The Abyss Stares Back

It’s come to my attention that I’ve been misquoting Nietzsche for some time (even though I can spell his name first try, every time).  From “Beyond Good and Evil”, Aphorism 146 states:

He who fights with monsters should look to it that he himself does not become a monster. And if you gaze long into an abyss, the abyss also gazes into you.  

This well-known quote from the oft-misunderstood German philosopher is undoubtedly the genesis of the Harvey Dent quote in “The Dark Knight (2008)”:

You either die a hero, or you live long enough to see yourself become the villain.

But, because I, like The Batman, am not a hero, let’s allow the abyss gaze into me for a moment.

IMG_20190815_070945.jpg

So many mortises, I feel like I haven’t cut a dovetail in forever.

Last week and over the weekend, I did in fact dig deep and bear down.  I chopped four new mortises in the leg frames for the reclaimed console table and planed and joined the two long rails.  After all was said and done, there were 20 drawbores in the undercarriage, plus another 4 in the joints between the front legs and the main slab.  And then I painted the entire undercarriage with “Linen” milk paint.

IMG_20190817_142650-1.jpg

Not to be confused with “Antique White” or “Seagull”.

But even the best laid plans don’t work out perfectly, so there was plenty of time for things to go pear shaped.  But I was pleasantly surprised when everything came together pretty much straight and square. 24 drawbores, not a single snapped dowel.  Not even a stripped screw on the tabletop connectors.

The picture below doesn’t do it justice, but the piece feels light and graceful.  And in the mid-afternoon light of a north facing window, it evokes the “Islands of New England” feel I was hoping for.  I’m building a shallow tray out of 3/4″ poplar to fill out the rest of the table top, which will be painted in “Coastal Blue” milk paint and nailed on.  The face edge and ends of the main slab will also be painted that color.  The only bare wood will be the top and back edge of the main slab.

IMG_20190817_154856.jpg

A shelf, if added, will also be painted “Coastal Blue”.

You may recall that I had a tripartite plan:

  • Drawbored mortise and tenon joints for the long stretchers.  ✔
  • Reinforce main slab with a board glued on below.  X
  • Skip the shelf.  ✔

As someone once said, two out of three ain’t bad.  And that’s one more batch of reclaimed lumber off the pile. We’ll see if I ever get to that leg vise and/or fixed deadman.

Unrelated, I also ended up putting an end cap on the pine bench top extension to the Stent Panel workbench.  I think it looks a ton better, even if it’s not functionally necessary.  It’s not a great color match at this point, but there are worse things in life.

IMG_20190806_195633.jpg

I can finally sleep at night!

Now, if I could just figure out how to do the same thing on the left side of the bench.

Staring into the Abyss

There comes a point in every build where I have to ask myself: do I dig deep and bear down, or take the easy way out?  I am ashamed to admit it’s barely better than a 50/50 split over time.

I’ve been working for a while on a rather large “console table” made entirely of reclaimed lumber from past projects.  The undercarriage is hard maple reclaimed from one of my earliest woodworking projects: a platform bed.  Even after planing and sanding, you can still see the remnants of gross home center stain in the pores.

IMG_20190810_081949.jpg

Looks green, but is actually “mahogany”.

If the general shape looks familiar, it should.  And I have, to this point, worked hard and done it right.  All the joints are mortise and tenon, drawbored with 7/16 dowels with relatively aggressive offset.  Solid as a rock.  The undercarriage will be painted to cover up the gross discoloration and some tear out of wild grain.

The tabletop, however, will be ash.  Specifically, ash reclaimed from the back wing of my Stent Panel workbench.  Reflattened and otherwise cleaned up a bit, it’s 80″ long, 10″ wide and a hair under 1 7/8″ thick.  That’s more than half of the overall tabletop area and solid enough for whatever light duty it may pull as it sits under a north-facing window in my dining room.

IMG_20190811_201003.jpg

It’s pretty enough for its intended purpose.

The tenons on the tops of the front legs will be drawbored into mortises in the slab.  Some DIY tabletop connectors should combine to make a stout connection between the frame and the tabletop.  All while allowing for seasonal wood movement.  Some sort of full length tool well will fill out the rest of the table top, but probably won’t be good for much other than collecting junk.

