Time to finish

Small delay getting to the shed on Sunday.

Well. It’s a kind of woodwork.

Anyway, that evening, at around -3C in the evening. off to the shed. There were feet to shape.

I know, I know, Richard Maguire does it with a chisel. He also has enough room in his workshop to stand at either end of this bench. Anyway, the fretsaw was in need of exercise. So once the curve was cut, I used the spokeshave and a paring chisel to clean it up and cut a chamfer around the feet.

Dainty.

And they don’t rock, happily. And I’d put in a bullnose profile on the front sides using then #5 and #4 and a cabinet scraper.

Unfortunately, that meant it was time for the job I was putting off. Out with sid…

Also after:

If anyone ever asks if it hurts to cut yourself with a chisel, the honest answer is no, they’re so sharp you don’t notice you’ve done it till later. Slipping with the scrub plane and slamming your hand full force into the dull edge of a planed-square board with a metal plane behind it, now that hurts.

Still though. Pretty.

Okay, time to set it on fire.

No, seriously.

There. Nice and discreet.

Then back upright for the last time.

And one good stare later (and a few minutes cleaning up the stuff I spotted with the cabinet scraper), it was time for disassembly for the finish.

For the top, it’s pretty simple. I chose the grain for the top and planed it to look nice, so that just has to get shown off. It’s getting a few coats (probably three) of osmo:

Just ragging on and sanding back when dry with 600 grit paper (it’s resting on the four bolts in the inserts there, I haven’t figured out how to levitate wood yet).

Nice rich colour when it’s wet, we’ll see how it holds up when dry. Then flip over and apply the first coat to the top nice and carefully.

The legs are getting a slightly different treatment – they got sanded down with 240 grit to open the pores from the plane finish they had, and then painted with oak shaving tea (collect two handfuls of oak shavings off the floor, boil with some water in a saucepan and then simmer for ten-twenty minutes, put water and shavings in a jar when cool):

The idea is that the liquid is now very high in tannic acid without having to go on ebay and buy tannic acid crystals. Paint that on the oak and you raise the tannic acid levels and raise the grain at the same time. So on monday night, I sanded down the legs with 240 again as they had dried (not bad going given that the shed hit -5C overnight) until they felt dry and smooth again and then repeated the oak shaving tree routine. I’ll sand them down again tomorrow and reapply the oak tea for the third time but this time I’ll just let them dry for a half-hour or so until the wood is damp but not wet; and then I’ll apply the other half of the magic, a solution of vinegar that has dissolved steel wool over the last week. The iron and the tannic acid will react and ebonise the oak. The end result should look like this if it all works:

In the meantime, something arrived in the post…

New bearings to use as thrust bearings in the bandsaw with a larger blade size. Gotta love the lego-parts aspect of mechanical engineering…

Standing upright

Last few days have been the first really cold ones of the year. -2C to -3C in the shed. And work was… somewhat excessive in the last few days so tonight was the first time in the shed in a few days and a to-do list was waiting. So…

Ran a slightly larger drillbit through the aprons to give some flex room for the bolts, and flattened the top of the aprons (I also spent a half-hour before this with the scrub plane and #5 flattening the underneath of the tabletop and hand-cutting the panel to width to trim out the worst of the bandsaw wobble).

The stainless steel inserts arrived on Thursday in the post, thankfully. Seems everyone makes these in zinc-plated steel, but actual stainless is a bit hard to find.

Bit of faffing about getting the legs centered on the tabletop, then putting in the drill bit and thwacking it to mark the drilling point with the drill bit (it’s a brad boint bit).

And now it’s time to drill the holes for the inserts. Look closely enough and you can see the marked point.

El cheapo drill bit depth stop so I don’t drill through the table. I have a fancy one for auger bits, but for drill bits, it’s blue tape time. What could possibly go wrong?

Oh. Right. Well, at least I noticed the shavings were shoving the tape backwards before I chased it right through the table.

