(George Pastuch - Editor) 0431834472 From the President’s Shed My tour of the Woodgroup Clubs continues with a visit to the Fleurieu Woodturners in early May where all present learnt how to carve a clock surround using basic tools. Unfortunately I had to leave early and will have to finish my carving without the expert guidance provided by Des. Show and tell included quality items produced by relatively inexperienced turners. Keep up the good work guys. I also attended the Murrayland Turners in late May where Brendon Stemp once again demonstrated his innovative approach to turning in wood and resins. All present on the day had a great time and despite Brendon stating he would not take offence with anyone going to sleep after lunch I am not aware of anyone who did as no one wanted to miss any aspect of the demo. I have attended two shows at the Wayville Showgrounds over the past month or so and if patrons follow through on their promises several clubs should get new members as a result of the spruiking by Southern Turners members. Let the wood chips fly John Tillack 1 WoodgroupSA Network Meeting, Tuesday May 10th, 2016. Trevor Lloyd was first off the blocks with firstly, an almond bowl about 300 mm diameter, which he had rescued after Jeff Wrigley consigned it to his firewood pile, when a large crack across the bowl got larger. Trevor reworked the piece, filling the “through” cracks with brass powder in resin. The result was a quite successful rework, the brass blending in with the fairly strong colouring and grain of the wood. (Almond appears to be a notorious wood for splitting badly, in spite of sealing the ends immediately after cutting). His second offering showed two “Lichtenberg” pyrography efforts, which he and a friend generated by applying a high voltage across a plywood board that had been made electrically conductive with a baking powder solution. The tracks produced by the electrical discharges down the board wherever the conductivity was highest, burned a quite artistic “dendritic” and “fractal” pattern, some quite deeply. The operation is inherently dangerous according to electrician Trevor, but the results can be stunning. (It is a modern artistic resurrection of work done in 1777 by Lichtenberg on the electrical breakdown of insulators!) Roger Humphris was next with a bottle-mounted candle holder, based on one illustrated in the Australian Woodworker magazine some time ago (November/December 2003 issue, p67). The candle-holder was turned out of redgum, was about 100 mm high, with a maximum diameter about 50 mm, with a metal insert for the candle. Because bottles were in short supply in his shed and house, he managed to find a genuine “Pickaxe” bottle that had slumped in a fire. His candle holder, with its double flange, thus had a more avant garde shape than the original John Bennett seemed to be into ash (Fraxinus excelsior) bowls currently, as he passed a roughly 100 mm diameter one around, unfinished after remounting on a stub, and partly turned at the Merry Month of May weekend recently held (abbreviated to MMoM below). He wanted comment and advice on how to eliminate a small blemish of cranky grain that had resisted repeated sanding through the grits, forwards and reverse sanding on the lathe, and hand sanding the offending region, with minimal effect.

He will see! Mel Pearce’s first piece was an “inside-out” turning about 100 mm tall, a flower form on a 40 mm diameter base, with a partly hollow stem, turned at the MMoM meeting. The impetus for this “inverse” or “involute” item (consisting of 4 blocks carefully glued together, turned to one shape, split along the glue lines, each piece rotated by 180, reglued and turned to a different shape), came from a demonstration given by George Pastuch on the Sunday. George generously provided a supply of already internally shaped, reglued blocks to encourage anyone to give it a go, which Mel did with the result shown. His second piece was a segmented genie bottle about 250 mm tall, with circular inlays, made some time ago out of several timbers –mahogany, hoop and huon pine among them. He had lacquered the bottle recently, and still had some finishing work to do on it. Because the genie was forever escaping, he turned a stopper out of huon pine to fit, in the May meeting. That kept the blighter in and everyone happy. (The bottle is resting on Mel’s flower in the image). Estelle Pearce’s contribution was a very decorative and delicate carving-cum-picture, inherited from her mother. The Asian female spirit form was minutely carved from very thinly sliced bamboo. That was mounted in a frame. Its precise history was unknown, but the execution of such fine work must have involved great skill and incredible patience. Sorry, there is no image Graham Were was another MMMoM participant, and had picked up on George Pastuch’s work on involute forms too–his decorative pendant ornament version this time, shown at right. At home he gave it a try with a piece of Obeche (Triplochiton scleroxylon) machined into 4 identical rectangular blocks with square cross-section. (Obeche is a pale cream timber, quite light, from Africa, and a bit splintery, according to