Spalted woods. Which wood to spalt?

Which wood to spalt?

Spalted Beech bowl

Oops, nearly went too far!! Spalted Beech bowl. The brown patch in the middle is the only place where the wood hasn’t been affected by the fungi. Also note the blue colour, sometimes completely surrounded by a black line.

Beech is by far the easiest wood to spalt well. It almost always ends up with black line and distinctly different colours. This bowl shows only one area left with the wood in its natural state. All the rest has been affected by fungi. I don’t know how many different ones. It was at the very limit of having enough structural integrity to work. Even with the gauge straight off the grinder it was difficult not to get tear out on the end grain. This wood had been left outside in all weathers for a year and a few months. It was a large tree and most of the rest of this plank was perfectly spalted (though sadly I didn’t take any photos and the bowls have gone!). However, it would have been better if I’d worked it a bit sooner. I also put some under shavings outside. I turned one piece after a few  months and it had hardly started spalting. Now, it is a bit over done!

Ash will spalt with the beautiful black lines but it isn’t as consistant as beech. Oak can get darker which is beautiful, but eventually there are white specks and soft pockets. Sycamore tends to go grey but can be a soft and beautiful colour.

This is the same Walnut having been left in the weather for six months or so.

I was given a Walnut tree. The only walnut I’d turned before was black walnut. Imagine my disapointment when I turned this bowl, so pale, the colour so insignificant. I am afraid I just left the rest of the tree lying in the yard, only for six months. Honest. And when I turned more this was what I got. Isn’t it lovely?

I had a similar experience with horse chestnut. Very plain grained when it was green but leave it out to weather for a few months and it was like a pale marble. Beautiful.

 

Burr Elm bowl. Half spalted. Sometimes it works out wonderfully!

Elm is probably one of the most disappointing woods to spalt as it just tends to lose its colour, integrity and vibrancy. But if it has only just started it might be ok or even enhance a bowl by the contrast. But certainly not worth deliberately doing.

This tree was hollow and rotten in the middle which is why there is such a clear contrast between the spalted and the good wood. I am sure if this had spalted after felling it wouldn’t have been so nice.

This was felled as it had honey tree fungus killing it. The light patches are where the fungus hadn’t yet got into the living wood.

Spalted wood.

Spalted wood is where fungus or more usually several different fungi have been introduced to the wood. This is most commonly after the tree has been felled but sometimes it is a fungus which has killed the tree so the timber has already been spalted. Spalted wood can be created deliberately or can occur by accident as I have found out several times over the years!

Spalted wood can be created as easily as:- Leaving the freshly sawn wood out in the weather, popping it into a plastic bag or burying the wood in wood shavings.

However, knowing when the wood will be spalted enough to work but not too spalted is as tricky as :- Knowing when to take a cake out of the oven without a temperature gauge or knowing when to put fuel in a car without a fuel gauge.

But it is so very exciting to see if you have got it right. And when it is right it feels like hitting the jackpot. Since I have become old and boring it is about as exciting as I wish life to be.

Spalted Beech

The ease with which I can glibly say the above is because over the years I have unintentionally spalted much wood. All the wood I use is local and fell naturally or had to be felled or coppiced for some other reason and I’ve been lucky enough to be able to buy the wood. So if for example I’ve had a short piece of wood which I knew would crack if left out I’ve wrapped it in plastic intending to turn it within a couple of weeks only to forget it or get distracted and not get round to it for months and then wonder of wonders, it was beautifully spalted. Other wood has waited months outside in the rain until I plank the tree trunk. So, no fuss and worry seems to work well. There has been wood tightly wrapped in plastic excluding all air, loosely wrapped allowing air, left in a damp environment without cover. They all work. The biggest hit and miss is deciding when to use the timber thereby stopping the spalting process.

 

Spalting Wood.

The best and easiest way to create spalted wood is to use green wood as this is the most natural way the fungi would be going  into wood to start the decay process. Over time and with experience it might be possible to try to regulate it by noting how long it had been left in different environments. However, in my experience there is a massive difference between different wood species and even different trees of the same species. All it needs is for one tree to be felled in the winter and another when maximum sap is rising and the difference in the wood is enormous. So there will always be an element of surprise.

