Tage Frid — The Great Dane

Woodworking is a lifelong journey of discovery and rediscovery. Along the way you’ll meet a lot of great folks and interesting characters who are surprisingly willing to share advice and help you out. The craft has been passed down this way for millenia.

Everything Old is New Again

Modern woodworking media seems to go in cycles much like clothing styles or car designs. Right now it’s popular to study the early works of Moxon, Roubo and Nicholson etc., or prove you have the best router or table saw trick. Others are interested in espousing the mix of old and new tools and techniques which is not a new concept. Manual training programs like those at NBSS have been doing it for over 125 years and the Shakers before them etc.

I want to buck the current trend and take a trip back to the 20th century. When I got started in traditional woodworking one of the first teachers I had was Tage Frid via the  ‘Tage Frid Teaches Woodworking’ 3 volume set with its iconic white covers. I haven’t seen these books or Tage’s work come up much lately and thought it would be helpful to blow the dust off those books hopefully re-kindle some interest as I think they are a great resource.

Tage Frid

Tage (Pronounced ‘Tay’) taught me and countless other woodworkers the basics via his books and teaching.  He grew up in Denmark and apprenticed as a cabinetmaker. His time as a journeyman took him to various other shops including the Royal Danish Cabinetmakers. In 1948, at the age of 33, the American Craft Council persuaded him to immigrate to New York and teach woodworking. Tage lead the woodworking program at the School for American Craftsman in Alfred NY which was later moved to the Rochester Institute for Technology. From 1962-1985 Tage was a professor of Woodworking and Furniture Design at RISD helping to propel that program to national prominence.

Also notable was Tage’s involvement with Fine Woodworking where he worked as an editor from it’s inception in 1975, through 171 issues until his passing in 2004. Described as having a sharp tongue and an ‘impish’ smile you can get a small taste it it through his writing and interviews which often have some memorable nuggets.

He could cut a dovetail while joking and flirting with the ladies. He referred to nails in furniture as ‘Swedish dowels.’ When critiquing a piece of work, which was nerve-wracking for students, the blow was slightly blunted by his sarcastic humor.  Hank Gilpin recounts some memorable zingers:

“Oh, good curve. Too bad it’s the wrong one”
“Nice dovetails. What’d you use — a chainsaw?”
“Beautiful legs Henry. What were you thinking about — an elephant?”
And the classic: “Congratulations, you’ve just figured out the most complicated way to hold a board 30 inches off the floor.” [*]

The goal was not to put anyone down, it was to help each student stay humble and push him or herself to reach new heights in a fatherly kind of way. I had a similar experience during my own training and find myself rehashing some Frid one liners and Rich Friberg-isms in my own shop and classroom. Thankfully the flavor of sarcasm I learned from Rich is a little less harsh, but still fun.

Teaching

When asked about teaching repetitive topics Frid had the following to say:

Don’t you get bored demonstrating the same old dovetail?
“Maybe you left too early. I always demonstrate difficult joints and techniques depending on what the audience wants. The dovetail is just the overture. What I like about teaching is that I learn something new every day. A student asks me, ‘Why can’t I do it this way?’ and I think, ‘Why not?’ Then we figure it out.” — Tage Frid (excepted from an old interview in Fine Woodworking you can read here.)

Levity aside, Frid’s teachings focused on teaching solid joinery — form should follow function, wood has a beautify of its own that should be enhanced and not hidden and instilling an innate sense if proportion via a keen eye for detail.

“The best tool is the eye. Train the eye. The eye guides your hands to achieve the form. If the eye says ‘It’s right’, it is right” — Tage Frid [*]

With a solid grounding in the basics and exposure to a wide range of tools and techniques students are able to take on whatever challenge a project or shop can throw at them. During his lengthy career as a teacher, writer, editor and studio craftsman Frid helped teach several generations of woodworkers. You can see his work live on through his students and their students.

Design

Working in the Danish-modern style a lot of Frid’s pieces had a distinctive look compared to many of his American contemporaries. They were generally lighter looking with delicate lines and curves that celebrated the grain. The designs are especially interesting when you view them in the context of the time they were produced — the 1940s-1980s.  Many of them were years ahead of what we think of as the the mainstream designs of the time .

