This Wednesday Colin Wise demonstrated the creation of a three-cornered bowl with upward-pointing wings, after showing us a number of other ways to use a cube of wood. These examples included several hollowed boxes with a variety of openings and included shapes, and an amazing tower of graduated thin-walled cylinders, resting on a cube from which these cylinders were cut by bandsaw.

To create the winged bowl, Colin mounted two opposite corners of a cube between centres, pressing the cube between the headstock spindle and tailstock cup. When spinning the cube, we saw separate points created by two sets of three corners.

With the lathe running at about 1000 rpm, Colin turned away the set of three corners nearest the tailstock to create and finish the external surface of the bowl, as well as a spigot at the tailstock end. After removing waste beyond the spigot, he reversed the workpiece to hold it with a 50mm chuck.

He then turned away the wood that was now at the tailstock side of the three points, creating three wings. When the spindle of waste between the points and the tailstock became thin enough, Colin knocked it off and then turned the inside of the bowl at higher speed (about 1400 rpm) using a cup tool , thinning the wings at the same time.

Interior sanding required care given the risk created by three points spinning around; Colin suggested shaping a curved wood-and-Velcro sandpaper holder to reach into the bowl while keeping the fingers safe. He used a sanding block to smooth the flat wing surfaces.

Colin pointed out the tearout that is inevitable in turning a cross-grained bowl, and suggested using sanding sealer during the final cuts, to minimise this. He then described finishing the outside and the foot with the bowl held between centres using cushioning at the headstock end to protect the inside surface.

Throughout, Colin repeatedly emphasised the need to check the alignment each time the workpiece was reversed, to ensure the bowl remained perfectly balanced. He agreed with members’ suggestion that the order of events could be modified to create a similar bowl with the corners of the rim pointing down instead of up.

Thanks, Colin, for a demo that was carefully planned and brilliantly executed.

The term project for the guild members is to produce an item from a 125mm cube but true to past form Dick was not content with producing 1 item he made 6.

The block of wood was 125 x 125 x125mm Kahikatea (Dacrycarpus dacrydioides) White Pine. In addition to the block of wood Dick had a block that was cut into 9 pieces 41x41x125mm, give or take a fraction, and his Magic Box and wand. The pieces are held by the square end for spindle turning, long grain.

1.  BALL AND CUP TOY as per that in the Club projects.

The piece was held in the chuck with a Steb live centre in the tail stock, a practice used in all of the 6 demonstrations, whilst using the roughing gouge to round and roughly shape. The tail stock was removed to ease finishing with either a spindle gouge and/or skew. None of the pieces were sanded as Dick’s skill and technique resulted in clean surfaces.

The initial roughing process didn’t go without incident. The piece was not securely locked in the chuck and went walk about. Once back on the lathe and back on track the ball, 10mm in diameter was put in the Magic Box followed by the Cup. The Box was tapped with the wand and low and behold the finished toy, complete with ball attached with string was revealed.

2.   SANTA TREE DECORATION or was it a selfie? It is also as per that in the Club Projects.

This time Dick demonstrated that by putting masking tape on the tool rest and marking where the cuts were to be made saved time.

Once the Santa was finished it was parted off, close to the chuck, cutting a slight concave in the base. The Santa went into the Magic Box and tapped with the wand and low and behold the finished Santa, complete with beard and red and white clothing was revealed

3.  CHRISTMAS TREE.

The cone shape was roughly formed with the roughing gouge. With the tail stock removed Dick proceeded to cut 4 cones with the skew, with each getting wider, as he worked from the top of the tree toward the chuck. Care needs to be taken as the initial cuts forming the sides of the cone are not supporting the bevel.

After the cones are cut a trunk is formed with the parting tool and a base made. The Christmas was finished and parted off, close to the chuck, cutting a slight concave in the base. It too went into the Magic Box and tapped with the wand and low and behold the finished green tree was revealed.

