One of the (many) barriers to making staked furniture or chairs is wrapping your head around the compound-angle geometry. And then figuring out how to execute it at the bench.
The new Crucible Chairpanzee ($16 plus shipping) does the trigonometry for you, allowing you to translate rake and splay into sightlines (which create your layout lines) and resultant angles (which is the setting of your sliding bevel).
This allows you to easily design new pieces of furniture with compound angles and to replicate angles from existing pieces of furniture from photos.
The Chairpanzee is a clever sliding calculator that is printed and assembled in the United States. Here’s how we use the Chairpanzee on a chair design (though it can be used for tables, stools or any other piece of staked furniture).
To calculate the “sightline:”
1. On the underside of the seat, draw a line connecting the two front leg mortises (as shown above). This is the baseline.
2. Move the calculator’s slider to the desired splay angle in the top window.
3. Next to the lower window, select the desired rake angle. The number shown in the adjacent window is the sightline angle.
4. Draw the sightline angle on the underside of the seat using a protractor. The 0° on the protractor should be directly on your baseline.
5. Repeat steps 1 through 4 for the rear legs.
To calculate the “resultant:”
6. Confirm that the calculator’s slider is set to the desired splay angle in the top window.
7. Next to the lower window, select the desired rake angle. The number shown in the adjacent window is the resultant angle.
8. Set your sliding bevel tool to the resultant angle and place it directly on the sightline on the underside of the seat.
9. Drill your mortise. Keep the drill bit perfectly parallel to the blade of the sliding bevel.
The Chairpanzee is available for immediate shipment. We hope that some of our retailers will also carry this product for our international customers.
In the coming week I’ll post a video that shows how it’s used.
“Make a Joint Stool from a Tree” was a first on several fronts for Lost Art Press. It was the first book in full color, the first to use a larger format and the first to have a dust jacket.
It was also the first “edition” book Chris designed, with the guidance of Wesley Tanner (who would later design the award-winning Roubo books for Lost Art Press). That’s who introduced Chris to the venerable book designer’s bible: “Methods of Book Design,” by Hugh Williamson (1956).
It took so long…they were working on it for more than 15 years (most of that prior to signing on with Lost Art Press). A fun drinking game: Every time Peter’s outfit has changed in the pictures, take a shot. (On second thought, that’s not such a good idea…). You can also watch Peter and JA age and change throughout the pages.
Fig. 7.2 Clockwise from the left, these pigments are: bone black, iron oxide and yellow ochre. A little goes a long way, especially with the red. Store them in a dry place and they’ll last a long time.
Now that the stool is all assembled and trimmed, it’s time to apply a finish. At this stage, you can use your favorite finish, but if you would like to explore period-style work further, then oil-based paint is an excellent choice for a period finish. This is attainable, but with some cautions.
Surviving artifacts sometimes have remnants of their original painted finish, and these can be analyzed and the pigments and vehicles identified.
This analysis is rarely applied to “clear” finishes; it usually centers on surviving colors appearing on period works. We have benefited from colleagues who have shared with us the findings of their studies, but there is still a long way to go in this aspect of 17th-century furniture studies.
Fig. 7.3 Another ingredient in period paints was calcium carbonate. It was used as a filler to extend the paints’ covering abilities. A good easy source for small quantities is blackboard chalk. Break it up with a hammer into the smallest bits you can, then mix it in with your pigments.
Paint consists mainly of a color, the pigment, that is dissolved in a medium. In many cases the medium is a plant or nut oil, such as linseed oil (from the flax plant) or walnut oil. It is often thinned with turpentine. One aspect of period paints that is best avoided today is the use of lead as an ingredient. The lead served to dry the oil, and in its stead you can add just a few drops of Japan drier, which will help the linseed oil dry a little more quickly. A little umber pigment mixed in with your other colors will also help with drying; usually it’s too small of an amount to affect the color much.
Fig. 7.4 There’s no way around it – paint-making is messy. A dropcloth on the bench is a good idea. If you have a small piece of glass such as this one, you can scrape your mixed paint into a shallow dish as you go, them mix more to add to it.