IMG_20190812_205728_01.jpg

Tabletop connectors are good enough when there won’t be much wracking force.

At this point, the mortises are cut into the slab and everything fits together nicely.  But, as always happens, I now have a choice. There will definitely be stretchers on this table.  It would otherwise be too wobbly with just a single tenon and tabletop connector on each leg frame.  But how do I connect the stretchers?

Do I meticulously mark and pare shoulder lines for proper mortise and tenon joints (like the leg frames) for maximum strength and consistent aesthetic? Or do I skimp on time and process and lap the stretchers into the front and back legs, which would certainly be strong enough and look just fine?

And once the stretchers are attached, should I add a jack board mortised between the front stretcher and the underside of the tabletop to add a bit more rigidity in the middle and act as a fixed deadman?  Or do I just glue a strip of maple to the underside of the tabletop to reinforce it more discreetly?

What about a shelf?  Do I add one at all?  If so, is it birch plywood banded in maple or solid wood reclaimed from some source?

Each of these choices affects the amount of effort and time required to finish this project.

IMG_20190813_065758.jpg

Here I am, staring into the abyss.

So here is my hot-take (for now):

  • Drawbored mortise and tenon joints connect the long stretchers to the legs.
  • Tabletop reinforced with additional lamination below.
  • No shelf, for now.  I may also add a loose deadman one day.

Everything is a give and a take in hobby woodworking. Doubly so in small-space hobby woodworking.  But, sometimes, there is a middle ground between “dig deep, bear down” and “easy way out”.

Back to Back to Back

I’m not quite ready to abandon my upright Stent Panel Workbench for the low, sitting variety.  But I am ready to correct something that’s bugged me ever since I finished the workbench in the first place: the back wing.  It never stayed flat on its own, let alone in plane with the main slab of the bench.  There is clearly some design flaw, even though I allowed for wood movement and ample support with three posts mortised into the slab.  I’ll re-use the wing (which is 86″ x 10″ x 2″ ash) for another project.

IMG_20190722_082238.jpg

I need more 1″ holdfast holes.

The main slab of the workbench is only 12.5″ wide.  That’s nothing to scoff at, but it’s not nearly enough real estate for tasks like gluing up panels or project assembly.  And there is pretty much no place to set down tools so they are close at hand.  So first up is a tool tray that spans half the area where the wing used to be.  After much deliberation, I’ve approached this a bit like a Dutch tool chest.  Dovetails at the bottom corners for maximum strength, nailed on back.  In 3/4″ poplar, because there was a very nice piece of 1×10 at the home center when I was buying some more 1×12 white pine for general building purposes.

IMG_20190723_081206.jpg

Reasonably consistent color for poplar, and a decent color match to ash once oiled.

The finished tool tray is just a hair under 37″ wide (the posts themselves are exactly 37″ apart) and 6″ deep.  There is 3.5″ of clearance below the benchtop.  This is plenty for a bench plane on its side and all the other tools I’d like close at hand.  Speaking of which, I decided to attach the tool well to the left side of the bench (the end with the leg vise), which seems like the best place to keep tools at hand.

IMG_20190723_081525.jpg

Because if it can’t fit a hand plane clear of the workbench top, it’s not a good tool tray.

There are a few ways I could have hung the tool tray to the bench.  But the simplest and easiest was to add some runners to the ends so it just hangs on the posts.  The posts are not perfectly in wind, so I clamped the tool tray to the bench and nailed the runners in the right position, rather than squaring them initially and planing them down to fit.  Some small blocks, nailed onto the posts, keep the tray from sliding away from the slab.

IMG_20190724_070658.jpg

Don’t tell anyone, but I used the 18 gauge brad nailer to attach the runners and blocks.

The ends of the tool tray are in plane with the workbench slab.  This was intentional, as originally I intended entirely replace the back wing with two tool trays.  But after working on the bench with the tool tray for a few days, it became very apparent that I needed at least part of the bench to be solid for the full 20″ of depth.

