Luban Hand Planes

Luban hand planes can be used for flattening timber, straightening edges, reducing boards to final dimensions, smoothing surfaces and making precise fitting adjustments. The exact application depends on the type and length of the plane. Bench planes are commonly used for stock preparation and surface finishing, while block and specialist planes are useful for smaller trimming and joinery tasks.

A jack plane is often a practical first bench plane because it can perform a broad range of woodworking tasks. It can remove material during initial preparation, flatten and straighten timber and, when fitted with a finely sharpened blade and set for a light cut, perform relatively fine surface work. A block plane is also a useful addition for trimming, chamfering and smaller fitting jobs.

A smoothing plane has a relatively short sole and is primarily intended to take fine shavings from an already flat or nearly flat surface. A jack plane is longer and generally more versatile, making it suitable for stock preparation, flattening and general bench work. The shorter smoother follows local variations more readily, whereas the longer jack plane bridges smaller depressions and is therefore more useful during the flattening process.

A jointer plane is particularly useful for flattening larger workpieces and producing long, straight edges. Its long sole references a greater area of the timber, helping it remove high spots rather than simply following an uneven surface. This makes a jointer plane especially useful when preparing board edges for accurate joints or flattening long furniture components.

Block planes are compact tools commonly used for trimming components to fit, working end grain, removing sharp corners, creating small chamfers and performing other one-handed planing operations. Their size makes them convenient for work that would be awkward with a full-sized bench plane. A sharp blade and light cut are particularly important when planing end grain.

Even when a new plane iron arrives with a prepared cutting edge, honing it to a fine edge before serious woodworking is good practice. Hand plane performance is highly dependent on blade sharpness. A properly honed iron requires less effort, produces cleaner shavings and is better able to deal with difficult grain. The cutting edge should then be re-honed periodically rather than waiting until it becomes noticeably blunt.

Begin with the cutting iron retracted and gradually advance it until the blade just begins to take a shaving. Use the lateral adjustment to make the cutting edge project evenly across the sole, then make very small depth adjustments until the desired shaving is achieved. For final smoothing, a sharp iron, shallow cut and appropriately set mouth can help produce thin, consistent shavings and minimise tear-out.

First identify the direction of the grain and, where possible, plane with it rather than against it. Keep the blade extremely sharp and use a light cut as the surface approaches its finished condition. Appropriate plane setup can further support the fibres immediately ahead of the cutting edge. Figured timber and reversing grain may require particularly fine cuts, careful changes in planing direction or alternative finishing techniques in difficult areas.

Keep the blade sharp, clear shavings and dust from the plane after use, and protect exposed metal surfaces from moisture and corrosion. A light application of a suitable rust-preventative can help when the plane is stored, particularly in humid workshops. Periodically inspect the blade, chipbreaker and adjustment mechanisms and remove any resin or debris that could interfere with accurate adjustment.
