A Welsh Stick Chair for the Apprentice – Reprise

IMG_4223

The completed chair in situ

Long time readers may remember the stick chair I was building for the Apprentice, based on a child-sized 18th century chair held in the collection at St Fagans. That build stalled last year when my first forays into steam bending a comb proved to be unsuccessful. I didn’t abandon the build, but it went on the back burner while I built a steam box, and then all of my workshop time was absorbed by the article for Mortise and Tenon, and the Roubo bench build. But I never stopped looking for an opportunity to finish this chair. While I was processing stock for my stick chair for the M&T article and some other projects, I found within one of those huge oab slabs, some curved grain which matched the curvature of the comb for the Apprentice’s chair. Jackpot – no need to steam bend stock (although with the steam box now complete, I am looking forward to steam bending chair parts in the near future). I cut the comb out of the slab, and set it aside while I finished ther chair for M&T.

Painting the chair

With the M&T chair (and article) complete, I managed to find some time to clean up the comb with spokeshaves, and did the final glue up for the Apprentice’s chair. The chair is made with oak from three different sources, and there is not enough consistency of colour across the various components to use a clear finish. So original my plan was to milk paint the chair green to match the green Chesterfield armchair I sit in. On reflection, I asked the Apprentice what colour she would like the chair, and we looked at some milk paint samples until she settled on Sweetheart Pink by Real Milk Paint. After quickly placing an order with Tools for Working Wood, we were ready to finish the chair.

Painted, burnished, and oiled

I thought it would be fun for the Apprentice and I to paint the chair together, and she eagerly assisted me with the first coat. Milk paint often takes several coats for a consistent finish, and I applied a further three coats in the evening. Once we had a good consistent finish I burnished the paint with brown paper, and then ragged on a single coat of Osmo Polyx. The Osmo deepened the colour of the paint a little, and also emphasised the texture of the underlying wood (particularly the facets on the legs and sticks). The comb had some striking grain, and so I deliverately left that unpainted to add some visual interest.

A satisfied customer

The chair now resides in our lounge, next to my reading chair, and the Apprentice seems to really love it. She is also facinated by the idea of making furniture, and so hopefully it won’t be too long before she joins me in the ‘shop.

Slab Life

IMG_2400

Two very large oak slabs, waiting to be turned into something useful

I’ve had two large oak slabs sitting in the corner of the workshop since January – the product of a fruitful research trip last autumn to Whitney Sawmills and St Fagans. The slabs are 50″ x 45″ and 2″ thick, and take up a monstrous amount of space, so I’ve been biding my time to cut them down into usable sizes and reclaim some much needed floor area. After several evenings of cutting mortises for the Roubo bench, I felt it was time for a couple of hours doing something different, and decided to breakdown the slabs. As I’m planning on doing a full dry-fit of the Roubo undercarriage soon, having some clear space in which to assemble the legs and stretchers will definitely make like easier.

Key tools for working with rough lumber – a timber framing square and pair of thick gloves

The first thing I do whenever I break down rough stock is work out how to efficiently harvest the parts I need, along with any useful spares. This was no different, although the size of the slabs did present a few different challenges. The oak was purchased for a special project I’ll be starting work on very soon (more about that soon), but I also knew that I’d have plenty of spare left over for other things. So, having marked out the critical components I needed for the main project, I reviewed what spare material I had.

_DPP8166

Tracing the outline of the seat for the settee – I did this on both slabs before deciding which would be best

As can be seen from the photos, the slabs are roughly “Y” shaped, from where the trunk had forked in two directions. The right-hand stem of one slab had been whispering suggestions of being turned into a two-seater Welsh stick chair. As a project, that really appeals particularly given the gentle concave curve to the edge of the slab which would work nicely as the front of the seat, and I can shape the rear edge to match. That focus on letting the material dictate the proportions and form of the chair is something which early Welsh stick chairs really emphasised. To make sure I had enough material available for the seat I rigged up a pair of trammel points to a long ruler, and traced along the edge of the slab to establish where the rear of the seat would fall.

IMG_2405

The Disston D8 and staked saw benches are how I cut up stock for ever project

The slabs were large and heavy enough to require rolling around the workshop instead of carrying. That being said, placing a slab on my pair of staked saw benches was rock solid while sawing. I ripped the settee parts off one slab, as well as the components for the main project off both slabs, using the Disston D8. The slab was still reasonably wet (24%) which meant that sawing it by hand was not as heavy going as it would have been if the timber was dry. The remaining sections were then crosscut to size, and stickered to dry out a little more before I bring them into the house.

When the callipers slip over the middle of the tenon, you know you’re done.

