Types of Plywood Suitable for Planing

Plywood comes in various types and grades, and each type has different characteristics that affect its plane ability. Higher-grade plywood consists of fewer voids and consistent layers, which is typically easier to plane.

Meanwhile, lower-grade plywood might have voids, knots, or uneven layers, which makes it more challenging to plane effectively.

 

Factors to Consider when Planing Plywood

Here are some basic factors that should be remembered before performing the process of planing plywood.

 

• Adhesive: Different types of adhesives are used to bond plywood layers. Some adhesives can gum up planer blades, affecting the smoothness of the surface. If you can understand the adhesive used in the plywood, it will help you anticipate planing challenges.
• Grain Direction: Plywood comprises layers with alternating grain directions. Planing plywood against the grain might cause tear-out or chipping. If you have identified the grain direction and are following the grain direction during the planing, it will minimize the plywood tear-out causes.
• Surface Quality: Pre-existing surface conditions impact the planing. These surfaces consist of nails, splinters or bumps, which require initial treatment before planing to achieve the desired results.

 

Methods of Planing Plywood

Planing plywood involves different techniques, each with its advantages and considerations. Exploring these methods helps in choosing the most suitable approach for your woodworking project.

Many different techniques can be used to plane the plywood, but each of them has its advantages and considerations.

There are two basic techniques, and we will explain in detail each.

1. Hand Planing
2. Power Planing

 

1- Hand Planing

Hand planners are controlled planners but might be more time-consuming compared to power planners. Hand-planing plywood requires skill and precision.

Here are essential tips to plane plywood.

 

• Sharp Tools: Ensure your hand plane blades are sharp to achieve smoother cuts and avoid tear-out.
• Grain Direction: During the planing process, the direction of the plane should be towards the grain to minimize the chances of tear-out and achieve a cleaner surface.
• Light Passes: Taking light passes gradually rather than heavy cuts helps maintain control and precision, especially with thinner plywood.
• Testing and Adjusting: Periodically check the planed surface for consistency and adjust the plane as needed for uniformity.

Hand planing offers a hands-on approach, allowing for greater control over the wood’s surface, but it might be more time-consuming compared to power planing.

 

 

2- Power Planing

Power planers offer efficiency and provide a different level of finesse than hand planing. However, they are ideal for larger projects and quicker material removal.

Power planers, including thickness planers or handheld electric planers, provide efficiency and speed.

 

• Efficiency: Power planers are faster and more suitable for larger projects, ensuring consistent thickness and smooth surfaces.
• Adjustable Depth: These tools often offer adjustable cutting depths for precision and control.
• Safety Precautions: Proper handling and adherence to safety guidelines are crucial when using power planers.

 

Alternatives Techniques to Plane Plywood

There is no doubt that planing is a common method for smoothing plywood, but several alternative methods also exist. We will explain three alternative methods of planing.

 

1. Using Sanding
2. Using Router
3. Using Table Saw

 

1- Can you Plane Plywood Using Sanding Technique

 

• Versatility: It is a very safe, easy, versatile method to plane the plywood, even if it can be used in intricate areas. There is no harm in this method.
• Time and Effort: Sanding might be time-consuming, especially for larger projects, and can require significant effort. So, always use this method for only a small amount of material removal. For example, if you want to reduce the 1/2″ thickness and smooth surface, sanding is the best option with the help of a belt sander or drum sander.
• Grit Selection: Choosing the right sandpaper grit is crucial. Coarser grits remove material faster, while finer grits provide smoother finishes. So, always choose between the 150-220 grit sandpaper.

 

2- Can you Plane Plywood Using Router

It is also the best method to smooth the plywood edges. Routers have shaping bits, which create precise cuts and shaping. But it requires only a setup to fix the piece of plywood firmly.

The smooth surface quality depends on the securely fixed workpiece.

Once you finish all the depth and edge settings, you can start planing the edges according to your needs.

 

3- Can you Plane Plywood Using Table Saw

Table saws also work the same as routers, but they consist of cutting blades rather than shaping bits.

It also requires object setting according to specifications. Always remember that a table saw requires expertise in handling for optimal results.

The initial setup time can be high, but after setting it up, it is easy to operate. You can use this method for heavy projects.

 

Comparative Analysis – Planing vs Sanding for Plywood

After reading all the planing techniques, choose the appropriate technique according to your needs.

But first, understand the pros and cons of all techniques for better selection. Because each method also has pros and cons.
