Off the shelf…

So fathers day was coming up and dad’s just finished the first year of a law course so lots of desk time and books involved. And then I noticed this on accidental woodworker:

Well, a desktop shelf that’d fit in the corner and leave room to hide pens and such underneath should be about right, and I had a nice piece of sapele…

…yeah, no. Turns out sapele is a total pain to plane with a normal handplane because of interlocking grain. By the time I’d resawn it from 6/4 down to just under 3/4inch thick and then flattened the resulting planks I’m down to just a shade over a half-inch thick and that just doesn’t look right for a shelf. So I abandoned the sapele to future box-making duties, and ordered a toothed plane iron to deal with the remaining sapele in my store.

And a new lighter mallet for finer work (the lignum vitae mallet is great but was a bit heavy for working on things like half-blind dovetails).

And then I hauled out one of the last planks of walnut I had to hand, skimmed it and rough-cut it from 9×48 to 9×23 and 8×24, losing an inch of length to kerf and clipping off a rough end on the board and losing an inch of width to a bit of live edge on one half of the board. I also grabbed some oak I had and crosscut it in half, then laminated the two halves together to one 3×3 block; and then cut a diagonal line across the width of the board to give me the two feet – the thing you stand on, not the archaic unit of measurement – roughly 3×2 at the front and 3×1 at the back for a nice gentle slope so that the spines of the books are visible when sitting or standing at the desk.

Then on to the sides. I took the 8×24, cut that in half after I had it flattened and thicknessed down to about ¾”, marked off which corners I’d cut off for that sloped look and then marked out both for a stopped dado for the shelf (which would act as a sort-of-half-lap joint as the shelf would have two shallow rebates on either end to fit). I was planning on using the cut nails I got from Dictum a while back as a design feature so I didn’t make it a sliding dovetail, the nails would hold well enough.

I cut down the walls of the dado as much as I could with the saw and then cut out the waste and the rest of the dado with a chisel, and used a router plane to tidy it all up.

Didn’t turn out too shabbily.


Even got some nice grain alignment between the sapwood and the front of the uprights.

Next though, have to attach the feet to the uprights. Ralph used biscuits for his, but I don’t have a biscuit joiner (or room to use one or store one) so I just cut mortice and tenon joints, complicated slightly by the joint being sloped – the mortice is deeper at one end than the other and the tenon is trimmed as well to avoid chopping through the feet when making the mortice. This gives even more rake to the uprights – it’s not a huge amount, but it does give that slightly steeper angle without needing either the joint or the angle of the feet to take the full angle. It’s a little nicer and it means the spines of the books are at an angle that makes reading the titles easier if you’re sitting or standing at the desk (Dad’s desk is one of those electric standing/sitting desk things).

Not as hard to cut as the curved tenons in the cot a while back. And I did think of using my new morticing chisels but the one in the size I wanted to use has a handle that is literally falling off, and it weighs two pounds and looks like a railway spike. It’s more for deep morticing through a few inches of oak. For a blind mortice like this that’s barely an inch at the most, the firmer chisels are the better choice. Also, holdfasts. Best morticing workholding ever.

And with those fitted, time to sort the back rails, also from some oak I had.
They’re a bit thin, but that’s okay, this is for a desktop so “brick shithouse” isn’t really the design aesthetic I’m looking for here. I was thinking of doing mortice and wedged tenons here, but the walnut was a bit narrower than the sapele board I started with (so pushing the rails back means being able to hold wider books), and walnut’s far easier to carve, so I switched to the idea of using half-blind dovetails so the sides were kept fairly clean-looking. Those went very smoothly (it’s walnut, you’re basically cheating using it for dovetails), the only difficult part being the layout (because you basically need the whole thing assembled to get the final shoulder lines for the last two joints). But you’re only cutting four dovetails in total so it’s fast work.

With that done, that was the last of the joinery, and all that was left was shaping, small touches and fettling and finishing. I took the front corners off with the small ryoba and planed them ganged together to keep the sides matching, then took a small gouge and did some end-grain detail stolen again from Brian Halcombe:

Getting a little better, but still nowhere good as his are. I think I need to practice sharpening my gouges more 😀

I also took the fretsaw and my new preston spokeshave to the shelf to do some shaping work on the two ends (and got out the gouges here as well for the little bit of remaining endgrain). The shelf is a bit thick to avoid (a) sagging in the middle from the 60kg design weight (books weigh more than most people think, the standard loading is about 30kg/ft or so); and (b) thicknessing the board down too much because it turned out one side had the corner of a horrible knot in it and it was a complete pita to plane. But by planing a slope into the underside of the shelf in the last inch or two before you see it, it looks a lot thinner at first glance than it actually is – neat trick learnt from Richard Maguire’s end table videos.

