Mitered Dovetails a Success

Jul 23 2014


I haven’t put much time into this recently, but did put in a half hour here and there over the last few days. I got the rest of the mitered dovetails cut. Actually, I screwed one of them up completely, cutting straight through where I was supposed to cut at a 45 degree angle. So I had to replace that piece. Other than that, though, it all went really well. I daresay I might actually be getting good at dovetails. Mine are far from perfect still, but they’re all half decent and they go a lot faster than they used to. On a couple of these, I made the cuts, cleaned things up visually, and the joint went together without any further fussing. Still a few gaps though, but nothing you could drive a tiny vehicle through.





Next up came ploughing the groove for the bottom. Nothing I love more than using my Record 044 (as seen in the last part of this post). The whole reason for doing the mitered dovetails was to hide this groove. I have some 1/4″ maple to make a bottom panel. So I made a 1/4″ groove. That miter is 1/2″, which gives me 1/8″ on either side of the groove. After grooving all the sides, I put them all back together and all the grooves line up perfectly. I’ll make the bottom panel, and that will fit loosely in there.

I hadn’t actually used the 1/4″ cutter from my 044, so it was still in pretty rough, “vintage” shape. So I had to spend a bit of time polishing the back, making a new bevel and honing it. Really only 10-15 minutes though.



Note that from the outside of the box, you can’t see that groove at all, just the miters.




On the front face, I cut the top down by 1/2″. I’ll plough another groove on the two sides at least, for the top panel to slide into. I haven’t decided if I’ll groove the back as well. I’m leaning towards not grooving it though. The top will be 1/2″ thick, to be even with the top, so it will need a rabbet on the edge so it will fit in that 1/4″ groove.



So, next up, grooving the top, making the bottom panel and lid. All in all though, the mitered dovetails were way easier than I expected, which is great. I’ll probably do more boxes like this.

Attempting something new: Mitered Dovetails

Jul 12 2014

This has been on my mind for a while, so finally made the leap and started a new box. I’m designing this so it will fit 8 1/2″ x 11″ paper. Here are the four sides cut to length.



Next, I lay out the dovetails. These are a bit different than usual dovetails. There are two dovetails in the middle of the board and space for three pins, but at each corner, there is an extra half inch. That’s where the miter will be.




The cuts are made.




The pin recesses are cut out, but then those two corner pieces are cut to 45 degrees. This will be the miter.




The pins are cut on the other piece, and the corners there are also cut down 45 degrees.




Put these together, and you have a dovetail joint.




But from the top (and bottom), you have a much more attractive miter joint.




This is a pretty finicky joint to fit. I worked on trimming this for close to an hour and I still need to finesse the miters as they’re causing some gaps. I suppose I’m doing pretty well for my first time attempting this though.

Beyond simply being attractive, the main reason for a mitered dovetail joint is probably so that you can run a groove inside the bottom edge –  and maybe top edge too – to install a bottom and a lid. The bottom will fit into that bottom groove and the top will have a sliding lid, fitting into the top groove. If you run a groove with traditional dovetails, you either need to do a stopped groove, or have the groove pop out through the pins or tails, requiring that you plug it up. Here, the groove will be totally hidden within the miter.

This is also my first time doing dovetails in maple, a much harder wood than the poplar, pine and cedar that I’ve done them in before. But for the purpose of dovetails, hard is good. Much easier to get nice, crisp lines. The softer woods just crumble and tear and dent all too much.

Hopefully without too much more trimming, I can get this corner fitting close to perfectly. Then I have three more corners to do. Never said this was going to be a quick project.

I should mention that I’ve seen two ways of doing mitered dovetails. The other way, the final pins themselves are mitered. This is a bit more complex, requiring multiple angled cuts. I can’t quite wrap my head around it yet, so for the first on, I opted for this more simple technique – normal pins and tails, surrounded by a miter.

Lamp Base Complete

Jul 12 2014

Well, I finally got the rest of the glazing bars done. So the frame of the lamp is essentially complete.


