bookmark_borderMeasure and Mark Redux

So what did the little collection of tools on a stool look like at the end of the project?

Bit of a mess

You can see I’ve added a sashigane, a larger ruler, a socket awl and a drilling block. The awl is useful for making a hole where the brad point of a drill bit can go to keep the bit from skating around as the hole gets started. The block keeps the drill bit perpendicular to the surface of the wood as the hole is drilled. The other black plastic thing is a right-angle block.

bookmark_borderAssembling a Sawhorse

I realized that it might be a little mysterious how those sawhorses I made actually fit together. Here are some assembly instructions.

1) Collect the pieces

You’re going to need two feet, two legs, one stretcher, one top, two pegs, and two wedges. The legs have a wide end and a narrow end. The feet have one mortise in their top sides. The top has two mortises in its underside. you’re also going to need a small hammer or mallet.

2) The foot bone is connected to the leg bone

Insert the wide tenon of one leg into the mortise in the top side of one foot. It is very tempting to hammer the top of the narrow tenon, but this may mash it making ti difficult to insert later, so resist the urge.

3) Add ye peg

Use the mallet to hammer a peg all the way through the sideways through-mortise in the foot. These are designed to be drawbores, which means that the mortise in the leg does not line up perfectly with the mortises in the foot. This makes it more difficult to hammer in the peg, but as you do so it draws the joint tighter.

4) Play it again

Repeat those steps to assemble a second leg/foot combo.

5) Add stretcher between legs

Insert the stretcher between the two legs, sliding the tenon at each end of the stretcher entirely through the sideways mortise in each leg. Note that the wide dimension of the 2×4 is vertical. The mortises and tenons are square, so make sure the stretcher isn’t sideways.There’s no “inside” or “outside” to the legs, so whichever way fits better, just go with it.

6) Wedge the stretcher

Insert a wedge into the through mortises that run vertically through the tenons at each end of the stretcher. Hammer these nice and snug, or the resulting horse will be wobbly.

7) Add the top

Slide the top down onto the tenons at the narrow ends of the legs.There should be enough tension in the assembly to hold the top firmly in place once the horse is assembled. If there is too much tension, and the top just won’t go on, remove the wedges to release the tension, add the top, then replace the wedges.

Ta-da! Now do it three more times. You made four, correct?

bookmark_borderMeasure and Mark

I’ve been working on a new large carpentry project, and it involves a bunch of joinery that for some reason I have decided to cut by hand. Everything needs to be measured out and marked, regardless of hand or machine cut, since I almost never trust jigs or templates for this kind of thing. Here’s the kit of measuring and marking tools I have assembled for this particular project.

Tools

So yes, there are three adjustable squares here, so that I don’t have to keep setting and re-setting them for the different lengths I need. The tool right in the middle is called a wheel gauge. You set the length you want, run the large brass bit against the edge of the board, and the little metal wheel at the end cuts a groove in the wood. I do have a Japanese kebiki gauge, but I have a difficult time getting accurate distances with it. The larger aluminum tool next to the wheel gauge is a modern Japanese marking square that is awesome because the large sides let you mark around the corners of lumber, so it’s easier to get straight cuts on 2x4s and other similar pieces. The small metal ruler is very useful for drawing lines between marks, and inserting into small holes as a depth gauge. I mostly mark things out in pencil using the blue 2mm drafting lead holder. but the pocket knife in the upper left is helpful for cutting a groove to start saw cuts, particularly on rip cuts.

I sewed the Daimon Hitatare Sugata some time ago, and added some kotsuyu embellishments and munahimo some weeks ago, but only got around to taking new pictures recently.

While the scroll I based this outfit on does not show these cords, I feel they are necessary. I am guessing that the scroll does not show them because the warrior in the image was not rich enough to afford them.

bookmark_borderMid-Height Japanese Sawhorses

Some years ago, I made a pair of low Japanese sawhorses for my workshop. They’ve been great, and very useful (mostly for keeping lumber off the floor in the garage), but it was time to take the next step up. My rickety western sawhorses spend most of their time sitting outside in the rain and snow, so they are not in very good shape. A set of mid-height Japanese sawhorses would be nice to have, because they are designed to break down into pieces for transport and storage.