You’ll notice I’ve also drilled pilot holes for the cut nails here. I bought a few boxes of those from Dictum a while back and haven’t had a chance to use them yet. They look quite nice:

For those who don’t see what the fuss is about and haven’t spent sixty hours listening to Christopher Schwarz, Roy Underhill and every youtuber with a table saw ranting about these things, they’re what nails used to look like for thousands of years until someone invented the cut wire nail a hundred years or so ago and found he could make nails that were objectively worse than the existing product in every single way and yet still be successful, so long as they were cheap. The race to the bottom is a very, very old game…

Anyway, these things look decorative and hold things together much more securely than the round nails we use today, but more than that, when the wood swells or shrinks and moves with the seasons, the nails flex with the wood which screws can’t do. This stuff lasts so long they’re still finding shipwrecks from the roman empire where the nails are holding them together.

Anyway, that’s my story about why it was okay to pay six quid for a hundred nails and I’m sticking to it 😛

And then I knocked the arises off the other edges with the preston spokeshave (that thing is rapidly taking over as my favorite tool), and with that done and everything suitably handleable (and the front of the feet turned from blocks to a less aggressive shape), it was time to do the final fitting and fettling of joints. 

It was fairly painless this time. That shelf doesn’t rock or tilt 🙂 I’m a bit pleased by that, the layout was a bit hard because the wood’s not perfectly flattened (that stupid knot on the underside looks pretty but was a pain to work). And then final finish planing before the shellac. At which point I made the happy discovery that not only do we get some lovely colour to the walnut and some lovely medullary rays in the oak, but the walnut is also lightly figured. Which was a nice unexpected surprise, but is unfortunately most prevalent on the underside. Doh.

Well, only one last thing to do before applying finish…

Fire! 😀

Turns out, a real blowtorch versus a chef’s blowtorch isn’t even a contest. A chef’s blowtorch will do creme brulee, whereas one of these weapons of mass destruction will just burn through the sugar, the creme, the dish and most of the table. They’re excellent 😀

I did nearly burn the wood though. Mental note; branding irons only need to be that hot for flesh, for wood you want them less hot. Had to take the block plane to the endgrain to clean it up a little in the end. But that was that, and now on to the shellac. First a quick test…

And we’ll go with garnet for the walnut and lemon for the oak, with maybe a last coat of blonde? Brush on the first coat, then wipe on the next three, knocking back with 0000 steel wool in between each coat.

See what I mean about that walnut? Shame that’s the underside really.
And after a few days (I just did a coat every evening after I got home):

And then it was time for assembly and glue-up. That was a lot more straightforward than I expected too because the nails effectively acted as clamps. So out with the hide glue and I didn’t even need the hot water this time to warm it because today was around 26C in the shed, the warmest day of the year so far. Glue into the stopped dados, then seat the shelf in the dado and knock it firmly home with the deadblow hammer, then drive the three nails to within 2-3mm of being fully seated; turn it over and do the other upright. Then glue in the back rails because the uprights slope inward slightly and the tension holds everything in place. Drive home the nails fully, glue the mortice and tenon joint for the feet together, stand it up and clamp the lower back rails (the upper rails couldn’t be clamped because of the slope on the far side of the upright at their level, doh. Maybe I should have drilled the dovetails for smaller decorative nails, it’s certainly a historical thing to do that).

Left everything to cure for a few hours, then painted the bottom of the feet with titebond over the shellac, and sat them down onto some nice green felt (don’t want to scratch the desk) and let that set up for a few hours before trimming off the excess with a sharp knife. And that was it, all done.

The brand looks nice actually. I was afraid it’d be a bit out of place, but it seems to blend in discretely.

Kicking myself that that figure is on the underneath of the shelf…

But those nails do just look the part, don’t they?

Obviously I need to buy more Lost Art Press books 😀

And yup, there’s the original sketches and notes as well. Not an Ikea design 😀

Thanks again to Ralph at the Accidental Woodworker blog for the idea, it worked out pretty well.

Wristrest

So I’m still cleaning down the shed from the cot (finally got all the shavings under control…) but yesterday an officemate (hi Gary!) was looking at MassDrop (think “what to get for the rich geek who has everything” with a pricetag to match) and specifically at a wrist rest. For those who don’t type all day, it’s something to rest the wrist on while typing:

If you type all day every day like a lot of software engineers do, this is a pretty necessary thing or you wind up with carpal tunnel syndrome. I’ve had that, it’s not fun (it’s why I’ve used kinesis ergonomic keyboards for twenty years).

So the specific one Gary was looking at was wooden, and nice enough if a bit simple:

I mean, it’s not some gel-filled cushion, it’s not articulated, it’s just a shaped plank of wood. Walnut maybe? Fourteen inches wide (the width of a MacBook Pro) and about three inches deep.

They’re charging $95 for it (or they were, it’s not for sale any longer). I nearly choked on my coffee. I told him that was insane, that it was a lump of wood and not worth it and that I could knock that up in my shed in twenty minutes from an offcut. So he said “prove it”.

That’s how I keep getting myself into these things. You’d think I’d have learned by now.

