Man who gives a toss

21 March 2025

The incentive for the project came from Dave’s sons, Josh and Andrew. The boys were jumping their bikes and Josh (13) came up with the ultimate idea—throwing their bikes with a trebuchet which they had seen in action on computer games. The boys started with a small trebuchet using stones but it didn’t throw them far so dad got into the act. Dave checked out machines on the internet that were even throwing cars. The world record is a 630-metre throw. He was impressed and thought he would give it a go. He had some Lawsoniana trees he intended to drop so thought now was the time. He finds the Lawson trees were straight and the wood is very flexible.

Welding: Standing to attention

12 March 2025

I moved recently and in the haste to pack I loaded my lathe complete with its stand. The stand, which is really just a couple of sheet-metal cabinets, didn’t really survive the move all that well and it was bent out of shape.
That didn’t really bother me since I have wanted to make a decent stand for the lathe since I got it, and include some drawers for tooling and other bits and pieces. Now that the lathe is in its permanent home I have my chance. This is just a small lathe but it weighs 250kg nonetheless.
I wanted to make something sturdy and solid that would serve to support the lathe without sagging and eliminate any vibrations.

This could be good news for sheddies – but we must be quick!

Our parliament is currently considering a member’s Bill, drawn by ballot, called the ‘Right to Repair’ Bill. It’s due to go a Select Committee for consideration, and we can make submissions i.e. say what we think of it, before 3 April this year. It’s important because it will make spare parts and information for doing repairs far more readily available and this should slow the rate at which appliances, toys and so on, get sent to landfill.

The great Greek gear train

28 February 2025

Many years ago in a history of technology, I read a passing mention of a strange artefact, a piece of mechanical gearing, that was in the Athens National Archaeological Museum. I didn’t know then, but getting to see this would become an obsession in my life.
The artefact was recovered in 1900 from an ancient Greek galley. This ocean-floor wreck was accidentally discovered by sponge fishermen sheltering from a storm by the tiny island of Antikythera. One of the artefacts later taken from the ship was a corroded block of copper which, after it was cleaned, revealed the vestiges of a complex gear train. This has come to be known as the Antikythera Mechanism.

The Shed King is going to Bonneville, can you help get him there?

26 February 2025

“My name is Dave Alexander, and I am on a mission to set a land speed record of over 420 kph at the iconic Bonneville Salt Flats.
With decades of experience in motorsport dating back to the 1970s, I have had the honour of competing at Bonneville before, where we achieved three records in just one week with my home-built car from New Zealand.
My latest creation is an impressive 7-metre ‘Lakester’, engineered specifically for land-speed racing and powered by a turbocharged Nissan RB30 engine. As a self-employed engineer, fabricator, and welder, I took on the challenge of building this vehicle in my shed with support from a small team of skilled friends.
In February 2025, we successfully completed the build and ran the car on a hub dynamometer, ensuring all systems were calibrated and functions tested. This marked a crucial milestone in our journey. Now, we face the next challenge: packing the car and transporting it across the globe to compete in ‘Bonneville Speedweek’ 2025.

Soldering tips part 2: Getting the job done

21 February 2025

We touched on some simple de-soldering methods in part one of this two-part series.
Just like other workshop tools, there is more than one way to achieve it and with less damage and frustration.
De-soldering involves removing the solder from the joint to either release the component or repair the solder joint. The aim is to do this with minimal damage to either part, but since you can generally replace the component, protecting the PCB is paramount.
SMT (Surface Mount Technology) is a whole other subject, and because of the design and density of the components, different tools are required.
De-solder or rework stations consist of a box controlling a heated tip and a vacuum pump. There are many manufacturers, but I’m only going to discuss some of the ones I’ve had experience with.
While the control box may have shrunk, there is a limit to reducing the handset. The handset consists of a tube to collect the solder and filters to absorb the flux residue. The tips are hollow and reach right through into the collection tube.

A movable bench with fold-away legs

14 February 2025

Before I down-sized my workshop, I had a garage workshop area and plenty of room to have the traditional type of sawhorses or saw stools. Now I have just half of a double-garage which means the stools have to be stored out the back in all weathers.
I was looking at a sheet of 16 mm ply that was 1200 mm square and could see it would make two stools that would fold away flat and could be stored inside. They wouldn’t take up space standing permanently in the garage/workshop and they would need very little room folded away.

