Chris will be presenting in Colonial Williamsburg this weekend and I’m up to my hairline in work – so we asked Andy Glenn, author of “Backwoods Chairmakers” (the most recent book release from LAP) if he’d like to take a Saturday stint of answering your woodworking questions. Reader, he said yes!
Andy is a fount of knowledge on post-and-rung chairs (particularly those from the Appalachian region), but he’s well-schooled (and not just metaphorically!) in all areas of woodworking. He trained at the North Bennet Street School (NBSS) before working in furniture repair shops, cabinet and furniture shops, and a wooden boat repair shop. For more than a decade, he’s taught continuing education classes at NBSS and has been a guest instructor in the Cabinet and Furniture Making program at his alma mater. For several years, he was also supervisor of the Woodcraft Program at Berea College Crafts and ran the Woodworking School at Pine Croft.
So get those questions ready for Saturday! As always, the post will go live at around 7 a.m., and comments will close at 5 p.m. – and there may be a lag between your questions and Andy’s answers (I believe he has an ice skating commitment mid-day).
For more than 200 years, chairmakers in Appalachia built ladderbacks to sell to neighbors and the occasional tourist. It was a tradition that was handed down through generations. But with the rise of furniture factories and mechanization, woodworker Andy D. Glenn wondered if there were any traditional chairmakers left. So he set off into the mountains with a camera and a tape recorder. There, he found many still working the craft – some by hand, and others who have added machines to their workshops.
Part travelogue, part profile and part how-to, “Backwoods Chairmakers” explores the tradition of this enduring form. Glenn takes you inside the shops of more than 20 makers, with photos and personal interviews about their lives and techniques.
Then, Glenn shows you how to make a post-and-rung side chair and rocking chair using the traditional techniques explored in the book.
“I come from a long line of good ol’ boys and strong women who were yeoman farmers first and foremost, and makers out of necessity. They made chairs, furniture and wagons, and were blacksmiths and toolmakers, carpenters – both rough and finish – sawyers and farm-implement makers. One grandfather started out in the family wagon business after completing the eighth grade, and by the early 1930s they were out of business as the carriage went horseless.”
— Lyle Wheeler
The Appalachian ladderback goes by different names, depending on the region and the maker’s preference. “Post and rung” is the umbrella term used to describe these chairs, but during my travels only a single chairmaker called it that. Post and rung refers to the construction method: vertical posts receive horizontal rungs. And it refers to any chair design of similar fashion, whether made in Appalachia or elsewhere.
Instead, I heard the chair called a split bottom, common chair, mule ear, settin’ chair, ladderback, hickory bottom, woven chair or mountain chair. Or, as one maker put it, “It’s simply a chair.” The terms all refer to the same style: rungs below, some of which create a frame for a seat, and slats above to support the back. It’s a simple form, familiar to anyone in the region, with each chairmaker or shop adding distinctive details.
It’s also a form that requires only a few tools. A skilled chairmaker could fashion a chair with as little as an axe, bit and brace and a pocketknife. This made the form ideal in the mountains of Appalachia. Drew Langsner (Chapter 8) describes the form as the first chair an Appalachian family would add to their home, “…from no chairs to this chair.” It was the evolutionary first step.
There is no single definitive Appalachian chair style, though there are characteristics found on chairs throughout the region. For each example of a characteristic, there are multitudes of counter examples. A typical Appalachian mountain chair uses a combination of these characteristics, with each chair style determined by the maker’s preferences and the style of the region.
One defining characteristic of an Appalachian chair is the restrained use of ornamentation. The vertical posts, when turned, may have a few details left by the turner, but most shaved chairs are left plain. The “foot,” or lower posts near the floor, frequently taper toward the end to give a more delicate appearance. The back posts might have a finial – turned chairs are more likely to possess the finial than shaved ones.
The back posts are either straight or bent. The bend adds considerable comfort to the chair, and Appalachian chairmakers claim the bent back posts are their distinct contribution to the ladderback form. The bend comes from a natural wind in a tree, or, most frequently, from the chairmaker steaming or boiling the back posts before bending them on a form.
The last common characteristic is the woven seat, often from hickory bark, though chairmakers also used seagrass, flat reed, paper cord, cotton tape or corn shuck (though I didn’t find a contemporary maker using corn shuck). Hickories are abundant in Appalachia. Though collecting the bark is hard on the back and hands, the material can be harvested within a maker’s community.
