Bowl carving one-to-one workshop

Carved green wood bowlsA great day today teaching Sam Robinson  on a one-to-one workshop at Sprint Mill. Sam is a current apprentice on the Bill Hogarth Apprenticeship scheme, now in his second year. We’d been talking about various crafts a couple of weeks ago and he asked me to run a course to learn how I carve bowls and  improve his technique.
We started by looking at some of my carved bowls and discussing the design elements involved,   importance of balancing the bowl by knowing which areas needed to be left thicker and where it could be carved finer. Sam was also keen to see some of my spoons and the finish I achieve solely through carving and which he’s aspiring to.
Carving with the adzeSam had brought along some birch logs which were really fresh and ideal for the project.  Once cleaved in half with a froe we began immediately with marking out guidelines for the bowl and axing out a twist in the wood.  I always start by establishing a flat surface for the base of the bowl. This makes it sit stably on the bench and acts as a reference surface for marking out the height and measuring the depth as you carve. Flattening the top surface at this stage is a lot of work that will then be carved away when hollowing.
These one-to-one courses are great fun to do as I can fit the content exactly to the student’s skills and learning goals. It also gives me chance to put in lots more information and ‘tricks of the trade’ that there wouldn’t be time for with a group. A quality final product comes from well thought-out design and I showed Sam some tips on marking out for the bowl shape before we got onto the adzing. From our previous conversation I knew was an area where I could really improve Sam’s technique and his efficiency in hollowing the bowl. Sure enough, after a short demonstration, the chips were flying and the bowl started to take shape. Working with an adze is fun and exciting; like the axe it can swiftly remove large amounts of wood but can equally, in skilled hands, work extremely accurately. When I’m carving, I like to work right up to the line and leave a smooth surface with the adze, so there’s only the refining work to be done.
Beautiful smooth shavingsBefore that though, we flattened the top surface of the bowl then remarked our shape and did a little more work with the adze before moving on to using gouges and knives. I had brought a selection of tools that I have used over the years for carving bowls, explaining their pros and cons. I demonstrated how I push the wide gouge through the wood using my body weight and hand positions to add power which then leads to controlled cutting and a smooth finish. Sam is well used to working with tools of course and a quick learner so he quickly picked it up and before long had a bowl full of beautiful shavings. As well as the gouges, we used a selection of hook knives including one long-handled knife designed especially for bowl carving, cutting across the grain to smooth the bottom of the bowl.
The other area that Sam wanted help with was in defining the outer surface of the bowl. He had picked out one of my spoons he especially liked as inspiration for his design and I explained how the same principles of wall thickness applied to both the bowl of a spoon and a large bowl. With a combination of axe, gouge and knife he worked on defining the shape, learning for himself along the way the importance of the initial design stages and the challenges of marrying the sides, ends and handles together.

One-to-one sessions can be catered to your own goals but could include

  • Spoon carving and design
  • Hay rake making
  • Learn to carve fan birds
  • Make and use a shavehorse
  • Steam bending wood
  • Axe and knife techniques for various projects

A day with me in the workshop costs £150 including  materials and use of my tools. Or share with a friend for £250.

Crosscut Saw Jointer & Raker Guage

A flurry of posts this week which is unusual. There’s often lots going on but I don’t always get around to posting about them.
Anyway, today I got a stage further with my project to start properly using my two man crosscut saws with the arrival of a jointer/ raker guage which I bought online from America. This one is a ‘short’ jointer made by Atkins & Co of Indianapolis. It’s marked as being patented ‘May 5 74’ which, the more I think about it, could be 1874? Well, aside from a bit of surface rust, it’s in great condition and I’m pleased to see there is still a thin shim of paper under the raker guage plate where the previous user set it up for his saw.

For sharpening, a flat file is clamped into the tool and bent to match the arc of the saw teeth using the screw thread. The file is then run over the teeth to file them all to the same length before they’re sharpened. The raker guage sets the distance below this arc of the raker teeth which clear the sawdust from the saw cut. I’m looking forward to trying it out.
There’s a lot of interest in two man saws here in the north-west of England and I’m planning to organise a day this year for people to get together and learn about their use, sharpening and maintenance. If you’re interested in taking part, send me an email steve-tomlin[@]hotmail.co.uk