From 9 months or so of working on this bench, it’s become clear that the wing doesn’t need to be terribly stout.  It certainly doesn’t need to be 2″ ash reinforced with 2″ angle iron.  So instead I grabbed an otherwise somewhat useless 2″ pine off cut that’s lapped onto the posts.  There are a few wire brad nails acting like dowels to support the seam with the main slab and a couple more wire brads through the board into the posts to keep everything in place.  Net it, this board can move much more freely with seasonal expansion and contraction than the old wing could.  But it will be easily replaceable if I get neurotic and replace it with ash again (which, let’s face it, I definitely will).

IMG_20190728_090157.jpg

And the color match isn’t terrible, either.

For optics, but not functionality, I will probably nail a board to the end of the extension to bring it flush with the right end of the bench (and provide a bit more resistance to cupping, like a breadboard end).  Absolutely nothing ever happens all the way at that back corner.  It’s just to make it prettier.  I could do the same thing at the back right corner, but the end of the tray (which is flush with the bench top) is already in line with the last bench dog hole, so it’s not strictly necessary either.

I unfortunately can’t tell if the color match is getting better or worse with a second coat of Tung Oil.  Maybe I just have to open the blinds and let the sun shine in for a couple weeks.

IMG_20190801_091903.jpg

Or paint the whole thing black!

This is a good time to mention that 36.25″ is a bit too high for comfortable hand planing at my height (I’m 5’10”).  Even if it is better for sawing and chopping.  So I’ll eventually trim about 1″ off the ends of the legs.  Which is easier said than done, as the back legs are angled.

But I’ll give it a try and report back.

Budget Twin Screw (Moxon) Vise

A good twin screw vise can do many tasks.  When clamped to the edge of a bench top, it can be used as a proper face vise for dovetailing or other joinery.  Sitting free on a bench top, it can restrain an assembly for driving wedges or be a third hand for safely splitting tenons.  In a pinch, it can even take the place of a machinist vise for basic metalworking (although I would recommend vacuuming it off when you’re done, as metal shavings are anathema to woodworking tools).

But a good twin screw vise doesn’t have to cost a fortune.  I mean, it can, if that’s what you’re into (with wooden screws or prefab hardware and whatnot).  But it doesn’t have to.  In fact, all it really takes is about US$13 worth of home center hardware and some off cuts.

IMG_20190704_100838.jpg

That is some straight grain, eh?

There are two typical ways to make a vise screw work without a garter that attaches the movable jaw directly to the screw.  You can affix the screw to the back jaw, and turn a nut to sock down on the moving jaw.  Like the Benchcrafted Moxon Vise.  Or you can affix the nut to the back jaw and use the screw hub to sock down on the moving jaw.  Like the Lake Erie Moxon Vise.  For this, let’s do the latter.  There is a third way, which I’ll cover briefly below.

Start with the front jaw.  Now I am sure there are people who can use a brace and bit and drill a perfectly perpendicular hole.  But I can’t, so I used the drill press.  The screw should be relatively snug in the hole (phrasing?).  This threaded rod is about 3/4″ and a 3/4″ forstner bit was just tight enough.  Inset the holes at least 1 1/2″ from the ends of the front jaw for strength.  Some people elongate their holes to permit clamping irregular work.  I don’t.

IMG_20190704_101856.jpg

Also chamfer the holes.

It’s super important when making a twin screw vise that the holes line up.  So clamp the front jaw to the back jaw and use the same drill bit to transfer the center of the hole into the back jaw.  I should mention that the back jaw is about 4″ longer than the front jaw for some clearance each end when clamping to the bench.  Otherwise, the clamps get in the way of the work.

After you’ve bored the hole in the back jaw, put both jaws back together, insert the threaded rod, tighten up a nut on both sides of the jaws and trace around the nut on the back jaw with a marking knife.  Then chop down to the lines about three fourths of the height of the nut.  Repeat for the other nut and use a small bit of epoxy to affix the nuts to the back jaw.

IMG_20190704_104905.jpg

I do not know if the orientation matters for strength, but the epoxy will help.

