Trimming a timber skirting return is a small job, but it exposes weak hand tools quickly. The cut is short, often close to a wall or door lining, and the grain can change at the corner. A plane that works well on a long board may be awkward here. For most carpenters, the best choice is a sharp block plane, supported by a smaller trimming plane or shoulder plane for the last few millimetres.
What the Plane Needs to Do
A skirting return is the short end section where the profile turns back into a wall, door lining, or adjoining piece. You may need to reduce its length, shorten the return, or create a clean bevel before fitting it. The work is usually done on a piece between 12 and 25mm thick, with only 10 to 50mm of end grain or edge to remove.
This calls for control rather than cutting capacity. The plane should be easy to register against a narrow edge, comfortable to use one-handed, and capable of taking a very fine shaving. A mouth that closes down to roughly 0.5mm helps prevent breakout, while a sharp iron matters more than an expensive body.
For general trimming, a low-angle block plane is the most useful starting point. Its low bedding angle handles end grain well, and its compact body fits into corners where a No. 4 bench plane does not. A standard-angle block plane is also suitable for long grain, painted softwood, and small fitting adjustments.
The Best Plane Types for Skirting Returns
| Plane type | Best use | Advantages | Limitations |
|---|---|---|---|
| Low-angle block plane | General trimming and end grain | Compact, controllable, good on end grain | Short sole can rock on very narrow work |
| Standard block plane | Long-grain edges and painted timber | Versatile and usually cheaper | Less effective on difficult end grain |
| Small shoulder plane | Cleaning a rebate or tight return | Blade reaches the edge of the sole | More specialised and less comfortable for bulk removal |
| Spokeshave | Curves and shaped profiles | Useful on rounded or irregular details | Not the first choice for straight returns |
| Rasp or file | Final adjustment in awkward corners | Cheap, forgiving, and good for tiny corrections | Leaves a rougher surface than a plane |
A small shoulder plane is worthwhile when the return includes a rebate or when the cut must run right into a corner. Because the iron extends across the full width of the sole, it can remove the last sliver that a block plane leaves behind. It is not necessary for occasional domestic work, though. A sharp chisel and a block plane cover most skirting repairs.
Buying Advice and Sensible Alternatives
Look for an adjustable-mouth block plane with a blade at least 35mm wide. A heavier cast-iron body tends to stay steady, but a lighter plane is easier to control in a confined position. The adjustment mechanism should move the blade without sideways play. Avoid tools with a blade that rocks when the lever cap is tightened; that makes a fine setting frustrating.
A premium plane is useful if you trim hardwood, work on site every day, or want reliable adjustment straight from the box. For occasional softwood skirting, the cheaper option is fine if the sole is reasonably flat and the blade can be sharpened properly. Many budget planes arrive with a dull or poorly honed iron, so allow time for setup rather than judging the tool immediately.
If you are buying one tool only, choose a quality adjustable block plane. Add a small shoulder plane only when you regularly fit rebated mouldings or need to trim into stopped corners. A sharp woodworking chisel set is often a better second purchase than another plane.
How to Trim a Return Cleanly
Mark the cut with a sharp pencil or marking knife. Measure from the face side and mark both edges, then carry the line across the end. If the cut is close to finished work, leave 1mm to 2mm for planing rather than trying to hit the final line with a saw.
Support the skirting firmly on a bench. Place scrap timber under the piece so the plane can exit into support rather than lifting fibres from the far edge. Clamp the work close to the cut, but do not crush softwood with excessive pressure. A bench hook is useful for short sections and avoids chasing the work across the bench.
Plane with the blade set for a shaving around 0.1mm thick. Start with the toe of the plane on the work and apply pressure over the front, then gradually move pressure to the rear as the stroke finishes. On end grain, shorter strokes and a slightly skewed plane reduce the cutting angle and limit breakout. If the grain tears, reduce the cut, skew the plane more, or work from both ends toward the centre.
Check the mark frequently with a combination square. Stop when the sole just kisses the waste side of the line; trying to remove the final fraction by force commonly produces a hollow or rounded end. For a return that meets a wall, a tiny back bevel of about 1mm can hide an imperfect corner and prevents the visible arris from breaking during installation.
Common Failures to Avoid
The most common mistake is using a plane with a dull iron. It crushes the end grain, demands too much pressure, and makes the short piece move. Hone the edge until it cleanly shaves end grain; a practical working bevel is about 25 to 30 degrees, depending on the blade and plane design.
Another failure is planing across unsupported end grain. This causes spelching at the exit edge. Add a sacrificial block, plane from the outside toward the middle, or leave the last 2mm for a chisel. Do not use a large bench plane simply because it is available: its long sole can bridge the work and make a short return difficult to control.
For most skirting returns, a well-set block plane is the right balance of price, accuracy, and usefulness. Buy the better plane if it will see daily site work; otherwise, spend the saving on sharpening equipment, a reliable square, and proper support for the timber.