For me, one of his most iconic pieces is the now famous 3 legged stool. If you read his 3rd book you’ll learn about how he came up with the design while watching a horse show and sitting on a fence. It was an interesting case study as he explains some of the revisions he went through to hone the design. These stools have been on my mental to-do list for about a decade now and I hope to eventually build some for myself.

When he first arrived in the US in the 1940s there were no good places to get a solid workbench. As a result Frid had to design and build a bench for himself and for his classrooms.  Based on a traditional continental design with a shoulder vise and a tail vise the bench below was well suited for a cabinet maker. Over the years many a student, both in person and via his writing, would build and use one of these benches or a similar variant.  In some upcoming posts you’ll see me build a scaled up version for my own shop.

What’s with the book report on Tage Frid?

Tage Frid’s work has shaped several aspects of my woodworking, design and teaching and I had a laundry list of odds and ends I wanted to share with you here. I also have been working to finish off my Tage Frid inspired bench and wanted to set the stage for it.  And lastly because once I saw it, I could not un-see it — my Dad (who was my first woodworking instructor) is a bit of a doppelganger for Tage Frid. (Check out the picture below and compare it to the first picture of Tage Frid in this post) They both have very similar body shapes, taste in glasses, hairline and half smiles. I can’t talk too much because I look a lot like my Dad, I’m just the taller model at 6′-2″, so I suspect there will be a similar picture of me someday in the shop.

P.S. I never got to meet Tage Frid in person, he passed away while I was living out in Seattle but I would have loved to meet him. If anyone knew him personally I’d be curious to know a few things I haven’t been able to find online:

  • What happened to his shop, bench and tools? Are they in a museum somewhere? Did they go to his grandson?
  • Anyone have a picture of him in the classroom near the iconic benches he used to build?

Bolt Stretcher

What do you do when you need a very long bolt? Most hardware stores only stock bolts up to about 10″ or 12″ in the sizes most woodworkers use — 1/4″, 5/16″,  3/8″ and 1/2″ diameter.

Time to break out the bolt stretcher?

Assuming you don’t have such a mythical machine you can make your own longer bolts.

Start with some threaded rod and appropriately sized nuts…

Filing off the rough machined edge
Filing off the rough machined edge

File off any paint and machine/mill marks from the end of the threaded rod.

TIP: Place a nut a 1/2 in or so down onto the threaded rod before filing. Once you finish your filing you can remove the nut, and in the process will clean out the top threads which may have been deformed by the filing. Use should also use this technique when cutting threaded rod or bolts.

Why do I need such a long bolt?

In this case, I am building a workbench with a shoulder vise — this bolt helps make sure the massive vise screw does not blow out the wood joinery.

From Tage Frid Teaches Woodworking Volume 3 he suggest brazing a nut onto the end of a threaded rod, so I figured I’d give that a shot…

Mapp + Oxygen cutting and welding torch used for brazing
Mapp + Oxygen cutting and welding torch used for brazing

Time to break out the Mapp + Oxygen cutting/welding/brazing torch and some brazing rod which works much like solder. (Make sure you work in a well ventilated space and take all necessary safety precautions). Clean the mating surfaces and apply flux, then braze the nut to the threaded rod.

Brazed nut

Once it cools down you can file off any excess and use this newly made bolt. I’m no expert on welding, but the amount of hardware, time, and cleanup seemed excessive. Even with some filing, wire brush work and then some polishing I was not happy with the result — this end of the bolt would be visible in the finished bench. The coloring was off and now the nut looked a little off.

Is there another way?

I thought back to my days working on my Mustang and old F-150 and a remembered good old Locktite Red Threadlocker 271.

Locktite 271 Red Threadlocker
Locktite 271 Red Threadlocker

This little tube packs a heck of a grip. You apply some threadlocker on the threads and inside of the nut, put them together and let it cure for 24 hours. You would need to exceed 500 degrees F and 245 ft/lbs of torque in order to break the bond — so in other words, plenty of strength for my use.

Once cured I cut the bolt to length, filed off the hacksaw marks and cleaned up the leading threads using the tip above.

Now I have a nice custom sized bolt ready to go. If the need arises I hope you’ll give these techniques a try. If you do, let me know in the comments.