IMG_20140707_232144 IMG_20140707_232155 IMG_20140707_232214


Next up I need to make the panels for the very top and bottom of each side The top panels will have three holes in them and the bottoms will have a shape cut in them. Here are the pieces for the top. The bottom ones will come out of the board underneath.




Here are the top pieces fit into place. They are thicker than the groove, so I needed to plane down the back on each end. That’s part of the plan, not a mistake.


IMG_20140708_225535 IMG_20140709_185652


And the holes drilled in the top. They’ll be cleaned up and sanded smooth eventually.




And the whole lamp base with all panels in place.




And the bottom panel in detail.




I still need to make the top, which shouldn’t be that big of a deal. I’ve ordered some glass which should be in this coming week. I’ll have to cut the glass to size, at which point I can glue the whole thing up, tweaking everything for perfect fit. Then plane and scrape everything smooth. Then attach the top. Then think about finishing. Oh, and put an actual lamp base in it and wire it up. Alternately, it could just hold a candle.

At any rate, still lots of work to do on this baby.

Lamp Details

Jul 05 2014

Thought I’d show a bit more detail on some of the lamp construction. These mortises for the glazing bars are tricky. Not only are they only 1/8″ wide, but they have to bisect the rim of that groove, like so:



Here’s one of the glazing bars showing the half tenon. That fits into the mortise and ideally that puts the front of the glazing bar even with the front surface of the lamp.



Here’s a glazing bar in place, from the back and from the front. Not perfect, but I’ll be planing everything smooth after glue up, so it should be fairly decent.

IMG_20140705_082723 IMG_20140705_082730


And here are those half lap joints. Cut out the back half of one piece and the front half of another. They go together just right. I did a pretty good job on these so far.

IMG_20140705_082755 IMG_20140705_082811


And here we are with two sides in place. Pretty happy with the progress so far. It’s taking me maybe 10-15 minutes to chop each mortise, and then maybe 45 minutes to do all the tenons plus the half lap. So all told, 1 1/2 to 2 hours per set of glazing bars. If I had nothing else to do today, I could wrap this part of the project today. Maybe this weekend. Still lots of work to go after the glazing bars though.

Lamp progress

Jul 04 2014

Been back to the lamp. Got some new white oak in to redo the piece I totally messed up. It’s not a perfect match. A bit lighter and smoother grained, but it’ll have to do. Got that last piece redone and all the mortises and tenons done and now I have the full frame of the lamp done.



I spent a bit of time tweaking all 16 of those joints to make sure everything went together as square as possible with no gaps. Here you can see that piece from the new wood, which is quite a bit lighter. I think I’m going to eventually fume this with ammonia to darken it up, so hopefully that will even things out… or not.



Next come the glazing bars. Panes of colored glass will go on each of these side, plus one pane on the top. Each of the sides will have a couple of cross pieces forming … a … cross… like cross pieces tend to do. Anyway, I cut those out and planed them down to exact dimensions. One long vertical piece and a shorter horizontal piece per side.



Here’s how they’ll be laid out on each side. Now you can see that cross I so lamely tried to describe seconds ago.



These will be mortise-and-tenoned into the larger bars. That’s some tricky joinery as those glazing bars are 1/4″ thick. I’ll cut half of that away on each end to make a 1/8″ one-sided tenon, that fits into a 1/8″ mortise. That mortise has to bisect that 1/4″ lip between the outside face and the groove for the glass. The mortise then continues a bit deeper though, past the bottom of that groove. Hard to describe and I should have taken more pictures, but the result is that the glazing bars are firmly seated in place, and flush with the front surface. Here’s the first vertical bar in place.


Now I need to cut the horizontal mortice and tenons the same way.



Now, you might notice that those two bars will intersect in the middle. Since they can’t occupy the same space, I need to cut away half of each, in what I think is called a half lap joint.  I’ll be cutting the back part of the vertical bar and the front part of the horizontal bar, so that the horizontal bar seems to go behind the vertical.