Balance is an important part of any twin screw vise.  Even with the narrower front jaw, it’s likely the vise won’t balance itself with the front jaw hanging completely off the bench.  So I typically add an extension to the back jaw flush to the work surface.  It adds weight and stability and is a convenient place to put down your pencil or marking knife when cutting joints.  Glue should be all you need, but maybe add a screw or two through the inner jaw to make sure everything stays put long term.

IMG_20190704_150036.jpg

Some not-as-straight grain.

When the glue dries, you’ll have a functional vise.  There is something called a “rod coupling nut” which is really just an elongated nut.  You could use a couple of these as floating hubs and the vise would work just fine.  It wouldn’t be super comfortable (you’d have to turn the threaded rod by hand) and the nuts would wear into the front jaw over time, but it will hold.  Want proof?

IMG_20190704_172042.jpg

Proof.

You could also affix one of those rod coupling nuts to the end of each threaded rod and also be done.  But I like wooden screw hubs, so let’s do that.  Start with square stock and drill into the end of the hub.  I used the drill press, but you could do this by hand.  Just clamp the work across all faces to prevent splitting.

IMG_20190705_084133.jpg

Drill press vise for safety.

I think it took more time wedging underneath the benchtop to get it perfectly level in all directions than it took for the epoxy to set.  Be careful not to make too much of a mess, but excess epoxy can be used to reinforce the end grain of the hub (that wears against the face grain of the outer jaw).  When the epoxy was set, I drilled through the hub across the grain and pinned through the threaded rod with a 1/8″ steel rod (fixed with superglue).  Probably not necessary, but who knows what that zinc coating will do long term?

IMG_20190705_091822.jpg

If these were raw steel, the epoxy would be more than enough.

Then shape the hubs as you see fit.  I put a small chamfer on each corner of the hub for starts.  I have a feeling it’ll get down to roughly octagonal by the time it’s done.  I don’t like round hubs.

And that’s it.  Clamp it to your workbench and have at some joinery.  Maybe add a coat of penetrating oil finish to all surfaces other than the inside faces of the jaws.  I may glue some leather to the outer jaw to increase grip, but it’s not strictly necessary.

 

IMG_20190705_095947.jpg

That’s the steel pin through the handle.

If you’ve never made a vise before, this is a good way to figure it out.

I am, at this point, nearing US$100 into the low plywood workbench project, but it feel like it’s pretty much done.  I need to bore a few more holes in the bench top (and make a few more dogs) but that’s more planning than labor.

After undertaking this experiment, I have some thoughts.  But first, now that the vise is done, it’s time to make a little tool chest on this workbench!

Or, whatever.

Plywood Roman Workbench (Part 4)

Only by working on a low bench, like the plywood roman workbench, can you truly understand what they’re all about.  And after a week or so, I can definitely say there is something to finding the correct height for your body.  I’m just a shade over 5′ 10″ tall and I find 19 1/4″ to be the right height for saw benches.  And of the two low workbenches I’ve built in the past, one was 19 1/4″ and the other was 19 1/2″.  Both are very comfortable heights for me.  I build sitting benches within this range as well.  It’s the height from the ground to the bottom of my kneecap.

IMG_20190414_101920.jpg

Like this one.

But I’ve been working with the plywood Roman workbench propped up on my existing saw benches, which are already 19 1/4″ high.  That means the working height of the plywood Roman workbench is currently over 22″ high.  WAY too high for me to work comfortably.  I’m on my tiptoes most of the time, which is at least a good calf workout.  So let’s make some mini sawhorses out of construction grade 2×4’s to bring the slab to the correct working height.

IMG_20190701_170729.jpg

This is where we are going.

I always start with the math:

First, stand straight up with your feet flat on the floor and measure from the floor to the bottom of your kneecap with a tape measure. That is your overall target height (in my case, 19.25″).  Second, subtract the thickness of the plywood slab (2.875″ for me).  So I need to raise the slab 16.375″ (or 16 3/8″) off the ground.  Let’s round up to 16 1/2″ to make the math easy.

In the United States, construction lumber may be called “two by’s”, but it is really 1 1/2″ thick.  I dug through the stacks at the local Death Star and found two, 10 foot long 2×4’s in Douglas Fir that were relatively straight, relatively clear and relatively dry.  You could, in theory, get everything you need from a couple of eight footers, but why risk it?