I have never tried spalting a dried/seasoned piece of wood. Air dried wood would be slightly easier than kiln dried as it has a slightly higher moisure content and the cells themselves won’t have collapsed so much. To spalt dried wood I would make sure it had enough fungal spore by introducing them rather than my happy go lucky way of leaving wood around or just popping it in a bag. Pick up a few handfuls of rotted leaves or a rotten piece of wood if you can to put in the plastic bag and the wetter they are the better as you would have to re-introduce moisture too. Even more important with kiln dried wood. But it is always more difficult to reintroduce moisture to wood. Firstly it is the area around the cells which lose moisture. But after you get down to about 30% moisture it will be the moisture within the cells themselves that is coming out and the cells collapse. So creating a suitable environment for fungi to do their work on well seasoned wood is much harder.

I prefer to work the spalted wood as soon as possible after planking it or taking it out from the plastic. I find that the structure of the wood through its alteration by the fungi means that it is more likely to crack than either green wood or seasoned wood. The moisture within the wood is water not sap as it is the sugars in the wood which the fungi have been eating. So it will dry quickly on exposure to a drier atmosphere.

Spalted wood and what causes it and when and how is a little understood and much misunderstood subject. But it is just nature trying to do her thing. And the results are so beautiful, aren’t they?

 

Origin – A Makers’ Co-operative

Wednesday, August 3rd, 2016

Origin, a maker’s co-operative in Carmarthen, is a shop I am very involved with as many of you who have “liked” my Facebook page will know. Origin is a wonderful shop and I am so pleased and proud to be part of it. And it is such a really nice bunch of people.

When I first joined Origin last year I spent time looking at all the work of the other makers, trying to memorize the products to help customers. I felt humbled by the wealth of talent. And then I thought about the hours of work and the years of experience, designing, altering, developing of skills and styles that had gone into these finished articles. By now I have also been privileged to see how some makers’ work is altering and evolving over time.

The Origin Makers.

Obviously there are talented painters (list below), photographers, ceramicists (both functional ware and sculptural) and jewellers working in silver, glass, celtic beadwork to recycled copper pipe and water tanks. There’s a felt artist, a glass artist, a pen maker, a willow weaver, Jude specialises in marbling on a variety of materials. Rob is a highly skilled cabinet maker who has developed a wonderful range of turned and carved spoons recently, Aled makes very stylish, simple, elegant pieces out of Welsh slate. Then there are textiles – felted clothes and the most delicate knitted and woven work. I use the beautiful hand forged hooks to make the coat racks shown in the photos.

Co-operatives

Roni Roberts in Origin window 2Roni Roberts in Origin windowThere are commitments to being part of a co-operative. We have to contribute towards the rent and rates and we take turns stewarding the shop. Regular meetings further the progress of the shop. We have to clean, change the window displays, organise the displays in the shop, keep on top of packaging, finance, updating paperwork, the website, Facebook page and so on. Some people have been involved for many years and have contributed so much time and energy, some are new or maybe shy about contributing… Guess that is like a cross section of life really. And who knows what else is going on in people’s lives? Also we are in a rural area so many of us are an hour’s drive from the shop which doesn’t make it easy.

Roni Roberts' woodwork display in OriginI have always chosen to sell more through shops than craft fairs for several reasons. I value the high street and think that if I want to be able to shop locally I should try to sell locally. My work might be wanted for a birthday or wedding anniversary and these don’t neatly fit into when fairs happen. Also, when I started selling I was caring for my partner’s mother so was not really free to set up, steward and take down stands at craft fairs.

When I heard that Origin were looking for new members last year I was interested as I was by then free to steward and Carmarthen is a different type of town from the places I am used to being in. It has a larger catchment area but not so orientated towards tourism. I have always been in favour of co-operative so that was the icing on the cake.