The final piece of the puzzle for the Surprise Chair is the leg profile. I want this to add another texture and set of lines to contrast with the seat of the chair. For the Apprentice’s Stick Chair I used irregular facets and a hand-rounded process with the scrub plane and block planes. In the spirit of my last post, for this chair I wanted something different. As the maple takes crisp details really well I decided that a tapered octagon would work very nicely for the child-sized proportions. It’s also been a couple of weeks since I octagonalised anything, which in all honesty is far too long.

_DPP6841

Tapering the square leg blank

As a first step I trimmed the leg blanks to length, allowing 10 1/2″length for the leg, and 2″ for the tenon. Previously when turning tenons at the lathe I’ve used the Easy Rougher tool for the whole job. This approach has been effective as bringing the tenons down to size, but it can take a while to hog off all of the waste and arrive at a completed tenon. I recently picked up the Easy Wood Parting Tool, and thought this would be a good opportunity to put it to use. I used the parting tool to define the shoulder of the tenon, going to final depth. The narrow cutter (1/8″) meant that the tool sank to the finished diameter of the tenon swiftly, but with a lot of control. I then used the shoulder as my guide to shape the rest of the tenon with the Easy Rougher. This also gave me an excuse to use the callipers from my Great-Great Uncle Bill’s Starrett layout kit, setting the callipers to the diameter of the tenon and working the blank down until they just slipped over the middle of the tenon.

_DPP6842

Octagonalising the leg with the No.62

Once the tenon was defined, I tapered the square section of the leg down to 7/8″ at the foot, before laying out the octagonal facets. It was then a simple (and entirely familiar) matter of octagonalising the leg with the No.62 (still on test) until the facets were even all the way round the leg, and tapering smoothly.

_DPP6853

Texture, facets, and chamfers as far as the eye can see

At present the octagon at the taper is a touch fatter than the legs for the Apprentice’s Stick Chair, and I am wondering whether I should thin down the dimensions at the top end a little (while keeping the foot at 7/8″). A test fit of the leg in the mortise will help to judge whether any adjustments are needed to the thicker end of the leg (and then it will be on to the remaining two legs). But otherwise I am pleased with how this leg looks, and the crisp facets of the octagon adds another dimension to the chamfers, and scalloped texture, of the underside of the seat. For the sticks I’m planning a soft, hand-rounded finish, as crisp edges on those would not make for a comfortable chair. This chair is coming on nicely, and I am looking forward to having it legged up soon.

_DPP6658

Scrub plane in a mountain of maple shavings

One of the joys of revisiting a furniture form you have previously built is the opportunity to explore the effect of small changes to either (or both) the process of building the new version, and also the design of the finished piece. This can either be intentional changes in design or process, or prompted by the material at hand. When I broke the maple seat blank for the Surprise Chair out of the clamps I decided to try a slightly different process for the build than I had for the Apprentice’s Stick Chair, and also to take a different approach to some of the design aspects.

_DPP6800

Laying out the leg positions using the pattern for the Apprentice’s Stick Chair

Fundamentally this chair will be to the same design as the Apprentice’s Stick Chair – the same leg and stick angles, dimensions, and seat shape. But what I want to achieve is a different feel for this chair. With the Apprentice’s Stick Chair I deliberately went for softened lines, irregular facets on the legs, and a slightly folk craft feel which leant itself well to the oak I was using. The maple I am using for the Surprise Chair suggests crisper lines, with regular facets and chamfers. This has in large part been an idea prompted by the seat material. The oak I had for the Apprentice’s Stick Chair was 1 1/8″ thick in the rough, and finished out at 1″ thick, which meant that I did not have any depth to play with for chamfers on the seat. The maple stock for the Surprise Chair was 2″ in the rough, which meant that I had plenty of spare material to play with when it came to chamfers.

_DPP6806

Drilling the leg mortises.

 

After cleaning up the top surface of the seat, I thicknessed the seat to 1 5/8″ thick using the Lie-Nielsen Scrub plane before shaping the seat. The scrub is the perfect tool for this sort of operation – it removes material at a rapid (but controlled) rate, and also leaves a delightful scalloped surface texture. With the seat at final dimension and shape, I flipped it face down on the bench and laid out the location of the legs and sight lines using the pattern I made from the Apprentice’s Stick Chair. After clamping the seat to a sheet of sacrificial ply, I drilled the leg mortises using a 1 1/8″ Wood Owl bit in my 1923 North Bros brace. Previously I had drilled the stick mortises for the Apprentice’s Stick Chair once the chair was legged up, but I was in a drilling mood (brace and bit makes for a very addictive method of boring holes) so I turned the seat the right way up and laid out the stick positions using the same pattern before drilling them with a 1/2″ Jennings pattern bit in my brace. I won’t know for sure until I’ve made the sticks and fitted them to the seat, but it did feel like drilling to consistent angles was easier with the seat clamped to the workbench instead of being on it’s own legs. So this is a process change which I may adopt going forwards.

