AI summary

Paul Sellers shows how to cut precise, stopped grooves without a plough plane or power tools. Mark the groove with a mortise/marking gauge and deepen the lines with a knife; optionally superglue a temporary fence to guide the saw. Saw both walls to depth with a tenon saw, then chop and lift the waste with a chisel (bevel down), finishing the floor with a simple “poor man’s router” made from scrap wood and a chisel. He emphasizes grain awareness, quick superglue-and-accelerator setup, optional depth control, and the satisfaction of quiet, dust-free hand work. Tools: gauge, knife, 1/4" and 3/16" chisels, mallet, tenon saw; includes links to a companion video and his router-plane how-to.

What hand-tool approach do you use for grooves when you don’t have a plough plane—and would you try the poor man’s router on your next project?

This blog post is of course free, but you might want to watch the video we made and join your fellow enthusiasts. Here is the link. If a picture does paint a thousand words, then a video could do more. Enjoy the following:

Ploughless Ploughing Grooves
Hard to imagine so little wood can give back so much. Imagine, four lifetime tools designed and made to last for 150 years of full-time daily use from a few scraps of wood that. If you bought it, the wood might cost no more than £8. Oh! Interesting. You didn't need more than the real power of hand tool woodworking. Not a machine in sight. Imagine.

So you don't own a tablesaw or a so-called power router. If you're like me, you don't want these space hogging screaming banshees anyway. Thriving without them truly improves your self high-demand life. The small cluster above would take me a couple of hours of machine-free woodworking, I get the ideal exercise to renew and maintain my whole body and mind and my happiness is quite complete. No need to make a bunch of jigs, buy in an array of support supplies or rely on dust and chip extraction, wear dust masks, eye and ear protection for any of it and I could listen to a podcast or music as well.

Ploughless Ploughing Grooves
We don't all own a plough plane to plough with, and sometimes we need a precisely made groove, yet we'd rather do it using our own hands and work totally in self-powered ways throughout our days. I have dug out many a recessed channel in wood without a plough plane close to hand.

I know not everyone owns a plough plane and when you need a short length of groove or channel in wood you might not want the cost and trouble of buying one in. I've made this ploughless groove often enough through the years because not all grooves go all the way through for different reasons. Generally, plough planing grooves rely on the groove going all the way through. Take your time and follow the steps, and it will work for you too. Here is the video but hope you'll stiil read through this post. Enjoy!

Ploughless Ploughing Grooves
Using your imagination, use this picture to inspire you. Your hands pick up a quarter-inch chisel. You've sawn the walls with a tenon saw, and all you are doing now is tap, tapping a few chops in between the two kerfs to split-separate the fibres with or along the grain. Keep reading!

Step One:

It's best to set the mortise gauge to the width you want and to mark the parallel lines in the place you need them. This process parts the surface fibres, which is just a good and practical strategy.

Ploughless Ploughing Grooves
If you do not have a mortise gauge, just use a marking gauge, working from both sides of your workpiece.

Step Two:

With a sharp, pointed knife, carefully define the walls of the groove slightly deeper by pulling the knife point into the gauge lines to cut deeper into the fibres. Watch for grain change in direction and counter any straying grain intent on taking you off course. Sometimes you simply need to change direction 180º and go the opposite way. Sometimes you simply lower the angle so the blade rather than the point severs the fibres.

Ploughless Ploughing Grooves
Deepen the gauge lines with a pointed knife, ready for sawing. You could install the guide first if you want to. Often, I do not use any fence, and that is why you don't see me using it here.

Step Three:

I suggest you do this, though I often do not; Superglue a strip of wood right on the gauge line so that saw cuts are with thin the groove area. Three tabs of glue dots sped up with accelerator secures the strip firmly enough to work to with the saw strip in two seconds. . .

. . . But I added one for this article. The simplest and most practical way to attach a one time or temporary fence to guide tools like saws and chisels is to use clamps, but that is not always practical on narrow edges. I usually use superglue with a squirt or two of accelerator. This accelerator sets the glue in under five seconds, and two or three dots will usually be enough.

Adding a brief and short burst of accelerator corresponding to the superglue blobs means that, when setting the guide to the workpiece, the set is almost instant, and you are ready to register your tools to it.

No margin, just tight to the line, works perfectly well. The saw plate rides to the guide. If the depth is critical, you can clamp a depth guide to the saw plate itself so that the saw stops cutting when the depth guide hits the surface of the long guide you are working to. I probably would just go for a guesstimate depth.

Step Four:

With a mid-sized tenon saw (12" or so), start at the point furthest away from you and saw with short strokes, using the point of the saw inside your gauge line, and moving backwards until all of the teeth engage. With subsequent strokes, lowering the saw as you go, saw down as far as your intended groove depth.

Ploughless Ploughing Grooves
The saw kerf of my tenon saw deepens the walls to depth with a few strokes. My 5mm depth on a short length of ten inches takes only ten strokes, and the end result is a pristine, to-the-line sidewall to any groove.
Ploughless Ploughing Grooves
A swift strike splits the glue line right down the middle of the hardened glue, but not usually damaging the wood. Residue is easily chiselled away with no harm to the cutting edge of the tools. Both separated pieces can be used many times over.

Step Five:

With both walls sawn down to depth, use an appropriate sized chisel to develop stop cuts as you might say a mortise. Work bevel down and backwards. This will part the fibres by short split-cuts that can then be removed with jab-cuts to remove the bulk of the waste

Ploughless Ploughing Grooves
We call these chop cuts. Work from the point furthest away from you and come backwards. You will gauge the distance between chops according to your wood type. They all split differently. Even so, 6mm apart is plenty and at those short distances the splits come quickly. By this, we rely on the characteristic, long-grain splitability of grain to split longwise along the grain. The waste wood is easily lifted away with a few jabs with the chisel bevel-down.
Ploughless Ploughing Grooves
Here is the fast result of bevel-down jabbing to lift the fibres away and ready for the poor man's router plane (below) to level the field.

Step Six:

A simple hand plane router can be made from any odd scrap of wood and a suitably sized chisel. In my case, the groove is 1/4" and I installed a 3/16" chisel through a tight-walled hole by tapping it into place. With the first strokes in the groove it will usually feel a little jarring, but the jaggedness can be countered by tilting forward to reduce depth of cut. Subsequent cuts at a lower angle remove material smoothly.

Simple solutions help to make woodworking both enjoyable and doable in the zone. This is the original Paul Sellers' Poor Man's Router. Go to this link to watch the simplicity of making and using one. This one I am showing above is a small version. For my blog post, go here. Notice that the bevel of the chisel faces down, not up. It makes a huge difference to the finish. Oh, ignore the groove. It was a scrap.

Although this usually delivers a perfect recess, sometimes it might not be as smooth as you want, but the bottom will establish a level you can work with just fine without compromise. It's important to tilt the plane forward in the opening strokes. You can control the depth of cut this way, and it saves incremental shallow setting to speed up the process.

The result is good, and especially in close-grained beech.

Ploughless Ploughing Grooves
My end result is as perfect as it gets, and that's because grain orientation aligns with the stars. The advantage of routing the bottom with a hand router plane like this one is the ability to reorient the plane accordingly.

Tools used:

Mortise or marking gauge

Knife. I use a Stanley 0-10-598 folding pocket knife

A 1/4" and 3/16" bevel-edged chisel

Chisel hammer or mallet

Tenon saw
