    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 and analyze a simple circuit. Ever since I was at school (which was a long…

    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 that really a bad thing?). Being the sort of person that can’t bare to see…

    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 everything up I disengaged the rollers and tried to feed a piece of wood in.…

    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 up some oak stock for a log store cabinet for the living room. Unfortunately four boards…

    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 before having a trial run was the tracking system. I have, however, finally got to…

    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 as I had only a few millimetres of clearance above the motor so it was…

    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 in the form of a few light taps with a wooden mallet. Once on it…

    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 driven roller isn’t quite as crowned as the idler roller partly by design and partly…

    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 drill bit didn’t seem to be quite the right size. Unlike with the tensioning system…

    Of all the parts of this project the one that probably caused me the most trouble was the tensioning and tracking system. It’s not strictly necessary for the two features to be built as one piece, you could tension the drive wheel and track the idle wheel but I felt it made sense for them…

    The idler carriage was the first part of the belt sander that I actually put together because it involved solving almost all of the main problems with the machine in one compact piece. The main problem I felt I was going to face was mounting the bearings and getting them aligned fairly perpendicular to the…

    Now that the parts are all cut out it’s time to get started on building the case. I actually started making the idler carriage first but I’m presenting the case construction first as that seems more logical.

    I’ve now cut all the pieces for my home made belt sander out of MR-MDF. I hate working with MDF, It seems no matter how much extraction I’ve got going the dust still seems to go everywhere. A problem not helped by the fact I did a lot of the cutting with a jigsaw and…

    At last I think I have a design that can build and that is also built out of components that exist in this universe! By spinning the motor round and having the disc sander powered off the idler shaft I think I’ve incorporated all the features I wanted.

    Right so I’m now onto design number three and the wheels have come off a bit. Thinking I had the design pretty much sorted I rushed out and spent a load of money on parts. What I should really have done though is had a good think about how I was going to fit the…
