A bowl with a decent bark

The best timber for this kind of bowl is any fruit tree, the flowering cherry tree, olive tree or any tree with not too thick bark. Pohutukawa is a good wood, but the bark is fragile.
The secret to capturing this natural-edged look is to turn the bowl from a piece of timber that has not yet totally dried out.

Water power on the up

The first water ram was patented in 1772 by Englishman John Whitehurst. Designs have evolved since then and continue to do so particularly in Holland where, in the 1990s, one university was building 20 water rams a year for third-world projects.

AC/DC: converting simply

There are times when you need DC (Direct Current) voltage for some project or other; it is mostly small applications—has to change the 230v AC mains into something else first, normally a low-voltage DC.

On fire!

Over the last couple of decades I have made my share of braziers, fire pits, and pizza ovens out of anything from old truck rims to LPG cylinders. But my hands-down favourite for source material for fire containers is CNG cylinders.

Making a violin – part two

Making a violin is a complex job involving around 40 pieces of wood of various types and sizes and plenty of patient, skilled woodworking. In Part One we chose the best maple for the back and spruce for the belly, shaped these plates and created the rib structure. Now it’s time to finish the construction.

Making a violin – Part One

When I decided to make a violin to take to a conference in America, I chose a beautiful example by Guarneri “del Gesu”—the “King” violin made in 1735—as a model.
Given the significance of the violins by the great makers, there is a respected tradition of making copies or instruments modelled on their work. I was quite happy for The Shed magazine to follow its progress but as there are books written in great detail about violin-making, this magazine article can only be a summary of what I did and some of the problems I encountered.

Industrial style at home

For the centre, I had intended to use one-inch (25.4 mm) diameter stainless steel that I had left over from a previous job but the lamp we purchased came with a one-inch chrome-plated tube which I decided to use. It also came with a screwed insert in the top for attaching the lamp and this saved me from needing to make an insert.
If you use stock tube, you will need to make an insert to fit in the top of the tube to take the lamp you purchase. This could be a nut you can find with the same thread as the lamp and where you just need to have the outside diameter reduced or you can make an insert and thread it accordingly.

An engine imagined

“The sound of that Pearse wing destroying itself in a matter of seconds as it tore itself apart in a chain reaction fashion on the 14th September in 2012 at Whenuapai Air Base is a sound that I don’t think any of us will forget for a long while.” Retired Air New Zealand captain, Neville Hay as test pilot was not apprehensive but noted, “You have to think about everything you do. You can’t rely on memory of flying the plane.”

Black oxide finish

The particular process we are looking at in this article does not effectively alter the dimensions of the part as it etches into the surface rather than deposits on top. Black oxide finish is sometimes called parkerizing and it is common on components such as gun barrels because it does not involve high enough temperatures to cause distortion and there is no dimensional change.
