Cam Cosford treated us to a demonstration of box making with a difference. The shape was of triangular footprint but having convex (not straight) sides. The complexities of this were somewhat baffling to many and way beyond the scope of this report to record in detail, but there were some take home messages that are worth recording for posterity:

The project was made from a blank of 150 mm dia and 80 mm long – which gives a good idea of the overall size. This can be scaled either way for personal preference.

When removing and replacing a project on a 4 jaw chuck in compression mode, mark the work opposite a known jaw number so that the item is remounted exactly as it was first positioned, using the original pressure marks. This facilitates consistently true running.

Parting off a box lid is best started using the thinnest parting tool available and completed by hand saw with the work stationary. A thin parting tool enables grain to be better matched between box and lid.

Marking out the design intentions involves careful geometric drawing. To create a triangle out of the original circular disc requires offset turning and a great deal of hit-and-miss cutting. Off-setting is by means of a custom faceplate made from 30 mm mdf and necessitates very accurate (again, of geometric quality) laying out of positioning marks. Securing of the work to the offset faceplate is assisted by means of a screw into the workpiece centre to allow rotation between the three cutting centres and blobs of hotmelt glue for security at each stop. A counterbalance weight is essential.

The feet were cunningly made by utilising the original flat base of the blank as their resting surfaces and shaping the sides via the process of creating the convex triangular curves. Unusually, the underside was deeply dished between the feet with the effect of letting light underneath to create lift of the box and visual separation of the feet.

The likelihood is that this will be written up as a project plan for our website so greater detail is expected in due course along with drawings to illustrate the finer points. This project does flag the benefits of precision planning and that there are endless permutations in woodturning to be explored and experimented with.

Material

Grain can enhance the result.
Plain straight grain needs to be given a lift just as too much figure has its own difficulties. Material of choice Macrocarpa as it is stable and grain lends itself to natural wood colour or dyes.
90 x 90 x 110mm, ideally has faces at right angles.

1.      Square off ends and turn a 48mm x 10mm spigot on both ends and take off square edges thus reducing chance of splintering off and cuts i.e. just a radius.

2.      Lock and mark middle point between spigots and decide which will be the lid and which will be the box based on grain and mark accordingly.

3.      Cut through using the Bandsaw. You now have 2 pieces      
a.      The Lid
b.      The Box

Mount the Box in the 50mm chuck and square off face.

1.      The rough shape of the base of the apple the curve begins about 20% down from the squared off face and end at the spigot.

2.      Cut the tenon approximately 4mm in from the outside edge using the Parting Tool to a depth of 6mm approx.  Start the internal wall so overall thickness is roughly 10mm.

3.      Hollow out using 10mm Bowl Gouges (35 and 55), Hollowing Tools and Scrappers assist. Check the depth, you must not go into the spigot. Sand and finish inside and apply sanding sealer.

Mount the Lid in the 50mm chuck and square off face.

1.      The rough shape of the top of the apple the curve begins about 20% down from the squared off face and end at the spigot.

2.      Mark the size of the diameter of the tenon using dividers.

3.      Carefully cut the mortise to a depth of approximately 4mm using the Parting Tool to a depth that will allow you to check the box fit(Tenon is 6mm). Check fit often. Not too tight – you cannot put wood back. Start the internal wall so overall thickness is roughly 10mm

4.      Hollow out using 10mm Bowl Gouges (35 and 55), Hollowing Tools and Scrappers assist. Sand inside and apply sanding sealer.

Mount the Box in the 50mm chuck using expansion mode

1.      The rough shape of the base of the apple the curve begins about 20% down from the squared off face down removing the spigot to an acceptable diameter for the base of the fruit(40mm) then turn in to create the hollow at the base of a fruit.

2.      Sand and finish

Mount the Lid in the 50mm chuck and square off face.

1.      The rough shape of the top of the apple the curve begins about 20% down from the squared off face down removing the spigot to an acceptable diameter for the top of the fruit(50mm) then turn in to create the hollow but leave a 5mm spigot to create the stalk of a fruit. You can use an actual stalk.