For our stools, we paint them with homemade paints made by grinding dry mineral pigments in oil, or an oil/varnish combination. The available colors are usually earth colors – reds, yellows, browns – and carbon pigments – lampblack or bone black. Artists’ supply outfits are a good source for dry pigments. Use their linseed oil also; it is better quality than the boiled linseed oil from the hardware store.
Red is the standard color based on what little evidence we have seen from studying period pieces. We use iron oxide pigment. It goes by various names: iron oxide, Indian red, Venetian red or red ochre. The best tools for mixing the paint are a muller and a piece of plate glass. The muller is essentially a flat-bottomed pestle made of glass. Like many good tools, they are expensive. You might try your first batches of paint by grinding with a mortar and pestle, or even just a palette knife on glass. Then if you plan on going further, you’ll want the muller and glass.
Fig. 7.5 If you decide that mixing paint is for you, then eventually you’ll want a muller such as this. A mortar and pestle works, but it’s harder to get paint out of a mortar than off a flat piece of glass.
Make a ring of pigment, and pour in some of the medium. Slowly mix the medium and pigment together with a palette knife, then take the muller and work in a circular motion to dissolve the pigment in the medium. Mix up enough to paint your whole stool; you don’t want to stop during the painting to mix up more paint.
Use a clean, soft, natural-bristle brush to paint the stool. Period brushes were round; the most common modern ones are flat. If you want to try round ones, get them from an art supply store rather than a hardware store. Thin paint will have a better chance at drying than thicker, more opaque paints. Several coats will result in a more solid color and finish. You can combine the red and black in a contrasting application, using the black for the mouldings, or even pick out aspects of the turned decoration in alternating red and black.
Warning: Linseed oil generates heat as it dries. This can cause spontaneous combustion of rags and brushes and any other absorbent materials that have come in contact with the oil. After use, put all such materials outside to dry in a well-ventilated place for at least 24 hours in a temperature of not less than 40° Fahrenheit. Or you can thoroughly wash all contacted materials with water and detergent and rinse.
Fig. 7.6 Iron oxide reds can vary from place to place. Some are brick-red, some are brighter. You can also mix pigments together, add some yellow ochre to iron oxide to add some variety to your colors. Vermillion is a very bright red, so use it as an accent color.
Recent research at Winterthur Museum and the Museum of Fine Arts, Boston, has identified examples of 17th-century paint made with pigments mixed in thin solutions of hide glue instead of oil. To do this yourself, prepare the glue granules just as you would for using adhesive, but with more water. Fill the bottom of a glass jar with the glue granules, add enough water to cover them plus a little more, and let it soak overnight. When you’re ready to make paint, heat the glue mixture slowly. If you don’t have a dedicated glue pot, you can put the glue in a glass jar sitting in a few inches of water in a pot. Stir regularly. Keep the mixture thin. When the glue is nice and thin, turn off the heat, and you’re ready to mix the paint.
Just as with the oil, start by sifting some pigment onto your plate glass, or in a mortar. Then pour some glue in and start mixing them. Keep adjusting by adding pigment and glue until you reach the solution you’re after. Painting a whole stool with this paint is tricky; the glue thickens as it cools. It requires a little tinkering, so add water if it thickens, and return the glue to the heat from time to time as well. This protein paint needs a finish over it, or it can rub off. The research indicates a plant-resin varnish as a top coat.
One of the many “COVID chairs” I’ve built during the last seven months.
With woodworking schools opening across the country, we are asked almost every day when we will resume classes here. Here’s the deal.
We plan to wait until there is a safe vaccine for COVID-19. There are several reasons for that decision.
Classes here can be physically strenuous because of the handwork. Students sweat, huff and puff a lot as they saw, plane and chop. Doing that work with a mask is misery, and the heavy breathing is ideal for spreading the virus.
Our workshop is compact. Keeping people at a safe distance is difficult, even with small classes.
Our students come from all over the world. Some of our students are older and therefore more vulnerable to the virus.
My mother and Lucy’s mom (both local) are both particularly vulnerable to the virus, and we see them several times a week.
If anyone got sick (or worse) at one of our classes, Megan Fitzpatrick and I would never forgive ourselves.