Where did all the paraffin wax go?

Paraffin wax has many uses around the shop and can often be found in my tool belt or shop apron. It’s something I often take for granted and rarely thought about until recently when I needed to replenish my stock and could not find it in any of the usual places…

The Hunt for Paraffin Wax:

I tried all the places I’d swear I had seen it before…

  • My local food stores — Shaws, Hannafords, Market Basket, and Stop and Shop
  • The big box stores — Target and Walmart. (Walmart even listed it in stock on the website with a product ID but after searching on my own nobody in the store had a clue about it and all claimed people regularly come into the store expecting them to have things the website says are in-stock but nowhere to be found)
  • Any other place I thought might reasonably have it — Walgreens, Rite-Aid, CVS, True Value

No luck.

The next best idea I had was to try some craft stores. Michael’s and AC Moore didn’t list it on their websites, but Hobby Lobby claimed to carry some but was sold out online. After clearing snow in the evening and feeling a bit of cabin fever I decided to give Hobby Lobby a try in person. After hunting around I finally found some in the candle-making section. Given all my hunting around I bought the last two 1lb blocks of paraffin — likely a lifetime supply for most woodworkers.

The Strategic Paraffin Wax Reserve
The Strategic Paraffin Wax Reserve

My favorite workshop uses for paraffin wax:

  • Lubricating screws — especially when driven into hard woods or when the screw made of a softer metal like brass it lubricates the threads and makes it easier to drive the screw. It does not affect the screws ability to hold in the wood, and is accomplished quickly by dragging the threads through a block of wax
  • As part of a workbench and similar shop finish — From Tage Frid and other sources he would dissolve paraffin with turpentine and boiled linseed oil and use it as a durable renewable workbench finish
  • Sealing metal and tools — by dipping them into melted paraffin
  • Lubricating planes and saw blades — a quick rub with some paraffin will help your planes and saws glide easily through the wood
  • Lubricating wood on wood moving parts — such as the tail and shoulder vises in a traditional workbench or on a drawer slide

Tips on working with paraffin:

  • You can cut up the block of wax into any size chunk you like using a large kitchen knife. I tend to use a block about the size of a hotel bar of soap
  • Be careful in the summer as it can melt in the sun, so be careful where you store it in warmer weather. I normally have an old Altoids tin in my toolbox to keep it from getting on everything
  • For making a finish be careful as paraffin is flammable so you’ll want to melt it in a double boiler or slice it very thin or use an old cheese grater to increase the surface area before mixing it with your solvent(s)

Where did all the paraffin wax go?

Paraffin wax is generally a bi-product of the gasoline production industry and is most often used to make candles, seal jars, and as a USDA approved coating for candies and some fruits and vegetables. For folks that used to can their own food they would often seal the jars with paraffin wax (often marketed as ‘Gulf Wax’ in the food store near the Ball Jars — it came in a white box and was cut neatly into 4 bars.) From looking online it seems the USDA has advised against using wax to seal your preserves and canning seems to be less popular in recent years as most food stores no longer stock Ball jars and that sort of thing — replaced by ziploc containers and other modern plastic disposable junk. Without the connection to food, I could see food stores dropping it from their shelves.

I suspect there might be more to the story, so if you have a better theory on why paraffin seems to be a lot harder to find, or have spotted some recently, please share your thoughts in the comments section below.

A Few Good Carpenters

A good carpenter can be hard to find. Many of us like to think that in earlier times there were was an abundance of exceptional carpenters, but this sort of lament is not a new phenomenon. Check out the interesting except below from the 1850s:

“The Author’s Experience.

These facts and reflections have been impressing themselves upon the mind of the Author of this work for twenty years past, while he has been serving the Public as a practical carpenter. During much of this time it has been his fortune to have large jobs on hand, employing many journeymen mechanics, who claimed to understand their trade, and demanded full wages. But it has been one of the most serious and oppressive of his cares, that these journeymen knew so little of their business.

Few Good Carpenters

They had, by habit, acquired the use of tools, and could perform a job of work after it had been laid out for them; but not more than one man in ten could himself lay out a frame readily and correctly.

Why Apprentices do not Learn

Now, it is not commonly because apprentices are unwilling to learn, or incapable of learning, that this is so, but it is because they have not the adequate instruction to enable them to become master-workmen.”