Here’s where I started getting sloppy again. I marked one side of the recess, then marked the other and chopped out half the material in between. But… on the piece on the left, I made the second mark in the wrong direction. Ugh. I was very careful to do the next piece in the correct direction, but then realized that I did both of these on the front face of the vertical bar. This notch should be on the back. So two pieces wasted.



So, made a couple extra vertical pieces and tried again. Got it right this time and then cut the recess correctly on the horizontal piece as well. Google was nice enough to put a stupid fancy border around this image and do some creative blurring. I’m too lazy to get the unedited one and upload it again.



So now I have three more faces to do like this. That’s 12 more mortices and tenons, 3 more half lap joints, and hopefully, zero more goofs.

Weekend project

Jun 22 2014

Hey, I think I’m starting to get good at this woodworking stuff. I banged together this box for my Record 044 plough plane in well under 48 hours. And I don’t think I spent any more than 1 1/2 hours on it at any one time.


I started on Friday night after work. I’d had a single cedar board hanging around. I bought it some months ago but never had a project in mind for it. I was itching to try some more dovetails, and my Record 044 is always just hanging out on the bench, threatening to fall off, so I did some quick measurements and started cutting some boards to length.


I’ve never worked with cedar before, and I was disheartened at first. The stuff was just crumbling away under my larger saws. It’s seriously almost the consistency of particle board. I thought I’d never be able to cut a decent dovetail in this stuff, but gave it a shot anyway. With my 16 tpi Veritas dovetail saw, it actually fared pretty well. I got one set of dovetails done before the family dragged me out for dinner to celebrate Kris’s graduation from elementary school.


Saturday morning I banged out another corner, then walked the dog. I had some other work to do during the day, editing some educational video, but sneaked downstairs a few times while stuff was rendering and got the other two corners done. None of the corners were perfect. Each had one or two gaps that would need filling. But given the material, I felt I did pretty well. While that was gluing up, I started gluing up some panels for the top and bottom. The wood I had was about two inches too narrow, so needed to do the glue up.


Went out and did some shopping, came back, fixed the gaps in the dovetails and cut and planed the top and bottom and put some roundovers on them. This morning I applied a single coat of tung oil, and this afternoon I picked up some hardware – a couple of cheap hinges, a hook to close it, and some draw pulls repurposed as side handles.


Just wrapped up the hardware installation, and called it done. It’s far from perfect, but it was a quickie, designed as a utilitarian shop box to hold an old tool, not a work of art. I’m really happy with it.

One thing I learned is that I’ll be in no hurry to use cedar again. Although it does smell lovely when you’re working with it, it’s like trying to do woodworking with Styrofoam. Not only does it crumble, break and chip out at the slightest provocation, it scratches and dents if you do much more than breathe on it. Huge plane tracks even on the lightest setting. In fact, the plane body itself would score the wood if you pressed down too hard. It was the first project I got to use a card scraper on. Although it didn’t make things perfect, the card scraper was the only way I would have been able to get a half decent surface on anything, so good timing on that. But even the card scraper caused problems. When I was scraping the end grain of the dovetails, any little bits of end grain that broke off would get dragged by the scraper, causing big scratches in the face of the box. Even just the manhandling I did on the box while installing the hardware put a few new dings and scratches in it. But that’s all fine. I figure with a few months in the shop, it’ll look like a 100 year old antique.

Next up, I think I’ll do a similar box, a bit smaller, for my most recent old tool purchase, a Stanley 71 router plane. It’s got a few extra parts and attachments that need somewhere they can all live together.

Restoring a Saw

Jun 16 2014

I needed a new tenon saw. I got one from eBay for $35. It’s a Disston back saw. 12″ blade, 12 teeth per inch. As near as I can tell, from the mid-40’s. Disston was one of the premiere saw makers from the late 1800’s through the 40’s. After that, the quality declined. Unfortunately, that seems to be a pattern followed by most classic tool companies. Anyway, I’m pretty sure this is a quality one.