4. A real challenge –  TEA LIGHT DECORATION using 4 of the pieces together for Inside Out Turning.

The key to the success of this is all 4 pieces being dimensionally equal.

In Dick’s demo the pieces are not glued but held, as a “block”, 80×80(indicative) in place between 2 chucks. This requires a live centre in the tail stock for 1 of the 100mm chucks. The wood between the chuck faces is divided roughly into 3. Mark all 4 faces with the lines so they can be clearly seen when the piece is turning.

An alternative to using 2 chucks is to use hotmelt glue on the ends only, firstly joining 2 pieces to form 1 of 80 x 40mm then join these, again with hotmelt on ends only. Carry this process out using the flat surface of your lathe bed. Wrap duck-tape around the glued ends and turn using spur drive and live centre.

Round the centre 3rd and ensure the sides are square.
Cut cove with a deep vee in the centre but don’t go too deep as you need strength for when you are turning the outside. Sand and finish.

Separate the pieces and reassemble so cove is on the inside and permanently glue. Keep glue away from inside so when assembled glue is not squeezed onto finished surface. (If using alternative method of spur drive and live centre turn a chuck bite and remount into scroll chuck.)

Remount and turn the outside to the desires profile. It too went into the Magic Box and tapped with the wand and low and behold the finished decoration complete with Tea light was revealed.

5. HONEY DIPPER as per that in the Club Projects.

Considered by most to be the most useless addition to your cutlery draw was put in the Magic Box and tapped with the wand and low and behold the finished item.

6. The final demonstration had us all wondering “What the Hell”.

This time, after roughing down to a round, Dick demonstrated that by putting masking tape on the tool rest and marking where the cuts were to be made. From the tail stock end and the measurements were 15,10, 15, 25.

The 15mm section was reduced to 6mm diameter and parted off and put into the Magic Box;
The 10mm section was reduced to 9mm diameter and parted off and put into the Magic Box;
The 15mm section was turned into a sphere and the 25mm section was turned into a cylinder then parted off and put into the Magic Box;

The remaining wood was hollowed to a depth of 23mm with a flat bottom and straight sides. The mouth was rounded with a bead produced on the outside lip.

A stem, like found on a wine goblet, complete with base was formed and parted off, close to the chuck, cutting a slight concave in the base. “It then went to the bandsaw” then into the Magic Box and tapped with the wand and low and behold the finished item – a doll, complete with hair courtesy of Dick’s dog, sitting in a chair was revealed.

A challenging demo if ever there was one.

The term project for the guild members is to produce an item from a 125mm cube. Terry proceeded to show those in attendance how to make a winged lidded box from a 125mm cube of matai, which one of the hawk eyed observers caused Terry to admit that his cube was in fact only 122.5mm. That is not a bad observation from about 3m away, but it was typical of the fine repartee that took place during a most informative and entertaining demonstration.

As is usual with Terry’s demonstrations there were lots of tips and helpful hints e.g.

• Turn the cube cross grain
• Make sure that when centering the cube for a screw chuck, that you get the exact centre. Terry use a Stanley knife to mark the centre, then a centre punch finishing with a smack on the handle of a Phillips screw driver on the centre spot to ensure that when you drill the screw chuck hole the drill does not wander due to the grain
• Sharp tools are essential, when the chisel starts to feel dull; a couple of quick swipes on the CBN wheel will bring it back to sharp again.
• Use finger nail ground bowl gouges. Terry’s preference is to grind the tip so that the wings are swept back. Use 35deg and 55deg gouges.
• Hold the chisel handle in a lowered position, rub the bevel and then raise the handle until it begins to cut cleanly.
• Use negative rake scrapers; they are much more forgiving than the traditional grind.
• Keep your eye out for any early 20th century paino’s left on the side of the road for the inorganic collections. If you spot one, grab the black keys, they will be ebony. Great for making small finials. You might spot the odd ebony ornament on Trademe as well.
• Be careful how thin you make the wings, they may need support with bracing and hot melt glue, depending on the thinness and the sort of timber you use.