— William E. Bell ‘Carpentry Made Easy: The Science and Art of Framing’ (1858)

I think Bell’s comments ring as true today as they did when he wrote the above in 1858. I won’t focus on the lazy workmen uninterested in learning, but I will focus on those who want to keep learning new skills. As with many of life’s pursuits, you’ll get out of it what you put into it, and there is much to be learned if you know where to look.

Finding a good carpenter

Most of the best carpenters and woodworkers I know get the majority of their work via word of mouth and are booking months out at a time and  thus don’t have to invest much in marketing. If you’re looking to find one of the ‘few good carpenters’, ask around at a local woodworking school, shop, guild, club or friends and family for referrals and interview your next carpenter.

Learning More

One of the best ways to learn a woodworking skill is to take a class or workshop.

I have a few upcoming workshops this spring at the North Bennet Street School (details below) and there are some seats available if you are interested in joining me.

If the above does not appeal to you, there are several schools around the country that teach solid woodworking and carpentry skills. I encourage your to explore classes at any of these schools: The North Bennet Street School in Boston, The College of the Redwoods in California, The Heartwood School, The Shelter Institute in Maine, Philadelphia Furniture Workshop, The Kelly Mehler School of Woodworking, Phil Lowe’s Furniture Institute of MassachusettsConnecticut Valley School of Woodworking, and Roy Underhill’s The Woodwright’s School

If you’re not able to make it to one of the above schools there are scores of books that can help you along your woodworking journey. I think every carpenter would benefit from reading all 4 volumes of Audel’s Carpenter’s Guide, Tage Frid Teaches Woodworking Vol 1-3, Bell’s Carpentry Made Easy: The Science and Art of Framing, and Get Your House Right.

Woodworking is a life long journey and I hope that you will continue pursuing new aspects of the craft.

Balloon Framing

Between Timber Framing and modern Platform Framing was an intermediate style of framing a building called ‘Balloon Framing’.

Balloon Frame 3D Model
Figure 1: Balloon Frame 3D Model

This method of framing was radical for its time. Started around the 1830s and steadily gaining in popularity through the end of the 19th century Balloon framing ushered in a new generation of building supplies and builders who benefited from and drove the advent of ever cheaper machine made nails, consistent milled lumber, and more efficient transportation methods (Rail box-cars etc). Beyond the technological advancements in the materials production and transportation this building method caught on quickly as buildings framed in this manner could be built cheaply with non-skilled labor and common nails and tools, thus farmers and do-it-yourselfers could build what they needed with a far shallower learning curve when compared to all the advanced joinery traditional timber framing required. This was invaluable to frontier areas where traditional carpenters and joiners were in short supply.

Bell's Carpentry Made Easy Plate 4
Figure 2: Bell’s Carpentry Made Easy Plate 4

In the mid-west and plains states in particular you see a lot of balloon framed houses during this period as they had good access to the mills producing these building materials, a desire to quickly build and expand existing buildings and in some areas a dearth of heavy timber needed to build in the older styles. Even in more populated areas back east you’ll see many of the Shingle Style and Victorian homes and Triple-Deckers were framed this way, though certainly some more austere farm houses of this period were also framed in this manner as it was an economical way to build. If you look carefully at some of the design details you can see how tastes and designs changed to make use of the dominant building supplies of the time. You’ll see higher ceiling heights, various bump outs, towers etc that were more easily executed with this style of framing and in keeping with the prevailing styles of the day. (See Figure 3)

Figure 3: Mansard Victorian in Manchester NH

Balloon framing made use of common sized lumber coming from mills — the first real large scale use of 2x4s, 2x8s, 1x10s etc in framing a building and marked a transition from the heavy timbered buildings of the east coast of America and the ‘Old World’ that preceded it. In the earlier part of this period a 2×4 was actually 2″x4″ in some areas as opposed to the ‘nominal’ sizes we have today wherein a 2×4 is 1.5″x3.5″ by the time it makes it to a modern lumberyard, but that is a post for another day. The weight of the building was dispersed across a series of smaller consistent studs as opposed to a few heavy posts. Also notable was the fact that the studs ran from sill to plate, thus requiring the 2nd and 3rd floors to be ‘hung’ from the studs via ledger or ‘ribbon’ boards. (See Figures 2 and 4)

