  • There are hundreds of excellent resources out there that will help you build your own CNC machine. Listed here are some that I found useful. I will include other resources as I find them and by recommendation. This isn’t a…

  • When we bought our current house it came with the mother of all rockeries. I kid you not this thing was built to survive a direct nuclear hit. The largest stone probably weighed in at 150kg and perhaps more than…

  • Now you might be wondering how someone could do a review of a hammer. It’s a pretty simple device after, all it goes up and down and things underneath it get broken (or occasionally hammered in). Well this review is about…

  • In order to complete the LED Cube project I’ve been working on I decided I needed a glue gun to hold the LED’s in place. I could probably have used epoxy or even silicon sealant as there was no real weight to…

  • The previous two articles have covered the basics of LED theory and gone into some of the maths behind designing the circuit that will power and LED. This article covers more complex arrangements of LEDs and the design of our…

  • The first part of this guide talked a little about the project and gave a bit of an introduction to LEDs. This part discusses the use of LED’s in more detail with a little simple maths which can be used…

  • Recently, despite having dozens of other interests and things to do, I’ve been finding myself getting into electronics. I don’t suppose this will become an all consuming passion but I’d like to get to the point where I can build…

  • Our daughter has a toy train (from ToysRUs) which she really enjoys playing with but the other day she threw it on the floor from her high chair and most of the noises it made suddenly stopped working (hmmm, was…

  • Next morning I decided to have a closer look at the damage and try to finish the thicknessing by hand. On the Jet JPT-260 it is possible to disengage the feed rollers which should allow for manual operation. After setting…

  • A while back I bought a second hand Jet JPT-260 planner thicknesser from Aximinster. I didn’t get much chance to use the machine for a while after I’d bought it but recently I’ve been putting it to good use squaring…

  • One of the most worrying aspects of this machine build is that it’s been essentially impossible to tell if it will work until it’s all but complete. The only major piece of functionality that I didn’t absolutely have to fit…

  • Fitting the motor posed some interesting problems since I had completely neglected to design in any way of getting to the feet to insert bolts. Fitting a carriage to the motor which could be more easily attached was clearly out…

  • With the pulley mounted to the driven shaft I moved onto the motor. The first thing to do was to fit the pulley to the shaft. The taper bush required a little encouragement to get it started on the shaft…

  • Now that the idler stock is complete I moved onto the drive shaft. I learnt a lot of lessons about make the roller from making the one for the idler stock and I managed to ignore most of them. The…

  • Ironically the rollers, which I thought would be quite simple, turned out to be fairly difficult to get right. The problem I faced was similar to the problem I faced with the tensioning system – the bar or perhaps my…
