Infringe upon the rights of no one. Borrow no tool but what you will return according to promise. Take no wood, nor anything else but what belongs to you – and if you find anything that is not your own, do not hide it away, but report it, that the owner may be found.Brigham Young
In this post your humble servant will offer some advice that, if followed, will save Gentle Readers time, money, and wear and tear on their valuable woodworking tools. These are not original techniques; I stole them long ago from professional woodworkers in Japan. Wise Gentle Readers will be as bold.
Inspection & Questions
Before we go any further, Gentle Reader, do me a favor. Check the soles of your steel planes. Unless they haven’t been used much, you will probably discover scratches, some of which may even be quite deep. Do you think whatever made these scratches might also have dulled the cutting edges of your planes at the same time?
What could have possibly created these scratches? Have iron pixies been using your beautiful planes to shave bricks?
Unless you have a serious pixie infestation, it probably wasn’t anything as large as a brick, but rather tiny particles in or on the wood you have been cutting. Could these vicious, hard particles have grown naturally inside the tree the wood you are using came from? Is there anything that grows naturally inside a tree that is harder than a plane blade’s cutting edge and big enough to cause such deep scratches? Perhaps these abrasive particles were maliciously concealed inside the growing tree by compadres of the shambling horde of 6-armed, green-skinned, Fanta-guzzling aliens that follow me everywhere?
Or could the damage have been caused by nails, screws or staples left in the wood? Perhaps. Pixie toenail clippings? Happens more often than we realize. Tiny fragments of a divorce lawyer’s heart? Maybe, but such particles are rarer than honest politicians and tougher than stellite. No, it’s more likely the culprit is something harder and more insidious than even Murphy’s pointy purple pecker, a substance all around us, one we often ignore.
Politics and journalism aside, we live in a dusty, dirty world, and although the steel in your tool blades is very hard, ordinary dust and dirt contain plenty of particles much harder. I guaran-frikin-tee you that collision with even a small particle of mineral grit embedded in the surface of a piece of wood can and will damage a blade’s cutting edge.
You may believe the damage is minimal and of little concern, but every time your blade becomes dull, you must resharpen it. Every sharpening session costs you time pushing the blade around on stones, time not spent cutting wood. And sharpening turns expensive blades and stones into mud. This is time and money lost forever.
And the abrasive action of dirt and grit embedded in wood is not hard on just chisel blades, plane blades and the soles of steel planes, but is even harder on sawteeth and wooden planes.
The damage is not limited to just your handtools either. Take a closer look at the steel tables of your stationary equipment such as your jointer or tablesaw. Unless they are new, you will find scratches. Has that pervert Murphy been smokin dope and humpin sumpin on your jointer’s bed when you weren’t looking?
Nay, Gentle Reader, supernatural causes aside, and unless you have been dismembering the bodies of divorce lawyers in your workshop, these scratches are clear evidence that the wood you’ve been working is neither as clean as it looks, nor as clean as it should be. You’ve gotta do something about that.
Ruba Dub Dub
So what can you do? Strange as it may seem, the simplest and surest way to get rid of dirt and grit is to follow your mother’s instructions about the cleaning the bathtub: Simply wash it with soap, water and a scrub brush, followed by a rinse.
Bet you never thought of washing wood before have you?
The idea is to wet, scrub and quickly rinse the dirt and grit off the wood, not to make the wood soaking wet, so none of that “rinse and repeat” nonsense, and don’t get carried away with the hose. A bit of dishwashing soap, washing soda or borax mixed in the water bucket will help lift out dirt and grit.
Don’t forget to pat each board down immediately afterwards with clean rags to remove surface water. Then separate each board, stand it on stickers on-end, or rest it on-edge, and allow time and circulating air to dry it out of the sun.
Remember to wet both sides of each board to minimize warping. And don’t soak a lot of water into the ends.
Disclaimer: Rubba-dubdub is not well suited for thin material or laminated wood products that might easily warp, or if you are in a hurry, or if you lack adequate space to properly air-dry the wood.
Whether you wash the wood with water or not, be sure to do at least the following two steps on every board before you process it with your valuable tools.
Scrub Scrub Scrub
If you can’t wash the boards, use a steel wire brush to dry-scrub all the board’s faces both with and across the grain. Yes, I know it makes the surface rougher. Tough pixie toenails. Scrubbing with a stiff steel brush is extremely effective at removing dust, dirt, embedded particles of grit, and even small stones from long grain. Give it a try and you will both see and smell the dirt and particles expelled. Pretty nasty stuff sometimes.
Saw Saw Saw
Second, and this is supremely important, before planing a board either by hand or using powertools, saw 2~3mm off both ends. This is why you have that circular saw with the carbide-tipped blade. If you can’t do that, at least use a steel block plane, drawknife, or other tool to chamfer all eight corners of the board’s ends to remove both surface dirt and embedded grit.
This step is critical because grit and even small stones frequently become so deeply embedded in endgrain that even a steel brush can’t dig them out. But sure as God made little green apples, Murphy will place them directly in the path of your plane blade.
If you do these things, your tools will thank you over many years with abundant chips, shiny shavings and cheerful little songs. I sincerely promise.
