Portable, sturdy and simple to construct, these had been used for quite a lot of duties.
Many of the implausible furnishings types of the Middle Ages have disappeared and have been changed by items which can be extra complicated however not essentially higher.
One of my favorites is the early trestle desk. It’s three items – a high and two sawhorse-like issues – that may be immediately damaged down, moved or saved. The kind reveals up in early work as getting used for all the pieces within the family: making pasta, butchering, surgical procedure, writing, woodworking and effective eating.
Last yr I constructed two of those tables for our dwelling and have been delighted with how they appear and performance. One desk is a roomy desk. The different desk is used to accommodate further dinner company, serve wine on the entrance garden and wrap presents.
Not solely are the tables versatile, they’re easy and fast to construct. The trestles are constructed utilizing “staked” furnishings expertise, basically a conical mortise-and-tenon joint that’s extra forgiving than its square-shouldered cousin. Each 8″-wide trestle high receives three legs for stability.
The two entrance legs are linked by an ornamental stretcher, which options Arabic and Mughal motifs. If this stretcher doesn’t attraction to you, substitute a easy turned rung or a stretcher that’s pierced with Gothic shapes.
The tabletop is a straightforward flat panel made out of three pine 2x12s. The tabletop doesn’t should be fairly as a result of it sometimes was coated by a linen tablecloth.
Do not let the compound geometry of this venture intimidate you. While it appears complicated, even a newbie can handle it. Construction begins with the legs.
Tapers on Tapers on Legs
The legs taper on all 4 faces so they’re 15⁄8” sq. on the flooring and 11⁄4“sq. on the high. This is definitely completed with a jack aircraft adopted by a jointer aircraft. Mark out the completed dimension on the tops of the legs and jack aircraft the tapers. Clean up these instrument marks with a jointer aircraft.
Next is chopping the tapered conical tenon on high of the six legs. The tenon is made utilizing a reasonable 5⁄8” tapered tenon cutter from Lee Valley Tools that works precisely like a pencil sharpener.
To put together every leg for the tenon cutter, it’s good to tough in a taper on the highest 31⁄2” of every leg to make it simpler for the tenon cutter. You can tough within the tenon by whittling it, turning it or utilizing a drawknife.
The objective is to create a 11⁄8” diameter on the base of the tenon that tapers to about 5⁄8” on the tip. I used a lathe, which is quick. After roughing within the tenon, shave it to ultimate dimension with the tapered tenon cutter.
Trestle Tops & Geometry
The trestle tops are the interface between the legs and the tabletop. While you’ll be able to depart them as square-edged boards, outdated work sometimes present them with barely curved edges (and even what seem like halves of logs). I used a jack aircraft to spherical over the lengthy edges and ends of the trestle tops, so the underside was 7″ broad x 241⁄2” lengthy.
To lay out the places of the mortises, first strike a centerline on the underside of the trestle high. The mortises for the 2 entrance legs are 21⁄2” from the ends of the trestle high and a pair of″ in from the sides. The mortise for the one third leg is centered on the underside and is 21⁄2” from the top. (See the drawing on the high of the following web page.)
After laying out the mortise places, draw a baseline that connects the 2 mortise places on the entrance of the trestle high. Then use a protractor to strike a “sightline” from every mortise that’s 14.6° off the baseline (examine the picture under if you’re scratching your head). The sightline is the pencil line that your bevel sq. will sit on as you bore the mortise.
Set a bevel sq. for 15.5° off of 90° and tape its inventory (deal with) to your sightline. Chuck a 5⁄8” auger bit into your brace. You are going to drill a gap via the trestle high that’s parallel to the blade of your bevel sq..
Stand immediately according to the bevel sq. and put the tip of the auger on the mortise location. Tilt the brace to the identical angle because the bevel sq.’s blade and crank the brace till the spurs are buried about 1⁄4” into the work. Stop and test your angle. Crank the brace just a few extra occasions and test your work, adjusting the angle as vital.
Once you’re about 1″ into the wooden your angle is pretty locked. If you’re off, don’t fret; you’ll be able to repair that if you ream the opening to a conical form.
Crank till the lead screw pokes out the opposite facet of the board. Flip the board over and end the lower by boring from the opposite facet.
The single rear leg is easier. The sightline is the centerline on the trestle high. Change the angle of the bevel sq. to 4° off 90° and tape it to the sightline for the rear leg. Bore the opening in the identical method because the entrance legs.

Ream the Mortises
Lee Valley makes a reasonable tapered reamer that matches the angle of its tapered tenon cutter. This reamer might be chucked right into a brace or an electrical drill – I want a corded drill for the unfailing torque.
Some students have guessed that these conical mortises may need been burned to form. While I like hearth as a lot as the following overgrown boy, the tapered reamer is extra predictable.
Before you ream the mortises, use your tapered tenon cutter to make a dummy tenon on a 1″ dowel. It’s simpler to substantiate the angle of your reamer by checking it towards a cylindrical dowel than towards a tapered leg.
Set your bevel sq. to the identical angle you used for boring the 5⁄8” holes and tape it to the sightline. Ream every gap briefly burst for higher management. After 4 or 5 rotations of the reamer, take away the instrument and place the dummy leg within the gap.
