Ruminations
Fetch the Board Stretcher
Happy New Year, everyone! I realized I missed my usual “6am Eastern on New Years Day” post. I think that’s because I went to an actual party and didn’t get to bed right at 730pm like I have for as long as this blog existed. But anyway…
A while ago, I obtained an old growth slab of what I believe is Slash Pine (one of the species of Southern Yellow Pine) from a reclamation sawmill. It’s about 16 inches wide, 90 inches long, and after flattening is still a solid 3 1/2″ thick. It’s mostly flat at this point, anyway. I actually made an impromptu router sled because it’s so damned hard (the resin long ago crystallized and, between that and the barn grit in the checks, it was eating O1 steel for breakfast). This slab will make a wonderful workbench top once I laminate a fascia board along the front edge and square the ends, though.
Another workbench, you say? Well yes, of course. I’ve been working on my 8 foot maple Nicholson which I made in the thick of the pandemic. It’s got the nicest leg vise I’ve made (it’s angled, uses a cog and screw instead of a pin board, and opens and closes very smoothly). But I’m kind of over front aprons again; it makes using bench dogs in the top too difficult, even if the apron is great for edge planing long, wide boards. And I have just the one workbench at home after giving all the others away. A second wouldn’t hurt.
This new bench will be in the Shaker style, like at Hancock Shaker Village. Leg vise, tail vise, sliding deadman, some drawers underneath. In fact, I’ve already made the leg assemblies. But unlike the Shakers, this bench will knock down (like a Moravian workbench). And I have a linear bearing and a 1 1/2″ hardened steel shaft to use as a parallel guide for the leg vise instead of a pin board (or even a cog and screw or crisscross). McMaster-Carr is the best.
When making the recess for the linear bearing, though, I didn’t have a good way to make a 2 3/8″ hole. So I chopped it out octagonally. And it was scruffy and didn’t fit well and I had to shim it. All of which ate at my brain and caused me to set the whole project aside for a while.
I’ve finally come back to it. And it still eats my brain.
And what is a fellow to do when a bad bench installation is ruining a good time? Cut the offending portion of the leg off and add some wood back on, of course. About that…
First step was to saw off the offending area and square up the end grain. And also dig out and prepare an offcut of the same species that has a decent grain match. If I had access to a Festool Domino, this would essentially be the end of the process. Four dominos and some glue: Bob’s your uncle.
But absent a Festool Domino, how does one join two boards, end grain to end grain? Finger joints are probably the best option, because of the large amount of long grain gluing surface. For a hand tool guy like me, that’s essentially a bridle joint. I think in this application, it would be strongest if the mortise was in the remaining leg and the tenon on the added piece. I almost made bridle guides, but that probably would have taken longer than just sawing and paring.
Once the mortise was nicely pared to the lines, I roughed out a tenon and finessed it to a friction fit with a router plane. Remember to ease the inner parts of the mortise to leave room for glue on the mating surfaces. A dry fit looked like so:
Will a 1″x1″ tenon (with 7/8″ mortise walls) be strong enough for a front leg of a workbench, even with TiteBond Thick & Quick PVA? Fuck if I know. But this is poplar, which doesn’t split easily, so I think I’ll be okay. I plan to add a trio of 3/8 oak pegs as reinforcement along the length of the tenon, which should help. Maybe a couple of metal mending plates too just for luck. But I think it will be strong enough, even without pegs, as long as whatever parallel guide I use for the leg vise doesn’t bear just on the new wood.
To be clear, I almost bought a Festool Domino today. But I’m glad I stayed strong and didn’t. Not that having a Festool Domino is bad; I just kind of enjoy doing things the hard way. And I do think this fix is a good solution and should stand the test of time.
Or not. Fuck if I know.

Building on a Theme
If anyone asks me what kind of workbench they should build when just getting into woodworking, I have only one answer: a Mike Siemsen-style Naked Woodworker English workbench. The video is an excellent step by step (my only complaint is that it doesn’t show cutting the lap joints on the lower stretchers for the leg assemblies). But more importantly, it is a design that a true beginner with a small set of tools can knock together with a reasonable chance of success.
