An interesting project from the SAWG file. The possibly could be called the measurement way as there is a frequent requirement for measuring and checking. A spherical project can be made from any piece of wood that has good clean grain. Perhaps we should call it a spherical measurement project.

Good project notes to follow. All the pieces made from wood including little rattle bits. The three little spheres, designed to make a rattling noise without too much rattling. Dick called this baby Rattle: a grandparent friendly noisemaker.

Dick emphasised that a 50mm square piece is important. The length is variable. The object of manually splitting the wood is to ensure a solid basis for re-joining after the hollowing. And, offer a little bit extra of a challenge. Also, the irregular face reminds the Woodturner of which way is up and encourages more accurate measurement.

The making of the templates is well described in the project sheet. Their accuracy is important to the re-gluing and completion of the enclosed hemisphere. The templates allow a lightning of the rattle weight and increase the brightness of the rattling noise.

A good little joke was to remind persons that the beads have to be put inside the sphere prior to re-joining the pieces. One bright spark did mention that leaving out the little rattle beads would make it a lot more silent to operate.

Tip: Dick mentioned that one of the difficulties of this particular process was showing at the glue did not leak into the sphere and stick to the rattle beads. A number of options were shown with a key point been gentle and easy and consider extra glue after the primary gluing has been finished.

Another tip was to ensure that the finishing did not leaked into the inside and make the beads more muffled. A good point to remember wasn’t that in addition to the handle having to fit grandparents, there has to be scope therefore children who eat baby rattles. Dick showed some simple coving to highlight the handle and leave bits to grip on.

Therefore following the project sheet, making good templates and rechecking measurements produces:

Baby Rattle (Split) – Project Sheet

A quiet little grandparent friendly rattle.

Holm gave us a demo on making some charming looking birds with wonderful eyes. The bird body and head are turned from two pieces of wood and the eyes from another two pieces.

The eye was made from two pieces of wood approx 50mm long. Cut a black or darker than other wood used for the body; to a 10mm dowel shape. Now with a light coloured wood at least 15mm in diameter, drill a hole length ways and insert the dark wood dowel. Now turn the whole piece off centre so the dark wood shows on one side.

The head was turned from a 40mm square piece of wood 100mm long. The beak was formed 45mm long with the widest part 12mm. The head then formed 40mm wide. Holm used a metal pipe to shape the final round of the head.

To insert the eye drill a hole each side of the birds head, half way in line with the upper beak. The eye and hole only have to be about 3mm long/deep. Glue in place.

The body was turned from a 70mm square piece of wood 95mm long.

This was turned in a curved shape with a 25mm wide recess (divot) at each end. The recess big enough to hold the curve of the head.

Janet began the evening by handing around a number of jewellery items and explaining the various threads available on the market for threading beads. Janet typically uses 1mm thread through a 2mm hole. Do not use leather thread for bracelets. A huge variety of bead shapes, sizes, and colours are available at Dave’s Emporium in Manukau. Glass, Wood, Plastic are all on offer but it was recommended that glass was preferable over plastic as they look better and it’s all about the final look of the bracelet that sells the item.

Janet is very focused on marketing – identify your market – find your market – make things that your chosen market wants. Targeting the ‘sustainable brigade’ – the modern day hippy – the environmentally aware greenies – the people who only buy NZ Made and natural products. Most bracelets sell for $40 – $50 and when made from NZ wood they are particularly sought after.

Plain glass beads can be decorated with acrylic paint, wooden pieces can be decorated with pyrography, carved, bored and daubed with paint. Shells are often threaded amongst other items.

An extra fine scribing pen was passed around members. This is used for tracing artwork onto items to be decorated. The clearer the traced print the easier it is to pyrography.

Mounted on the lathe was a pre-prepared cylinder of wood (preferably hard wood)– about 100mm depending on the size of the bangle you are turning. This must be able to slip over the persons’ hand but not fall off under normal activities. Janet’s ‘go to’ chisel is the parting tool and the majority of this work is done with this tool. The tool is driven into the end grain after allowing the desired width of the bangle. Cut leaving no ridges on the bangle side as this will be the inside (nearest skin) and can be difficult to hand sand if too many ridges are left. When the desired width is achieved the bangle is parted off.

This piece can then be cut into about 7 parts which make the curved disks used for bracelets. Discussion arose over various methods of simplifying the project, more especially avoiding breakout when 2mm holes are drilled for attaching the 1mm thread to the disks. The solution to this was to drill the holes prior to turning the initial bangle, strapping the pieces with tape prior to drilling, and varieties of ideas. Janet handed around about 20 different examples of her work and challenged everyone to try their hand at making jewellery.