Graham). Because involute work requires very careful centring of the glued up square-section pieces on the lathe, he first routed a small bevel just on the ends of the pieces on what were to be inside and outside corners once the pieces were glued together. After glueing the 4 blocks at just the ends, the bevels formed a recess into which a conical drive point or live centre fitted, thus ensuring concentricity –smart thinking. Graham then turned the outside profile which later was to become the inside. He turned the profile to make a larger windowed part in his pendant than George had demonstrated. Splitting the blocks along the glue line, rotating each piece by 180º, and reglueing them together (Continued on page 4) 3 (Continued from page 3) in the right order, he turned the outside to the required shape –and discovered that the inside recesses (formerly outside) were almost too large –but the piece still held together, to yield a quite decorative item. Eddie Jones was into one-piece pens (i.e. without a join in the middle), so showed three of his latest creations. The three pens had cherry, oak, or olive “skins”, one decorated with some fine circumferential rings, and all attractive to look at, and quite comfortable to hold. Alex Mühlhölzl had a couple of items to show. The first was a tiny bowl, about 25x 30 mm in plan, turned out of pine knot or burl. It was well executed, right to its base, and of course, signed, with the wood identified. His second piece was captured from a bunch of borers that were escaping from his shed carrying a log of apple. He managed to find enough wood in that to make a roughly 100 mm diameter bowl that exhibited strong and eye-catching grain and colouring. Alex decorated the small rim (just visible in the image), and a collar around the base with 2 mm pyrography embellishments, to produce a most attractive piece. John Beswick showed an ebonised red-gum bowl with white mouse, destined for a recipient who liked a “black and white” theme. The bowl, about 250 mm in diameter, was turned to a spherical form with about a 15 mm thick wall, remounted at an angle to the top opening using a jam chuck, and a flat turned to form the base, reducing the wall thickness there to a few mm. The top edge was then cut away and scalloped to shape. Several coats of iron ebonising brew were applied, sanding between coats, to blacken the inside and outside surfaces of the bowl, apart from the very bottom. The white mouse was turned out of artificial bone (very expensive medical material, but very uniform in texture and completely white), with white ears, pink eyes, and a black tail added later, before mounting it on the bowl rim to complete a striking piece John Tillack had a bunch of things that he had worked on this past month. First up was a steel post he had made to fit onto his Sorby Pro-Edge sharpening system, so he can sharpen gouges quickly and reproducibly to the same angle. He then showed a shallow winged bowl cum platter, all turned out of green pear-wood bought from the wood sale at the MMoM meeting. He carved the thin wings to a wavy shape using an Arbortech cutter, and shaped the underside likewise, but with three short feet to support the bowl. A fine piece, yet to be seasoned, that the image does not do full justice to. His third piece was modelled directly on the Macfarlane bow sander, devised in the Evan Dunstone workshop in Canberra, and extolled in the Australian Wood review, number 88, p8, quite recently. The sander made smoothing continuously curving (Continued on page 5) 4 (Continued from page 4) surfaces a breeze according to John, was simple to construct (3 pieces of wood), and in which it was easy to replace abrasive grits. The next meeting will be on the second Tuesday of the month, 14th June, 2016 at the San Georgio Community Centre, enter off Henry St, Payneham, 7 for 7:30 pm start, until about 9 pm. The bar will be open as usual, and for coffee, tea, hot chocolate, fine wine, soft drinks, etc. As usual, carvers, sculptors, whittlers, scrollers, pyrographers, toymakers, furniture and jewellery makers etc. are all most welcome. Western Woodworkers Inc. Western Woodworkers have again had a very good year. Very informative Saturdays and everyone being guided to a letter level of woodcraft. Four members again event to the Gold Coast to attend Turnfest. A venue which showcases the work and techniques of renowned wood turners from worldwide countries. A huge opportunity to see and learn, first hand techniques of woodcraft on a higher level, this gives a new train of thought and ideas exalate. Timber enhancement sky rockets and ideas evolve. Next year’s Turnfest turns 15 years of age, and a huge contingent of worldwide wood turners will be attending. It is truly a wood turner’s paradise. Watch for low coast air fares, and the expense of the trip is much less. Our usual Christmas and Christmas in July events are well attended of fresh choice, Diagonal Road Sturt SA our Woodcraft display at West Torrens Library Auditorium 1 Brooker Terrace Hilton begins on Saturday 29 th of October to the 6th of November inclusive 2016. Wishing everyone and their families good health Rena Hoare 5