The Chair’s Joinery The chair’s durability, essential to its long-term success, is determined by the post-and-rung joinery. Round joints are frequently derided within woodworking circles for wiggling loose and failing. That derision is not without merit. One reason the joint fails is that nearly all the glue surfaces within the joint contain end grain. Drill a hole, glue in a same-diameter dowel, put it under the stresses of a typical chair and the glue will fail. The tenon works loose.
There is a simple trick to add strength when building the chair: manipulate the moisture difference between the rungs (dry) and posts (wetter). Wood shrinks when it dries. The wet post shrinks, holding the rung ever tighter as it dries. The rung, if dried below the moisture content in the air, will swell once in the chair. Each chairmaker I visited described this technique to me. They used shorthand when describing the process, often simply calling it “green wood.”
The Wood & How it’s Used The chairmakers I visited use local materials, most often oak, hickory, maple, cherry and walnut. Most collect their own logs or work closely with a trusted logger. Extreme discernment is necessary in pursuit of raw material. The quality of the timber directly affects the quality of the chair, and thus the chairmaker’s reputation.
Some chairmakers split out parts, though most work from air-dried milled lumber. Most seek out clear, straight-grained timber. Straight-grained material works easier with hand tools and results in stronger parts. However, a couple chairmakers incorporated winding grain and natural movement into their pieces.
Whether using parts with straight grain or otherwise, every maker follows the grain with their cuts. Following the grain is stronger and allows for thinner parts.
With straight-grained material, repeatability and uniformity are easier to achieve. When splitting out a log, the chairmaker’s goal is to get parts with the grain running the length of the piece. Grain runout, a challenge when using boarded or slabbed material, makes the part weak and requires bulking up pieces for additional strength. It’s for this reason that chairmakers seek clear, straight-grained logs without figure, twist or blemishes. Log yards sell them as “veneer grade.” These logs are the most expensive, yet they yield the most material with the least troubleshooting, waste or compromised parts.
The chairmakers who used the natural grain movement within the log also kept the grain running end-to-end within the piece. The flowing material around knots, natural bends and the swelling at the base of the log all provide opportunity to incorporate natural movement into a chair for an experienced maker.
Good Material is Vital Today’s chairmakers frequently run into sourcing problems. The most common reason given for stopping or slowing down was a change in access (rather, the sudden lack of access) to quality material. Sometimes a trusted local log yard, sawyer or supplier went out of business. The relationship between chairmaker and timber supplier is vital for the rural maker, and one that takes years to develop. Once lost, it takes substantial effort to develop the relationship with another supplier and educate them on the ideal material – especially the sawyer, who can maximize the potential chair parts within a log.
A disruption in access is especially hard for the lathe-based chairmaker, who needs straight-grained planks of consistent quality. Chairmakers who split parts from the log are more adaptable than lathe-based chairmakers who worked from slabbed materials. Disrupt the material to a lathe chairmaker, and it may temporarily shutter the operation. I met a couple idle makers during my travels whose shops were quiet while they sought new suppliers.
The Chairmaking Life & its Future While the construction of the chair is straightforward, the circumstances around being an Appalachian chairmaker are far from it. The chairmakers I encountered needed encouragement to share their successes; they were more comfortable discussing timber quality than themselves. They contributed, some appreciating the recognition while others doing so in spite of it. Yet all of them hoped that their lives might be encouragement for the next generation of chairmakers. Each maker was bullish on the continuation of the tradition and wanted to help see it forward, even if they didn’t know a single other chairmaker still working.
The chair, like its maker, is sturdy yet flexible. It’s lightweight when the parts follow the grain, and durable thanks to the greenwood technique. It’s a chair that’s supported the lives of countless makers and families. It’s deeply rooted within the region, yet it is open to contemporary ideas and the next wave of makers.
Appalachian chairmaking is a dynamic tradition at an important moment in its history. There’s reason for both optimism and concern for its future. All of which made me excited to get on the road and find chairmakers.
A few weeks ago, I wrote about our experience with linseed oil paint. I’ve used it more since, and must update the suggestion to thin it with mineral spirits (low odor or otherwise). I’ve experienced some shiny vs. not-shiny spots on several projects that I think are a result of the thinning…because I’ve not experienced the same when I’ve used the paint as it comes (no matter the brand), without thinning it.
Sometimes we’re able to rub out the sheen differential with a topcoat of soft wax of purified linseed oil. Sometimes, we cannot. I want reliable, repeatable results.
But, I do like the paint to be a little thinner than it comes – so I’m experimenting with some other options. I will, of course, report back. In the meantime, consider the “use mineral spirits” statement retracted.