Or at least, it was. The saw was a mess of contradictions. It was so rusted that it was almost a flat black across the entire blade. It was such a thick coating of decay that I almost thought someone had coated it with varnish or something. But the teeth were in great shape and the handle also looked good. The medallion stamped into etching on the side had almost totally worn away, indicating it had been used a lot, but not in a long time. My best guess is that someone owned it and used it and took very good care of it. And then, maybe that person retired or died, or sold it to someone else and it wound up sitting unused for decades. It was not abused, just abandoned. Then again, maybe it was just never used and the faded medallion etching was just due to it rusting away. (Realized after typing this that the “medallion” is the fancy round screw head on he handle, not the etching on the blade itself.)

I started by removing the handle and spraying some WD-40 on it, rubbing it in with some steel wool and letting it sit for a half hour. Scrubbed it a bit, sprayed some more, let it sit a while longer. But that wasn’t touching it in the least.



So, I got out the sandpaper. First some 120 grit, then 320. Not ideal for preservation, but the quickest way to get it into a usable state.


This generated a huge pile of rust powder, but in the end, it looked half decent. The goal wasn’t to get it shiny new, just workable. Put a light coat of oil on it to prevent further rust and later on I might give it a coat of wax for the same purpose, and to help it cut smoother.


As I said, the handle was in decent condition. It could have used some sanding and a coat of oil or varnish, but that would just be cosmetic. Just looking to get this thing functional at this point. I might go back and work on the handle some more later, but this is good for now.


Next up, sharpening. I put the saw in my Disston saw vise and sharpened all the teeth for a rip cut, with passive rake at the toe, moving towards a more aggressive rake a couple inches in.


Finally, used the saw set to … set the saw. This involves pushing every other tooth in the opposite direction. Actually, I think the set was half decent, but I ran through it just to make sure they were all uniform.


At this point, time to test it out. It cut fairly well on a rip, wouldn’t really cut at all cross grain. A 12 tpi rip saw with a progressive rake should crosscut half decently. So I went back in and gave it another round of sharpening. I figure the teeth may have looked good, but probably had as much rust on them as the rest of the blade. A single filing probably mostly just got through the rust. The second filing seems to have improved things a lot. I also removed some of the set with a couple of hammers. Now it rips perfectly and crosscuts decently.

Not bad for $35 and 2-3 hours of a Saturday afternoon. I now have a high quality vintage saw that will last me the rest of my life.

Time Out!

Jun 14 2014

Well, first major goof on this project. Was going along OK. I got the rest of the mortises cut on all the long pieces.


Then started doing the tenons on the cross pieces. Got one done, nearly perfectly. Started on the next one. Here’s what I did:


Not sure if you can see what’s going on there. The tenon is supposed to be just about where that groove is. The piece is an inch thick, so I needed to cut a quarter inch up from the bottom of the piece as seen in the picture, up to where the groove starts. And cut about 1/2″ down from the top, to just above the groove. I got it backwards and cut 1/2″ up from the bottom – right through where the tenon is supposed to be. Basically cut the tenon right off before it existed. There’s no really good way of fixing this that I can think of. The tenon is already cut correctly on the other end of this piece. Otherwise I *might* think about filling the groove, flipping it over and putting the tenon on the other edge. But no. And I have no extra wood at all to replace this piece. I don’t even have two pieces that I can glue together to make the correct size in both dimensions.

So, I’ve gone and ordered another hunk of white oak. I guess I’ll have plenty to spare now. Hopefully the piece I’m getting is a decent match. From what I could tell in the pictures I saw, it seemed to have similar color, grain and flakes. I guess we’ll see. But this project will be on hold for a bit until that arrives. Actually, I have eight more tenons to cut, and can probably do some of the other work after that, so I may not be waiting around that much anyway.