Each mini sawhorse consists of six boards, all cut from 2×4’s:

  • Two foot boards (20″ long or so)
  • One top crossbeam (16″ long or so) – the freer of knots, the better
  • One lower stretcher (cut to fit, but around 14″ long)
  • Two vertical posts (total height of the sawhorse, minus 1″ [or 15.5″ in my case]) – these should come from the clearest sections of the lumber.  No knots at all, if possible.

Start by preparing the boards.  If your stock is straight and square and out of twist already, give it a quick smoothing pass and proceed to step two.  If not, and you’re feeling like a machinist, plane a reference face and square up a reference edge, then bring the opposite face and opposite edge into parallel.  I only had to take off about 1/16″ of total thickness on each board, so I’m sticking to the round numbers for purposes of this guide.

IMG_20190629_134111.jpg

Face mark, square mark, grain direction.  Every time.

Each post connects to the foot with a 1/2″ through tenon.  For the mortise, bore with a 1/2″ bit and pare to the lines, or chop with a chisel, up to you.  I chopped with a 1/2″ chisel to keep my skills up.  I also prefer to split my tenons, rather than saw down the cheeks.  But it is precarious work to split tenons without a vise.  After everything is fit, shorten each tenon to about 1/8″ less than the thickness of the foot board to give some clearance when it sits flat.

IMG_20190630_072302.jpg

One of two.

With one of the posts firmly seated into its foot, measure up to the total height of the finished sawhorse, minus 1″.  Cut off the post at this line and mark and use it to transfer the mark the other post (while in its mortise) .  This should ensure the two leg assembles are close to or exactly the same height.  Now, assemble each leg assembly with glue.  I drawbored these mortises and tenons too, but it’s not necessary.  Nails or even screws would be just fine to reinforce the joint.

IMG_20190630_105410.jpg

I think this shot was pre-drawboring.

The top beam attaches to the posts with dadoes that are inset from each end of the beam by the same distance the post is inset from the outside of the foot (in my case, 1″).  Determine the depth of the dadoes by subtracting from the overall thickness of the beam the height you need the beam to rise above the leg assemblies to get your final height (in my case, about 1/2″ dado depth).  Do your best to get tight dadoes, but they will be reinforced with dowels after the glue dries.  Err on the side of too narrow, as the construction lumber will compress.

IMG_20190630_180012.jpg

With dadoes seated.

The stretcher connects to the legs with lap joints.  You can use the finished top beam to transfer the distance between the shoulders of the lap joints.  I trimmed the lap joints to be flush with the outside of the posts, but that’s not strictly necessary.  I didn’t get a good picture of the lap joint process, but take a look here.

Glue the top beam onto the posts and seat the stretcher in place while the glue dries.  This will help keep everything square during glue up.  Then glue the stretcher to both the legs and the feet.  After the glue dried, I drove a pair of dowels through the top beam into the posts and couple of nails through the lap joint on the stretcher into the legs.  This should help with any wracking (front to back and side to side).

And then do it all over again.

IMG_20190704_062549.jpg

One is somewhat heavier than the other because they’re made from different 2×4’s.

I’ll be taking a slight detour in the next post to make some more workholding for future projects.

For now, Happy Birthday, America!

Plywood Roman Workbench (Part 3)

From my experience, a large portion of work holding when using a low workbench is sitting on the work.  But any good workbench for hand tool work needs at a minimum a planing stop for hand planing and a bench hook for sawing.  So let’s add both at the same time through a pair of bench dogs at one end of the newly-squared plywood slab.  Fair warning, the list of tools needed is going to increase from this point on.

IMG_20190626_131727.jpg

This is pretty much all you need for most woodworking.

Let’s begin with locating the dog holes.  In my experience, a single point planing stop will work without re-positioning the wood for boards up to about 5″ wide.  So on this bench, I spaced the dog holes at 5 1/2″ on center, equally spaced from each edge.   4″ from the end seems about right as well, so the dogs can be used as a bench hook in either direction.

I used a brace and bit to bore the holes, but a drill driver works just fine.  Use the bit that is the same size as the dowel you purchased (mine are 3/4″).  Do your best to bore the holes vertically, although if you’re going to err, hopefully err on the side of angled toward you.

