    Another Elmer #33 (Second project)

    My first project served its purpose, and now I think it's time to make something I can be proud of! I'd picked this engine before I realised that Stan was making his. When I did see, I thought again, but then I reasoned that having someone as good as Stan making his at the same time could be...

    Simple Oscillator Finished

    Hiya chaps I'm calling the simple oscillator finished. It's ugly and wobbly, but it works and has served its purpose as a learning tool. I'm going to use this experience to enhance a build of Elmer's #33. Thanks for all your help! https://www.youtube.com/watch?v=jN1Gp0-_7NM

    Countersinking

    Hi chaps, I think I have posted this in the right place, if I have not could someone move it? On the plan I am about to build I need to drill a 3mm diameter hole and countersink it. There's no specification as to the size of the countersink. I'm assuming that most metric sizes use a...

    Hi Everyone!

    Hello Chaps, I just thought I'd introduce myself, I think I'm going to be asking a lot of questions in the near future. My name is Jim and after studying to be a motorsport engineer a few years ago I ended up working in the health service, and now my new job as a quality engineer for a...