Sawhorses Four

These sawhorses are about 24 inches tall, 24 inches long, and 22 inches wide at the feet. This height is just short enough that I can put my knee on a board to hold it while sawing, but tall enough that I don’t need to worry about scraping my saw along the ground. All the joinery is mortise and tenon, and there is no metal hardware in anything.

They are made almost entirely from pine. Given their modest stature, I could cut all four horses from three 4×4’s, two 2×6’s, and one 2×4. This means that there is only about forty dollars of material in the whole set. The pegs that secure the feet to the legs and the wedges that secure the legs to the stretchers are made from some surplus walnut I had in the shop. It’s always best to make the fasteners from wood that’s harder than the wood it is securing, but maybe walnut was an extravagant choice.

I wanted to make these from cedar instead of pine, but it turns out that these days cedar is five times as expensive as pine. It used to be only twice as expensive as pine. My next big woodworking project is going to cost me $500 instead of $100 for the lumber alone. Gasp.

I cut all the pieces to length by hand, but I used the mortising machine to cut nearly all of the mortises, and the band saw to cut nearly all of the tenons. I smoothed the walnut fasteners with a hand plane, though. After completing all of the shaping and joining, it took me about three hours with the orbital sander to clean everything up and remove most of the saw marks.

When taken apart, I can fit all the pieces for three horses into a single large (27 gallon) storage tote. This means that in the winter I can put the horses away in the garden shed instead of having them sit outside like the old ones.

bookmark_borderTachi Kake

The tachi is a type of Japanese sword that is similar to a katana, but it is worn differently, has different fittings, and is usually used as a more of a formal/ceremonial sword compared to a warrior’s katana. I bought a small tachi as part of my mission to recreate a full bunkan sokutai.

When not in being worn or in storage, the tachi would have been displayed nearby the bearer in a vertical stand called a tachi kake. These are readily available to buy, both as new items and antiques, but of course I wanted to make one myself. I was able to settle on a design, and I still have an excess of surplus wood in the garage.

Tachi Kake Before Finishing

Here’s what it looks like after cutting and shaping, but before finishing. It’s a little easier to see the shapes of the pieces. This is all pine lumber. The upright and the bracket at the top are just 3/4″ thick cut from 1by. The brace at the bottom of the upright is 1/2″ thick pine I had around; most of the examples I see online are only 1/4″ thick. The base is cut from some surplus 2by, to keep it bottom-heavy when unoccupied. The brace is fitted in a slot that I cut all the way through the upright. Tenons at either end of the upright fit into through-mortises for ease of assembly and disassembly.

All told, this item is about 26 inches tall when fully assembled. The tapering curve on the upright piece is one of my favorite shapes ever. I did almost all of the cutting on the band saw, though, because it made things like this curve so much faster to make. I also used a router to bevel and round over all the edges on all the pieces to give it a softer look.

Tachi Kake After Finishing

Here it is after about a half-dozen coats of black-tinted polyurethane. This stuff makes a good affordable lacquer substitute, and it dries in hours instead of weeks. I sanded the finish between every couple coats, but it still needs some final polishing. I also want to add some embellishment like I did for the kyousoku arm rest, but that might not happen until autumn.

For a better sense of scale, here’s another picture of the tachi kake before finishing, with my ko-tachi in the stand like it is supposed to be:

bookmark_borderPrototype Scribal Box

When I was getting the Debatable Lands Woodworking Guild started, I polled the people who were attending planning meetings to see what projects we could work on as a group to produce things for the Barony. One of the ideas was to produce “portable desk” type scribal boxes that the Baron and Baroness could gift to scribes. It’s taken me some time to get around to it, but I was finally able to plan out what such a thing might look like, and use up some surplus wood from the garage to make a prototype.