Finally, we were introduced to the ‘tree of life’ – engraved on pieces of branch, large round disks, in fact anything at all, and decorated with carving, pyrography, highlighted with copper powder, gold leaf etc. Kauri pendants carved to compliment an attached sea shell would get you another $5. This was a good return on a free sea shell!!

Overall this was a very interesting and well prepared demonstration. We left with no doubts that there were no limits to woodturning, no limits to one’s imagination, and that establishing and targeting a market was all part of the craft.

For this demo, our members showed off all manner of jigs and tools that they had created throughout the years.

Bob’s Jigs

1. A ply faceplate mount with concentric circles, allowing you to easily centre your plate or bowl (especially helpful if you have forgotten to mark the centre of the bottom of your bowl). Made of ply with 60mm chuck bite.
2. Toothbrush shaped sanding stick. Sanding grit attached via velcro pad. For reaching into tight corners and awkward hard to reach spots.

Graham’s Jigs

1. Velcro backed pieces of ply with curves.
2. Velcro backed sanding blocks
3. Sanding blocks of various sizes

Terry’s Jigs

1. Steadying Jig made from MDF, with skateboard wheels. Good for use on peppermills.
2. Disk with holes in it for platters. All the holes help with indexing, helping with easy dividing for carving/embelishments.

Bruce Jig’s

1. Bruce’s steady. A latch in the bottom allows you to detach one side. This which allows you to remove steady, without having to remove your workpiece. Make from industrial formica. Rollerskate wheels have been turned for accuracy.
2. Sandpaper cutter for dividing sandpaper into 8 equal sized pieces quickly. Uses a hacksaw blade. Note to write grit type of back of sandpaper before dividing.
3. Stainless steel tubes, sharpened at end to punch out sandpaper rounds quickly. Sharpened with an angle grinder.

Dick’s Big Steady

1. Battleship sized, made from steel. Can fit very large diameter pieces.

Jim’s Steady

Wheels from a pulley off a wardrobe fitting. Small wheels allow you to get right down to a very tight circle.

Teles’s Jigs

1. Jig for cutting wood at the same angle to create segmented rings. Can adjust angle.
2. Jig for cutting taper on table legs.

Dave Gillard’s Jigs

1. Faceplate mount with raised sections covered in rubber form. Used for holding warped bowls.
2. Grinding bit
3. Plugs for fitting over steb centres to help hold your workpiece.
4. Sanding bows of various sizes. Useful for sanding flat/high spots on hollow forms to get the perfect curve. Made from oak.

Cam’s “Squashed bottle”Jig

1. Jig for turning a “squashed bottle” vase of Cam’s own design. Designed to put a section of wood on either side, which when turned down, will form the sides of your “squashed bottle”. Removes the need for counterweights.

Photo of large experimental “Squashed bottle” Vase which didn’t end to well, but thankfully injury was narrowly avoided.

John’s tail stock support

Nova live centre used. A threaded 2ft rod (From Steel masters in penrose) can be inserted. 2Ft rod can be cut up for more versitility than a simple short bolt. Assorted items (lids, bottle tops) can be fitted into the end that will fit up against the workpiece.

Jim’s improvised push stick

An old style wood plane is used. Strip of wood attached to bottom. It can then be used to push wood through a buzzer/planer, keeping fingers out of harms way.

Jacques Drum Sander

Home built drum sander for lathe. Velcro backed sandpaper fitted. Many iterations. Small car jack fitted inside which adjusts thickness. Wood must be firmly held onto or can be sucked through and shot out the back.

The 24th June 2020 Bruce Wood gave a great Demonstration of an Offset Box. Bruce followed the project sheet in our website of a project Guilio Marcolongo is well known for. So in this report I will not reinvent the wheel by giving you the box instructions, but leave a link to the website project instructions. https://sawg.org.nz/sawg/wp-content/uploads/2020/03/Guilios-Burl-Top-Box.pdf

But in among the demo Bruce reminded us of lots of general woodturning things to help achieve a great look.

1. If you are using callipers for measuring wood; round off the ends of the metal pincers slightly so the tips don’t grab the wood.