Mortises and Tenonses

Jun 12 2014

Time for something new. A mortise and tenon joint. Or sixteen. A mortise and tenon is one of the key types of wood joints. A mortise is a hole in one piece of wood, and a tenon is usually a cut down part of another piece of wood. The the cut down part goes in the hole and form a very strong joint.

I start by laying out where the mortises will be. These will be partially inside the grooves I cut in the long pieces. The tenons will be on the shorter pieces.


These are chopped into the wood with a chisel. They are 1/4″ wide. My first time chopping mortises, but it went pretty well.



There are four mortises in each upright piece. Two near the top and two near the bottom. Because they are at right angles to each other, they actually meet inside.



Then, onto the tenons. First layout, then cut.



The tenons went generally pretty well, but my marking gauge must have slipped a bit and the first one I cut was a bit off, causing that cross piece to stick out rather far from the front face. I fixed it by gluing a thin strip of wood to the front of the tenon, and paring a bit off the back. Now it fits perfectly.

The tenons go into the mortises…


And the tenons on the other side go into the other mortises, and voila! We have a frame!



So, eight more mortises to cut, and twelve more tenons, and I’ll have a three-dimensional frame.

Actually, there was another goof I realized today. In looking over the plans, I realized that I’d cut the upright posts 1/16″ too thick and wide. I could have made it work that way, but after examining it in depth, I decided it would be possible to plane that extra bit out and get it to the correct size. I did it on the faces that have the grooves, which meant I had to re-plough the grooves as well to get them back down to the correct depth. But hey, another excuse to use my Record 044! Why not? Anyway, that went just fine and now all my pieces are perfect.

By the way, this is not some design I’ve come up with on my own. It’s part of a course called the WoodWorking Masterclasses, taught by Paul Sellers. If you’re at all interested in learning hand tool woodworking, Paul is a great teacher. I learned so much from his blog and free Youtube videos, that I signed up for the free Masterclass series and that was good enough to make me sign up for the paid membership. The current project in the class is this craftsman-style lamp.


That’s what I’m building. There’s already 2.5 – 3 hours of video covering this project. And I imagine there will be another 2 – 3 hours before it’s done. It’s really in-depth. Just what I need. Actually everything I’ve done here so far is just what’s covered in the first video.

Anyway, with my schedule these days, I don’t imagine I’ll get through the rest of these M&Ts until the end of the weekend. But that’s cool. I slip down into my man cave, plug in an audiobook and hack away at some wood for an hour or two here and there. Great stress reliever.

More cutting, planing, grooving

Jun 09 2014

Some of my other cut wood did warp a bit, as you can see in this picture.


Mostly just the 1/4″ pieces, and it’s not too bad. Once I cut these down to size, it will be far less of a bend on each piece and I left enough extra thickness so I can plane them flat with no problem.

But next up is eight more thick pieces. Cut these to length and went about planing the hell out of them.


The process is basically to flatten one surface. That becomes your reference surface. Then you flatten an adjacent edge, making it exactly 90 degrees to the first one. Now you have two flat, square sides. Then you use a marking gauge to mark a line to the exact width you want that piece and plane down to that line, cutting first if need be. Then the same thing on the final side. Now you have four flat sides that are completely square. Double check your length and squareness of the ends and you’re golden. These pieces are all about 1/4″ too thick but only about 1/16″ extra in width. So lots of shavings from the 1/4″ side.



These all get a single groove too.



Power tool users would use a table saw or a router to cut grooves like that. But I’ll tell you, using that plough plane is the coolest thing in the world. I’m actually sad that the grooves are all done for this project. It’s so fun to use that thing.

As a preview of where this is going, these pieces will fit with the original grooved pieces like so:




As you can see, the grooves match up, and two long pieces and two of the short ones form a frame with the groove all around the inside. And no, they’re not supposed to be the same width. That’s not a mistake.

Next up, I’ll be cutting some mortise and tenon joints to put all those together. Fun!