Waka building – Tradition goes hi-tech

4 February 2025

Architect, designer, sailor. Add lateral thinker, enthusiast and passionate Kiwi to the mix and you have the CV of a Christchurch man who has made it his mission to put Maori waka back on the water by marrying traditional knowledge with today’s technology.
Quentin Roake’s goal is to find a way to build waka in numbers, recreating the appearance and characteristics of traditional craft in a modern version that is portable, durable, and economical to manufacture.
“The big question is, how do you translate the traditional form of canoe into modern materials? You can’t cut down a big totara tree every time you want to make a canoe,” he says.
Quentin’s quest for a solution involved consultation with tohunga waka (canoe experts), including Hoturoa Barclay-Kerr and Sir Hekenukumaingaiwi (Hector) Busby, and led to Nga Waka Tangata kaupapa, a collaborative project to develop contemporary forms of waka.

Soldering on Part One

31 January 2025

Everyone knows that at some stage you need to blame your tools (after the other excuses have run out), and like most things you can pay a little money or a lot, and sometimes there is little difference in the result … or so it would seem.
The purpose of this article is not to separate you from your hard-earned cash, but to share a few tricks and provide some information to make an informed choice when buying equipment.
Everyone knows that the best soldering iron is some large lump of material that you throw into the fire until it is red hot and then apply to the job and hope that some of the exploding material fuses the bits together.
That might work for joining two bits of metal together but it is not going to work for electronics.
Soldering electronics is not only mechanical bonding, but also making an electrically conductive joint. The solder used has a particular temperature range and too hot will ‘cook’ the joint and make it porous, while too cold means it sticks to one or other part but doesn’t bond.

A six-part magazine series on the restoration of a 1952 AJS Motorbike
PART TWO – Metal plating:
The secrets of successful nickel plating
In part one of this restoration series, Peter described how he started rebuilding, as cheaply as possible, an old bitser AJS 500 motorbike, and discussed the start of his nickel-plating tasks.
For this Rust to Rrroarr project, he has decided on a nickel-plating finish instead of chromium for his AJS. In this part two of the six-part series, Peter describes his nickel-plating process

On the road again – new life for old caravans
The allure of a classic caravan can be strong, and many of these gems are being lovingly restored – in fact, Beach Hop even has a prize for the best retro caravan.
In this issue, we showcase three very different caravan restorations—one by a man who owns a company that has been building caravans commercially since the 1950s and is now a household name in caravans and Motorhomes.
The second is a lovingly restored 10-footer that started off a real basket case, and the third, well, friends christened it a turd emoji when they saw the project bought by Marty and Zoe.
Their caravan was destined for their annual pilgrimage to Beach Hop, where thousands gather to show off their super-primped or lovingly restored classic vehicles and caravans

Out of the shed and into the sun – part 1
After storing his bike for 50 years, Peter has begun t o restore it. He doesn’t want his bike to look flashy and new; he just wants it to run well and look the part.
In The Shed magazine December/ January 2025 issue 118, we begin a six-part series on the restoration of a 1952 AJS motorbike.
This series of videos will accompany each article from the magazine.

DIY audio utopia

4 December 2024

I’ve always been interested in music and hi-fi and always thought the best scenario for serious listening would be a dedicated sound-proof music room where you could listen at all hours of the night at any volume without disturbing anyone. A man cave for want of a better term.
I was lucky enough to buy a house with a large detached garage which the previous owner had built for his automotive engineering pursuits. At 13m x 5m, this is unusually large for where I live in London and would never get planning permission nowadays, of course.
The garage is a single-storey prefab of concrete construction with concrete corrugated roof panels, which was common in the 70s. For many years, the garage was just a storage facility and rubbish dump until I finally got around to transforming it into a music room and art studio for my wife (always good to have a guise for spending large amounts of time on a DIY project – I’m doing this all for you, my darling).

Small vehicle, large challenge

28 November 2024

The miniature Land Rover is called a Toylander and two lucky grandsons in Australia will soon be taking delivery of a toy that most kids only dream of. Toylander is based in the UK and sells plans and kitsets for a variety of vehicles. Graham came across their website and bought a set of Land Rover plans on impulse, thinking he could knock one up for one of his grandson’s birthdays.
Rather than being a quick job, the project got under his skin and became a bug that has seen the house renovations put on hold, the new shed delayed and a couple of birthdays slip by in the year and a half it has taken to complete.
Although the Toylander plans are comprehensive and highly detailed, Graham’s version has gone far beyond the basic instructions.

Steampunk toys

22 November 2024

A steampunk toy (for want of a better term) combines two passions of mine. I love making things that are a bit different, even a bit quirky. Something that stands out from the run of the mill stuff that you buy at the shops. Secondly, I enjoy the challenge of bringing together bits and pieces to make seemingly disparate objects into a semi-plausible whole toy. Steampunk toys give me the opportunity to do both.
