Though I am done writing books on workbenches (scout’s honor), I am always on the lookout for interesting historical examples and clever features that I can use in the future.
This week I spotted one that was particularly interesting. I’m calling it the “Baby Deadman,” which is the most horrible name I have ever given anything in this world (including the time I tried to name a cat “Kilgore Trout”).
The bench shown above is featured in “The Cabinetmaker’s Art in Ontario: Circa 1850-1900” by Lilly A. Koltun, published in 1979 by the National Museums of Canada. Researcher Suzanne Ellison recently dug it up using her superpowers. Download the pdf here.
The paper is a biography and shop inventory of Francis Jones of Middlesex County, who made furniture (and dealt in farm implements and undertaking) during the second half of the 19th century.
The section on the workbench notes that its top is 21-1/2” x 78” and the bench is 34-1/2” high. Unusually, the bench has a tail vise, but it doesn’t appear to have a series of dog holes on the top. It does have a metal planing stop (barely visible) which is mentioned in the inventory. And a nice holdfast.
I was struck by the two sliding board jacks (sometimes called a “deadman”). The large one is typical. But the small one on top is unusual and ingenious. Here’s why: I built my first board jack in about 2001, and it’s great for holding large panels and residential doors on edge. But most of my work doesn’t need the full capacity of the jack. Mostly, I just want a movable peg that will help support boards as I edge-joint them.
This bench gives you both.
In fact, I might consider adding only the smaller Baby Board Jack (now THAT’s a better name) to one of our existing benches to fool around with it.
This chair is the third (and final) in a series of old-school stick chairs built with a batch of local black cherry. This particular example is inspired by one of my favorite 18th-century Welsh stick chairs, which features thin back sticks that splay out to meet a thin comb.
The “Family Tree of Chairs” letterpress poster is now available in green ink. (It is also available in black at the same link – so make sure you select the color you want before adding it to your cart.) There are 200 numbered copies of these 16” x 20” posters, printed on a thick, textured 100-percent cotton paper.
When I think about the things I would grab from my shop during a fire, my chair patterns would be at the top of the list. The patterns I own have evolved during the last 18 years and began with some tracings I made during my first chair class.
These patterns are still my jumping-off point for all my existing and new chair designs.
In order to help readers of “The Stick Chair Book” begin their own collection of patterns, we’ve made five sheets of full-size patterns for all the major components in the five chairs in “The Stick Chair Book.” NOTE: If you have bought the Early Adopter Digital Package for this book, you already have these patterns in your possession. No need to buy them twice or thrice.
We are selling the patterns two ways.
For $20 plus shipping, you will receive five 22” x 34” sheets printed on lightweight paper used for architectural drawings. These can be easily cut out and stuck to thin plywood to make templates. The patterns include mortise locations for the legs and sticks. And the sightlines for drilling the leg mortises.
For $10 you can download a pdf of the five sheets, which you can get printed out at your local copy shop, reprographics firm or office supply store.
A couple other updates: We have restocked on Crucible Type 2 Dividers and have another big load on the way to the warehouse.
Also, we were hoping to launch our Lost Art Press beer steins this week, but we hit a snag. We didn’t receive our full shipment of them. So we decided to hold off on launching them until we had our entire order. Stay tuned.
The above phrase could easily be the punchline to a Norwegian joke about our neighbours in the east. Here in Norway it’s a cultural staple to tell jokes about the Swedes. Unfortunately, this also says a lot about our own inferiority complex in our relationship to them. And I’ll be the first to admit it: We’re not as cool as they are. While we all agree that they talk weird, eat horrendous food (like rotten herring) and that IKEA is just an evil plot against the world. But they’re actually annoyingly successful at almost everything.
The Swedes are both great innovators and traditionalists. They even successfully export a lot of their ideas to the rest of the world. Among others, they’ve given us Abba, Wille Sundquist, Volvo, Bluetooth and Spotify. And even dynamite! Oh, and they designed the classic Coca-Cola bottle! And us Norwegians? Well, we’re famous for killing whales, raiding and pillaging villages around the world, skiing and brown cheese. How about that!
Therefore it’s no surprise that they also did some groundbreaking scientific research on chair design. Surprisingly, I’d had never heard about this. Which is a bit weird, considering I’m a nerdy chairmaker myself and live just next door to them. Instead, it all came to me when I excavated a dusty Åkerblom Chair from a Norwegian barn earlier this summer. When I started reading about the chair, I learned it was an interesting part of chairmaking history that has been long forgotten and perhaps little known outside our Scandinavian borders.

