  • Just for fun ... a Porter in OOn2

    Hi,

    A while back I started modelling in 009 ... 1:76 scale models running on 9 mm track. It's mainly a British thing, which also means that most available models are based on British prototypes. I however recently noticed that Minitrains started selling there steam (an also diesel) chassis separately.

    http://www.minitrains.eu/e/minitrains-special.html

    It occurred to me, that I could of course model a 009 locomotive based on a small US prototype with this chassis. This would also mean that I should not be calling it 009 any more, but according to the US convention should stick to OOn2 ...

    So I started out by creating a 3D model of a small 0-4-0 Porter, which I based on a drawing of the Grandt Line model.



    Do be able to do a test fitting on the chassis I order a print from Shapeways a couple of weeks ago and I picked it up on Saturday. From what I could see with the first fitting, the dimensions of the (not fully completed) model are correct.





    Although it is just a test print to check if it fits correctly, it also gives me the opportunity to try to get the printed surface as smooth as possible. I first worked it with a fibre pencil and then gave it a couple of thin layers of grey Tamiya primer. The pictures do not show it that well, but there is still some work to do ...





    Cheers,

    Jeroen

    Nice looking start. The 3D printing seems to have given a very smooth result.

      Jeroen,

      The surface looks realy nice in the photos. Can you tell me how well the mechanism runs?

        Fantastic! I really like how it is turning out.

            It looks like you're on to something, Jeroen. Your test print looks pretty good.

              Nice design. Where did the stack come from?

                Rod,

                The mechanism runs very well, even a slow speeds. The same mechanism can be found in the new Koppel and Kraus by Minitrains.

                Jeff,

                It is the original stack which was supplied with the chassis. I know it is a bit too long, but I am planning to desin a new stack myself, similar to the one on the Grandt Line Porter.

                I am however still looking for a decent bell and whistle. Anybody any ideas?

                Note that it is 1:76 scale, so it should be a bit larger than the ones you would be using for a HOn30 or HOn3 model.

                Cheers,

                Jeroen

                  Your little loco looks great, and the printed casting looks smoother than most. As for the bell and whistle, why not do them using Shapeways as well, then you could use them as a pattern for lost wax casting. Come to think of it, you might be able to do the same thing with the shell as well, which would give some added weight.

                  At 1:76 scale however, I believe you are really closer to having OOn27 than OOn2. a scale of 1:67.75 would be closer to two foot gauge, but then of course it wouldn't be "OO".

                    Redesigned the parts a bit. It now consists of 3 parts. I have separated the tank and hollowed it out, allowing it to be filled with liquid led.

                    This is the result up to now:

                        What is that sticking out of the stack?

                          The stack looks like it's made from a bit of brass tube and a panhead machine screw, presumably a placeholder.

                            Correct, the screw keeps the front part of the chassis together, similar to the original stack. I am currently designing the spark arrestor, which will be placed on top of the brass tube with the head of the screw inside.

                              Will you make these pieces available for purchase on Shapeways?

                              Thanks,