I have built a few such workbenches. But I’ve noticed that pretty much all of my shop furniture pieces end up in the Naked Woodworker style too. Id est, glue and screw laminating various pieces to create the lap joints and other connections without having to cut any real joinery.
One of the important things about Mike’s design is leaving the top rails a bit proud (shown above), so they can be leveled with a hand plane to form a flat plane to attach the tabletop. This is very useful when using rough construction lumber but still wanting precision in the final piece.
Abrupt segue:
I fully subscribe to the hypothesis that the best woodworking hand tool is a band saw. I can absolutely spit a gauge line with a hand saw (although it has taken practice) and I am able to saw a perfect shoulder with a back saw (with a little bit of chisel paring). But a well tuned band saw just makes things go quicker (at least the cheek part of the cut).
I have the most basic version of a band saw with a coarse (skip tooth) blade, but it can cut as fine of joinery as I need. If I could go back in time, I would have bought this thing so much sooner. And now, it moves around.
Sometimes I wonder if having a bandsaw will atrophy my hand sawing skills. But then I need to resaw some 16/4 stock and I forget about my previous qualms.
And that, my friends, is the true meaning of Christmas.

Apartment Woodworking: Year 10 Retrospective (Part 2)
For several years, the floor of my workshop has been the OSB top of DriCore tongue and groove subfloor squares. DriCore is a modern miracle (not a sponsor, just to be clear) and going from working on the bare concrete of the basement to a fully insulated, slightly cushioned wood floor was nothing short of staggering. Not to mention eliminating the risk of a falling chisel needing a full regrind by landing edge down to the concrete. I’ve recently added some tongue and groove laminate on top of the DriCore which, even though it’s darker in color, it has actually brightened the room (I assume because the albedo of the shiner floor is higher than the OSB of the DriCore squares).
Since adding the laminate floor, I’ve been working off my 98″ Nicholson workbench, made of hard maple. This bench has by far the best leg vise I’ve ever made. It works smoothly, doesn’t bind and the foot operated cog gets real momentum because of the heft (8/4 white oak). It’s still too big for the space, and honestly could use another 2″ of benchtop depth (being a hair under 22″). But it’s the only bench currently in the room. My last buddy to buy a house needs a better workbench than the one I made him pre-pandemic. So I’m giving him my proper Moravian knockdown bench. And with my outdoor workbench neatly stacked in the garage, I’ve got room (and time) to make another full size workbench. But more on that later.
I like the vise on the maple Nicholson when cutting tenons. Unlike a pinboard variety, the cog and screw parallel guide easily adjusts between holding the tenon board widthwise to cut the tenon shoulders and cheeks and holding the mortise board lengthwise to chop and pare out the mortise. Although, in fairness, I’ve been using a hollow chisel mortiser more and more these days to do the mortise chopping.
All those tenons are currently for a new sharpening station. Essentially a trestle table about the size of a sawhorse (and, quite frankly, patterned off a Krenov-style sawhorse). The frame is made of scrap Douglas Fir 2×4 leftover from the lumber rack build and the top will be Spruce offcuts from a planting table built up in Vermont. When it’s done, it will also have a drawer for saw sharpening gear. I might even use full extension, metal drawer glides that can open from either side.
I had missed having a dedicated sharpening station that stashes in the corner. When I was working on the green Moravian, the maple Nicholson was pushed up against the wall and the sharpening station was all the way at the end. Besides having to squeeze in between my tool chest and whatever I was working on, the rest if the workbench top got super cluttered all the time. This new station will hold everything it needs to without any extra room to accumulate detritus. It will also be more accessible.
After I finish the sharpening station, the next thing is to take down the lumber rack on the right wall. It barely stores any lumber and just collects clutter (seeing a theme here?). I’ll move whatever lumber (mostly reclaimed red pine) is on it to the new lumber rack (by, unironically, hanging the racks on the back side of the lumber rack posts). That will free up more than a foot of usable floor space (and force me to organize the other crap on the racks currently).