2.      Shape stalk, sand and finish.

Tonight Bruce demonstrated how to make a lidded box out of an old lawn bowls.

The first “obvious” advice was to make sure that the bowl is made of wood rather than a plastic one!

To initially mount the bowl, one of the existing rings (after cleaning it out) is used with a fitting chuck and with a padded jig on the tailstock. A spigot is the turned and the diameter is reduced/shaped on the tailstock side. This will be the bottom of the box.

The bowl is then mounted with the spigot. The outside of the lid is then shaped and while parting it off a tenon is formed.

Starting with a Forstner bit, the box is hollowed out partly. The lid is then fitted onto the box and once the connection is shaped it is finished (including sanding, sealing, wax, lacquer, etc.). At this point, Bruce showed how effectively oil-sand which eliminated dust and keeps the sanding paper unclogged for longer.

The box is then fully hollowed out and finished.

The box is then turned around and the bottom is shaped and finished. With sufficient care some of the original features and decorations of the bowl can be kept near the base to enhance the box.

Finally the lid is mounted (while protected with tape) and the inside of it is finished.

Thanks Bruce for the entertaining demo and the advice which can be used in any turning project.

Wig stand to a Christmas gift: a matter of measurement.

A Christmas miracle was performed by Lindsay in front of a very attentive and interactive audience. Lindsay was able to turn a wig stand into a coffee cup holder. This tree like cupholder was developed using two important measurement systems imperial and metric.

In short this demonstration could be called a struggle of imperial versus metric measurement systems for gift construction. Lindsay was able to have the use of tech features magic box in the production of this work and the associated gifts. A central direction was to use recycled wood measured primarily in the imperial system. The writer supposes that this was because of the use of recycled Kauri.

Measurement system: was used to determine the size of the base, the joining spigots, and the vertical stand in the coffee holder pegs. This is achieved through a concise use of the imperial measurement system so that the hanging cups did not neither touch the ground nor bump into each other.

Drilling onto square piece made the formation of the cupholders pegs accurate and facing in the correct direction. A process that gained the audience approval and raise comment of rounding off the square piece. Rounding off was a mixture of spindle roughing gouge and skew. Sanding was simple with the finish either being lacquer or paint. Positive thing about Lindsay’s processes is that the mechanisms for finishing was simple and lathe based i.e. the Jacobs chuck and the sanding mandrels. The writer was not sure whether these were measured in imperial or metric. There were some extensive audience discussion as to the exacting system of measurements. This is particularly applied to the formation of the cup holder pegs made from 10 mm (metric measurement) dowel.

Coffee cup pegs: Lindsay did mention that there are a number of methods for getting dowel down to the size, understood to be 9.25 mm (metric measurement). There was mention of Mac’s sharpened spanner system. However the more accurate measuring persons within the audience felt that this was difficult to maintain a measurement such as 9.25 mm measurements.

Lindsay’s application method allowed for slight inconsistencies in measurement by the use of a 12 ounce (imperial measurement) hammer i.e. hammering it in.

Gift two: The associated gifts were made with very similar precision. The advantage of being that the prime piece for the base of gift one: a mouse, was variable. There was a question raised in the audience as to whether this was imperial variability or metric variability. Lindsay resolved this issue by making one body and imperial and another body and metric. The writer is unsure which was which. Small important notes were; sealing the mouse before making holes for the ears and whiskers and tail. Ensuring that the hole for these items was of sufficient size in this case 3.5 mm (metric measurement) and the use of superglue to finalise the attachment.

Gift three: a mouse on a door wedge. Lindsay used his magic box and showed how the flat surface of the mouse can be dowelled to the angled surface of the wedge. Lindsay did comment that the angle of the wedge is up to the maker and the size of the piece of wood been used. However he did indicate that this could be done in either imperial or metric.