 

IMG_20190626_080555.jpg

Two squares make boring true much easier.

Yes, this is a workbench, but don’t bore all the way through in one shot and break out the underside.  One day, you’ll probably flip the slab over and breakout is unsightly.  Instead, stop when the point of the bit just pokes through, then flip over the slab and finish the hole from the other direction.  That way, you’ll have clean exit holes on each face.  Then, break the edges of the hole with a countersink bit in a drill driver, a chamfer bit or roundover bit in a router, or with some coarse sandpaper.

IMG_20190626_084359.jpg

I prefer chamfer to roundover for dog holes.

Now, let’s make bench dogs.  You should feel free to purchase commercially made metal bench dogs and be done with it.  I like the brass ones from Lee Valley and use them on my main workbench.  But hand made bench dogs work great too.  Start with lengths of dowel that are 2″ longer than your slab is thick.  In my case, 5″.  Now, jam the dowel into the hole you just bored.  I had to use my main workbench because the dowel I purchased was apparently a bit undersized to the hole I bored.

IMG_20190626_075520.jpg

Nice, straight grain.

Orientation of the relief on the bench dog is critical to strength and grip.  Align the growth rings left to right, and mark a pencil line top to bottom that is about 1/4″ from the right side (left side, if you are left-handed).  Now, saw down that line, angled in about 2 degrees, to a cut depth of 1″ or so.  Then crosscut the waste away.  I used my leg vise but you can just clamp the dog to the slab or crosscut while the peg is vertical in the hole.  Be sure to ease the hard edges of the dog with some sandpaper of any medium grit.

IMG_20190626_075711.jpg

That’s literally all there is to it.

If your bench dog is snug in the dog hole but moves with light mallet taps, proceed to the next paragraph.  If the fit is too tight, thin the diameter of the dog a bit with some medium grit sandpaper, checking the fit as you go.  If the dogs fit loosely, like mine were, maybe buy some cheap brass bullet catches for cabinet doors or check out this Paul Sellers how-to on making wire springs for bench dogs (it starts at about the 11 minute mark).  If you use bullet catches, make sure to locate them in a place where they will catch when the dog is both up and down.  You’ll see what I mean.

Add a coat of Boiled Linseed Oil or Tung Oil (whatever you used for the bench top, honestly) and you’re done.

IMG_20190626_082808.jpg

Bullet catches are useful for a bunch of applications, honestly.

Once the oil finish is dry, pop in the dogs and have at some face and edge planing.

IMG_20190626_130413.jpg

One advantage to having two bench dogs instead of a single planing stop is you can crosscut boards using both pegs as a bench hook.  Like so:

IMG_20190626_130624.jpg

Goodbye, knot!

The slab now has all the workholding you’ll need to make two mini saw horses to replace the milk crates or buckets that you’ve been working on to this point.

I just finished up the prototype using just the slab with two bench dogs as my work surface.  I’m pleased enough with the design that I’ll replicate it for the second one.

IMG_20190701_170729.jpg

Basically 1/2 scale to full size saw horses.

But more on that later.

Fits and Starts, Part II

Life can sometimes feel like a series of unfinished woodworking projects.  I start with an idea and the best intentions, and something goes off the rails.  In this case, it’s the under-workbench cabinet from last year.  The case has been sitting around, taking up space in my workshop since before American Thanksgiving.  But, unable to get back to sleep around 330am, I decided to push it forward and nail on the tongue-and-groove case back.

IMG_20190522_070113.jpg

Is that the end of the tunnel or the train?

This was never meant to be fine furniture.  In fact, it’s sized to fit underneath my Stent Panel workbench.  But I’ve gotten used to keeping my saw benches there, so I’ve finally confirmed its new purpose as furniture.  Some 16″ hairpin legs will raise the deck to 36″.  The perfect height for a dry bar.

IMG_20190522_070126.jpg

Some detail on the T&G back boards.

