The Forbidden Technique That Flattens Any Board Perfectly. (Tool Companies Are Furious)

Added: 2026-06-08

[00:00:00]Two sticks of wood, no batteries, no calibration, no digital readout. Just two straight parallel sticks placed at opposite ends of a board, and they detect twist more accurately than a $2,000 machine jointer.

[00:00:13]Every chair, every table, every cabinet, every door built before 1850 was flattened with this method.

[00:00:21]Not one power tool involved.

[00:00:23]We did not abandon it because something better came along. We abandoned it because you cannot sell a monthly blade subscription for two sticks of scrap wood. This is the story of winding sticks, the oldest and most precise flattening technique in woodworking history, and the machine industry that buried it.

[00:00:41]The archive opens in London, 1678.

[00:00:45]A printer and polymath named Joseph Moxon publishes the first comprehensive trade manual in the English language. He calls it Mechanic Exercises.

[00:00:55]In its pages, Moxon describes the daily work of the joiner's shop with startling precision. He documents the tools, the sequences, the logic behind every operation. And at the foundation of every project, before any joint is cut, before any surface is finished, he describes the act of flattening stock with a hand plane guided by two parallel sighting sticks. He calls the process winding.

[00:01:19]The sticks themselves have no formal name yet. They are simply part of the craft, as fundamental as the bench itself. But Moxon was not recording something new. He was documenting a practice already ancient by the 17th century. Roman joiners working in Pompeii before 79 AD used sighting methods to true lumber by hand. Medieval European guild joiners passed the technique from master to apprentice across centuries. No written manual required.

[00:01:47]In Japan, the Miyahiku temple carpenters developed their own version using Dyna Oshi sticks to read surfaces with extraordinary precision, techniques still taught in Kyoto today.

[00:01:58]Across every woodworking culture on earth, the same principle emerged independently.

[00:02:03]Two reference edges, two eyes, and the geometry of light revealing what fingers alone could never feel.

[00:02:11]The technique survived because it works on a principle that no machine has ever replicated.

[00:02:16]When you place two parallel sticks across a board, one near the front edge and one near the back, then sight across them from one end, your eye becomes a precision instrument. Any twist in the board causes the far stick to appear tilted relative to the near stick.

[00:02:32]And here is what makes this method so powerful. The farther apart the sticks are placed, the more the twist is amplified visually.

[00:02:39]On a board 3-ft long, a twist of just 1/32 of an inch, a distortion so slight you could never detect it by touch, becomes a clearly visible angular offset between the two sticks. Your eye reads it instantly. No measurement required, no dial indicator, no digital sensor.

[00:02:56]The geometry does the work.

[00:02:59]Now, compare this to what a machine jointer actually does. A power jointer references only the bottom face of the board against its bed. It shaves the top face relative to whatever the bottom is doing. If the bottom face has a cup, a bow, or a twist, the machine transfers that distortion directly into the top face. It does not detect twist. It does not correct twist. It simply passes the board through and hopes for the best.

[00:03:25]A hand plane guided by winding sticks does the opposite. It reads the actual surface in three dimensions, along the length, across the width, and diagonally corner to corner, and removes material only where the high spots exist.

[00:03:40]The operator is the sensor. The sticks are the display.

[00:03:45]And the plane is the correction tool, guided by real-time visual feedback that no motorized machine can match.

[00:03:52]The sequence is specific and it has not changed in centuries. You begin with a number five jack plane fitted with a cambered iron. Meaning the blade is ground with a slight curve across its width. This curved edge takes aggressive scooped cuts without leaving sharp ridges. You read the winding sticks.

[00:04:10]They show you which corners are high.

[00:04:13]You plane diagonally across those high corners first working from one end of the board to the other in skewed strokes.

[00:04:20]This is not random. Diagonal strokes let the cambered iron shear across the grain fibers efficiently. Removing material fast where the twist is worst. Once the major twist is broken, you switch to traverse planing.

[00:04:34]Driving the jack plane across the width of the board perpendicular to the grain.

[00:04:38]This knocks down high spots across the face and brings the surface closer to a single plane.

[00:04:44]You check with the winding sticks again.

[00:04:46]You check with a straight edge laid along the length, across the width and diagonally. Three planes of reference.

[00:04:53]When the winding sticks show parallel and the straight edge shows no light beneath it in any direction, you bring out the number seven jointer plane.

[00:05:02]This is a long-bodied plane, 22 inches of sole that bridges low spots and shaves only the peaks.

[00:05:09]You take light straight passes along the grain.

[00:05:12]The length of the sole enforces flatness the way a short plane never could.

[00:05:18]When the seven produces full length, full width shavings of uniform thickness, the board is flat. Not machine flat.

[00:05:26]Actually flat. Verified in three dimensions by your own eyes and a method proven over millennia.

[00:05:34]This was not a specialist technique.

[00:05:35]This was not the domain of master craftsmen working in isolation.

[00:05:39]Before 1850, every working joiner in the western world flattened stock this way.