Gift four: Raupo rush poles. A garden implement that can be made in both measurement systems. The steel rods can be purchased and cut source of required. Lindsay did note it is important to drill the bass part of the Raupo rush to the same size of the rod. Again in this case it was a metric measurement is that with the style of the steel rod purchased.

A warning: when using recycled timber particularly Kauri recycled timber, check for nails. They do significant damage to nicely sharpen tools.

Happy Christmas

Demo by: Dick Veitch
Report by: Judith Langley

Yes, HO! HO! HO! our very own Father Christmas decked out in green with a beautifully groomed white beard, entertained us to a variety of tricks from the rimu ‘magic’ box, and a very skilful demonstration of how to make an seven segmented bauble.

None other, than our Dick Veitch. As can always be expected Dick lines up the lathe using the aculine and then quotes numerous dimensions and degrees and produces slithers of wood from the magic box. The secret to a successful outcome for this project is accuracy. A piece of machined rimu with straight grain and perfectly squared was the fore runner, and as demonstrated even a small variance in the component sizing could spell disaster.

A barrage of tapping and banging from inside the box brought about a red jacketed Father Christmas with white flowing beard, who took up his stance on the end of a piece of pre-war telephone wire jammed into a purpose made blank. He was followed closely by Mother Christmas with long bushy white hair, who met the same fate – left dangling from another piece of wire.

Dick continued his demo insisting that great care was needed when shaping the inside of the bauble, using tiny cuts and very sharp tools. One tip during the sanding process was to use a bobbin sanding spool to sand around the curves.

More tapping and banging from the magic box and out came staged and completed baubles – an elf, a fairy, and then a beautiful little bird house plus a narrated story of the Christmas tree. All taking up a position on the display block.

Finally, a finial was turned on the base of the demo bauble and a suitable top bead and eyelet on the top.

Dick is an accomplished demonstrator and this was a great and entertaining evening. Remember the miniature tool kit from Woodcut Tools which was used by Dick during the demo – available from Timberly and would make a very necessary Christmas present.

The linked plan gives all the dimensions and instructions on how to make this bauble without duplicating them in this report.

Project Sheet – Christmas Tree Bauble

Merry Christmas to you all.

Report by Bill Alden

Ian used the project sheet on our website. Which can be downloaded and printed at https://sawg.org.nz/sawg/wp-content/uploads/2011/09/Christmas-Tree-Snowman.pdf.

He started with some 40X40mm softwood 70 mm long and rounded it to 30mm. The drawing on the project sheet is a slightly smaller scale but can be used as a guide to mark where the hat, head, scarf and the rest of the body lines go. He then made v cuts on these marks and proceeded to shape the parts as per the diagram. A minimal amount of sanding is all that is required as the item will be painted.

Next he turned the nose from 10 mm dowel inserted into a 25 mm long nosed chuck to the shape of a carrot approx. 10 mm long.

The dowel was pulled further out from the chuck and the scarf ends were then turned to the shape on the drawing again about 10 mm long. This piece when parted off was then split with a Stanley knife. The flat side may need to be sanded flat.

The rest of the dowel was used to make 2 arms approx. 20 mm long shaping a hand and when complete sand a flat to adhere to the sides of the snowman. The top of the hat and the base can be sanded on a mandrel attached to the lathe, use a chuck for the bigger ones and a Jacobs chuck with a mandrel for the smaller pieces

Next comes the painting and miraculously a white snowman appeared. Ian suggested using Gesso which is an Acrylic Primer, and is quick drying and formulated to take ordinary artists acrylic paints.

Colour of hat gloves and scarf is up to you but the colour ways on the plan look good. The plan suggests hot melt glue for assembly.

Ian then prepared another blank and used a 5mm offset at the hat end and a 10 mm offset at the base. This allowed him to turn a hat at a raked angle. It was however decided that slightly less of an offset and allowing more length to the piece would make the job easier.

The body parts were then turned as before after the blank was re-centred. He then showed us some other variations including one with a cap instead of a top hat.