2. You can find a chart for suggested speeds for using a forstner bit on the lathe in our website: https://sawg.org.nz/sawg/wp-content/uploads/2019/04/Drill-Speed.pdf

3. Bruce showed us how he used his “Digital Tailstock/Drill Press Measurer”. You can follow the instructions here to make your own: https://sawg.org.nz/sawg/wp-content/uploads/2020/06/Tailstock-Measurer.pdfhttps://sawg.org.nz/sawg/wp-content/uploads/2020/06/Tailstock-Measurer.pdf

• Being the professional turner Bruce is, he showed us it must be ok to accidently drop 11 things on the floor during a demo.

• Bruce used a micro light that is attached to the tool rest which allowed him to see inside the box while turning and see exactly what he was doing. You can see the light here: https://www.woodgrainnz.com/apps/webstore/products/show/8148180?fbclid=IwAR0tBNT3iAbBAyB3gf11GQ8x5jE6_uaSmOttlzskJPE2aiPdnDV95coTnS4

• Use a fine wire brush on your sandpaper to unclog it and get more life from it.

Bruce used Ondina Oil to wipe over his turned wood just before sanding. This stopped a cloud of dust cloaking the front row of spectators. Read more about this oil here: http://www.timberlywoodturning.co.nz/products.php?product=Woodturners-Sanding-Oil-%7B47%7D-Shell-Ondina-Oil-15-%252d-1-litre-

When using buffing wheels on your lathe it is easy for your turned object to fly out of your hands. So Bruce laid a folded towel over the lathe bed, so if the object flew it would not get dented on the lathe bed.

Another fascinating demo by Warwick, choosing this time to make a lidded box from stone.

Inspired by a small Malachite bowl he had picked up on his travels through Russia, Warwick had made a few small boxes with stone inserts in the tops. Not fully satisfied, he decided to make a box entirely from stone.

Hence his demo of a lidded box from Oamaru stone, with resin/stone lid, finial and base.

Oamaru stone is a very soft, creamy white stone, with a hardness of 2 on the Mohs hardness scale. (Diamonds by comparison, have a hardness of 9, while fingernails have a hardness of 2.5).

Warwick started with a square blank of the white stone. The corners were chopped off with a cheap saw from Bunnings. A hole was drilled in the top, so it could be mounted onto a set of pin jaws. The outside of the box would be shaped first.

A cup chuck was used on the tail stock to help steady the piece. (A steb centre or piece of wood could also be used as an alternative, to help hold it in place)

Thin pieces of rubber were used on both sides of the stone, to help hold the slippery stone in place. Foam rubber can also be used in the jaws to help prevent cracking.

The stone was turned at a slow speed, and normal woodturning gouges were used. Containers were placed under the lathe to collect the dust, which would be used later for the lid.

Large plumes of dust were created, which according to Warwick is “good to breathe in” (???). He went on to claim returning soldiers from WWI (Or WWII?) would be sent to work in the Oamaru mines, and the dust would help “neutralise the poison in their lungs”. Some interesting history from Warwick…

Once the outside shape was achieved, a light sand of 100 grit paper was enough to smoothe it out. Before turning it around, a forstner bit was used in the tail stock to drill a hole in the bottom of the box.

The box was turned around and remounted. A long thin centre of Warwicks own creation was brought up in the tail stock for additional support. The top rim was then shaped to receive a lid and the inside hollowed out.

Tile grout sealer was sprayed on the outside to seal the stone, preventing dust from coming off and to avoid staining the white surface.

For the top, a kitchen sieve was used to sift out the fine powder. To this was added colouring (artificial rock), and then clear resin. Three separate batches of the coloured rock/resin mixes were made. One for the top. A second for the finial, and a third for the base.

These were set in a shallow bath of ice water to keep them cool while the resin set. As these would normally take many hours to set, Warwick had some of these pre-prepared blanks made in advance.

The lid was mounted in a 50mm chuck. This was an easier material to work with, although the sanding resin can be harmful to your health. Warwick had an answer to this, which was to use wet sandpaper to prevent dust, creating a better finish and to help cool it down. After he had turned the shape he wanted, he began the long sanding process. From 120 grit up to 600, then micro mesh pads up to 2000 grit. EEE was used, followed by carwax polish.

The bottom is created in the same way, and both are affixed to the stone with clear silicone glue.

The final product was very impressive, as were his previous efforts which he displayed.

Warwick did a further brief demo in turning a “greenstone” lid. For this he mixed some Jade powder he had purchased, with resin in a 50:50 mix. If there is not enough resin in it, it becomes too hard to turn. While this material is tough on the chisels, it scrapes well. Sanding is done with Carborundum sandpaper, which has a hardness factor of 8. Slightly higher than the greenstone hardness, which is seven.