That’s all for now. Will share some pictures when the sharpening station is finished.

Efficient Fettling
Before the new year, I essentially finished the carcass on a new, streamlined traveling tool chest. I had made a low profile Dutch Tool Chest fairly recently that, unfortunately, didn’t quite work out for its intended purpose. Long story short, I miscalculated the size of the lower compartment and nothing quite fits without effort. Another inch or so and it would be fine. It’s also a bit wider than it needs to be.
So that means it’s time to make another one!
This isn’t a post about the new chest itself, but here are some quick details: 9/16″ Eastern White Pine carcass; 3/4″ EWP tongue and groove back boards; Southern Yellow Pine lock, battens and catches; Tremont Nail cut nails throughout. Overall size 24″ x 23″ x 12″. Lower compartment is 9″ high.
As I was making the lid (always the worst part of any tool chest build), I decided to start painting the case. Then, after three coats of paint, I dry fit the lid and discovered the top of the well is rather twisted. The front right corner was about 3/32″ higher than it should have been, so the lid rocked pretty badly. If you’ve never had to level the top of a Dutch Tool Chest after assembly, know that you can’t just continuously plane the top edge like you would with a traditional square box where it’s all edge grain. If you’re not careful, you’ll ram into the end grain of the side board and risk spelching the case side. And it’s awkward.
Instead, whenever I need to level a cross grain corner joint, I start with a chisel. Mark the depth with a gauge and chop, bevel down, until you scallop out enough of the end grain where the two boards meet to give clearance to your plane bed. You can now plane down the the long grain of the front board to depth without slamming into the end grain of the side board. Then, just take down the hump in the end grain of side board until it’s straight and flush with the new corner height. Once everything is about there, one long continuous pass starting from the far front corner and ending at the near back corner finishes it off.
Moral of the story: check for twist before you apply three coats of paint. Or, better yet, before you attach the front board at all.

Low Bench Leg Joinery
I’ve been making low benches (both workbenches and general furniture) for a while now and I’d like to talk about the various ways to join the legs to the top. In my experience, some are better or worse than others, depending on several factors, including: (i) the purpose of the finished piece, (ii) the thickness of the benchtop, (iii) the materials used, and (iv) the tools available.
Let’s discuss several choices to join the legs to the top (I swear this is not a clip show):
First, we have cylindrical through tenons. The tenon can be hand carved, turned on a lathe or made with a round tenon cutter (like for rustic joinery). The mortise is bored with a large auger bit or some other boring bit.
Next, we have conical through tenons. The tenon is hand carved with a drawknife or plane and then typically refined with a special tapered tenon cutter. The mortise is bored with a smaller bit and enlarged with a tapered reamer.
In addition, we have rectilinear through tenons, which can be cut with regular edge tools. The tenon is sawed to shape with an angled shoulder. The mortise is chopped out with a chisel. No boring tools needed.
Finally, legs can be joined with notched lap joints. The tenon is sawed at an angle with a birds mouth shoulder. The mortise is just a dado in the side of the top. Also no boring tools needed.
There is also the tapered sliding dovetail used on Roy Underhill’s Timber Bench, but that’s outside the scope of this article.
Let’s take these in order. This is just my opinion based on experience; others may have their own takes.
Round Tenons
Pros:
- Relatively easy to cut: You just need an augur/boring bit of appropriate diameter (and a bit of skill to follow an angle) to cut the tenon. For the tenon, either use a lathe or log joinery tenon cutter or employ a few common hand tools (saws, chisels, spokeshave, rasps, sand paper) to round off the tenon and taper the shoulder.
- Strong: Full thickness tenons, glued and secured with wedges, form a secure and durable joint.
Cons:
- Hard to correct: If you mess up the angle or wallow out the mortise too much, you’re stuck with it. There is no correcting after the fact.
