A toddler’s table and chairs

You can follow the basic design in this article or design your own version. Once you have absorbed some of the basics of furniture-making, there is a great sense of satisfaction in designing and making your own. As an amateur hobbyist, I find the process is just as important as the finished product itself, so to check this I decided I would try to make a scaled-down version of an adult chair with a curved back.

Make a camper trailer

American teardrops first became common in the 1930s after DIY magazines such as Popular Mechanics published plans to build your own. The ultra-lightweight concept normally only sleeps a maximum of two adults in the cabin and has a small outside galley or kitchen at the back of the trailer. Often these campers weighed little more than 450kg and were very streamlined so were ideal for towing behind small cars or for long road trips.

Making a ring roller

The solution was to use the offcuts and a cheap bottle jack to make a set of rollers that can bend the material into wide arcs. Since I had to buy the $39 jack, the budget was well and truly blown. But this ring roller will be useful for future projects.

Simple hydroponics nutrient solution

Hydroponics is all about growing without soil. In many ways, this simplifies the lot of the gardener, but it gives them added responsibility for providing plants with the right level of nutrients.
As water with nutrients tastes, feels, and looks much the same as plain water, a testing instrument called an “EC meter” or “CF meter” is used.

Building a 50cc mini-kart

The design is not intended to be a high-performance, go-anywhere vehicle. It is a school project and therefore there are a few compromises in the design. It is economical to construct, achievable and straightforward for average Year 12 students. I might add, with some guidance.
It is also intended that most, if not all, of the Tools4work Level 2 mechanical engineering standards can be assessed against this project. Some of the techniques described may seem unnecessary, such as using a surface plate and scribing block for marking out, the design of the bearing retainers, or the generous use of a Bramley tube bender.

The Shed July/August 2020 Issue 91, on sale now

The July/August 2020 issue of The Shed, No. 91, has got something in it for every sheddie.
Even though there is something of a nautical theme to this issue, our cover story is on building a very powerful, vertical, hydraulic log splitter. Bill Stevenson from Christchurch walks us through the construction of his trailer-mounted log-splitting machine that was started prior to the Covid-19 lockdown, worked on during, and completed immediately after. A great effort.

Building a Stirling engine

I always get a thrill at seeing one of my engines running for the first time. It was especially true for this one because I had had no previous experience in making such an engine. The engine runs at about 600 RPM with a good differential between the hot and cold ends of the displacer tube.

Work, life and play

Most people have separate places for work, play, accommodation and their hobbies but Malcolm Anderson has successfully managed to combine them all into one.
Malcolm’s father, Bruce Anderson, has a passion for collecting and restoring motorbikes to the highest standard. One of his projects, a 1929 Harley-Davidson OHV Two-port Special that he restored from a pile of parts, now resides in the Harley-Davidson Museum in Milwaukee in America.

Make useful trammels

A trammel is a really useful item to have when you need to mark a curve onto sheet metal, plywood, MDF, plasterboard, or even a paved surface when painting lines for a netball court.
Sure, you can use a pencil and a piece of string but there can be a variation due to the angle that the pencil is held and differing tensions on the string. A trammel will easily produce an accurate arc.

Rimu Dining Chair

Start by drawing a full-size plan of side elevation and seat plan. You will probably want to make at least four chairs so it is easier to measure angles and sizes and maintain consistency in measuring from a full-size plan. Make a template from 12 or 16 mm MDF or plywood for forming chair back legs directly from the plan shape. I have found the easiest and most accurate method is to punch holes with an awl or sharp point and simply connect up the dots.

Installing an automatic gate

With the benefit that he worked for an engineering workshop, Karl knew that making the gate wasn’t likely to be a problem. He didn’t want an elaborate gate, rather one in keeping with his house that would tone in with his existing wooden fence.
