Terry Scott – Pewter

Club Meeting: 10 June 2020
Report by: Rio Davies

 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.

Dick Veitch – Toothpick Holder

Club Meeting Demo : 3rd June 2020
Report by Graeme Mackay

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.

Tom Pearson – Lavender Bottle

Club Meeting: 18 March 2020
Report by: Bill Alden

Tom showed us various boxes that he had made over the years of many sizes. Including a spinning top box which was an ancient game originating in the Middle East

The blank used for the Lavender Bottle was 20mm X 20mm and 120mm long was placed between centres. Tom used a “story stick” with the dimensions of each element of the bottle. From the Headstock end. 60 mm for the bottle 15mm for the 8mm spigot plug and 20 mm for the knob.

Leaving the bulk of the base square he shaped the foot and the neck of the bottle with a bulb at the top. The next 15cms were parted down to 8mm using parting tool and calipers. The lid was then shaped as per the photograph with a spindle gouge reducing the waste at the top for later removal.

At this stage the bottle should be sanded and finished.

Hold the base in in a small set of jaws and centre using the steb centre. A 2 mm parting tool is now used to cut off the spigot. With an 8mm bit drill to a depth of about 25mm and fit the lid spigot into this hole . Tom used a round file and sandpaper to achieve a snug fit. It was noted that the spigot may be shaped more narrow where it meets the hole to assist fit. The lid can now be removed from the waste and final sanding and finishing done at this point. The spigot is sanded if necessary to ease the fit.

The base is now parted off and sanded on a sanding mandrel in a Jacobs chuck on the lathe or a belt sander. Finish with oil wax or lacquer as preferred.

When ready to sell or gift pour no more than 2-3 drops of oil in the hole. This will permeate through the wood to perfume handbags, drawer or car, etc. Too much lavender oil can be overpowering.

Tom sells these with a small bottle of lavender oil in an origami box made from Calendar pictures. For instructions see https://www.youtube.com/watch?v=U8_uUz5__nk

Marbling

By Dick Veitch

Despite marbling being a craft practised since the 12th century we still don’t have a precise recipe on how to do it. It has, however, been part of the NAW National Certificate in Woodturning since its inception. In the training books we find a recipe that works – but, it seems, not well enough for many to use marbling as a frequent enhancement of their woodturning.

When Walter Wager, from near Tallahassee, offered us a marbling demo I was a bit ho-hum. He included a copy of his marbling report to the American Woodturner journal. Nice pictures, nice work, and yet another recipe requiring the mixing of spoonsful of this with quarts of that to make up gallons – probably US gallons. There also was a statement about “pure” this and using distilled water. A little web search established that I could buy distilled water in the supermarket and I could order in pure methylcellulose and pure alum.

That suggestion of not using our chemical-laden town water and not using wallpaper paste (methylcellulose with unknown additives) made great sense. Please do visit us, Walter.

To prepare for his visit I worked my way through many recipes to make up an alum solution and the methylcellulose size needed to float the acrylic paint needed to create the marbled effects.
Now, bear in mind that there are marbling kits available in some New Zealand stores and online – they all work, but most are designed for one-person use. We were going to have ten, or more, people wanting to put marbling on their choice of wood. The National Certificate in Woodturning also needs to cater for more than the single user. So, getting information on the important ingredients is necessary.

The important wood preparation is firstly to choose a dense white wood, turn it, sand it, and apply alum to the wood – just keep the items small please? That meant that most arrived with eggs, egg cups, a wig stand foot and little bowls but, as always, one had to arrive with an item that challenged our biggest dipping dish!

Any acrylic art paint is supposed to work – true, most do – but, as a rule, the cheaper the paint the coarser the granules within the paint.

Next challenge is to get a nice pattern of paint floating on the surface of the methylcellulose size mixture. Amongst the crowd at Walter’s hands-on afternoon we had some fairly basic acrylics, tubes of quality colours and some of the Golden High Flow Acrylic mentioned above. Most of those had to be thinned with water (or, later, more paint added) so that the paint would float on the surface of the size. Some spread more readily than others. Some colours of the same brand spread well when used alone but then either would not spread when placed over other colours or would spread madly and push everything aside.

Our choice now is Golden High Flow Acrylic. Ok, appears to not be cheap but only a few drops are needed for each marbling action. This paint has a fine and consistent texture and is available in more than 50 colours.

Obviously, putting drops of colour sequentially at the centre of a bowl results in rings of colour. You can have these rings of colour on your wood or take a comb and stir it a little. Then dip the wood in. Rinse it off and let it dry. When thoroughly dry put a finish over it.

Dick Veitch – Spire Box

Club Meeting: Wednesday 19th February
Report by: Emma James-Ries

This week we were treated to a demo by the one and only Dick Veitch. He started off by talking about the latest Teknatool Nova Orion lathe, kindly loaned by Carba-Tec. Dick was very impressed with this version, asides from the secret Tailstock compartment which held centres. Otherwise, if you’re looking to upgrade your lathe, this model won’t disappoint.

Moving on to the nights project, Dick chose to turn a Spire Box, which was made with multi-centres. It is import to choose a strong grained wood for this project. Taking a piece of wood with dimensions 220mm long and 70mm square, mount on the lathe and round off to 60mm diameter. Once round, cut the curve of the outside of the foot of the box. Then cut a cove in the centre down to 51mm. Now part this cove down the middle and set the spire part aside. Dick then went on to hollow out the lid part of the top section of box. Setting that aside, he hollowed the bottom part of the box to fit the lid. It was at this point that Dick realised he needed to stand on a platform to properly hollow the box, as the new lathe was fractionally too high (it was on a small plinth). Always important to remember to be at the right height for turning to avoid unnecessary strains and pains.

After that was complete, he put both parts of the box together and remounted on the lathe, to recut the curve in the centre. Once cut down to 48mm, mark the centre points on each end. Dick then went on to explain that while making this project, he encountered problems when turning the shaft of the base and the finial on top. This was because the off set body of the box was too heavy for the shaft to bare once it was turned thin. To counteract this problem, Dick made a jam block that fitted neatly into the box to reduce the off-centre weight. Once counterweighted, go on to shape the stem with a spindle gouge. Dick made some lovely beads and wings under the box body and tapered the stem. He then showed us a clever way of sanding the underneath of the box with an electro file. Dick mentioned at this point, that it was wise to put a brace between the box and for to steady the stem when sanding as it is so fragile at this point.

Once Dick was done sanding the base, he went over to his special ‘magic box’ and pulled out one he’d made earlier. A fabulous project, thank you very much. This project sheet is available on the SAWG website under the name Spire Box.