- Limited sizes available: If you want a 2″ round tenon, you need to find a 2″ boring bit to cut the mortise. And a drill or brace that can use the damn thing without releasing the blue smoke (or tearing a UCL).
- Certain materials work better: Leg stock needs to be bone dry, otherwise the tenon may shrink and need to be re-wedged in the future. Also, ideally, the wedges are made of something even harder than the legs. Finally, 2x dimensional lumber may not be thick enough for a sturdy leg.
- Cosmetics: To me, full size round tenons just look off. If the angles are done right (so the exit holes are proper circles and not wallowed out ovals) and you use a contrasting wood for the wedges, they can be beautiful. But there are too many variables for me.
Tapered Tenons
Pros:
- Relatively easy to cut: Same as above, except you need a tapered reamer to make the tapered mortise and typically want a matching tapered tenon cutter to refine the tenon (both are generally available from the usual woodworking suppliers).
- Self-tightening: As you put weight on the legs, the tapered tenon will seat even further into the joint. The leg stock should still be bone dry, but as long as your legs are made of something equal to or harder than the top, the joint can sort itself out over time.
- Easy to correct: Unlike the cylindrical tenon, where you are stuck with the hole you bored (including any wonky angles), you can correct the angles using the tapered reamer. Just take it slow and check often.
Cons:
- Less strong: The tapered tenon has less material making contact with the top and the wedge is not full width, so for a low workbench or a sitting bench for more than one person, you may need to add a cross rail to each pair of legs stabilize things.
- Requires specialized equipment: As noted above, you need at least one piece of special equipment (a tapered reamer) to make the mortise. Refining the tapered tenon without the tapered tenon cutter is doable but takes some practice.
Rectilinear Through Tenons
Pros:
- Easy to cut: No specialized tools needed. A chisel, a mallet, a bevel gauge (or a block of wood cut to the right angle), and some patience will give you a clean and precise hole (that you can further refine with a file or rasp). I like to bore out most of the waste with an augur bit and pare down to lines, but this is ultimately just a square or rectangular mortise.
- Strong: Of all the joints described, this one has the most material forming the tenon.
- Customizable: You’re only limited by the size of the stock (not the size of the boring tool), so this joint can be used for everything from a footstool to a full size standing workbench. I would imagine this is the joint used in the workbench shown in Plate IX, Figure 68 of the marquetry entry in Diderot’s Encyclopedie.
- Cosmetics: Rectangular tenons wedged at 90 degrees or square tenons wedged at 45 degrees are very pleasing to my eye. I think they look the best of all of the through tenons.
Cons:
- Complex layout: Unlike cylindrical or conical tenons, you have to actually lay out both sides of the mortise. This requires carrying compound angles around to the other face. You’ll need to not only S4S the top but also square the ends.
- Harder to correct: If you overshoot your lines, the only option is to make the tenon larger (which is easy if you overshoot side to side, but much harder front to back).
Notched Lap Joints
Pros:
- Simple to cut: This joint can be cut with one saw and one chisel. Even the compound angled version is not particular difficult to work out. There is a reason why saw benches are the quintessential intro woodworking course.
- Any material works: 2x dimensional softwood lumber from the home center is perfectly acceptable for the legs. Using thinner material for the top (such as 2x dimensional softwood lumber) does not materially weaken the joint, either.
- Versatile: When using a narrower than ideal top, this joint can be used on the back legs to extend the footprint to a stable depth.
Cons:
- Weak without reinforcement: As an external joint, glue alone is unlikely to be enough for a lasting joint. Metal fasteners and gussets are required to keep this joint together long term.
- Legs protrude beyond the top: Another drawback to the external joint, the legs will likely be in the way for some sawing and other operations. You can fix this by laminating on boards after the legs are attached, making a de facto rectilinear through tenon.
- Cosmetics: This is generally not a furniture grade joint. There are certain instances where it can be attractive. But most often, you’ll be using this joint for workshop stuff.
So what do you think? Did I miss anything in the pros and cons lists? Have I ruined everything forever?