As soon as a vaccine is readily available, we will open our doors for classes and a long-overdue open day. If you want to be among the first people informed about classes, the best way is to subscribe to our blog. Simply enter your email in the box near the top right of this page by the headline: “Subscribe to the blog via email.” You won’t get spam. We don’t sell people’s addresses or have sponsors/advertisers. You’ll just get an email every time there is a new entry.
We look forward to having some new faces around here. I know Megan must be sick of me and my prattling on about chair design and marsupial trivia.
Until then, stay safe and we hope to see you soon.
Editor’s Note: Apologies if you received this post twice. We had some technical problems with this entry (our fault and not Nancy’s).
In her profile on the Brigham and Women’s residency alumni web page, Dr. Ouida Vincent had some fun with the pro forma question “DO YOU HAVE A FAVORITE MEMORY FROM RESIDENCY?”
“Spending the night out with co-residents at the ’70s disco,” she answered, punctuating her response with a single word: “Polyester.”
This disarming response will come as no surprise to those who know Ouida, whether in person or from Instagram, where her warmth, humor and sense of adventure are on regular display. “Headed to Handworks by way of MSP,” she wrote in May 2017. “Please say hello… I’ll be the BWWDL” – as she’d previously described herself, the “BLACK WOMAN WITH DREAD LOCKS” – because (let’s be real) how many Black women (or men) with dreads would you typically expect see at a gathering of hand-tool woodworkers in rural Iowa?
With her Dutch tool chest in her shop.
When we spoke, on a crisp Saturday morning this fall, she’d just returned from delivering sourdough cinnamon rolls to her mother. It was a short walk up the hill by her house; she was still in her pajamas, under a Carhartt jacket.
Along with thousands of others, Ouida (pronounced WEE-da) took up sourdough bread baking in April, when the pandemic prompted so many to plunge themselves into baking that stores could not keep yeast on the shelves. It wasn’t her first experience with baking; at Cornell she did a medical school rotation on the Navajo Reservation in 1989, staying with a family who baked wholewheat bread or cookies every day. Inspired by their example, she took up baking herself when she returned to med school. Although her first few loaves were “like hubcaps,” she kept at it and quickly improved. She baked every weekend until her professional work became too demanding.
Ouida approaches sourdough baking with the analytical rigor of a scientist and the enthusiasm of one who bakes for love, not money. Her Instagram feed is full of boules and batards – some whole, some sliced in half to reveal herbs, olives or “crumb.” An early September entry that shows the kind of springy texture I can only dream of producing reads like notes on an undergraduate’s experiment:
“[W]hen I want to check oven spring, I look at how the holes are oriented and if the entire loaf from bottom to top was involved in ‘spring.’ You can get three patterns[:] no spring (dense loaf) that may or may not have risen any, spring primarily on the outside of the loaf with a dense (yet hopefully done) interior and spring that involves the whole loaf. The holes will be elongated in the direction of spring and will glisten.”
Note the measurements. Clearly the work of a scientist.
She brings the same studious curiosity to woodworking. Ouida sees a piece of furniture she likes and figures out how to build it. Her office and home are furnished with pieces of her own making. And when she decided a proofing box would be a boon to her sourdough baking, she puzzled out what it would take to fabricate one.
Ouida’s proofing box with a loaf in progress.
These days, Ouida, whose day job is clinical director of a hospital on the Navajo Reservation, is “in a mask 10 hours a day, five days a week.” Anyone who pays attention to national events will be aware that Native Americans have been affected terribly by Covid-19. Ouida adds, “Even when there is a vaccine, I will wear my mask (even after getting the vaccine). This is about public health.”
Ouida was born in Nashville, Tenn., the fourth of five children. When her mother and father married, her father brought three from a previous marriage and her mother brought her; they had one son together. Her name is common in the South. “My mother told me that she heard the name and wanted me to be remembered, so she gave me the name.” Then comes the zinger: “You can imagine what kids and substitute teachers did with [it].”
Ouida and her little brother.
She can’t remember a time when she wasn’t fascinated by making things and figuring out how to fix them. Her older brother David was “a real Mr. Fix It” from the start, Ouida says; she followed him around and learned from his example.