So I go home, I find a piece of walnut offcut (in this case it was a length intended to be part of the cot frame but a bad rip cut and a waney edge made it unusable for that), I cut out a 14″x3″ piece from it (I don’t even take the time to lay it out) and skim plane it to clean off the rough-cut furriness. Then I plane one face and edge to square, and shoot the ends square from that. I don’t bother with the other edge or face because they’re going to get shaped anyway. And I cut the corners curved on the front using my new toy that just arrived from Dictum today:

Well, I have a project or ten in mind that will involve dovetails and I want to try sawing out the waste on the pinboard instead of chopping it out because that took a bit longer than I thought it would on the cot drawer. I need a better place for it to live though…

I also need to finish tidying up, and one of the next shed projects is tool storage. But for now…

And from there, I get out the spokeshave and round over edges and I use the jack plane to cut a quick chamfer on the front edge and then go over everything with the spokeshave again to get it all nice and smooth, and I hit the ends with some sandpaper for a few seconds to get the last little bits around that knot on the left front side.

Total time from start to here was about 25 minutes or so (I was faffing about a bit with the new fretsaw). With machines, that’s two tablesaw cuts, two mitre saw cuts and a run-around on a router table, so maybe three minutes?

It needed a little finish and I had the dregs at the bottom of the shellac jar to hand so…

One coat on by brush, then in for a cup of tea and a bit of Richard Maguire’s latest sharpening video while it dried. Then out to the shed again, some steel wool to knock back the first coat of shellac and rag on a second. Back to the house for more tea and Maguire, and half an hour later I take the offcut piece of felt I had from lining the cot drawer and cut a small piece out of that and spread it and the underside of the rest with contact cement from the end of a tube left over from putting leather on the bench vice jaws.

Let that get tacky for ten minutes, then press the two together and trim the excess. And then a final coat of briwax on top for the shiny.

By this point I realise I’m foostering so I draw a line under it and wander back in from the shed. Total work time is about 30-35 minutes (with something like 90 minutes of waiting on finishes while watching videos and drinking tea in there too). And the test fit worked:

And it doesn’t just work on my laptop, it works in production*:

So $95 versus €2. Hell of an exchange rate, even when you count the three minutes it’d take to make with machines, labour, marketing and so on.

 

*That’s a joke for the other IT people btw.

Foostering

Right, I just need one or two hours of calm dry weather and…

*sigh* Feck’s sakes. Fine.

But at least I can put in the glue blocks to support the top panel. Yesterday I trued up a corner of a stick of walnut I had as an offcut from the drawer front and then cut it into four ~10cm lengths. Granted, this isn’t traditional, glue blocks are traditionally whatever cheap softwood was lying around, but I had this as an offcut so why not.

Then today I had a few minutes of trying to figure out how to clamp them in place because I didn’t know how this was done traditionally. One quick internet search later and yup, you just paint the glue face with glue (hide glue is traditional but apparently any wood glue works), rub it on the spot where you want the glue block to stick to ensure both sides have glue and there’s no air in the glue joint, then hold it in place for a few seconds and there it sticks.

Don’t give it a knock until the glue cures, and there you go, glue blocks.

But eventually there were two or three dry hours in the late afternoon, so I moved the cot outside for the last time and started fettling the drawer. Which it turns out was necessary – when I was assembling it yesterday I had to stop half-way through glue-up to shave down the width of the plywood base, but obviously I didn’t shave enough and it had pushed out the sides of the drawer at the base by a few mm, so now I had to shave back the outside with planes in order to fettle it.

But eventually I got it to fit smoothly, and I’d cleaned up the glue and joints as well. Then it was a case of pushing it in flush, finding it was hanging up on the drawer rails, trimming them to give a rounded ramp type profile at the start so the drawer would go flush, then marking off its position on the rails with a pencil, and gluing a stop block in place on the rails with a cushioning pad. I clamped those in place for a half-hour or so just to be sure, then took off the clamps and glued the rails in place. That was the last bit of construction on the crib.

Yay!

Well, okay, I have to screw on the drawer pull, but I’m not counting that because.

I SAID BECAUSE.

And then it was time to finish the drawer, and I’m just going to go with shellac. I had thought of using milk paint and osmo over the top of that, but the more I thought of it, the less I liked the idea of a red drawer, even though it would have been funny. So just shellac.

And that’s the last of my shellac as well, so the whole drawer got three coats (sanding back after coat #2), and the front gets a final fourth coat.

Dovetail money shot, right there.

And in the meantime the cot got moved into the kitchen.

…and the thing rocks. The torsion the mis-bent steambent upright put on the frame torqued it out of square by about 3mm over the length of the piece, but the MDF assembly platform had gotten wet and had smushed enough to hide that. Sod. So tomorrow (I have a day off), I’ll take the drawer, put the pull in place, maybe line it because the plywood’s a bit unpleasant looking, put that into the frame and mount the mattress platform and basically put it all together, see how bad the rocking is and trim the feet to stabilise it.

And that’ll be it. It’ll finally be done.

 

 

Shit, this thing won’t fit in the car, how the hell do I deliver it?

To-Do List:

  • Make a drawer
    • Maybe add runners underneath the drawer?
    • Finish drawer with shellac.
  • Glue the drawer supports into the frame.
  • Even more last minute fettling and foostering (panel support blocks, drawer stop blocks)
  • EVEN MORE last minute fettling (levelling the legs, screwing on the drawer pull, lining the drawer)
  • Close door of shed, lock it, walk away and never do another project with a deadline ever again.
