Sunbathing poplar

So asking on UKworkshop about that clamping problem I was thinking about with the shelf/desk project led to the conclusion that housing joints won’t work and tapered sliding dovetail joints are the better choice. That will probably mean some router work because of the precision needed – I could probably make a tapered dovetail joint that wouldn’t pull out, but one that would be precise enough to maintain the shelves against racking would be beyond me. So a new router bit, get that router table out of storage and actually assemble it (I basically picked it up in Lidl intending to use parts of it in a proper router table at some point and then just developed a dislike for routers in general πŸ˜€ ), and that sorts two of the shelves out; the third gets dovetailed into the top shelf which will also help with racking.

And I keep sketching the idea in my head to try to nail down the bits of it.

It does feel like I’m trying to squeeze the shape I want out of almost not enough wood; the 8″ wide poplar planks I have might not be wide enough and I might need to do a run to the timber yard for some 12″ wide boards. Which would mean a half-day off work and I’d wind up buying a lot more than one board because if you’re giving up vacation time, you buy in batches. So I’d rather get the pieces out of what I have, but if I can’t, there will be more walnut and poplar and maybe some utile to see what that’s like to work with… see, this is the problem with going to the timber yard πŸ˜€

Meanwhile, we’re in a heat wave here and the poplar I have has these green streaks, so I figure I’d let it sunbathe for a few days to get rid of them and get that lovely honey colour poplar gets…

Better than a shop dog πŸ˜€

The colour of the wood is easing but it’s not a one-day thing…

Before on the left, after on the right in both cases there (the badge is to get a white balance reference but even that didn’t help much, the direct sunlight just blows the camera away).

I’ll keep doing that for a few days, see if it helps.

I also took the opportunity to see what the side would look like with a 1:1 sketch.

(Yes, we’re reseeding that bit of the lawn, we’re just waiting for the weather to break next week or the seeds wouldn’t have a chance).

That bottom desk shelf really looks too low, I know, but I measured Junior’s knees when he was sitting down and nope, that’s the right height. Kids are justΒ small and the scale looks all wrong πŸ˜€

And today, since it was the middle of a heatwave, I had some hardware, tools and a chunk of a tree shipped to the office so I could carry them home…

These quadrant hinges are very definitely *not* brusso hinges πŸ˜€ But they will suffice to learn and experiment with. Plus, no damned nails, so hopefully less fiddly.

Nobody in the office could identify this πŸ˜€
It’s an electric heated bending iron, normally used for making violins. This one’s not temperature controlled, it’s just a PTC resistor in a metal housing that you plug into the mains. The fin bit heats up and then I can use that to bend stringing around sharper corners. Yeah, I could have used a hot air gun, but here’s the thing – in an 8×6 shed, any hot air (at 100C or so) that leaves the gun tends to hit something while still hot enough to damage stuff, especially with foam on the roof for soundproofing, so I decided to go buy this thing (hey, it cost a total of €37 delivered from China via the customs department) instead.

But.

There’s a rule I have for electric stuff you buy off aliexpress (or ebay). If it’s on batteries, it’s probably okay. But if it plugs into the mains, you take the thing apart and check it before it ever goes into a socket, so this got disassembled in the electronics lab and tested for shorts, for the case being connected to the live wire, all that sort of stuff. But no, it seems grand, so out to the shed…

I said itΒ looked grand, not that I trusted it yet πŸ˜€ More testing for voltages, waiting to see if the temperature stabilised properly and so forth (that bit of sapele there is to become the base it gets fastened to so I can holdfast it to the bench). All the electrical tests seem okay so far…

The temperature seems a little high mind you, but I think it was made for 110V rather than our 240V. More monitoring needed really and I might want to put some handles on that bit of wood because the fin is not very well isolated thermally from the base…

I worry about the temperature running away too far – if it melted insulation then the case might wind up live and that could be fun. I mean, there’s no ground in the shed really, it’s a wooden floor, but still. Not exactly ideal. Hence, add some handles to the base to pick the thing up and move it about. And maybe some wooden rails along side it to act as hand rests for when I need to steady my hands for particularly delicate bending work.

And what will it be bending? Well, I finally found a commercial source for thick veneersΒ (in this case, 1.4mm thick which is perfect for what I want it for – it’ll get a bit of handplane work to trim it to the thickness of the groove, but with one side of the strip being thinner so it wedges in there).

Some sycamore…

and to compare it against, some maple…

and just for fun, some cedar of lebanon…

That last one is seriously aromatic. I have got to find a source for actual boards of this to use as drawer bottoms, I now know exactly why they used to use this for that purpose. It’s a nice smell, but you know you’re not getting mothholes in your shirts if the drawer is made of this stuff.