After her parents split when Ouida was 10, her mother moved Ouida and her younger brother from one place to another, wherever she could find work, usually in college financial aid offices. Ouida would have signed up for shop class in school, but as a girl born in 1963 she wasn’t allowed to. That changed when her family moved to Virginia Beach, Va., in 1976; she enrolled in shop class and small engine repair. She and her classmates learned to strip down and rebuild two-stroke and four-stroke engines, restoring them to working order; they also had to frame the corner of a house, complete with functioning plumbing and electrical service.
When they moved to Alabama in 1979, Ouida found herself barred from shop class once again. Undeterred, she decided to go ahead and build things on her own, though she found that was more easily said than done, with few tools and no shop. While working on a body for an electric guitar she asked the shop teacher at school if she could use the band saw. He asked her to prove she knew how – a challenge she met in short order. He gave her permission to use the shop facilities when classes weren’t in session. She’s been building ever since.
Given her facility for learning new skills and diagnosing problems, it’s not terribly surprising that Ouida, who excelled academically, found her way into medicine. She graduated from Cornell Medical College in 1990 at the age of 27, then did a residency at Brigham and Women’s in Boston. “My uncle was an Ob/Gyn. It was really the first medical career I was exposed to. I was briefly attracted to general surgery, but the general surgeons I was exposed to seemed not to have personal lives. I was ultimately attracted to the combination of surgery and diagnostic medicine that obstetrics and gynecology offers.”
She originally hoped to do a medical student rotation in Alaska, but when she inquired, she learned that all rotations there were filled – she would have had to apply at least a year in advance, rather than a few months ahead of the starting date. “When I walked in to talk with one of our deans, she was opening a letter from alumni who had taken jobs in Shiprock, N.M. They had space for students, so I went. The year was 1989. I fell in love with the medical community and knew I wanted to return,” though she adds “I didn’t plan on making a career out of it.”
In 1998 she moved to Gallup, N.M., and became Chief of Obstetrics and Gynecology. When her real estate agent heard about her interest in woodworking, she mentioned there were classes at the local branch of the University of New Mexico. Ouida signed up for a course in cabinetmaking. The college had a well-equipped machine shop, but no hand tools. As she deepened her experience of working with machines, she learned another valuable lesson – “the frustration of power tools!” Even though the college had a full-time staff person charged with repair and maintenance, “there was always a machine down.”
Ouida’s work responsibilities grew, leaving her with less time for classes, yet she continued to pack in as much woodworking as she could. One of her early projects was an 8’-high x 3’-wide media cabinet. Another was a hutch based on an article in Fine Woodworking; it’s in her office today.
In 2006 she bought a property in Colorado, attracted in part by a dilapidated barn on the site. “This is my woodshop,” she remembers thinking when she first saw it. Termites and rain had done their worst; contractors she called for estimates to rehabilitate the structure said it wasn’t worth saving, that she should build something new. “But I wanted to work in a barn,” she says. Eventually she found a contractor who was willing to fix it up for her.
The barn shop at dusk.
Ouida slowly taught herself to use hand tools. She learned a lot from Chris Schwarz’s videos on hand tool basics and watched the Popular Woodworking series “I Can Do That.” She made a desk of ambrosia maple and cherry for a friend; the hand-cut dovetails were “so gappy that I made the gaps the same size and backfilled them with filler of a different color.” She persevered and improved. The same went for sharpening. “The first time I sharpened a plane blade it took six hours,” she says. But she found the more she worked in hardwoods, the greater her appreciation of the need for sharpening and the better at it she became. In the end, she says, “the wood became my best teacher.”
Around 2011 she made some shop stools based on a video by Mike Siemsen. When “The Anarchist’s Design Book” was published, she built one project after another from it – a boarded bookcase, staked desk (now in her office), six-board chest and staked chair. “I would have made more from that book,” she says, “had Peter Follansbee not published his book and completely derailed my life! I’ve literally done nothing but carve since 2019.”
Evidence of obsession.
Ouida is well aware of the sacrifices her mother made as a single parent. She also deeply appreciates her maternal grandmother’s support, calling her “a constant figure in my life until she passed away in 2001.” She cites one incident in particular, which culminated in the United States Supreme Court case NAACP v. Claiborne Hardware, to illustrate the impression her grandmother Dolly made.