I mean, yeah. Of course I have. But maybe not because of this article.

This Time of Year
Around these parts (Fairfield County, Connecticut), it’s warming up. This time of year, I’m finally able to drag my workbench outside and get real some woodworking done. My outside workbench, now with new slab and tool tray, is in fact getting quite a workout. I can get a bunch done with just a pair of holdfasts and a few clamps to secure the work. Proper vises are great. But they are not absolutely necessary if you’re not cutting English style dovetails.
One of my goals for this year is mastering tapered tenon joinery for staked furniture. Or at least becoming facile with it. I have experimented with reamer and tapered tenon cutter before, but in situations where strength was not a primary concern. Chairs and stools are higher leverage projects (literally and figuratively) than credenza bases and side tables.
So with a nice weekend, I might as well make some chips on the lawn with a drawknife and spokeshave to prepare some leg stock for refinement. I resolved to take the tapers further than I usually do off the drawknife. I also spent more time with the spokeshave before introducing the tapered tenon cutter. I’m not sure it was faster than doing more rough work, but the results are more consistent than my prior work.
These legs are ash, which was split off from a small timber that checked badly while it was drying I’d have preferred the leg blanks be closer to 2″ square, but you work with that you’ve got (these are 1.65″ square). I’ll add some stretchers between the pairs of legs for extra rigidity.
I am also working through some old boards, some from as early as 2014 that I’ve been dragging from shop to shop all these years. Among that is a red oak 2×12 (nominal size 1.75 x 11.25). It’s about 65 inches long and I could never bring myself to cut it down into smaller boards. So as I figure out how to be precise with compound angled joinery, I might as well make another low bench. The top had cupped and bowed pretty badly so by the time it was flattened, it was only 1.5″ thick. You may not think half an inch of red oak means that much, but it does. This is a sitting bench, not a low workbench, so the little bit of flex means added comfort. But if this were to live in the shop, it would need a 2×4 glued and screwed to the underside for extra support.
I do all my boring and reaming by hand with a brace, so it’s much harder to overshoot an angle or a depth with the reamer that way. But it’s still important to check your angles and go slow. Doing so will ensure the exit holes on the top (ie, visible) of the seat are of consistent size and shape. In the end, some irregularities aren’t fatal to the structural soundness of the piece. But looking nice is important too.
So this is a very long way of saying, if it’s nice outside, I will drag a workbench outside and get a tan while doing some rougher work. It’s harder to rake shavings off the lawn than to sweep them up off the floor.
But such is life.

One for Me
I wonder sometimes if others have similar woodworking experiences to me. Namely, that just after finishing a piece for myself, a friend or relative will ask for it instead.
Now I try to live my life as Tolkien describes Aule, the Smith (“the delight and pride of Aulë is in the deed of making, and in the thing made, and neither in possession nor in his own mastery; wherefore he gives and hoards not, and is free from care, passing ever on to some new work.”). And I like to think that quote describes me pretty well. So many pieces end up in others’ hands, even those pieces purpose built for me, if the giftee seems particularly keen on it.
For that reason, I have been sans dining table for some time. Every time I finish one, it seems it’s claimed within a few weeks. But not this time. At least not yet.
The style itself feels a bit tacky to me. It’s a home center butcher block tabletop (birch) and the legs are poplar. Nice, clear, straight grained poplar (left over from the base of my Moravian Workbench), but still. The table is an inch too low (at 27.75″) because I was just using what’s on hand. The legs themselves are round tenoned and wedged into thick blocks. Essentially making leg brackets. Which are just screwed into the underside with torx deck screws.
I’ve been joking on social media that it’s a lazy table (third laziest, in fact). But I don’t think that’s quite right. The legs themselves are tapered octagons. And the mortises are bored at 12.5 degrees and when attached have about a 30 degree sight line. I didn’t make a full base or dovetail the legs into the tabletop or something like that. But it still took some thought and problem solving.