Terry finished the winged lidded box by adding some embellishment with his famous $10 texture tool which of course doesn’t cost $10, but adds $10 value to your work each time it is used. Well, that is what Terry reckons and he would be right!

This Wednesday we had demonstrator John Basillie from Franklin show us how to make small wooden owls. John has been woodturning at Franklin for 6-7 years and Wednesday was his second visit to SAWG. It was a very interesting and intricate demo which provided some tips (and some longcuts) for turners of all skill levels!

Making the pupils:
John started out by making the pupils for the owl out of black rata which provided a nice contrast to the iris. Using a skew, he turned the pupil to a 10mm diameter with the help of a template. He then used a modified hacksaw blade to part the pupil off. John has found it easier if the pupils are made one at a time.

Making the eye:
John then proceeded to make the eye, he firstly drilled the hole for the pupil with a 10mm forstner bit and then the pupil was pushed in and glued, the eye was then turned down to 19mm in total.

The Body:
The body for the owl was made out of a 55x85mm block of Swamp Kauri which was turned parallel to 48mm in diameter with the help of groves cut periodically along the block. The block also had a 20mm spigot which would be the base of the owl.
Next John divided the block into 4 by drawing lines 12mm wide. These were used as guides to create a sphere.
Firstly, he cut from the end of the block and the first 12mm line on the block. He the cut from the centre line to the end of the block.

Despite the decent sphere which was produced Johns ended up adopting the quote “What you lack in skill you make up with a bit of brute force and sandpaper” and he proceeded to grind the ‘sphere’ down to a sphere using a cut steel pipe, it was then finished off with ondina oil and sand paper.

Finishing the body:
Using a reverse chuck John put the body of the owl on the tail stock and then pushed it up to a jamb chuck he had made out of ply wood and MDF; this ensured that the body was centred. The reverse chuck was the removed and the base of the owl was cleaned up and made slightly concave.

Making the owl:
To make the eyes John put the body on a flat surface in order to decide where he thought the eyes should go. He generally follows these measurements: eyes 33mm up from the base and 20mm apart from the centre of each eye.
The body was then put back into the jamb chuck and it was lined up using the tail stock. To make the hole for the eye John used a forstner bit after enlarging the hole with a centring bit. John then used tight bond PVA glue to secure the eye and it was the turned down flat against the body. This process was repeated for each eye.

Thanks to John for the great demo! This owl it is a sweet looking creature made for the purpose of holding or for looking at on your desk. The above process was fairly involved but could be made simpler by using a few short cuts… such as using a sanding belt for the base. Overall, I wish John all the best on his mission to create an army of owls!

Report for 25 July 2018

Jim was demonstrating how he makes his spiral candlestick holders. He usually makes them in pairs, with one having a left handed twist and one having a right handed twist.
 
He makes them in three sections, as this provides more convenient lengths to work with, and it is easier to keep the internal hole centralised in a shorter piece.
Selection of a good quality auger bit is also essential for a good result. The cheap auger bits with screw points at the front of them do not tend to cut very well, and can wander off centre when drilling the central hole.
 
Once you have a round piece of stock at the desired external diameter, select the section that you will do the spiral design on. Establish 6 parallel lines using the index on the lathe, and divide them into three sections. Now use a piece of flexible plastic with a straight edge to join the intersections of these lines on the angle. The accuracy of marking out is critical to ensure an even and equally spaced final product.
 
Using a V block or a square jig that matches the size of your workpiece (and a rod of the right internal diameter to reduce blowout on the back side of the holes), start drilling holes along the length of these marked out lines (using a stop block to get a round of perfectly lined up holes at each end.)
A ‘brad point’ or ’dowel’ drill bit is essential for this step, as the sharp central point on the drill bit ensures accuracy of the hole placement, and prevents the drill bit from wandering as you drill the holes. It also allows you to partially overlap each hole with the previous one to remove more material with the drilling stage and requires less work by hand at later stages.