Bell's Carpentry Made Easy Plate 5
Figure 4: Bell’s Carpentry Made Easy Plate 5

A great period resource for information about Balloon Framing is William Bell’s “Carpentry Made Easy: The Science and Art of Framing”. While Bell was not the first author to extol the virtues of Balloon Framing he may have been one of the most prolific. His ‘Carpentry Made Easy’ book was published continuously from 1858-1904. 46 years is quiet a testament to the information he provided. The book’s longevity is largely due to how the information is provided. Bell starts with a detailed section on basic math and geometry for carpenters and the moves into framing. He covers Balloon Framing for homes and modest sized buildings and moves on to heavy timber framing for industrial buildings, bridges, spires and the like. Bell was a trained carpenter and joiner and speaks the reader in a clear and concise way that was agreeable to most carpenters. Bell goes into technical detail but did so in such a way that any reasonably skilled carpenter could take this information and apply it to the project at hand. His words still resonate well today — in fact using his descriptions I was able to build a detailed 3D model in Sketch-Up based on his instructions for how to build a Balloon Framed structure. (See Figures 1 and 5). I’m sure that many a house carpenter had a dog-eared copy of this book in their toolbox and regularly referred to it over the years.

How fast did this transition happen?

Like most major shifts in an industry the transition from Heavy Timber Framing to Balloon Framing did not happen over night. The word had to get out, it had to be evaluated, the supplies had to be ready and a host of macro-economic pressures had to come together in order to facilitate this change — a strong need to build economical housing for an exploding population etc. Like most things, some isolated or rural areas clung to the old ways for longer periods and some areas were more willing to try out these new techniques. Even cutting over in terms of technique was an evolutionary change. If you look closely at Figure 4 above you’ll see that the house shown there has Balloon Framed walls with a heavy timbered sill, which the author notes as the preferred way to go if heavy timber is available, as opposed to Figure 2 which shows a more traditional balloon framed sill made from 2x framing elements.

In broad terms this building method started in the 1830s, crescendo-ed during the 1880s-1930s giving way to modern Platform Framing which was an evolutionary advancement that built upon the strengths and lessons of this movement. Balloon Framing and it’s relative efficiencies greatly improved the living conditions of many Americans and others of modest means and the burgeoning middle class.

Balloon Frame Cutaway 3D Model
Figure 5: Balloon Frame Cutaway 3D Model To Show Joinery

Why did Balloon Framing disappear? Disadvantages and Demise

With Balloon Framing, you framed an entire wall at once from sill to top plate, thus requiring longer framing members. Once the wall was standing you needed to have ladders and scaffolding in order to ‘hang’ the upper floors from the ledger plates and studs. This required more labor compared to modern platform framing where each level builds upon the lower level, thus requiring less labor, scaffolding and smaller framing members.

In some larger Balloon Framed buildings you’d see some sagging towards central walls due to differential shrinking of the framing members — joists resting on ledger boards will move a different amount when compared to joists nailed into the side of as stud. This kind of differential can add up in a larger building and took time to manifest itself. (See Wikipedia here for a more detailed explanation)

While the above items are negatives for this system of framing the final nail in it’s coffin was how it performs in a fire. The inter-stud wall cavities that run from sill to plate worked like a chimney flue and helped to rapidly spread fire throughout a Balloon Framed building. To counter this, fire blocking can be installed between each floor, but this was labor consuming to install and not quite as good as the fire resistance you’ll see in a Platform Framed building. Even today when filling out an application for homeowners insurance you’ll often see questions related to this kind of framing.

What replaced Balloon Framing?

Around the 1930s the death toll and property loss data was starting to add up and folks looked to rectify the situation. The solution was Platform Framing. In a nutshell you’d build a platform of sill, joists, rim joists and sub-flooring, use this as a platform to build the walls for one floor, you’d tilt up and nail off the walls, then build another platform on top of that until you top out your building. This method required less labor, shorter framing members and by breaking up the wall cavities at each floor provided better fire resistance.  After World War II the post war building boom accelerated the need for even more housing and faster build completion times. At this time we started to see the introduction of studs 16″ to accommodate sheet goods (Plywood and later OSB) in regular sizes as a replacement for more labor and material intensive traditional sheathing. And in a similar manner vinyl siting replaced genuine clapboards etc etc until you get to present day building materials and practices.