Blue spindleback dining chair

In between everything else I’m spending quite a bit of time at the moment on designing a series of chairs. I’ve been making green wood chairs since I did a course with Mike Abbott in Herefordshire in 2003. I did a short spell as one of the assistants on his courses before heading off to concentrate on my own green wood craft.
My chairs are post-and-rung frame chairs, often known as Shaker chairs after the american religious community that made and popularised the style. For my own chairs I’m working on slightly different designs, seating materials and finishes to produce a range of chairs with a traditional heritage but a contemporary feel. As always I’m experimenting with the craft and trying to push it forwards.
This chair is my first spindleback. It’s important to get the spacing and angle of the spindles right so the chair is comfortable; a centre spindle is definitely to be avoided as this is where your spine will sit. The chair is made from locally grown ash with steam bent back posts to tilt the back which gives support and comfort. It is painted with my own made tempera paint, a mixture of egg, oil and water as used in paintings by the ‘Old Masters’. I love how the paint has an organic, aged look to it with the grain of the wood still visible, as though this is a chair with history. To complement that feeling I’ve used ‘antique’ paper rushes to weave a traditional rush pattern seat.
These chairs are made to commission and cost £255 + p&p. Please email me steve-tomlin[@]hotmail.co.uk to discuss your requirements.

Saxon Peening Station

I’ve been sent some photos from Michael Stibane in Germany of his peening station which his great-grandfather, who was a cartwright, produced and sold.
Peening is done on a flat anvil and by altering the string on the upright pole, the angle of the blade on the anvil can be altered. Peening with the scythe blade and snath attached is common where they are joined together using a simple collar and wedge. Fitting and securing them is more time consuming than with a modern collar so once the blade is set up correctly and fixed, they are kept together so as not to disturb the arrangement.
Michael says:

The can is for water. I learned, while peening, you have to apply water from time to time to the point of the blade you are peening. So I dip the hammer into water every ten or twenty strokes. Grandpa told me, it tempers the steel. Seems logic to me: hammer-steel-deformation-heat-water-tempering :) .
As far as I know the peening station is not traditional for my area (Eastern Ore Mountains). Most of our people here have a flat anvil on a wooden stand with a peg. They stick it into the ground on a slope, sit down on the grass face to valley and start peening away with snath attached.

I’m not sure about the tempering theory for the water but I have seen knifemakers wet their hammer while forging which then gives the steel a ‘polished’ surface.
Follow the link to see all the photos, including measurements, of the peening station.

Michael also sent me a link to a Hay Camp taking place in the Eastern Ore mountains near Dresden  July 6th – 22th 2012. If you go, please email me a report!

Adze, bowl knife and other handles

Anyone getting tired yet of seeing photos of my tools post-fire? Fear not dear reader, I’m nearly at the end now.
bowl knife, adze and chiselsLater this week I’m teaching a 1-to-1 course on green wood bowl carving for Sam Robinson, one of the Bill Hogarth Coppice apprentices. It’s something I really enjoy doing, partly because it uses such a simple tool kit, my hollowing adze and large hook knife being principal among them. Sam has done a little carving already and is looking for some tuition to improve his efficiency with the tools and final finish. I also want to spend time with him focusing on design and the overall balance and shape of his bowls.
So, more ash carved or turned on the pole-lathe and fitted with the original ferrules that I sifted out of the ashes. The adze is wedged with oak, left long so I can tighten it up if needed as the handle dries fully. My tools will never win a beauty contest and I’m still sad to know that despite my best efforts they’re not the tools they were. If nothing else, I’m now really good at carving and fitting handles. I’ve been thinking of making some spares in case I need to do this again but maybe that’d be tempting fate..

Curach frame building

The curach project is underway. Yesterday Edward, Ian and I spent a terrific day working together at Sprint Mill to build the frame from spruce. A local carpenter had machined the pieces to size for us and Edward’s son kindly cut the curved shoulder pieces with his bandsaw though in future we could easily do that with a turning saw.
As this is our first curach there was plenty of time spent scratching heads, discussing details and double, triple-checking measurements. There’s pleasure in the making so no need to hurry and the day flew past. It’s a very simple construction with bolted lap joints though getting the angle between the shoulders and the gunwales took some thought. The next one will be easier and we’re definitely planning a ‘next one’.
comparing old with new boring the couple holes
After lunch we took a trip over to Edward’s woods to make the most of the daylight and with Paul & Kirsten’s help cut 50 hazel rods 6ft long and ‘light & fine’ for the hull ribs, called ‘couples’. This will give us a few extra for while we’re learning to bend them into place.

Back in the workshop we used a string line to check the alignment of the frame, kerfing the joints in the bow for the fine adjustment.

