essential for making joints in woodworking projects.

Wait for both: If you frequently work with rough lumber or need precision in thickness, it might be worth waiting to afford both. Together, they give you complete control over your lumber preparation.

Conclusion

If you primarily work with pre-dimensioned lumber or can source already planed stock, a jointer is likely the better initial investment. If you often work with rough lumber and need to ensure consistent thickness, consider prioritizing the thickness planer. Ultimately, assess your current projects and future needs to make the best choice.

Additional Tips for Woodworking Tool Selection

When choosing between a thickness planer and a jointer, prioritize the thickness planer for its versatility in surfacing and dimensioning rough lumber. You can achieve flat surfaces with creative workarounds until you can afford both. For more advice on woodworking tools, explore my Quora Profile.