Closed Scribal Box

This simple, hinged-lid box is made entirely from pine, and finished with amber shellac. The walls of the box are half-inch thick, and the larger surfaces are 3/8″ thick. both thicknesses are the result of planing down some 3/4″ lumber to remove severe cupping warpage. The top and bottom were made from some 1×12 shelving, so I was able to make the full width of the box from a single piece without resorting to plywood.

The work surface is 11 inches wide and about 12.75″ tall, a fine size to accommodate 8.5″x11″ or 9″x12″ paper with some room to spare. A slight slope should make work a little easier on the wrists.

I have no historical examples for this kind of box, I am merely imitating other scribal boxes I have seen in use around the SCA.

Open Scribal Box

The interior of the box is about 10 inches by 14 inches, able to hold supplies slightly larger than average to a depth of about 1 inch at the front and 3 inches at the back. It’s slightly less than that because I decided to add the two battens underneath the lid to support the thin wood during use and keep it from warping.

The box is assembled using modern wood glue and wire nails, and finished with three coats of amber shellac. I’m not sure why my shellac came out so streaky this time. It could be that the shellac needs more alcohol in the mix, or that it was very hot in the shop yesterday causing the finish to dry more quickly than it could even out.

Because I had suitable material on hand, shaping and assembly of the box took less than a day. I did some hand sawing, but a lot of the sawing was done on the band saw. Assembly was entirely by hand, even to the level of hammering in the nails by hand to avoid blowing out the thin wood sides with the nail gun.

bookmark_borderKanmuri-bako

About two years ago, when I was preparing to be elevated to the Order of the Laurel, I was searching everywhere to try to buy a Kanmuri. The Kanmuri (which translates as “crown”) is the correct piece of headgear to wear with the Bunkan Sokutai that was to be my elevation garb. I eventually found an antique store in Japan that was willing to sell me one, however, theirs was in Thailand and would need to ship directly from there. I wound up picking it up at the post office the day before we went up to Pennsic. Since then, it has lived in a cardboard box, which was not the best place for this antique hat. Finally, I was able to make a couple of boxes to store and protect the pieces of the kanmuri.

Closed

That’s what they look like closed. They’re just simple lidded boxes made from plywood and finished with shellac. I have a stack of smallish plywood scraps from the last 20 years of larger projects, so this project was also an opportunity to use up some of that.

Open

Here they are with the lids off, so you can see the kanmuri pieces nestled cozily inside. On the left is the “pillbox” portion with its upright and pin (All three pieces are attached on this kanmuri.), and on the right is the tail. There’s a lot of empty space inside the tail’s box, but I wanted the box to help maintain the proper shape of the tail, and I wasn’t up for trying to make a proper bentwood box.

Assembled

In case you’re unfamiliar with the kanmuri as an object, here’s what it looks like when all the pieces are assembled. The cord drapes over the pin and ties under your chin to keep the hat in place. You can see that this kanmuri is not in the best shape. I’ll embark on a restoration project eventually,

bookmark_borderEndai Stepstool

Long-time fans of my work my remember the nine endai benches (one, two, three through five, and six through nine) that I’ve made in the past. These are great, but they are 18 inches tall. As the endai is a half-step between the ground and the en of a Japanese dwelling, I wanted to make something that was a half-step between the ground and an endai. Even though there’s no Pennsic this year, I wanted to tackle this little project and get it off my list. I recently sorted through all of the surplus wood I have, so I knew I had enough lumber on hand to tackle this project without having to go and buy anything.

Endai Stepstool

It’s entirely red cedar, and much of a style with endai six through nine, but roughly half-scale. Instead of being 36″ long, 18″ deep, and 18″ tall; this one is 18″ long, 9″ deep, and 9″ tall. The legs are 2×2 instead of 4×4. It’s a mini-bench.

I’m a bit disappointed about the external fasteners on the legs. I wasn’t able to do the joinery I usually do on the legs, and there isn’t a lot of room inside the apron for screws. Even with four screws on the interior of each leg it was a still a little rickety, so I gave in and put some screws in from the outside.

I put a bit of boiled linseed oil on it, to enhance the color and keep the wood from drying out. I’m pretty happy with it.