Ream the opening till the opening is 11⁄8” broad. You might be shocked how rapidly this goes, so be cautious as you start as a result of it’s simple to overshoot your mark. Ream all of the mortises. Check your work by knocking the legs into their mortises and see in the event that they line up like they need to. If issues are off somewhat, don’t despair; there’s nonetheless one other likelihood to make issues look proper.
The tenons are glued and wedged into the trestle tops. To make life simpler, do this stuff earlier than you slather the glue.
■ Trim the tops of the legs so that they protrude 1⁄8” above the highest of the trestle high.
■ Saw a 11⁄4“-deep kerf within the high of every tapered tenon. The kerf receives a wedge. The kerf needs to be perpendicular to the grain of the trestle high in order that the wedge won’t cut up the work.
■ Make some hardwood wedges with a shallow included angle – about 4° is true.
■ For every trestle, have two clamps and a flat board on the prepared.
If you will add a flat ornamental stretcher to the entrance legs, it’s good to maintain the entrance faces of the legs in the identical aircraft if you glue up. That’s what the clamps and flat board are for.
Paint glue within the mortises and drive the legs into their mortises. Then clamp the entrance two legs into the identical aircraft utilizing the clamp and flat board. Don’t freak if this makes the legs somewhat cockeyed in comparison with the trestle high; it (most likely) won’t be noticeable.
Drive the wedges into the kerfs within the tops of the tenons. After the glue dries, trim the tenons and wedges flush to the tops of the trestle tops.
After meeting, it’s good to lower the legs to their ultimate size and get the tops of the 2 trestles in the identical aircraft. The easiest method to do that is with the drill press. Yes, the drill press.
The drill press has a desk that’s infinitely adjustable for peak. I clamped a pencil to the desk and cranked it so the pencil tip was 28″ from the ground. Then I turned the trestles the other way up on the store flooring and rubbed the legs towards the tip of the pencil. Simple.
Saw the legs to ultimate size utilizing a crosscut backsaw. Clean up the toes with a rasp or aircraft.
The Bottom Stretcher
The ornamental backside stretcher is a little bit of a head scratcher. Should its grain run vertical or horizontal? I settled on vertical, which I feel will make for a stronger trestle and make the ornamental particulars much less prone to snap off. I additionally assume it’s the greatest answer to cope with the wooden motion of the stretcher and the trestle high throughout the long term.
Lay out the sample in your stretcher panel and lower it to form with a coping noticed. Clean off the sawblade marks with a rasp.
The stretcher is each glued and nailed to the legs. I used 4d wrought-head nails from a blacksmith for authenticity. You can substitute lower rosehead nails if you’re on a funds.
To connect the stretcher, glue it to the legs then trim away any overhang. Then lay out your pilot holes for the nails. Drill pilots and drive the nails in.
If the flat and ornamental stretcher doesn’t attraction to you, think about using a easy spherical one that’s 3⁄4” in diameter with 1⁄2“-diameter tenons. You’ll have to bore mortises within the legs for this stretcher. But that is simpler than you assume.
To bore these mortises, you’ll want a 1⁄2” spade bit, a bit extension and a drill. Why a spade bit? It has an extended middle spur, which permits you some extra room to steer on this software. Also, you’ll be able to simply grind down the perimeters of the spade bit to make your mortise undersized if want be.
Chuck the bit and extension collectively and mark the lifeless middle of the mortise on one of many flat faces of one of many legs.
Place a bit of tape on the spade bit that’s 15⁄16” from the spurs that lower the circumference of the opening. That would be the depth of the mortise.
Place the lead level of the spade bit on the centerpoint of the leg the place the mortise will go. Rotate the leg a tad within the mortise so you’re coming into that face perpendicularly. Trust your self a bit on this.
Line up the shaft of the bit extension with the marks for the mortise on the alternative leg.
Run the drill as much as full velocity with out plunging into the leg. Once the bit is working at full velocity, plunge slowly into the leg. Repeat the identical process for the mortise within the reverse leg. Yes, it truly is that simple.
Glue the stretcher in if you assemble the bases.
The high is merely a plank, often about 5′ to 10′ lengthy in accordance with examples in work. I made mine 7′ lengthy to suit the again of my truck so I may simply transport the desk.
My high is three yellow pine 2x12s which can be edge-glued. I left the underside tough from traversing it with my jack aircraft. I exploit this as a worksurface as issues are a lot much less prone to slide round. On the opposite face, I planed and completed the highest easy so it might be used for eating by merely flipping the worksurface over.
We haven’t any option to know the way these items had been completed. They may have been left naked, oiled, waxed or painted. Some of the work present the tables as darkish, which might be the wooden, a pigment or the results of the smoky interiors of houses within the Middle Ages. In different work these tables seem like they haven’t any end or a transparent end.
I used a do-it-yourself oil/varnish mix that I wiped on. The oil gave it somewhat colour; the varnish gave it somewhat safety towards spills.
The finish results of this minimal end is that the tables look shockingly fashionable, particularly to individuals who don’t know they’re kinds from the 15th century.
While I anticipated the tables to look modern, I used to be shocked as to how helpful they’re in a contemporary, cellular society. I had deliberate on promoting these tables to prospects (maybe some denizens of our native Renaissance truthful), however they’ve turn into such part of the material of our dwelling I don’t assume I can half with them. In truth, I’m now making one other one these tables – this time with a maple high – to make use of as a desk in my new workspace. That high will get a conventional Danish end made out of cleaning soap flakes – a topic about which you’ll learn proper right here.
