Positive trends for gender balance in the electronics and engineering industries

30 November 2022

A new survey on global trends affecting women in the engineering/electronics industry has revealed that, although they still face major challenges, there are positive trends that highlight a continued movement towards equal treatment, regardless of gender.
This is the second survey element14 has conducted that is aimed at shedding light on women’s experiences, career paths, wider challenges, and opportunities in the engineering/electronics industry.
The results show that inequality needs to be addressed to achieve the equal treatment of all, and that women around the world remain underrepresented in the industry and continue to experience various forms of sexism and discrimination.
New questions covering discrimination, sexism, and equality were added to the 2022 survey, as these critical issues were noted as key areas in the original 2021 survey analysis.

A Primer In Hydraulics

23 November 2022

Now that you have a basic overview of some of the components that go into making up a hydraulic system, let’s take a look at a practical application. The wood splitter is a good example.
First you need to determine what you are trying to achieve. In the case of our log splitter :
* How much force is required to split the timber?
* How fast do you want to complete a full cycle i.e. ram full out and full return?
* How much horsepower is available to power the pump?
We will illustrate an example using a single-stage pump with a safety margin of 200 bar (pressure
in bar: 1 metric bar = 14.5 lb/in²).
It must be emphasised that an oil pump does not pump pressure, but flow. Pressure is created by the load on the actuator

In the November/December issue 105 of The Shed, our cover story is on a Kiwi legend of metal shaping and motorbikes, Steve Roberts.
If you enjoyed that article here is a link to a website that has even more of Steve’s story as well as videos of the cars and bikes he has constructed and inside info from chats with Steve.

How to repair a thread

2 November 2022

Damaged and pulled threads can be an annoying inconvenience, especially a stripped spark plug thread. They can also be expensive if the equipment you are working on is vital or difficult to replace. But there are now systems with which you can repair even completely destroyed threads quickly and at a reasonable cost, so saving time and money.
Existing undamaged threads can also be significantly strengthened using these types of repair systems.

Which air compressor?

21 October 2022

Selecting the correct air compressor for a particular job should be a relatively painless exercise. The right choice will provide you with a useful machine that can last for many years, provided you maintain it well.
But far too often, choosing a compressor can come down to a random weighing-up of price, cosmetic appearance, or misinformation about the compressor’s specification. In fact, the most important thing to consider is the air consumption of any tool to be used with the compressor.
The saying, “You wouldn’t buy a Mini to tow a boat,” holds true. If the compressor is too small for the job, either the tool won’t work or the tool will work below an acceptable level

18 October 2022

One of our favourite sheddies here at the magazine is Rudi Buchanan Strewe whose engineering shed we featured in issue 102. When we visited Rudi, he was restoring a 1910 Atlas power hammer. Here it is, restored, and up and running as good as new.

Milling Part 3, cutting, clogging, and cleaning

5 October 2022

Once your component is securely clamped (see “Showing restraint” Part 2, www.the-shed.nz), ensure the cutting tool is held correctly in its chuck or collet holder, keeping tool overhang or stick-out to a minimum. Being rigid and stable applies as much to tooling as it does to the workpiece. Drill chucks are NOT designed to take side loads induced by milling and are exclusively for drills. Milling cutters should be held in a collet chuck or other suitable holder.

Legendary panel maker
The unassuming Steve Roberts has been called everything from artist and magician to guru of alloy; he himself is more comfortable with the handle ‘tin basher’
Our cover story this issue is on a legend of metal shaping and motorbikes, Steve Roberts. Steve is one of this country’s most respected and admired craftsmen in these fields, and we made the journey to Whanganui to catch up with him.
His output has been prodigious; his innovations groundbreaking; his production values and eye for detail next level. Incredibly, most of his work has been conjured, beaten, and bent with ‘basic tools’ — an indispensable 1920s lathe, a homebuilt press, and an ancient wheeling machine — from a modest shed he once shared with his family’s horses

Milling – showing restraint

27 September 2022

In Part One of this series on the milling machine we put the milling machine in the workshop and had it levelled. Before you use the machine, it is important to check the alignment of the spindle. Then comes understanding the importance of preparing the workpiece. Work to be milled or drilled on the milling machine has to be set up so that it does not move during the job. This is one of the most important things you can do if you don’t want an important component or workpiece to end up as scrap because it moved.

Time for a milling machine?

21 September 2022

In a typical home engineering workshop progression, you buy a bench vise, some hand tools, and possibly a bench grinder. After you buy a small pillar drill then comes a big leap — buying a centre lathe.
Along the way you acquire more small tooling, drills, turning tools, etc. You make many useful items and produce a fair bit of scrap.
But then you find the lovely pieces you are turning out on your lathe require other features, especially holes more accurately positioned than you can mark out and drill on your pillar drill. As good as you have become with a file, that flat section needed on the shaft really needs to be machined. And how are you going to make a slot for that keyway?

Create a coffee table

1 September 2022

Making an item of furniture does not have to be the daunting task it can seem. If you look closely at commercial pieces, you’ll notice that they share common concepts, and they are simple concepts at that. I’m not suggesting you suddenly choose to give away purchasing furniture and make all your own but making one or two items can become real statement pieces. Perhaps a hall table, or in this case, a small coffee table.
For this project, instead of choosing a basic option of joining a few narrow boards side-by-side to create a solid top, I chose to try a technique I haven’t used before – using wedges of timber to create a radial effect. For your top, you certainly do not have to go this far, and you can choose to have a solid top (these can even be purchased pre-made), or even a solid slab (with or without a natural edge)

Build a portable barbeque

24 August 2022

At home, I have a big barbecue in the backyard and a little barbecue upstairs on the balcony that I use when there are just two of us. This hibachi or portable barbecue would be ideal for just two although the grill rack is big enough for four or five steaks or chops and sausages. It can be made with scrap mild steel and a piece of cut pipe. You will find scrap bins at your local engineering works. Most pieces of metal under a metre seem to go in there. You could ask and many companies would be happy to help out, perhaps for a couple of beers.

IoT key driver to growth and leadership opportunities in key industries

22 August 2022

A new global survey on the development of the Internet of Things (IoT) across a wide range of industries has revealed some interesting new trends, including a surge in willingness to use AI in some form, increasing concern about connectivity options, and a willingness to establish partnerships to accelerate the delivery of new IoT solutions.
The Global IoT Survey 2022 was conducted by element14,an Avnet company that specialises in the global distribution of electronic components, products, and solutions — and analysed 2263 qualified responses received between January and March 2022 with the aim of gaining a better understanding of technologies, challenges, and opportunities faced by designers and system integrators of IoT solutions.