The Chair Doctor
The story starts with Bengt Åkerblom (1901-1990), a Swedish doctor who became a pioneer in the field of electromyography. This is simply put a method of studying and evaluating the muscular strain induced by different body positions and movements. It is done by measuring the electrical nerve activity in skeletal muscles. Dr. Åkerblom had a special interest in sitting postures. Through his studies, he pretty much laid the foundation for the science of modern ergonomics. In 1949 he released his 187-page long thesis called “Standing and Sitting Posture with Special Reference to the Construction of Chairs.” It was also sold as a hardcover book.

Bengt Åkerblom’s goal was to scientifically prove that a chair could be designed to minimize muscular strain and discomfort. In other words: to become the most comfortablechair possible. The main findings of the study were:
The position and shape of the backrest, which is applied to the weakest part of the spine
The importance of the height of the chair seat from the floor
The slope (also called the tilt) of the seat
The seat must allow for the sitter to move around and change between positions
He came to his conclusions through both lab experiments and observational studies of people using chairs in daily routines and work life. He found that chairs formed to mimic the human body usually gave no or too-little support to the lumbar spine. In other cases, the supporting area of the chair back was too high up. Åkerblom also proved that the seat would have to tilt the sitter backwards in order for the back rest to function properly. He also found that a chair seat that was too high above the floor would induce pressure on the underside of the sitter’s thighs. This would impair blood flow to the legs and result in fatigue and discomfort. Lastly, a pommel-less seat with only a shallow saddling to it would let the sitter easily shift position, which increases the sitter’s comfort over time.
It Takes Two to Tango
In 1931, another Swede, Gunnar Eklöf from Stockholm, graduated as an interior architect. After working for a lamp factory and some furniture makers for a few years, he was offered a job as a furniture and interior designer at Karolinska University Hospital in 1936. This is where his life took a turn.
During his work at the hospital he developed an interest in ergonomics. Although I have not been able to find out how, he must have met Dr. Åkerblom during this time. Immediately after the war, Åkerblom was finishing his thesis at the Karolinska University Hospital and was probably keen to try out his theories in real life. However he was a scientist, not a chairmaker. One can only imagine it must have been love at first sight between Åkerblom and Eklöf.
And so Gunnar Eklöf designed a simple stick chair based on Åkerblom’s findings. As you can see from the protoype drawing below, all of the main principles have been incorporated: The low seat (15-3/4″ above the floor), the 6° seat slope and the star of the show – the bent back sticks providing lumbar support at 6-1/2″ above the seat. The seat is almost flat and has a very subtle saddling, allowing the sitter to easily shift her weight.
Bringing it to the Masses
Neither Åkerblom or Eklöf were chairmakers. They needed help to bring the chair into life and about 1950 they contacted the Nässjö Chair Factory to manufacture the conceptual chair. The Åkerblom Chair required exact engineering, including steam-bending. At this time, the Nässjö Chair Factory was already one of the largest chair factories in the Nordic countries. Nässjö had started producing stick chairs and rocking chairs in 1870, so by the time they were contacted by the two young designers, they already had 80 years of experience under their belt.
The Nässjö Chair Factory photographed in 1932A chairmaker at work at the chair factory, working beside a mountain of chair seats. The photo was taken about 1950-1960.
During the years 1949 to 1958, more than 120,000 Åkerblom Chairs were produced and sold. All were made from solid Swedish birch and had the same conceptual features. Gunnar Eklöf designed several variants of the chair, including side chairs, dining chairs and arm chairs. The most popular model was the “SZ03,” a light and elegant armless stick chair that had all of Åkerblom’s ergonomics baked into the design.

The one I found in the barn however, was the Åkerblom Karmstolen – the armchair version of The Åkerblom Chair. It features a so-called “captured arm,” where the outer back sticks are mortised through the back part of the armrests. This is a common arm joint, but it is most common in old Irish stick chairs. The armchair is made from both solid and laminated birch. The seat is glued up from several pieces of solid wood. All of The Åkerblom Chairs had a maker’s mark under the seat to prove their authenticity.

So, How Does it Sit?
I’m pretty sure Dr. Åkerblom meant for his sitters to be upright and working at a desk. I’m not a desk guy, and I usually sit like a sack of potatoes. So I figured I’d put the chair to a test and sit like an office worker. And let me tell ya, it was dang comfortable. I almost felt like having a Swedish meatball and humming “Dancing Queen.” And for a Norwegian, that ain’t bad!