Turned Miniature Eisteddfod Chair

Sunday, March 6th, 2016

Having had the honour to be commissioned again to make a miniature chair for Cymdeithas Ceredigion‘s 2016 Eisteddfod I decided to put my all into making a turned miniature chair. Since turning is my main medium for working with wood it made sense to explore this method to make the chair. I’ve made chairs for Cymdeithas Ceredigion before, both a full size chair and two miniature chairs, however I used more traditional methods for these chairs. (The 2015 miniature chair, described here and here, was made out of Laburnum and the 2014 was made of Elm.)

I had a prototype turned chair floating around the workshop which I’d made a couple of years ago. I wasn’t happy with it but felt it did have possibilities. However, translating that into something I would be willing to allow to be presented as a prize was quite another matter. My projects almost always have the natural shape or figuring of the wood as the starting point. Even when asked to make something to exact criteria usually the specific wood plays a big part (apart from replicas for antiques which obviously need to fulfil a different brief). It is the beauty of the particular wood that I want to enhance by turning it from a lump of wood into a shape that is useful and hopefully pleasing to the eye. All my other chairs had been made in this way. The full size chair, made of Ash, used the natural shape the wood had grown and been planked, the miniature Elm chair used wood deliberately chosen and sawn to create an idea of arms using the way burrs grow out of wood and the idea behind the miniature Laburnum chair (and here) was keeping all the outer edge of the chair in the sapwood whilst the rest of the chair was heartwood. All three of these chairs also used as few pieces of wood as possible again to keep the emphasis on the wood rather than the manufacture.

turned miniature eisteddfod chairThe starting point of this miniature chair was different. It was the method of manufacture that was the starting point and so it had to be based on a circular form, since I don’t do multi axis and off-centre work. Then there was how to hold it on the lathe. And finally, since I haven’t made this sort of thing before, getting the design pleasing to the eye, the proportions appropriate and balanced from all angles whilst keeping it possible for me to physically make on the lathe. I am not good at sitting down with pen and paper anyway, but I really didn’t see ay point in doing that with this project as it wouldn’t make any difference how nice it looked if I couldn’t make it. So I resigned myself to making one, studying it, making another, putting them together, living with them, viewing them from every angle, putting them away for a while to let my sub-conscious have a chance to have an input. So I now have a line of miniature chairs on a high shelf in the workshop, gathering dust.

Turned Miniature Eisteddfod ChairI chose Ash for this chair. I deliberately chose a plain wood so it was the shape that was important. It is turned from a whole branch which means the top of the back and the arms have perfect concentric growth rings.

I never like leaving things to the last minute so I have been living with this chair for a while now before it goes. I critically examine it, wonder what it would be like with different legs, a lower back or more splayed, in a different wood and so on. In fact now I’ve started turning chairs I’d love to make more.

I have posted a video on Youtube here ac yng Nghymraeg yma.

A Priceless Gift

Friday, March 4th, 2016

I received a priceless gift a few years ago in a tale with many twists and turns. I was commissioned to make a chair to be given as a prize at a local Eisteddfod. Cymdeithas Ceredigion had been bequeathed money and the Cadair Goffa Pat Neill (Pat Neill memorial chair) was to be given for a poem in “cynghanedd” which is strict metre. (I’m afraid my knowledge of the complexities of poetry in any language is beyond me. The basics of Shakespeare’s iambic pentameter is the limit of my knowledge.)

Working with wood, however, is another matter. And what an honour to be commissioned to make this chair. I immediately knew what I would like to make if the committee was willing and drew up a sketch based on local Ash wood I had seasoned and was ready to be worked. The committee passed my plans so all I had to do was put it into practice. Hmm, easier said than done…

Eisteddfod chair

I don’t like having work hanging over me and don’t work well under stress so last minute deadlines are not my cup of tea. The chair design was totally dependant on the specific wood I had so if I messed up or if the design didn’t work out it was right back to square one. I therefore wanted plenty of time before the Eisteddfod which was the following March so I made the chair in the autumn. I was very pleased I did as I had an extremely difficult time over the winter and would not have been able to make the chair. During this time I was supported by a friend without whom I’m not sure how I would have coped.