Rightly pleased with our day’s work we settled by the fire for a celebratory drink. Ian brought out the ‘tasting kit’ and led us through a sampling of some excellent Islay malts. If only every day was like this.
a fine end to the day

Purple birch bark

Volunteers being welcomed to the woodsOn Sunday I organised a group of volunteers, the NW scythe ‘gang’, to do some coppicing in Edward & Romola Acland’s woods. It’s a 2 acre hazel with standards woodland that Edward & Romola have been working for about 20 years. When they bought it, it was overstood and hadn’t been worked for around 30 years. Since then they’ve brought it back to a beautiful example of coppice almost entirely using hand tools. This was a chance for us to see a well-managed and productive woodland and learn about the many products that are cut from each hazel stool including hedging stakes, bean poles, pea sticks, garden stakes and of course firewood.
While we were working, I spotted some birch logs leaned up against a tree which Edward said had been cut last year for firewood. So when we stopped to eat I had a try at harvesting some of the bark. In spring when the sap is rising, the bark peels away easily whereas this needed a lot more coaxing and felt more brittle. Nonetheless I got two good sized pieces and brought them home.
harvesting birch bark purple birch bark colour
Birch bark basketsThe inner side of this bark is much darker than of the spring bark so I started to wonder if this is ‘winter bark’. In countries with a tradition of working with birch bark, bark is harvested in the dormant season for the darker coloured layer inside. This is scraped away to reveal the lighter bark underneath and make patterns and designs on the finished work, like these baskets by Jarrod Stone Dahl.
I contacted Jarrod for advice who said that they call this ‘purple’ bark. It’s considered a lower quality and folk over there don’t tend to bother with it. One problem could be that there won’t be much contrast between the colour of the two layers. Still, we agreed that you’ve got to work with what you’ve got and, since we don’t have such good sources of birch bark in the UK, I’m going to see what I can do with the pieces anyway.

Peening hammer

peening scythe bladeThe first stage of sharpening a scythe is to peen the blade, drawing out the edge to thin it and give the right bevel angle. When you start out, the peening jig designed and made by Schroeckenfux along with Peter Vido is a good way to go; it’s quick to learn, relatively foolproof (but not without some care and attention) and will give consistent results. As your mowing progresses though you’ll start to see the limitations of the jig and want to learn to peen your scythe freehand with hammer and anvil. This will enable you to achieve a finer edge, different bevels for different vegetation and more control over the whole process.
I talked in an earlier post about setting up your peening station so now I thought I’d mention a piece of the kit that is often overlooked – the hammer.
With the jig, the hammer isn’t contacting with the blade so any hammer will do. In freehand peening, the anvil and hammer are two parts of the same tool; equally important and useless on their own. The face of each should be kept clean, polished and free from dents otherwise these marks will be imprinted along your scythe edge with each blow. If you’re at a scythe festival and looking for a hammer, you’ll struggle to find someone who’ll lend you their’s. Too many of us have seen them ruined by denting the face by using it for hammering nails or on the cap of a jig.
peening hammerWhen I started out peening, I cleaned up and handled an old carpenters hammer which served me well but wasn’t quite heavy enough. About a year ago I was visiting Gerhard Wagner in Austria and he explained that the hammer should be heavy enough to do the work simply from the force of letting it fall rather than actively ‘hitting’ the blade and suggested using hammer with a head weight of around 600g. There were a few other factors I wanted and, after a lot of searching I finally bought my new peening hammer earlier this year.
peening hammersMade by Britool and sold as a riveting hammer, it has a nicely designed head with a rectangular cross-section at the flat face. It also has a cross-peen face and weighs in at 650g so ideal for peening. When it arrived I used some wet and dry paper to soften the sharp bevels at the edges of the flat face and shortened the handle so it’s now just 160mm long. To maintain accuracy and consistency in your peening it helps to tuck the elbow of your hammer hand into your side, restricting it’s movement. A longer handle prevents you doing this as it catches on your thigh and since you’re only using the hammer’s own weight, the extra leverage of a long handle isn’t necessary.
The faces of this hammer are nicely domed and I’m enjoying using it, both with the flat face and with the cross-peen face on a flat anvil.

Transylvania Haymaking Festival dates & Scythe royalty

Haystack buildingI’ve just been sent the dates for this year’s International Haymaking Festival in Transylvania. The fourth festival will take place on 19-26 August 2012 in Gyimes, Transylvania. Last year’s festival was a wonderful week and the event grows and improves  year. Hosted by a local farming family and the Pogány-havas Association this is an opportunity to mow some of the most species-rich hay meadows in Europe and learn about how to make hay and build the beautiful, iconic haystacks that you can see throughout the region. The work helps to bring income to the region, highlighting and aiding the work to preserve these meadows.
To book a place, contact Barbara Knowles a british biologist and science policy adviser to the Society of Biology, UK who works with the  Pogány-havas Association. Visit her Treasures of Transylvania website for more on the  region.
Prince Charles with scytheIf you need more convincing that the area is special and that mowing is for everyone, in May HRH Prince Charles visited the project and had a go with a scythe. It turns out he’s been visiting the area for years and likes it so much that he has a home out there.