[00:05:44]Every single one.

[00:05:47]The Shaker communities of New England built furniture so precisely fitted that pieces crafted in the 1790s still sit flat on modern surfaces today.

[00:05:57]You can visit Hancock Shaker Village in Pittsfield, Massachusetts and see tables, desks, and cabinets that have not been refinished or re-flattened in over 200 years.

[00:06:07]Every surface was trued with winding sticks and a hand plane. In London, the workshops producing Chippendale and Hepplewhite furniture relied on the same method.

[00:06:16]Apprentices spent their first years learning nothing but stock preparation, reading twist, traversing faces, and chasing flatness with a jack plane and a jointer.

[00:06:26]In the Royal Navy dockyards at Portsmouth and Chatham, shipwrights flattened massive oak timbers for warship construction using oversized winding sticks and long trying planes.

[00:06:37]The decks of HMS Victory, Lord Nelson's flagship at Trafalgar, were fitted from timber flattened entirely by hand.

[00:06:45]In Japan, the tradition ran even deeper.

[00:06:48]The miyadaiku who built the temples of Nara and Kyoto flattened timbers of Japanese cypress using hand planes and sighting techniques so refined that joints fitted without any adhesive held for over a thousand years. The Horyuji Temple Complex in Nara, built in the 7th century, contains the oldest surviving wooden structures on Earth.

[00:07:09]Every timber was flattened by hand.

[00:07:11]Every joint was read by eye. This was the universal standard.

[00:07:16]Not because there was no alternative, but because nothing worked better.

[00:07:20]Before we go deeper into what happened next, I want to mention something.

[00:07:25]I have spent years compiling the techniques we are uncovering in these investigations, and I put the best of them into a book called The Forgotten Workshop.

[00:07:34]100 lost woodworking skills that corporations tried to erase.

[00:07:38]171 pages of forgotten wisdom.

[00:07:46]Now, let us follow the money.

[00:07:48]The power jointer appeared in American factories in the 1860s.

[00:07:52]Early models were massive belt-driven machines designed for industrial lumber mills, not small shops.

[00:07:59]For decades, hand methods and machine methods coexisted. The factory used power tools for speed. The craftsman used hand tools for precision. Nobody confused the two. The shift began after World War II. The American consumer economy exploded. Power tool manufacturers saw a market not in professional shops, but in home garages.

[00:08:21]Delta, Rockwell, Craftsman, and later Jet, Grizzly, and DeWalt began producing benchtop jointers priced for hobbyists.

[00:08:29]A 6-in benchtop jointer could be sold for $400 to $800.

[00:08:34]An 8-in model ran $1,000 to $2,000, and every machine created a cascade of secondary purchases.

[00:08:42]Replacement blades every 6 to 12 months, $15 to $40 per set. A thickness planer to complement the jointer, another $300 to $700.

[00:08:53]A dust collection system, another $200 to $500.

[00:08:57]Possibly an electrical panel upgrade to run the larger machines, another $500 to $1,000.

[00:09:03]A single entry-level jointer purchase could generate $1,000 to $3,000 in follow-on spending within the first 2 years. And the blades keep needing replacement, the belts keep wearing, the bearings keep failing.

[00:09:17]The machine itself is designed to be replaced within 10 to 15 years.

[00:09:21]Now, consider the alternative. A used number five Stanley jack plane sells for $30 to $75.

[00:09:28]A used number seven Stanley jointer plane sells for $60 to $150.

[00:09:34]A pair of winding sticks can be made from scrap hardwood in an afternoon. A good straight edge costs $20 or nothing if you joint one yourself. Total investment, $50 to $150.

[00:09:47]No blades to replace, no belts to wear, no dust collection required, no electricity consumed, no ongoing cost whatsoever. A well-maintained hand plane lasts not 10 years, not 20 years, but centuries.

[00:10:03]There are Stanley Bailey planes from the 1870s still in daily use in professional shops today.

[00:10:09]This is the economic problem. A customer who buys a hand plane and learns to use winding sticks never comes back. The sale is over. The revenue stream is dead. A customer who buys a benchtop jointer comes back for blades, for planer upgrades, for dust collection, for electrical work, for the next machine, and eventually for the replacement of the first machine.

[00:10:32]The lifetime value of the machine customer is 10 to 50 times greater than the hand tool customer.

[00:10:38]So, the industry did what industries do.

[00:10:40]Trade schools shifted curriculum toward machine operation. Woodworking magazines filled their pages with power tool reviews and advertisements. Big box stores dedicated aisles to motorized jointers and planers and stocked not a single hand plane.

[00:10:55]The self-reinforcing cycle locked in.

[00:10:58]New woodworkers never see a hand plane in the store, never learn the technique in school, never encounter winding sticks in any mainstream publication.

[00:11:07]They assume machines are the only way because machines are the only thing presented to them, and they spend accordingly.