Conclusion

We don’t often see or hear much about Balloon Framing today as it has fallen out of favor in the building community, but it’s impact can be felt today in any Platform Framed structure that benefited from all the lessons learned by this earlier incarnation of efficient home building. I hope that the next time you are examining the framing of a Balloon Framed structure you’ll take a look and see what lessons it can teach you.

Take care,

P.S. If you’d like to read William Bell’s “Carpentry Made Easy: The Science and Art of Framing” (1858) you can get a copy from the Toolemera Press here. It was a great read with interesting sections on timber framing, compound roof joinery, bridge-building, spire making and other interesting building topics above and beyond the Balloon Framing and carpenter’s geometry I mention in this article.

Treenails, Trunnels, Pins and Pegs

Treenails, Trunnels, Pins and Pegs — all terms used to describe the wooden nail-like fastener used in timber frame construction. I needed to make a large number of them for an upcoming project and thought you might also enjoy seeing what it takes to make these deceptively simple looking pins.

(1) White Oak and Hard Maple stock ripped, thickness planed and jointed

Where did all those names come from?

Like most things that predate modern recorded history I’ve read many conflicting theories on where these terms came from, so what I relay here is based on my own experiences in this field; your mileage may vary. Timber framing dates back thousands of years and can be found in early civilizations around the world in many different forms. What all these structures had in common was the joining of heavy timbers using traditional joinery and large mortise an tenon joints that were pinned together using large wood fasteners.

These fasteners are known by a lot of colloquial names, the most common of which I describe in this post. Most literally treenails (or trenails in some places) is the term for nails made from a tree. Trunnels is derived from the pronunciation of treenails and at times reserved for larger treenails used in very large buildings or ships, sometimes even wedged so they do not back out. Pegs tends to be a more modern term for treenails and pins tends to be used for smaller scale work though many timber framers I know today use it regularly. Having said all this I’ve heard all of these terms used inter-changeably at times by both novices and seasoned professionals, so feel free to use the term(s) that best suit your work and locale.

The bottom line is ‘a pin by any other name will hold your building together just as well.‘ (provided you heed my tips below 😉 )

How do you go about making these pins?

Traditionally pins were split out of green wood, shaved down with a draw knife and shave horse and allowed to season. Then touched up again when dry. Since I have to make a few hundred of these, being a practical modern joiner I will make use of my table saw and some high quality kiln dried lumber. Most of the stresses in a timber frame are carried by the joints and not the pins, and white oak is very resistant to shearing forces so I am not worried about the wood not being split out for this usage. (I’m building a square rule, late 19th century style frame from milled eastern white pine, so by that point the pins likely were made the same way I go about it)

For the scale of timber framed buildings I generally work on — homes, barns and sheds, I’m usually using a 7/8″ ships auger bit to drill holes for pins. Most tenons I work with are generally 1.5″-2″ thick eastern white pine and based on experience and reference tables I’ve found this size to work well for me.

I learned to timber frame while at NBSS and with that my framing has a proclivity for historic precedents. The historic buildings I work on all had octagoned pegs which worked well for hundreds of years and can be made more easily when compared to the expensive turned pegs you see some modern supply houses offer for upwards of $2 each. For a draw bored joint, I feel the octagon pegs look better and hold better compared to the CNC turned pins. (More on that later)

Making octagons out of the square blanks
(3) Making octagons out of the square blanks

1.) I start off by milling down my rough 4/4 white oak stock to be 7/8″ thick, then I joint an edge on each board (See photo 1). I then crosscut each board to be about 30-3/8″ long. (Each of these boards should yield 3 sets of 10″ long pegs)

2.) Next I rip each of those boards into 7/8″ square sticks (See photo 2)

3.) Tilt the blade on your table to 45″ and turn each of those square blanks into an octagon. The use of feather-boards will help you be consistent. (See photo 3)

5.) At this point you’ll quickly see how many pin blanks it takes to make even a modest building. (In this case a 12’x24′ large shed/small barn) (See photo 5)

Using the hewing bench, carpenter's axe and timber framing chisel to taper the ends of each pin
(6) Using the hewing bench, carpenter’s axe and timber framing chisel to taper the ends of each pin

6.) Now it’s over to the hewing bench to taper the leading ends of the pin blanks. I usually rough off the wood with my capenter’s axe and touch things up with a timber framing chisel. I find it helps to get the cut started with the tool and bang them both (peg and tool) in unison on the hewing bench. The downward momentum drives the tool through the wood with a minimal expenditure of energy — important when you have a few hundred of these to complete.

