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.
Australia’s Lucas Mill celebrated its 25th year in the business of making portable sawmills. More than 18,500 Lucas Mill portable sawmills have been sold into more than 100 different countries, and the company says its first portable swing blade sawmill is still operating.
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 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.
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.
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.
Honda’s inverter generators are famous for their reliability, fuel efficiency and portability but they also supply ‘clean’ power for phones, laptops and power tools. Older generators can produce power spikes or variable voltages that can damage modern appliances. The portable EU10i was the first generator of its size to feature a sine wave inverter assuring commercial-quality electricity.
Always wanted your own knife-makers forge? Well in the July/August Issue 85 of The Shed we show you how to make two differing styles, one using LPG power and one using used engine oil to create the heat. What a great way to dispose of old oil and both give great results without incurring huge build costs.
Then we…
Watch this video and be impressed at what these core bits can do
The drills have a vacuum-braised diamond cutting edges for longer life and strength. The range of Tusk VB core bits are for drilling, grinding and cutting using angle grinders for precision and control.
The answer came like a light bulb. In fact, it was a light bulb – one that fits snugly under the top of the drill press and shines on the complete work area below, with little or no chance of casting unwanted shadows. It’s easy to make, as you can see from the step-by-step pictures.
Good news, the Auckland Blade show is back on again this spring. Same location, 545 Parnell Road, Parnell, Auckland and this year it’s on the weekend on 12 & 13 October. See their poster for more info.
The Shed will see you there.
First we checked to make sure that the there was in fact some play in the quill and indeed the dial gauge showed run-out of over 0.5 mm, quite a significant amount of wobble. I felt vindicated and quietly pleased that I hadn’t dragged Russell away from oiling and balancing the wheels of industry on false pretences.
Back when I was sharpening drills as part of my punishment, I discovered there were slow spiral and straight-fluted drills for brass and plastic. You may need a straight-fluted drill. You can create this by “backing off” the first 3 or 4 mm of a spiral-fluted drill.
Got some tiling to do? Need some best practice tips?
Well here are three videos from Selleys with advice on fixing tiles to a surface, grouting and finally sealing the tiles.
Its all done using Selleys products so you can be sure of a great result.
Enjoy.
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.