Article in the local paper with Philippa and the chairImagine my surprise and delight when it was this friend, Philippa, who won the chair. I hadn’t even known she was competing. I don’t think I even knew at that time that she wrote poetry at all, in Welsh, in strict metre…

The title of the poem was “Rhodd” which means Gift. The subject Philippa wrote about was adoption and the wonderful gift of a baby  for a childless couple. My sister is a foster carer who has looked after many babies before they have been adopted so this was yet another coincidence within this tale.

Philippa said she was very pleased with the chair and found it comfortable. As the photo in this local monthly newspaper shows it is used at her table as her everyday chair. And it was indeed a priceless gift she gave me, both of the pleasure in the chair and of her support when needed.

 

Eisteddfod Chair

Thursday, March 3rd, 2016

Miniature Eisteddfod chairFor several years now I have had the honour to be commissioned to make a chair for a local Eisteddfod. This is the first of the miniature chairs I made and the wood chosen was Elm.

An eisteddfod is a cultural festival, a celebration of the arts and with competitions in all sorts of arts from poetry, literature, music, dance, performance… The original eisteddfod happened in 1176 in Cardigan only a few miles from me. It was held by Lord Rhys of Deheubarth at his castle. Major work has been happening there for a few years now, both archaeological and restorative, since Cardigan castle came into public ownership. (There is also a shop there which includes a selection of my work on display.)

The National Eisteddfod is a very important cultural event for many people. There are fields and fields of caravans and acres and acres of tents of people staying for the week. All the local bus companies organise buses for the important days such as the Crowning and the Chairing ceremonies. The Maes (literally field), which is where the main pavilion is situated, also has representatives of all the major organisations in Wales, major businesses, charities, individual shops, organisations, anyone really who can afford it and wants to show a presence has a stall so it amounts to hundreds. The main pavilion is a very large marquee but there are smaller marquees for various other activities such as arts and crafts, the Welsh learners’ tent, technology, drama, one where the people compose poetry all week long. There is more than one “maes” too. There is one that appeals more to younger people which has bands and musicians. In the evenings there are plays and concerts. The main pavilion is where the main competing happens and include reciting, singing, playing instruments, dancing, choirs, short story as well as the various poetry competitions in free verse and “cynghanedd” which is strict metre. There is plenty of other competing going on elsewhere on the “maes”, especially writing poetry and verse. This cultural week moves each year between the North and the South of the country. It is the largest cultural festival in Europe and I think the largest in the world that moves from year to year. There are many who go who never go into the main pavilion and many who spend most of their time there. It is a chance to meet up with friends one only sees once a year. People will remember the year according to where the Eisteddfod was held or the particular Eisteddfod according to the weather.  It is many things to many people. There are people who come from all over the world. There are thousands of competitors and 150,000 or more visitors over the week. All the competitions are in Welsh and the main language heard throughout the National Eisteddfod is Welsh though obviously many non-welsh speakers also come and are very welcomed.

The giving of an Eisteddfod chair to a poet or bard is a tradition going back a long way. Lord Rhys gave a chair at the Lord’s table at his Eisteddfod. The ‘Chairing of the Bard’ at the National Eisteddfod is the highlight of the Eisteddfod and the literary highlight of the year within the Welsh language culture.

There are smaller Eisteddfodau (plural) held all over the country, for example in schools, chapels, villages and many societies, and indeed in other countries where there is a large Welsh presence such as USA, Australia and Patagonia in Argentina.”

The wikipedia entries for eisteddfodau are well worth reading for more information about these wonderful cultural events.

Tale of an Ash Tree

Friday, February 19th, 2016

Ash coffee table My work often comes from trees where I know some of the story behind the wood. None more so than one particular Ash tree. There are so many different threads of different stories that I see when I look at a piece from this tree.

Once upon a time an Ash seed rooted itself in just the wrong place, on a river bank where there was almost no soil and under a cliff so there was almost no sun either. For a hundred and fifty years and more the Ash tree grew tall and thin as she stretched to reach more light, developing a buttress on one side to hold herself upright. But eventually a storm was just too much and she fell over, her roots wrapped round stones.This Ash tree fell right across the river, over a beautiful deep pool that was a favoured fishing site, making this pool useless for the fisherman who lived in a cottage just upstream.