p.s. I’m not too worried about “fixing” the paint on the chair – that’s easy: apply another coat of paint, this time, without thinning it. After removing any wax residue (and for that…er…use mineral spirits).
We’ve just finished a stick chair class – so I might actually be able to answer your chair questions in today’s Open Wire! (But who am I kidding – I’ll leave those for Chris.) You know the drill (with or without lasers): Leave your woodworking questions in the comments below, and we’ll do our best to answer (note that there may be a lag between your asking and our answering).
To kick things off, here’s a Jeopardy-style answer – I’ll bet you know the question: “Whatever is heavy, cheap and readily available.”
The following is excerpted from “Campaign Furniture,” by Christopher Schwarz.
For almost 200 years, simple and sturdy pieces of campaign furniture were used by people all over the globe, yet this remarkable furniture style is now almost unknown to most woodworkers and furniture designers.
“Campaign Furniture” seeks to restore this style to its proper place by introducing woodworkers to the simple lines, robust joinery and ingenious hardware that characterize campaign pieces. With more than 400 photos and drawings to explain the foundations of the style, the book provides plans for nine pieces of classic campaign furniture, from the classic stackable chests of drawers to folding Roorkee chairs and collapsible bookcases.
Three-legged folding stools appear in many Western cultures, including the French, English and American. They have been popular with soldiers, sportsmen, campers and artists for at least two centuries.
This stool is a great introductory project to campaign furniture, especially if you are new to turning or working with leather. There are only three pieces of wood, four pieces of leather and some metal hardware. You can easily build one in a day.
Choosing Materials I have seen some of these camp stools built using dowels, and they are strong enough to hold most people. However, I like to build them from mahogany, teak or ash that has dead-straight grain. I’ve had nightmares about getting a stick stuck in my backside from a stool disaster.
If you can build the stool with riven stock (oak or ash are good choices), it will be quite strong. Many original stools used 1″-diameter legs. However, my recommendation is to use stouter stock. I have built reproductions with 1″-diameter legs, and they felt too springy under my 185-pound frame.
You don’t need to make the legs baseball bats, but try for something between 1-1/8″ diameter to 1-1/4″ diameter. The leather can be almost anything 7 ounces (just shy of 1/8″ thick) or heavier. Vegetable-tanned leather that you dye yourself is a particularly strong choice.
You also will need rivets to join the leather pieces – unless you are skilled at hand-stitching. While hollow rivets (sometimes called rapid rivets) are inexpensive, easy to find and strong enough, I prefer the look and unerring permanence of solid copper rivets. I used No. 9 rivets with posts that are 1/2″ long.
To attach the leather to the wooden legs, you’ll need three No. 10 x 1-1/2″-long brass screws plus matching finishing washers.
Finally, you’ll need the hardware that allows the legs to open and shut. Traditionally, this was a three-headed bolt that once was easy to find. Now, that hardware is rare in North America. If you are a blacksmith or have access to a good welder, making a three-way bolt is straightforward. I have seen a couple of these bolts for sale in England, but the price with shipping to the United States was more than the cost of the bolt itself.
So I looked for a different way. Luckily, the Internet is good for something other than photos of cats playing keyboards. One maker of custom stools uses some off-the rack hardware to make an effective three-way bolt and shares that information freely on his web site.
Here’s what you need for legs that are up to 1-1/4″ in diameter:
A hex-headed bolt with a 5/16″ shank that is long enough to pass through two of the legs and protrude out the other side by 1/2″. A 3″-long hex-head bolt will work with 1-3/16″-diameter legs.
An eyebolt with a 1/4″ or 5/16″ shank that is long enough to pass through one of the legs and protrude out the other side by 1/4″. (Note: You can hacksaw any of this threaded hardware to length. An eyebolt that has a total length of 2-1/2″ should be sufficient.)
Two acorn-headed nuts.
Three washers.
15 No. 9 copper rivets.
Turn the Legs The three legs are easy to turn, even if your favorite turning tool is #80-grit sandpaper. Turn the legs to round using a roughing gouge or carbide-tipped roughing tool. Create a smooth, clean cylinder of about 1-1/4″ in diameter with a skew or other finishing tool.
The feet shown are 1-3/16″ in diameter and 5/8″ tall. Make the feet by turning down the foot. Then turn the ankle to 7/8″ in diameter. Round the foot, then taper the rest of the leg down to the ankle. The taper should begin 6″ from the bottom of the leg.