He exhibited an impressive lidded box he had made with it, with a brass insert and malachite pebbles inlaid.

Some in the crowd were disappointed it wasn’t a hunk of pure greenstone, but Warwick told them he would need diamond edged chisels for that!

Thank you Warwick for another fantastic demo!

 Terry had pre-poured the pewter into grooves in timber to make rods; easier to work with.

Pewter turns like butter but will scratch easily.

2nd hand pewter from op shops melted down can be ok, but old stuff will contain lead, whereas it is no longer added to new pewter.

Making the base- Use a forstner bit in plywood to make a round mold.

Pewter has a low melting point, a solder iron is no-good however.

Rim – groove with rebate; measure your outside perimeter on blank.

For molten pewter, jimmy a metal spoon onto a long stick, stir to remove slag. If left in will make the pewter brittle from air voids. It will stop skimming off slag when it’s ready.

Pour into base mold and rim, Keep continuous even pouring till it crests.

Running it under cold water will weaken it so allow it to cool naturally.

When melting do not let it boil. It will burn the timber and will react with resin in the wood when poured directly into your bowl. Sparks and flames ensue.

Diluted pewter containing lead will also make flames.

To release from mold, sometimes sawing of the wood will be needed.

Terry demonstrates turning a bowl, cutting spigot (54mm), proceeds to make the mess he promised not to (10/10).

For base, cut rebate for pewter to key onto, 3mm, not too deep so you don’t lose the bottom from the inside.

Remove from chuck.

‘New turners can’t imagine a concave curve’, isn’t that always the way.

Plywood backer behind the pewter base disc in the chuck.

Levels pewter, knocks over his shavings bowl.

Cut corresponding rebate in pewter.

Turning the tenon, flat or slightly concave is ok.

Turning the rim, add spigot. Chattering that can be heard is the pewter moving in the mold, can use superglue to hold it.

Check rebate depth is the same on both sides.

Back to bowl. To avoid going back-and-forth buy a second lathe (but only from Terry of course).

Match rim to bowl with calipers.

To glue use 24hr araldite  , quicker setting (5 min) is ok to get turning sooner but not as strong.

Use tape on the chuck to avoid gluing the jaws shut (Terry has extras of course).

Turn away wood on top to reveal Pewter rim, round and tidy.

Pewter embellishes nicely, a leather punch will work and can accent with Indian ink in the grooves.

Terry uses a texturing tool.

For sanding, 400 through to 2000.

Don’t use Danish oil- black comes off pewter into the wood.

Turning inside of bowl, finish rim first because the heat from the glue can move it.

Sand inside w/ 240 grit, through to 400.

Use jam chuck to reverse bowl, Terry uses next bowl to hold it however, turn RPM down.

Cleaning the base pewter, pronounce concave of the base to remove weight.

Tidy and sanding exterior of the bowl.

Warned to use mask with mahogany as the dust is sharp and dangerous to inhale.

The base foot pewter can scratch easy but won’t need polishing like silver.

Completed.

An excellent demonstration highlighting the need to work through process and sticking to measurements, measuring again and checking that measurement. Dick Veitch followed the Project Sheet for this small functional item, with several components.

As usual Dick came up with some simple solutions, some quick marking answers and developed a fun project. A good chance for new turners to think through process, work out the operation off the plan and apply the required actions. A good example was the use of the Bryden centre finding tool.

The side title to this project could actually be the drilling project and/or Jacobs chuck use. The Turner is required to use the Vernier callipers and check the diameter of the Forstner and/or Brad point drill bits. This included the simple straightforward sharpening of the Forstner cutting blade. The age-old question of checking out your tools before use was quite apparent. It may be a 16 mm Forstner bit, however, when check the diameter was 15.85 mm. A small discrepancy that could totally fail up the pop-up movement.

Dick demonstrated that keeping to the sequence was key to this little project. Possibly one should say sequence and correct depth. Marking the depth on the drill bits was a good value-added action. Simple, straightforward and easy to do with a bit of tape. There was a timely reminder that dual speed is important. Check the charts. Ensure that the shavings are coming off an even basis. The correct speed means cutting rather than skidding.

Although a functional item, once the components were completed, there was plenty of design space for getting the best looking form. Choosing the appropriate type of wood will help get clean fine-grained services that allow the pop-up mechanism to work.

A good learning project.
The project sheet is on the SAWG site and is easy to follow. Further, provides a good plan reading and/or process organisation exercise.