 
The smaller designs have 72 holes drilled to make the starting point for the spirals, and larger designs can easily require hundreds of holes.
 
Once all the holes are drilled, start using a sharp bench chisel to remove the waste between holes and smooth out the spirals. Always work with / downhill on the grain, as this will greatly reduce the risk of taking too much material off and ruining all your hard work to this point.
The next step Jim uses is a microplane. He got a right-angled one and squashed it flat in the vice to provide a flat profile that allows him to get into the gaps between the spirals and continue shaping.
Once the planning is finished, the next step is sanding. Hand cut thin strips of sandpaper with tape added to the backing for extra stiffness are threaded through between the spirals and worked back and forth to sand the rounds on the inside of the spirals. Canvas backed sandpaper is also good for this (as is often found on belt sander belts etc)
 
The process can take many days of fine hand tool work, but the finished results can be quite spectacular.

Report for 27th June 2018
Report by: Dylan Budd

Ian started by regaling us with stories of his youth growing up on the farm, where he started making toys in the workshop from age 13.

He then went on to talk about some of the interesting works he has learnt how to do from attending symposiums over the years, and encouraged our members to attend all that they can. He considers the admission fee a small price to pay to see such a great collection of international demonstrators that it would otherwise cost thousands to see.

Ian then pulled out a sample of the wave bowl that he was going to show us how to produce, as well as a collection of other pieces that had been made utilising the same concepts and equipment. Some of these pieces also included the creative use of builders bog mixed with paint to fill voids instead of resin.

To start off the process he turns the outside of a bowl to the diameter of the widest (or furthest protruding) part of the finished piece. He would then turn the inside of the bowl, allowing a generous thickness to allow room to work (and to try again if you mess something up!). Once this is turned he placed a fillet of MDF inside the bowl to act as an alignment tool for reassembly, which was also marked to ensure the correct orientation for reassembly.

Ian then started showing us the jig he uses to cut the sections out of the bowl. With a square block of wood mounted in a large chuck on the jig, it seemed that half the audience understood what was being shown, and half the audience didn’t know what they were looking at or how this related to a wave bowl. The latter group included a very confused and exasperated Terry Scott, much to the amusement of all present. Once the square block was removed and the bowl put in place on the jig, the penny dropped and all present were on the same page.

Whilst Ian was demonstrating the wave bowl tonight, it is also clear that this jig could be used to cut wave patterns into almost anything, an example of which were some wooden bangles that had been produced from the same jig.

The jig consists of a base board clamped to the bandsaw table, with an L shaped piece of MDF mounted to the top of it. The base board and the base of the L shape have holes and a slot respectively to allow for indexing and pivoting in a circular motion, and the vertical of the L has a slot cut to enable a chuck to be mounted in it.

It is important to note that the pivot point holes in the base board must line up with the front of the teeth on the bandsaw blade, as this is the cutting point. This will allow for a safe and smooth radius cut in your workpiece.

Once the jig was set up Ian showed how he would take one radiused cut, advance the jig by the desired amount, and take another cut. This would determine the size of the fillets that would either be turned down further to form the bowl, or left at the current diameter to form the protruding waves.

You could also alter the orientation of the bowl in the chuck to achieve non-parallel waves. This introduces all sorts of possibilities for complex patterns and crossing waves. If you have a try with this technique it is important to remember that whatever material you remove (including the kerf of your saw cut), you must put this same thickness back in if you want to achieve different waves all matching up in a single piece. This could be achieved by inserting a veneer matching your saw blade kerf, or by cutting the inserted waves from a different material and allowing for this lost thickness.

Whilst there were no shavings flying this evening, it was an interesting and amusing demonstration for all present, and it will certainly inspire some new creative ideas from our members.