[00:11:14]The hidden cost of this replacement goes beyond money. A 6-in benchtop jointer cannot flatten a board wider than 6 in.

[00:11:22]Most furniture projects require panels of 8, 10, or 12 in. The jointer becomes useless for the most common task it was purchased to perform.

[00:11:31]The solution sold by the industry is to buy a larger jointer, 8 in for $1,000, 12 in for 2,000 or more.

[00:11:39]The upsell is built into the limitation of the entry-level product. But, the problems go deeper.

[00:11:45]Machine jointers produce snipe, a gouge depression at the leading and trailing edges of every board caused by the cutter head catching the wood as it enters and exits. Snipe wastes material.

[00:11:56]It requires extra length on every board, which means buying more lumber, which means more money flowing to the supply chain.

[00:12:02]A hand plane produces no snipe.

[00:12:05]Zero. Machine jointers are loud.

[00:12:09]85 to 100 decibels, the threshold for hearing damage. They produce fine dust at high velocity, the particle size most dangerous to lung tissue. They require guards, push blocks, and careful technique to avoid catastrophic hand injuries.

[00:12:24]The United States Consumer Product Safety Commission reports thousands of jointer and planer injuries annually.

[00:12:30]And here is the irony that cuts deepest.

[00:12:32]The most common complaint on woodworking forums today is that boards come out of the jointer and planer still not flat.

[00:12:40]The machine jointer references only the bottom face. If the operator does not understand twist, does not know how to read a board in three dimensions, the machine simply produces a board that is uniformly thick, but still twisted. The skill the machine was supposed to replace turns out to be the skill the machine requires to function correctly.

[00:13:01]Woodworkers who never learn to read twist cannot get flat boards from any tool, powered or not. The knowledge was not optional. It was foundational. And it was stripped from the curriculum to sell machines. But, the technique survived. It survived because people who value precision over convenience kept it alive. Paul Sellers, a British-American woodworker and educator, has spent decades teaching hand tool woodworking through free online videos and courses.

[00:13:28]His flattening method is identical to what Moxon described in 1678.

[00:13:32]Winding sticks, a jack plane, a jointer plane, and three planes of reference.

[00:13:38]His students number in the hundreds of thousands worldwide.

[00:13:42]Chris Schwarz, author and editor, co-founded Lost Art Press and has published extensively on the hand tool methods that predate industrial woodworking. His books, including The Anarchist's Tool Chest, have introduced a generation of woodworkers to the reality that a $50 hand plane outperforms a $1,000 machine when the operator knows how to read a surface.

[00:14:03]Lie-Nielsen Toolworks in Warren, Maine, still manufactures hand planes to tolerances that match or exceed anything produced in the 19th century.

[00:14:13]Their number seven jointer plane is a precision instrument capable of producing surfaces flat to within 1/1000 of an inch.

[00:14:21]Wood River, the budget-friendly line from Woodcraft, has made quality hand planes accessible to beginners at prices below $100. In Toronto, the Unplugged Woodshop operates as a hand tool only teaching studio, proving to every student who walks through the door that machines are not required for professional quality work. In Japan, the tradition never broke.

[00:14:43]The Takenaka Carpentry Tools Museum in Kobe preserves the history of hand tool woodworking stretching back over a thousand years. Japanese woodworking schools in Kyoto still teach apprentices to flatten timber by hand as the first and most essential skill, exactly as it was taught in the 7th century.

[00:15:01]The knowledge persists because it is embedded in every structure it ever created. Every antique table that still sits flat after two centuries is a testament.

[00:15:11]Every Shaker cabinet, every Japanese temple beam, every hand-built ship timber carries the evidence in its surface. Run your fingers across a board flattened by a hand plane.

[00:15:21]200 years ago and you can still feel the subtle scallop texture of overlapping blade strokes. That surface is the signature of a human hand reading twist, correcting error, and achieving precision through skill, not through machinery. This is the pattern that repeats across every investigation we conduct. Techniques that enable self-sufficiency are replaced not because they fail, but because they succeed without corporate dependency. A method that costs $50 and lasts forever is an existential threat to an industry that needs you to spend $2,000 and come back every year.

[00:15:58]The replacement is never about quality.

[00:16:00]It is about revenue. And when the supply chain breaks, when the power grid falters, when the next machine breaks down in a garage 3 years after purchase, the two sticks of wood will still work.

[00:16:12]They require no electricity, no firmware update, no replacement parts. They require only a pair of eyes and the knowledge of what to look for.

[00:16:20]That knowledge is older than any corporation on Earth and it will outlast every one of them.

[00:16:26]They buried it because it worked too well.

[00:16:29]Because a pair of sticks that detects twist to 1/32 of an inch does not need to be replaced. Because skill that lives in your hands cannot be sold in a store.

[00:16:38]But it survived and now you know. If you want 100 more techniques like this, the Forgotten Workshop has them. 171 pages of skills they tried to erase. Scan the QR code or hit the link in the description. Subscribe to Heritage Woodcraft.