Even the bit of hardboard they used to ship this stuff will be of use, if only for drawer bottom material and the like. Happy with that find, now I just have to wait for brexit to screw up the trade rules between here and the UK and for all this wood to become unavailable again. Hell, it might be an idea to stockpile, the way things look to be going…

(You laugh, but you know how house prices in Ireland are rising faster than a SpaceX launch? And you know how we use timber for building houses in everything from making doors and stairs to roof eaves, scaffolding and so on? That timber all comes from the UK because Irish timber yards are too small to buy on the continent because we’re just not that big a country – we have 4 million people, they have 50, and they build more so they buy wood by the hundreds of tons and we buy off their yards and ship it to here. Brexit is going to throw a huge spanner in that, stuff will either have to come from the continent meaning higher purchase prices, higher logistics cost and so on; or yards here will have to buy stuff from UK yards at enormously higher prices. And all that gets passed on to the final house price here. Stockpiling doesn’t seem so ridiculous now, does it, eh?)

Almost there…

So I was a bit sneaky this morning and went to the shed for ten minutes before heading off to work. I’d prepped the part for the end cap on the toolbox last night but because I’d clamped up the base I couldn’t glue it on without risking either it or the base shifting when clamping. So this morning I went out, took off the clamps from the base, made sure I had clean gluing surfaces and glued up the end cap and clamped it. And of course, as you’re in a hurry, everything gets irksome and fiddly.

Why on earth did it choose this morning to lose it’s head? πŸ˜€

But I got it clamped in the end.

Then off I went to work and later this evening…

Sawed the end cap flush with the flushcut saw, planed the base flush (with lots of chamfering to prevent spelching – not sure how you’d fix that at this stage) and then started cleaning up squeezeout.

Y’know, I thought those plastic razor blade things would be a total gimmick, but for stuff like this they’re actually quite useful. I did still have to do some careful chisel work but the bulk of the removal was very straightforward using this and the best part of the plastic blades is that you really have to abuse them to nick the piece so you don’t have to be quite so careful as you do with a chisel.

All nice and clean. I do still have to pass over the sides with a last smoothing plane pass and probably some sandpaper, but that’s for later.

Next up, glueing the first stop on the lid after trimming it carefully to length. I’ve shaped the inner edge of that stop so it’s a little less abrupt.

This is all going to make more sense when it’s done.

Also, I gave the inside of the box a quick swipe with some danish oil – it’ll be easier to do it now when I have access. The other end cap will go on tomorrow and after that it’ll be harder to not have any missed bits inside, so I’ve done the one inner coat I was planning on now. Should make it easier.

And done for the day. Material for the other endcap prepped in the background, but I still need to find material for the key – it and the lid will be distinctive and everything else will be beech or the walnut pegs. It doesn’t look too bad so far.

Speaking of finish, time to check how those purple stains dried…

Interesting. The neat stain is definitely too dark, as is the light purple over dark blue; and the lightest purple just looks like the wood’s grubby, but the higher concentration of the stain doesn’t look too bad. Needs to be even more concentrated but I think we have a good possible there. I won’t get back to the locker till next week though, but it gives the joinery and the wood for the door time to rest and move if they’re going to. And gives me time to think about decoration. What happens if you cut very white stringing into a stained wood I wonder…?

Pottering about

Last project finished, next one not properly started yet (just have the rough cuts done) and another in mind but not off the notepad yet. So now’s the time to work on the shed itself…

That’s the dust collection for the shed (it’s collapsed because the vacuum hose got clogged with shavings and the shop vac managed to pull enough air out of the barrel for atmospheric pressure to crush it). It’s a bit… big. For the shed at least. So a while back, I got a smaller drum.

And it’s been sitting there since I bought it, getting in the way, because I was trying to get other stuff done. So…

Out with the old…

And mark out and measure for the minicyclone seperator in the lid of the new drum, cut out the large hole with, of all things, the lie-nielsen radius cutter I was using for stringing on the last project, and then drill the holes for the attachment screw and fit it. In the end I didn’t use the sealer though, I’m not sure if it’s needed just yet.

It’s a wee bit smaller πŸ˜€
May need to re-jig how it’s held upright because unlike the older drum, this one has no side handles to thread with bungees.

Much smaller and neater. I didn’t use the sealer yet – I was mucking about with a safety valve to stop it getting crushed like its predecessor, but discovered that even with the 10mm hole in the lid wide open I was still getting suction on the main hose, and if I blocked that main hose, the 10mm hole wasn’t enough to stop the vacuum trying to collapse the drum. May need to rethink that a bit – it could just be that the smaller size results in far more rigidity and I don’t need it. Or I may need it later due to wear and tear. We’ll see.

Either way, more room!

And more clamps! There were a few 3″ clamps going for a fiver per pair on ebay so I grabbed them. They’re getting some PTFE lubricant here. At some point I really ought to take off the old paint and repaint all of these but I like the old record blue and I’m not sure I want to go into learning how to stove enamel stuff in the same oven we cook dinner in…

(Oh and the calculator is because I can’t multiply by 1.618 in my head)

And this is the next project after the next one; it’s not off the notepad yet but I was looking at how beech and walnut look beside the rippled sycamore that I want to use in it, trying to figure out colour contrasts so things look matched rather than looking garish, but also letting me keep mucking about with stringing.

I do have one shed task left though, and that’s to grind a camber in the new scrub plane blade. It won’t be anywhere near as severe as Sid’s camber, that was something like a 4″ camber, this will be about 7″ or so. I’ll get to that next, and then I’ll get back to the locker.