Dolly Thompson was from Mississippi and had a ninth-grade education. “It was in the Jim Crow South,” Ouida points out by way of context. Even though the population of Claiborne County, where they lived, was majority Black, all the political seats were held by White people. Her grandparents owned a funeral home and were solidly middle-class. But when they traveled cross-country to attend mortuary conventions, they always had to think about where they’d be allowed to stay at night.
It was common in that time and place for Black people to be called names (if their presence was even acknowledged) and forbidden to use public restrooms or sit at lunch counters. Tired of being treated as second-class citizens when they were upstanding members of the community, Ouida’s grandmother (her grandfather died in 1962) and many of her fellow community members, working with a local chapter of the National Association for the Advancement of Colored People (NAACP), decided to “talk with their dollars.” They organized a boycott of White-owned businesses, setting up a supply house of their own called Our Mart to keep fellow citizens supplied with hardware, food, clothes and other everyday needs. They funded the project by selling shares.
Ouida’s maternal grandmother, Dolly Thompson.
Several of the White-owned businesses joined forces and sued for damages – in a majority-Black county, their businesses couldn’t survive without the now-missing income. When the Mississippi Supreme Court ruled in the White businesses’ favor, Ouida’s grandmother and her fellow boycotters took the case all the way to the United States Supreme Court, which ruled in favor of the NAACP.
The whole thing, she notes, came about “simply because that group of people wanted better treatment.” Although this was her grandparents’ experience, Ouida understands it’s not that far removed from our own time — she belongs to the first generation to grow up outside of Jim Crow. And it’s easy to see how Ouida, with these determined and hardworking role models, became the kind of woodworker who doesn’t flinch at challenges, but sticks at a task until she has mastered it, having lots of fun along the way.
Summing up our conversation, she reflects that “the reason I’ve continued doing [woodworking] is the stimulation it provides.” She trained as a surgeon, but her work for the past several years has been in administration. She misses the contact with tools and materials. Bread making helps fill the gap; woodworking goes even further. “Now I get to hold instruments in my hand that use fine motor skills., similar to using a scalpel,” she adds. No wonder she can’t stop carving.
One of my biggest struggles so far with “The Stick Chair Book” is that I can’t build a chair the same way twice.
When I start to build a chair, I have plans and patterns. But it takes 5 minutes for those plans to get pushed aside. I pick up a stick for the stretchers and note the arrow-straight grain. Thanks to that, the stretchers don’t have to be a full 1-3/8” square; I can go smaller. The wood for the arm, however, is some fast-growth stuff and feels a little weak. I should beef up its thickness.
It goes from there. I get an idea for how to make the gutter between the saddled seat and spindle deck crisper. Yeah, I’m going to do that on this chair. The person who will get this chair has a round back, and he likes to lean back in chairs – hard. I’ve watched him do it. This chair needs an extra medial stretcher. And I’m going to pitch the back sticks an extra 5° backward to discourage him from tipping back on the chair’s back legs.
Soon, the chair looks nothing like my drawing. But it’s the right chair.
So how do I explain this process to the readers of the book? My plan is to present the chair plans as drawn for an average-size person with a mid-range BMI (body-mass index) and typical popliteal height. Basically, someone who doesn’t exist outside a Pringles’ consumer group study in Ames, Iowa.
And then say: OK, now you (the builder) need to think about the sitter. Are they short? Lower the seat height to avoid cutting off the bloodstream in their legs. Do they have a tall back? You need to increase the length of the back sticks to cradle the shoulders. Do they have long arms? Consider lowering the arm height by 1/2” or so. Do they have a massive hinder? Add stretchers. Wedge them. Widen the seat.
And on and on.
Also, do what I do. Build your first chairs using cheap wood – poplar and red oak in my case. Poplar for the seat and arms; oak for the other parts. Build them without fussing. Hell, don’t even saddle the seat. It might cost you a day of work and $30 in wood. But it will give you $1,000 worth of answers. Especially when you (and the person it is intended for) sits in it.
Then cut the stupid thing up and use the parts for stools. Funny, I’ve built a lot of stools.