_DPP6808

Chamfering the underside of the seat

Now came the fun bit – chamfering the underside of the seat. The historic chair I have based this build on had a seat of 1 5/8″ thickness in the middle, with edge chamfers down to 1 1/8″ at the edges, so I decided to follow that example. I laid the chamfers out with my Bern Billsberry pencil gauge, and planed the three straight chamfers with the Lie Nielsen No.62 . The curved chamfer on the rear edge of the seat was cut with a Veritas spokeshave. As a final touch, I then chamfered the two front corners of the seat.

_DPP6816

My favourite element of the seat so far – intersecting chamfers and lines

As I mentioned earlier, this is fundamentally the same chair as the Apprentice’s Stick Chair. But already I am seeing how small design changes can have a significant impact on the overall form. Next for this build is making the legs, and while I will be using  the same leg dimension as for my previous chair, I am thinking of tapered octagonal legs instead of the hand-rounded approach I used last time. That should support the deliberate clean lines of this chair, and I am looking forward to seeing how the octagonal legs interface with the chamfers on the underside of the seat.

_DPP6820

The contrast between the smooth chamfers, clean lines, and textured underside of the seat makes for a very tactile seat.

The Autumn of Maple and Pine

IMG_0591

Here you had an “all assembly needed” flat pack book case and stick chair. TIme to turn that stack of maple into something useful.

Since the start of the year I’ve had the stock for my boarded bookcase stickered neatly at the side of my desk, underneath the timber for a Welsh stick chair.  The bookcase design (from The Anarchist’s Design Book) is one I’ve been looking forward to for a long time, as it looks like a fun build and will liberate a lot of my history and woodwork books from the boxed purgatory they have suffered since we moved house. I decided to build the bookcase out of maple to match the Staked Work Table I finished in January.

_DPP6527-2

Removing a live edge from the maple seat

Unfortunately sourcing wide enough boards in the UK seems to be a challenge, so I’ve committed to gluing up a pair of boards for each of the sides and the three shelves in order to reach the 13″ width needed (a reason, perhaps, to move to Kentucky? I hear that such boards are in plentiful supply). If nothing else, this will give me plenty of practice with long edge joints, which is always good to have. The other project on the to-do list is a variation on the Policeman’s Boot Bench for our hall (in pine), which I promised Dr Moss I would finish before our annual Christmas Tree trimming in early December. I’ll be starting the boot bench in October, so I thought that I would use the remainder of September to build a steam box so that I could finish off the Apprentice’s Stick Chair, and also start gluing up the panels for the book case. . Although I don’t normally move between several simultaneous projects, I will be staggering the bookcase build in between stages of the boot bench and hopefully doing so will be a positive experience.

_DPP6532-2

A stick chair seat in the clamps

While I was thinking about working on several projects at once, and had the glue warming in a mug of hot water, I decided to joint up the seat blank for another child sized Welsh stick chair (and now I’m thinking that the autumn is looking very busy!). This chair will be all maple, and be a little different to the one I am building for the Apprentice. The 2″ thick maple seat was made up of two boards, and jointed very easily before going in the clamps to cure over night.

_DPP6539

Laying out the mortises for the

While I waited for the glue to cure I finished making the chair pattern I started a few weeks ago. While I’ve made plenty of guitar templates, it is not somthing I’ve done for furniture. For chairs it makes a lot of sense as there is a great deal of construction information to collate if you want to make another version of the same chair (and I do) – mortise positions, resultant angles, sight lines, seat dimensions and curves. I intend to use this pattern as an aide memoire rather than a concrete design to follow slavishly – this way all of the information I need is in one place, but I can still change the details and proportions as the whim takes me. The pattern is on 6mm ply, which means that it was easy to work but should be durable for years of use.

With the pattern complete and the seat blank clamped up, I decided to get a start on jointing the first side of the bookcase. I started off by levelling the rough sawn edges with a No62 plane that I’ve been testing for an article in Furniture & Cabinet Making. The No62 is shorter than I would like for a 48″ long edge joint, so I then moved to my usual No8 jointer. I quite enjoy edge jointing – the Staked Work Table build was good training for long edge joints, and I was looking forward to the practice of jointing five pairs of boards for the book case. Maple can be an unforgiving wood to edge joint – being very light in colour the glue line can be glaringly obvious unless you get a good tight joint off the plane, without relying on clamp pressure. The key (as with many woodwork operations) is patience.