Totally unconnected Huw had gone to see a neighbouring farmer about a repair job on an agricultural machine (Huw is a precision engineer) and bought a beautiful curved Oak trunk, suitable for lintels. The farmer had offered this little Ash tree to him as well. So they winched it over the river, sawing it every seven foot. After sawing the last bit the base, with the roots and stones still attached, had bounced back upright in the middle of the pool still spoiling the fishing. The neighbouring fisherman returned home, donned his chest waders and retied the winch wire to pull it out.

close up of Ash coffee tableI only heard about all this but it was obvious everyone had had fun. At that time we were looking after Huw’s mother with dementia and she couldn’t be left so we took it in turns to work. When we next had someone in for a few hours of respite Huw took me to see his treasures. The Oak didn’t move me but I loved this valiant little Ash tree right from the start. The marks on the bark showed there was ripple and the buttress was interesting. We took the planking chainsaw with us and planked one of the sections and brought it back straight away in the van, the rest coming later in a more substantial vehicle, probably the lorry Jim next door had at the time.

The tree also had meaning for me as it grew within half a mile from my birthplace. The fisherman it turned out knew my mother quite well too. And, rather more poignantly, within shouting distance of the tree is the main road where a dearly beloved friend was killed in a car accident.

This photo shows clearly how slowly the Ash tree grew. But what happened that one year?

Ash treeThe trunk was only about 18” diameter whereas I also had an Ash tree about the same age that was 4’ diameter as seen on the right. The close up of a bowl here clearly shows how slowly the tree grew. But what happened on that one year?

 

The photo in my profile in Good Woodworking (the third page on the left) shows the remaining three sections of the tree. Though I had been so pleased about getting this tree it had not felt essential to plank it straight away. Getting time together to plank became more and more difficult as Huw’s mother became frailer and we became more exhausted by the situation. I think this tree deteriorated more quickly too because of its unusual growth pattern, it was a very soft wood even when fresh. So most of it was too far gone when we managed to get to it. I was so pleased the first section had been planked straight away.

Ash tree bowlI can even remember where several pieces of it went as well. There is my coffee table shown above which I never sold as I wasn’t happy with the legs. Next door had a coffee table. I made a loving cup with two captive rings for a friend’s wedding.  There is even still one bowl in my Ash collection in Origin at the moment. And somewhere in my stash of wood I think there may, just may, be one plank left…

 

 

Swallows

Thursday, August 20th, 2015

Swallows have been nesting in the sheds here since before I moved here. At that time the sheds were cowsheds and open hay storage barns so it was easy access for the swallows. These dilapidated sheds had to be replaced for workshops. Naturally when the swallows appeared the following summer from their winter in Africa (lucky swallows!) they expected to use their homes as normal. I had to refuse my workshop to them as they do make such a mess it would mark the wood forever. Huw, however, was more than happy to share his workshop space so we cut a slit in the the wall (box profile zinc on sides and roof) of his workshop for them to fly in and out as they wished.

swallowsThe first year the swallows built their nest on the south side but the shed was no longer full of holes so it warmed up too much on that side and the babies died so we stopped them nesting there. Since then they have chosen better nest sites. They were so used to Huw being around they paid him no heed as they flew around. He could even make a specific sound that would get all the baby swallows popping their heads over the top of the nest and opening their gapes for food. However, their parents would give a warning chirrup as they flew off for more food to remind them to stay quiet till they returned.

nest on nestSometimes the swallows have used the same nest the following year. This year they had no chance of that as someone else thought it was an excellent spot. Blue tits I think, but after building the nest they abandoned it so I’m not sure. However the swallows had no problem finding somewhere else and successfully raised a brood. When the fledglings were young and vulnerable the parents were most upset with Puss wandering around minding her own business. When she was following me around when I went into the vegetable garden or just sunning herself she would be dive bombed repeatedly by very noisy and incredibly brave swallows. Since she has caught a swallow years ago I know she is capable of catching them so was full of admiration for the swallows to risk their lives for their babies. However, since Puss gets told off when she catches any bird but not when she catches field mice or baby rabbits she does seem to leave birds alone. Sometimes instinct gets the better of her but only about one or two a year.