Who says calipers aren’t good for woodworking? Check length of insert with calipers, get automatic depth gauge setting on the other, stabby end of the calipers. So I drilled the rest of the insert holes, stopping to poke the stabby bit in the hole until I had my depth.

Then it was time to realise that Richard Maguire had gotten inserts that you put a hex key directly into in order to drive home, but these sodding things need a bolt put into them and you drive them home with that. And since they’re going into a blind hole, the bolt has to be shorter than the insert. I managed to find some short M6 bolts (they came with the Triton sander as the bolts to bolt it down to the table with but I had my own), but they were too long. So. Time to break out my metalworking setup 😀

This is my metalworking setup. It’s a Record Imp, which I got back in February. It’s a nice lightweight metalworking vice designed to be clamped to a bench by people who didn’t need a full-size machinist’s vice. And it has nice features – you can bend pipe with it, you have a small anvil at the back and a striking surface (that small round thing just behind the jaws) and so on. Plus, it’s old – it’s a later model so this wasn’t made in the 1930s but it would have been somewhere between the 1960s and early 1980s, before Record went downhill. This is a small vice, but it is not a toy vice. I’ve screwed and clamped it down to a scrap piece of inch-thick oak, which then gets holdfasted to the bench.

So I clamp the bolt in the vice, mark off the length I want, remove the insert from the bolt, then fire up the dremel with a cutting disk (it’s a 6mm bolt lads, if I fired up the angle grinder it’d be like firing a sandblaster at sponge cake) and nip it off.

And now, just because we can, out comes the file and the tap-and-die set…

File off the sharp bits left by the dremel, recut the start of the thread after the file’s mangled it. Then thread the bolt into the insert and get out the socket driver.

Now, pick up that 14mm long insert, in a shed where it’s around 6-7C, slip with your fingers and drop it down behind the bench into the sawdust and shavings.

Swear profusely.

Get out the magnetic-head telescopic torch thing…

Right. Enough faffing. Paste wax to the threads and drive it on home.

Nice. Now we just do that with the other three…

Why is it spinning so easily on insert #2?

Ah, shite.

Apparently my bolts are made of particularly firm cheddar.

Mole grips to unscrew the insert, pointy thing to screw the bit of the bolt still stuck in there out the back of the insert (glad I didn’t get the blind inserts now).

Okay. Prep another bolt. Repeat all the steps above. Keep going, but be more careful this time.

Shite! At least I felt it go this time and stopped fast enough to be able to unscrew it in one part. Prep another bolt…

Felt this one going before it snapped. Definitely cheddar.

At least all four are in now. I might come back if I can find a non-cheese bolt and drive them below the surface later. For tonight, that’ll do.

Bolts in, and they fit (they’re a bit less than drop-in, but wood moves, blah, blah, blah, that’s my excuse and I’m sticking with it.

That’s a pleasant sight 🙂

Out with the MDF board at this point for a flat surface and check the rock – the front left leg there is about a millimetre out. Plus the feet are all at 12 degrees to the ground because geometry, so I mark off a flat on each leg, disassemble the table and even the legs up. And I leave it there for the evening. I’ve been up since… well, I was in work till around 0400 this morning after getting called around 2330 on friday, and I was back at work just before 0900 until 1730. On-call sucks sometimes. Oh well. There are worse complaints.

I have to shape the feet and thin the table edge and do the final smoothing of the tabletop and legs (cabinet scraper time!), all of which are finesse tasks so I’ll leave them for tomorrow, and I can be starting the finishing by tomorrow evening which is a good timetable for this.

Oh, and I also have a custom scratch stock profile to file. I’d rather do this with a hollow plane, but I don’t have hollows and rounds and I know (a) how much a set costs and (b) how much space one takes up 😀 So that’s not happening for a while. Hell, that was why I got the #050C combo plane, but alas I didn’t get the special doo-dads to let it act as a hollow or round 🙁  I’ve got an eye open, but the problem with the combiplanes is that they came with a lot of bits and doodads, and that was in 1930. You can’t keep both socks together for more than six months before you’re suddenly looking at lefty pining for righty who is has returned to the fjords; what odds that someone will have all 53 pieces from the original combiplane box that they bought in 1933?