The plan was always to dado in some shelves in one cubbyhole and add a door to the other.  I don’t think that’s the best use of the space if it’s not workshop storage.  Instead, I will add a drawer to the top of each cubbyhole and use the space beneath each drawer for book storage.  I probably should have done that stuff before nailing on the backboards, but when has patience ever been my first option?

IMG_20190522_070222.jpg

Probably overkill for something that won’t be mounted to a wall.

There is something profound about the process of laying out, drilling and driving nails.  I usually listen to music while woodworking, but I always forget to hit play with dividers in hand.  I guess it’s so I can hear the change in tone as the nail clears the pilot hole and bites the wood.

IMG_20190522_055300.jpg

Cut nails where they won’t be seen.  Die forged where they will.

It’s been a few months since I’ve cut any half blind dovetails.  They go quicker in pine, but tend to be a bit more ragged than in hardwoods.  I have a fine dovetail saw (20 tpi) that works well for those tasks.

It’s around here somewhere, anyway.

Getting it Together (the Short Version)

I had planned to write this whole post about wood movement and using tabletop anchors in finalizing the bathroom vanity project, but there is nothing I could say that Paul Sellers hasn’t said already (and better).

So, if you don’t know about wooden tabletop connectors, stop what you’re doing and go watch this Paul Sellers video.   After that, if you are so inclined, enjoy this picture of the undercarriage of the vanity.  Tabletop connectors not only hold the top on the vanity, but also anchor the entire assembly to the wall stud.

IMG_20190320_074131.jpg

Deep sinks are a PITA but worth it in the end.

Don’t forget to use brass fasteners in white oak.  Steel and white oak do not play nicely together.

If a coherent philosophy exists in my woodworking, it’s this: “Why build when you can overbuild?”.  Or, perhaps, it’s “Could we? (not should we)?”.  Either way, it’s resulted in the most hilariously stout bathroom vanity of all time.

Glamour shot just before the sinks go in.

The entire thing is quartersawn white oak.  The leg frames are entirely 8/4″ stock (final thickness of about 1 15/16″) and the top is 6/4″ stock (final thickness of just over 1 1/4″).  Everything is stub tenoned and drawbored with 3/8″ birch dowels and Titebond 1.  The long rails are even double drawbored front and back.

It’s not a workbench, but it might as well be.

I chose to drawbore the mortise and tenon joints for two reasons.  First, there are no lengthwise lower stretchers, so it needed the extra rigidity.  Any lower shelf I make will just sit on top of the short rails of the leg frames.  But, more importantly, I don’t own any 60″ clamps so clamping this thing together would have been awkward and unreliable.

Pre-assembly, pre-finish.

Drawboring also makes assembly less stressful.  You can move the constituent pieces individually and then assemble in situ at a leisurely pace. Sure: the assembled frame probably would have made it through the door from the hallway anyway.  But who knows (and why risk it)?

The net result is a piece of furniture with a frame that will never come apart.  Even if I want it to.

How the tabletop connects to the frame is a different story altogether, though.  More on that later.

Alternatives to Fighting

In progressing the standing desk build, I had to make a design choice regarding how to attach the back stretcher. But, more importantly, I had a practical choice to make. The angle of the back leg on each of the two frames is slightly off. Call it half a degree or so. Near the top of the assembly, there is no appreciable difference. 30″ or so down the legs, though, it’s nearly 3/16″ off.

I could, in theory, modify the cheek depth on one of the tenons and cant it very slightly to correct for this discrepancy. Or I could just run the stretcher near the top where the bag legs are, for all practical purposes, parallel. And if I’m doing that, why not in my impatience just lap a dovetail?

Because of course dovetails.

Half-lapped dovetails are an interesting joint. I personally find them aesthetically displeasing, even when executed perfectly. But they provide a mechanical resistance against tensile force that in other joints would require some sort of fastener (dowels, screws or bolts). And, like the comparable joints (mortise and tenon, half lap joint), they have significant long grain to long grain glue surface for maximum strength.

Plus, I find them rather easy to cut once you dial in the compound angle.

Ugly or not, this particular joint is not only on the back of the assembly, so I don’t have to every look at it again. Plus, it will be painted. So I’m happy with the choice.

Now I just have to make the top.

Have I mentioned that Eastern White Pine is just the best? Because it is.