I only ever saw three babies this year until I came to take this last photo. They could hardly fit into the nest. After I’d taken the photo they all flew out so they were already fledged and I’m unsure if one of them might therefore have been a parent. They were certainly cosy in the nest by the end! I see the swallows on the phone line occasionally but they seem to have left the nest and the shed for this year. They will spend some time here again before they go off to Africa for the winter.

Wood Turning -Setting Up My Workshop 1

Friday, July 24th, 2015

My Wood Turning Workshop Starts to Take Shape

 

Some months ago I was visiting Roni and, as usual, could not wait to do a bit more wood turning. There I was turning a rather nice, if I do say so myself, mushroom when Roni asked why I did not set up my own workshop at home?

I had thought about it before and dismissed it on a couple of grounds.

Firstly there was the cost. Wood turning is not a cheap thing to set up. There is a lot of necessary kit.  A lathe for a start, have you seen how much those things cost!? Then there is extraction for the dust, gouges, saws of various types, sharpening wheels for the gouges, various oils and finishes, etc. the list goes on.  There is also a whole industry out there designed to sell the latest “must have” (for which read, “not actually must have at all” ) gadget. Even if you can resist the latest hollowing system, or the new and improved widget designed to make you a master turner that also makes tea and toast and predicts the lottery numbers wood turning is not a cheap pastime.

Secondly, there was the question of space. It is true that I have a garage but as with everyone I know it does not house a car. Instead it has all the stuff that can not go anywhere else barbeques, bicycles that are never used, half empty pots of paint that have crusts on them thicker than the earth’s. Christmas decorations that are no long used have been breeding on the shelves, there are record decks just waiting for me to set them up. There are all those things that are really necessary to maintain life that are never actually used…………..

There was also the attic (or what I laughing refer to as my office). However, the prospect of having wood dust cascading down through the house was too horrendous to consider, for more than 5 minutes.

However the seed of an idea was planted by Roni’s question. Now, how to make room, organise the area,and find the money?

Marketing Woodturning

Saturday, April 25th, 2015

Roni Roberts at workI have been woodturning for ten years now. In fact I even did a little before that, about fifteen years ago. However, most of this time I have also been a carer so not only was my time limited but also I never knew if I would have to drop everything else for a while if the person I was looking after needed more help. I therefore deliberately kept a low profile with the woodturning. I put my work into local shops and galleries and left them to sell on my behalf. I am grateful for this service. I do not begrudge shops their commission, I am a firm believer in the value of our high streets and independant shops and am as happy to provide them with my work as I am to shop there.

However, selling through other people meant that I lost out on the personal contact with my customers. Also, as I am passionate about trees, wood and woodworking I also felt the loss of a chance to explain to people that a particular bowl came from a tree that  grew a few miles away. I knew the exact spot, I knew why it had fallen or been felled, I had planked it up myself at home, delighted in it, stored it, dried it and worked it.

I am no longer a carer. This means that I can (and need to) dedicate myself more to the woodturning. However, marketing woodturning is a very different matter. I live in a very rural area therefore there aren’t that many shops/galleries around to display my work or population to buy. I need to go further afield to a certain extent. And I would like to share my enthusiasm for the wonders of local wood, woodturning and wood craft in general.

About eighteen months ago I finally got the internet for myself. I had always loved the idea of blogging about the wood as this would be a chance to tell the customers everything I’d never been able to in the shops. However, doing the writing has been a different matter. I feel self-concious, I don’t know how to express myself clearly, etc.

Then there has been all the technical problems – still ongoing. After all, I am not going to be able to learn all about the world of www overnight, am I? But I have taken a great leap forward. I made my first video and uploaded it to Youtube. Apologies about the quality – I still have lots to learn. But as my mother once said “We live on a learning planet.”
