    Here you go Ken. It converted to the GN version very early on.

    It’s probably done about 130 miles by now.

    In awe of your talent and ability. What a fantastic model this is and truly a worthy loco for CF.

    I make lamp irons the way you do but mine in 7mm look clumsy by comparison!

    Found some castings for the tender axle boxes at the show which with a bit of work, at work, will save me quite a bit of time.

    Tim,

    When it went past the tweezers, that were near-on the same size... well, just fantastic.

    I must try harder. I must try harder...

    Best

    Lot's of different coloured materials here. I seem to remember you using various heavy metals to get weight into the loco.

    There aren’t any exotic heavy metals in this engine, Ken. It’s big enough to be heavy without trying. The boiler / firebox is made from solid gunmetal, brass and nickel silver, with the motor-gearbox occupying very little space, as it is low down between the frames, as can be seen in these early photos.

    The cab is cast in ‘student’s alloy’ - brass - from plastic patterns, whilst the front end is white metal from an A4 casting (only the good will left of that though).

    The whistle will be turned from gold, so that will add a bit of weight! I’ll put her on the scales at work and report back. LP is capable of pulling anything we want to put on the back.

    Hi Tim,

    Many thanks for sharing photos of your work. I have been admiring your models since the article in Model Railways (??) about the MR Spinner.

    In my humble opinion, you set an impressive benchmark, not only for 1:152.4 scale but for larger scales as well.

    The motor set up in Lord President is also impressive. Can you supply details of the motor and the attached gear-head please?

    Many thanks and best regards,

    Peter

    Thank you for the comments Peter. You realise that Spinner was made 40 years ago?

    The motor-gear head is an 8x16 motor and a 1:4 gearbox made by Maxon. They are rather expensive with the Swiss franc and pound at their relative values, but as I usually take so long to make a model, the investment is spread over glacial periods of time. It is coupled to a modified low ratio transfer gearbox that I got from C&L, giving an 80:1 overall reduction. The brass flywheel might also be useful, although there wasn’t much room for it: tungsten might have been a better choice.

    The slow running Maxon motors (often with gear heads) have become standard on Copenhagen Fields, where we need massive reliability.