But that’s not really the point. Calling it lazy seems to me a bit like gatekeeping. And that’s not something I support in any field, especially hobby woodworking. All that should matter is that a person made a thing and had fun doing it (or at least is pleased with the result). I personally don’t use a table saw or a router table, but I also personally don’t give a fuck if someone else does.
There are enough litmus tests in this life. My only one is “do you have a thing that you love to do?” And as long as that thing is not hunting endangered animals for sport, you do you, bud.
And if you do hunt endangered animals for sport, you can fuck all the way off and unfollow me.
Please and thank you.

Batchin’ ’em Out
If you’ve been here more than once, you know I’m a hand tool guy. To be clear, I do have power tools that complement primarily hand tool work. My lunchbox thickness planer does the donkey work once there is a tried and true reference face and a squared reference edge off the jointer plane. A double bevel compound miter saw quickly cuts stock to rough length. And you can pry my benchtop hollow chisel mortiser from my cold, dead hands. I also have a small drill press (that at this point is used exclusively for accurate drawboring), a collection of battery-powered DIY tools (a drill driver, a circular saw and a random orbital sander), and a trim router kit for when I’ve truly given up on things.
But doing hand work efficiently is more than just leveraging power when, as and if it makes sense. When there are multiple parts to cut (there always are), it helps to think like a one-person assembly line. Each step in the assembly line is a repeated task. Sure, variety is a the spice of life. But just like a blade and fence setup at the table saw, you want to set it once, do all the cuts, then move on. It’s the same thing for body mechanics at the workbench.
So let’s talk about tapered octagon legs by hand.
The first two tapers on each piece (on opposite sides) go pretty quickly in the face vise. If you work to opposite sides, the other profile is still square and therefore easily held in the vise (in my case, a leg vise). Do that eight times.
If you have a twin screw vise that can hold tapers securely, great. Stay at the face vise. But I don’t, so I move to the tail vise. Pinched between the dogs, the legs sit flush to the bench on the tapers I had just planed to make a square taper on all faces. Do that eight times.
Now lay out the octagon(s). If you have a lathe and will taper across the entire length, you’re nearly done at the workbench. But I don’t have a lathe and I like to start the taper where the round tenon ends, so in addition to the octagon at the foot, I also lay out an octagon on the top where the tenon will go. A cradle jig that goes in the tail vise holds the work and I taper from square down to octagon at the foot and also from square down to an octagon at the top. Do that thirty-two times (16 long tapers and 16 short tapers).
That short taper makes it easier to center the round tenon cutter I have for my drill driver, btw. I use a 1 1/2″ tenon cutter, but that’s just a rough cut. With chisel, spokeshave and rasp I take that round tenon down to 1 3/8″ to ensure it’s centered on the blank (it rarely is straight off the tenon cutter). It also helps to bore a 1 3/8″ hole in some hardwood (or at least wood that is harder than your blank) with the bit you’ll use for the mortise to test the fit now and again. Do this four times.
Finally, I go back to the corners (where they were tapered from square to octagon) and plane in the full tapered octagon from the tenon to the foot. I find taking the facets down evenly first (so the facet is parallel from the tenon to the foot), and then incrementally increasing the facet width at the top near the tenon by counting strokes, works best. Again, if you taper the full length, this step is unnecessary.
It goes without saying, but I did one leg first to work out the process and then batched out the other three with the process described above. Are they perfect? Of course not. But we are not machines (and should not strive to be machines). And I enjoy the hand made aesthetic far more than machine-wrought perfection.
There is a great rhythm one can get into when batching out parts at the bench. Hehe, batching.

Most Important Woodworking Website
There is a website I go to (almost) every day when I’m in the shop. A website with the most important and useful woodworking insights. Truly, it is an indispensable resource for my woodworking needs.
That website: http://www.carbidedepot.com/formulas-trigright.asp
A trigonometry calculator.
This is not a joke. Imagine rough cutting a board too short and only learning it after you’re trying to level the legs.
A travesty, for sure.