I added four small grooves where the hardware holes will go – two above the hardware and two below. Little details such as these grooves and beads make the legs look like something fancier than three store-bought dowels.
Sand the legs to remove any rough tool marks. I finished the legs on the lathe. First I burnished the surface with a “polissoir” (a French polishing tool made from tightly bound broom corn). Then I applied beeswax to the legs with the workpiece spinning. I used the polissoir to drive the beeswax into the pores of the wood (again, while the lathe was spinning). Then I used a rough cotton cloth (I’d like to be fancy and say it was muslin, but it was an old bag that held corn grits) to buff the wax. Then I applied another coat of wax and buffed that.
If you want to add a little age to the wood, apply a coat of black wax and push it into the grooves and pores. Let the wax set up then buff it.
Wax is not a permanent finish, but it is easily renewed or repaired if your stool is for the drawing room instead of the campsite.
Bore Three Holes All three holes are located in the same spot on each of the three legs and should be the same diameter – just big enough to allow the hardware to pass through. The holes are located 11-5/8″ down from the top of the legs.
The best way to bore these holes is with a drill press or hand-powered post drill. You want the hole to be dead straight and pass through the middle of the leg. If you are a whiz with a hand drill or cordless drill then go for it.
Install the Hardware Strip the hardware of its zinc if you like – I use a citric acid solution for this. Here’s how the hardware goes together:
Put a washer on the bolt. Push the bolt through one leg.
Place the eyebolt on the post of the bolt. Put the other leg on the bolt. Add a washer to the end of the bolt, then drive on the acorn nut.
Push the post of the eyebolt through the third leg. Add a washer and acorn nut.
Drill pilot holes that are deep enough to receive the No. 10 screws into the top ends of the legs.
Leather Seat The seat is four pieces of material: a triangular seat and three pockets that look a bit like lips when you cut them out. When I cut out leather, I make patterns for my pieces from thin MDF or hardboard – usually 1/4″-thick material.
Put the patterns on the leather and cut out the seat and three lips using a sharp utility knife. You can hand-stitch the lips to the seat. If you aren’t up for stitching, rivets work well and give the project a military flair.
Secure each lip to the seat first with one rivet at one of the tips of the seat. Punch a snug hole for the rivet through both pieces of leather, drive on the washer or “burr,” snip off the excess and peen the post over the burr.
Now bend one end of the lip up and rivet the end to the seat about 1/4″ from the end of the lip. Repeat for the other end of the lip. Finally, add two more rivets between the three existing rivets. Repeat the whole process for the other two corners.
One quick note on neatness: Be sure to put the burr so it faces the floor for all these joints. After the pockets are riveted, use a sharp utility knife to trim any little bits of the pocket that aren’t flush to the seat.
If you purchased undyed leather, finish the leather with a dye, oil and wax. Burnish the edges with a piece of wood and a little spit (water will do nicely as well).
Attach the seat to the legs. Punch a clearance hole through each lip that will allow a No. 10 screw to pass. Screw the leather to the legs with a finishing washer under the head of each screw.
That’s all there is to it. You can make the tool easy to transport by making a belt that will go around the girth of the closed stool and screwing that belt to one leg. Or you could make a canvas bag embroidered with your football team’s logo. After all, when going into battle, it’s always best to fly your colors.
Make a Three-way Bolt
As I was finishing work on this book, woodworker Mike Siemsen sent me a clever three-way bolt he had made from off-the-rack hardware. According to Siemsen, here’s how to make it. Hardware needed:
A 1/2″-13 heavy hex nut. (Regular nuts will not work well; get low carbon, not hardened.)
Three 5/16″-18 x 2-1/4″ bolts (machine screws, get low carbon, not hardened.)
One 5/16″-18 nut (for cutting off the bolts to length).
Three 5/16″ washers.
You will also need a 5/16″-18 tap, a drill for the pilot hole (F-size bit which is .257″; 1/4″ will probably work) and a drill press.
Center punch the center of every other face on the 1/2″ heavy hex nut, put it in a drill press vise and bore the pilot holes for the tap. You can then either run the tap by hand or put the tap in the drill press and turn it by hand, no power! Keep things square to the face being drilled.
Next take the three 5/16″ bolts, screw the nut on them all the way up to the unthreaded portion and saw off the excess end. Remove the nut and file or grind the burr off. It is important that the unthreaded portion be around 1-1/4″ long.
You can blacken the hardware, or remove the hardware’s zinc coating using a citric acid solution and let it patinate naturally. The hole in the 1/2″ nut is a nice place to add a wooden cap or a small turned finial.