So obviously, I just need to get a set of hollows and rounds.

looks up prices

passes out

Holy crap. I could buy two cars (second-hand) for the price of a set. Sod that. I wouldn’t have the room to put them anywhere anyway and the larger ones are all for things I don’t have the physical space in the shed to build.

But on ebay, unmatched planes (“harlequins” apparently, in a rare example of nice naming) are way less expensive – you can pick them up for a pound apiece in some cases. So I’ll probably wind up buying one or six hollows/rounds/beading wooden planes over the next year. You don’t need all that many for the kind of stuff I do. I might start with one that matches the profile above, which is drawn to match one of my gouges to do some decorative carving work.

I guess I’ll just have to try my “build something and sell it to pay for the wood” plan this year to let me do that 😀

Resawing sucks.

Honestly, if there is a better argument out there for buying a large bandsaw I haven’t heard it yet.

Yes, I’ve heard of roubo frame saws. My shed hasn’t enough room between the face vice and the wall to use one.

Yes, I have western hand saws. I either need to resharpen them or recut their teeth because the best one I have didn’t want to cut.

Yes I have a bandsaw already – it can’t resaw anything over 75mm. That there is 115mm.

So, wax blade, yank handle, shove handle, repeat till ticked off enough to pull board halves apart by brute force, plane off worst of the gack in the middle with scrub plane, give outside a few passes to mitigate uneven drying, repeat.

What, you thought there was an art to this? No, it’s just donkey work. And if you get too ticked off and pull the board apart too early…

It rewards you with a great big divot out of one end. Well, at least I don’t need the full length of any of these boards.

Left them standing upright to dry and warp overnight.

At least I got both boards resawn. That was more than I had expected to do.

So I had a play with my Lee Valley scratch stock and a gouge. I was watching some old Peter Follansbee videos and saw what I thought would make a nice decorative element on the rails of the chest. This kind of stuff shows up on the 17th century oak furniture he specialises in and was very common in the period, and since this is basically a 17th century design tarted up a bit, it seems appropriate.

Plus it’s pretty fast and simple to do, though I do need to experiment a bit more – I really need a round or beading plane or a custom scratch stock to form the surface in the middle before cutting the segments out. This took all of five minutes or so to do by the way – it really is fast when you know how (scratch stock bead line with a fence, chop at right angles with a gouge at regular intervals on that bead line, scratch stock bead line on the other side of the chops, then carve one scoop from gouge chop to gouge chop with the same gouge). How to actually end it when the rails hit the stiles is the main problem. I’m not sure how to continue it around the stiles/posts you see. I mean, I could try freehanding it but that seems wrong somehow unless I can get the rails and stiles utterly flush.

And the threaded inserts didn’t arrive today. Bother.

Tomorrow I’ll square up the stock and try to get the panels cleaned up a bit more and do something about that lid. I’d like it to have a small curve to it if I could, but the only way I can think to do that involves taking an inch-thick board and carving it with planes. And I don’t know about that – it’d be heavy and I’d have no way to prevent it warping with movement, which a frame-and-panel lid would address. I mean, according to the bible, it’ll move by 2.8% tangentially over the 30% humidity change between a summer and winter indoors around here (gotta love central heating), that’s almost a full centimeter of movement across the width of the lid. Make that from a solid block of wood and you won’t have a lid for half the year.

What’s the bible? Fresh from abebooks.co.uk:

Basically, a few hundred species of tree, with notes on things like general working properties and data like how much it moves when seasoning and when doing a 30% humidity swing and what its density and tensile strength is and so on, all done by a UK government office back in the days when this was what governments did. Yeah, it’s 1956/7, but tree species don’t change that much that fast (other than going extinct).

Bloody useful books.
