    Default 1/5th Scale Peny-Darren 1804 Locomotive

    Hi All,

    For my new project I will be building a replica of Richard Trevithick's 1804 Steam locomotive. It was run at Peny-Darren - thus the name, on 14th February 1804. It ran on cast flange rails (no flanged wheels). It was the first train to tow a load - 5 trams of coal and 70 men. However the trip didn't last long a the smoke stack hit a low bridge nd was seriously damaged. I am building this because I am a bit of a train fanatic. I have found a fair bit of detail, unlike my original plan to build Stephenson's rocket - not much detail available. This locomotive does look a bit weird and I think will provide a great challenge. I am building it 1/5th scale and will provide quite a number of posts of my Work in Progress. Some photos of the loco are shown below.

    Regards

    Keith

    Hi Keith, I will be watching with great interest. The 1/5 scale , how big are the wheels, and diameter of the fly wheel. John.

    Hi Guys,

    The drive wheel gears on my model being 1/5 scale are 150mm diameter. The main drive gear (centre gear) is 250mm diameter. The locomotive wheels are 225mm diameter. The flywheel is 480mm diameter. The boiler is 250mm diameter X 320mm long. The drive cylinder is 35mm diameter X 175mm long. The smoke stack is 45mm diameter X 425mm tall. I have made up some scale plans of the gears and flywheel and will be gluing these onto the timber - using pine - and will then cut out each individual gear tooth using coping saw (a lenghy task). I need to put the pine through the thicknesser to bring it down to 12.5mm which is the scale width of the gears. I am really looking forward to this project as it something out of the ordinary. Photo of my plans are below.

    Regards

    Keith

    Keith, do those gears have an epicyclic profil or some other sort of profile?

    The profile doesn't look like involute gear teeth. It looks cast (rough) and probably not machined ?? would be very noisy in my opinion.

    I don't know whether you can see clearly in my plan. I will research further for you if you like.

    Regards

    Keith

    Richard Trevithick also built "Puffing Devil" which broke down so they all went to the pub and the boiler ran dry destroying it. This was very similar to the train you are going to build.

    Looking forward to this build

    Artme,

    Have tried to get more info and research on differing gear tooth profile used in early 1800's but no real success.

    Regards

    Hey Keith I was just having a snoop around and found a ripper of a book.
    Life of Richard Trevithick with an account of his inventions, published in 1872.

    It's over eight hundred pages and can downloaded for free on Google Books.
    Thought it may be of some help.

    Trevor.