Completed pins
(7) Completed pins

7.) I usually taper the first 2″ or so of the pin. You do not need to be overly concerned with trying to make the pins look like a sharpened pencil. You just need to knock off the corners to help guide the pin through the draw-bored joint.  Anything beyond that is to suit the design aesthetic you are going for. (Some folks will want to cut the ends off a pin in the house, so all the more reason to only do what you need to do with them)

8.) Sit back and enjoy your work. Take a deep breath and repeat steps 1-7 all over again to make try pins. Try pins are slightly thinner pins used when test fitting your timber frame. I make them from hard maple for two reasons — I can visually differentiate them from the oak and the smooth hard maple is easily removed when the test fitting is complete. For this frame using 7/8″ Oak pins I make the try pins from 3/4″ hard maple stock. They are made the same way as their larger brethren.

Why are they octagons?

By making a 7/8″ octagon pin and driving it into a 7/8″ round hole the corners will bite into the wood and keep the the pin securely seated.  (The diagonals across the 7/8″ octagon are slightly longer than 7/8″.) This is why you want to use smaller try-pins during test fitting, this way you are not deforming/stretching the holes before the frame is raised.

Tips for a high quality timber framing pin:

  • Use kiln dried pins with a green wood frame. Use green pins with a dried frame
  • I use most often use White Oak pins with green Eastern White Pine frames
  • I use Hard Maple Try Pins during test fittings (try pins should be 1/8″ smaller than your final pins)
  • Octagon your pin stock so that it properly bites into the joint
  • Taper the ends of your pins so they will easily enter the draw bored joints
  • Don’t stress too much about the tapering
  • Avoid the machine turned pins — I dislike the look, the cost (~$2 each), holding power, fact that they are not historical etc

Where can I learn more about timber framing?

  • Join the Timber Framer’s Guild (www.tfguild.org) and read the many good publications they have
  • Read any of the books by Jack Sobon, Ted Benson or Ed Levin on the topic of Timber Framing
  • Take a class in timber framing at The North Bennet Street School (with Rich Friberg or me), or at the Heartwood School in Western MA

The next time you are in a barn or timber framed building I hope that you will take a moment to examine the pins holding the joinery together.

Hewing Bench Revisited (Already)

After living with my new hewing bench for a few weeks I finally got around to using the other half of the log. I’m glad things worked out this way as I made some modest improvements based on our time together.

Original bench on the right, revised model on the left

The original bench was fairly solid — it could hold me standing on it and didn’t bounce around when I would strike it in a downward motion — but when I’d do something heavy and lateral I could feel what felt like a tiny bit of flex in the the legs.

At the time I ripped down a 2×3 to make the legs roughly sized to the 1″ ship auger bit which was the largest I had on hand, but I worried about the 1-1/8″ legs being too spindly. The mental image of the legs being too spindly haunted me, so for this second time out I decided to rectify that issue.

Improvements:

  • Thicker legs (1-1/2″ square) with a more pronounced shoulders (this way the legs don’t add to any unnecessary wedging/splitting pressure and no matter how much hammering takes place on top of the bench the legs are maxed out in how deep they will go into the top of the bench)
  • Legs splayed in both directions to be that much more stable
Leveling the legs

Beyond the modest improvements called out above, I otherwise built it the same way as the first hewing bench. (Wedged tenons, wax sealed end grain, leveled legs etc)

Completed benches. They can also work well as a pair of saw horses.

The Verdict:
The new bench is rock solid and will be a workhorse in the shop. The new legs are nice and stiff. Having a pair of these benches in the shop has already come in handy as you’ll see in the next post.

Take care,
