Get on yer (electric) bike!

The thought of having an electric bike is very tempting and makes the idea of reaching that café far more appealing but the cost of replacing your bike has you thinking twice about making the jump.
Besides being a bit dusty you have a good bike that cost a few dollars in its day and it seems a shame to banish it to the corner of the shed forever. What if you could turn your bike into an electric bike without breaking the bank?

The Shed January/February 2020, Issue 88, in shops now

For many of us Kiwis, summertime can mean it’s time to dig out the family tractor. Because summer means beach-holiday time and using that good-old-boy tractor to get the fishing boat in the water as often as possible. To celebrate our love of old tractors, we head south to meet a tractor restorer from Oamaru, one Colin Harvey, who has shedfuls of tractors and spends all his time tinkering with and restoring some great classic farming workhorses.

Generators: Let the power be with you

As winter approaches and power outages become something of a given, we thought it might be useful to identify what you need to know about generators, safety, their uses, and how to connect them to your home.
A generator is a motor driving an alternator to produce power, and with the advent of these Inverter Generators (see my review of Honda inverter generators) the basics haven’t changed, but how they operate has.

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.
