Hand planes are among the most fundamental tools in traditional woodworking. They shape surfaces, smooth edges, and create precise joinery with a level of control that power tools often cannot match. However, the array of plane types, sizes, and brands can be daunting for even experienced woodworkers. This guide will explain the different types of hand planes, their specific uses, and the essential setup tips to get them performing at their best.

Let us begin with the most common plane: the bench plane. Bench planes are general-purpose tools used for flattening and smoothing wood. They come in several numbered sizes. The No. 4 smoothing plane is the most versatile and the one we recommend for beginners. It has a blade about 2 inches wide and a length of around 9 inches. It is used for final smoothing after a larger plane has flattened the surface. The No. 5 jack plane is longer and used for initial flattening and for removing stock quickly. The No. 7 jointer plane is very long and is used for truing long edges and flattening wide panels. For most woodworkers, a No. 4 and a No. 5 will cover 90 percent of their needs.

Block planes are smaller than bench planes and are designed to be used with one hand. They are ideal for trimming end grain, chamfering edges, and fitting joints. The low angle of the blade makes them particularly effective on end grain. A block plane is a must-have for any workshop. They are compact and easy to adjust.

Specialty planes are designed for specific tasks. The shoulder plane is a narrow plane used for cleaning up tenon shoulders and rebates. Its blade extends to the full width of the sole, allowing you to cut into corners. The router plane is used for fine-tuning the depth of grooves and dadoes. It is also useful for cleaning up the bottoms of mortises. The rebate plane, also known as a rabbet plane, is designed to cut rebates along the edge of a board. It has a fence that guides the plane along the edge and a depth stop to control the cut.

When choosing a plane, the quality of the blade material is critical. High-carbon steel blades hold a sharp edge well but are prone to rust. A2 steel is more durable and holds its edge significantly longer. It is a premium material often found on high-end planes. The blade should also be thick enough to resist chatter. Thin blades vibrate and produce a rough surface.

The setup of a hand plane is just as important as the plane itself. The first step is flattening the sole. The sole must be perfectly flat for the plane to produce consistent shavings. Check the sole with a straightedge. If it is not flat, you will need to lap it on a flat surface with sandpaper. Start with 120 grit and progress to 400 grit. This process can take time, but it is essential for performance.

The blade must be sharpened to a razor edge. The primary bevel should be ground to 25 degrees. A secondary micro-bevel of 30 degrees improves edge retention. Use a honing guide to maintain a consistent angle. After sharpening, strop the blade on a leather strop loaded with compound. A properly sharpened blade should shave hair.

The cap iron, also known as the chip breaker, is the metal piece that sits on top of the blade. It is adjusted to be very close to the cutting edge, typically about 1/32 of an inch. This close setting breaks the wood shaving as it curls, preventing tear-out. Adjusting the cap iron takes practice, but it is essential for working with figured woods.

The depth adjustment knob controls how much wood the plane removes. A good starting point is a very light cut. You can always take a deeper cut, but it is difficult to undo a too-deep cut. The lateral adjustment lever is used to align the blade so that it protrudes evenly across the sole. An uneven blade will produce a stepped surface.

Maintaining your hand plane is straightforward. After each use, wipe the blade with a light coat of camellia oil or machine oil to prevent rust. Store the plane on its side or on a wooden rest to protect the blade. Sharpening the blade should be done whenever you feel it starting to dull. A dull plane is frustrating to use and produces rough work.

In conclusion, a well-chosen and properly set up hand plane is a pleasure to use and produces work of exceptional quality. Start with a No. 4 smoothing plane and a block plane. Learn to sharpen and adjust them. These skills will serve you for a lifetime.