_DPP6549

Jointing the first set of boards for the bookcase

Unfortunately, by the time I had a good clean joint the temperature had started to fall, and while the glue was good and warm in the pot (I warm Old Brown glue to the recommended 120-140F), it started to tack up while I was pulling the top board into position and setting the clamps. It was now 13C in the ‘shop, and I wasn’t confident that I would get a good bond with the temperature dropping so rapidly. Removing the clamps and washing the jellified glue off both halves of the joint wasn’t how I had intended to spend the late afternoon, but you only get one chance to nail a glue-up. With the joint cleaned and dried, I moved the clamps and timber into the house (which was mercifully warmer) and had a much less eventful glue-up in the kitchen. It is definitely getting to the time of year where any ‘shop glue-ups have to take place earlier in the day, or else in the house (another reason to move to Kentucky, perhaps?).

Over the next couple of weeks I’ll move my way through the stack of maple in the music room waiting to be glued up into panels for the bookcase, and will also progress the maple stick chair (as well as building a steam box and finishing the Apprentice’s Stick Chair. There’s a fair amount going on!). Juggling multiple projects will hopefully teach me a few valuable lessons, as well as watching various things take shape.

A Welsh Stick Chair for the Apprentice – Part 8

I was hoping this would be the final blog post on the Apprentice’s Stick Chair build, save for some progress photos of painting it. For reasons that will become clear, the chair is not quite finished yet, although there have been some valuable learning experiences.

But that’s for the end of the blog post – first let’s rewind a bit. Once the glue had cured on the bending forms I broke them out of the clamps and cleaned up the curves with a 2″ flush trim bit in the router – while I find it very hard to get excited about router bits, this bit from LMII is wonderful for taking a final pass and cleaning up the edges of electric guitar bodies (the main reason I bought it).

_DPP6489.jpg

Preparing the comb with a L-N No.62

I then cleaned up the comb blank with a Lie-Nielsen No62 plane, which I’ve been testing for an article in Furniture & Cabinetmaking. With the comb clean and square on all sides, and the centre line marked on the reference edge and face, it was game time. I’ve not built a steam box yet, although it is very much on the to do list as I get deeper into steam bending. So to steam the comb for this chair I took instructions from The Anarchist’s Design Book and poached the comb in a pan of hot water in the oven. It turns out that our oven isn’t quite wide enough to take a 17 1/2″ long comb, so I had to wedge the comb in at an angle, with one end out of the water. Several layers of tin foil later to seal in the steam, and I left it to poach at 230 degrees for an hour and a half.

IMG_0467

Ready for poaching in the oven.

Once the steaming session had finished, I sprinted (with a very hot piece of oak in my hands, and the BBQ smell of toasting oak in the kitchen) to the ‘shop, and clamped up the comb in the bending form, being sure to align the centre lines on both halves of the form with the centre line on the top edge of the comb. Nothing exploded in a hail of oak shrapnel, and the comb appeared to be well steamed across its length, so I was hopeful that this initial foray had been successful. With everything clamped up firmly and the comb conforming to the shape of the form, I left it for six days to return to equilibrium moisture content and settle into the new shape.

IMG_0468

Clamped up in the bending form – nothing exploded, and the comb conformed to the curve

Which brings us nearly up to date. Yesterday afternoon I removed the comb from the form and was pleased to find an even bend. Yes one end was a little charred, but that would disappear under a couple of coats of milk paint. I gave the surfaces a final clean up, and drilled the mortises for the sticks. The comb slipped onto the sticks nicely for a dry fit, and the Apprentice came to join me in the shop to sit on her chair for the first time, which she thoroughly enjoyed. By this point the comb had been out of the bending form for maybe 40 minutes. And it was then that I noticed – it was startening to straighten out. By the time I had cleaned up and put my tools away, the comb had lost probably 1/4″ of the curve. This would not do.

IMG_0503

40 minutes after coming out of the form, the comb has lost nearly half of the curve. Game over.

Now, having returned to Peter Galbert’s Chairmaker’s Notebook (my go-to resource when it comes to chairmaking)  and spoken to people who build chairs far more regularly than I, there seems to be a couple of possible reasons for this:

  1. The oak was kiln-dried, which can make steaming less successful;
  2. Having one end of the comb out of the water meant that the effect of the steam was inconsistent; or
  3. I offended the steam-bending gods somehow.

Although I would have liked the Apprentice to use her new chair sooner, I’m not feeling too disheartened by this. It seems a right of passage for every aspiring chairmaker to have an unsuccessful steam bending experience (often many), and I want this chair to be right. I’m going to build a proper steam box, and find some air dried oak for a second go at steaming the comb. If that fails, then I will go “full Welsh” and cut a curved comb from solid material, no steaming necessary. So this is a good learning opportunity.
