    Default Istanbul's Rahmi Koc Museum of Industry

    I posted a number of photos last night of triple expansion marine steam engines on display at this museum and then realised I'd managed to slip an extra i into industry in the title. In "edit" the thread title cannot be altered so here's a revised version of that thread.

    I have an idea a few of you are interested in models and there were models aplenty on display so I took some photos. Here is a small selection. A number were made prior to 1900, some as manufacturer's promotional items. ( I photographed the accompanying identification plaque for each model should there be any interest )

    Default More than just models.

    The museum is large. It also contains engines, boats, cars, planes, tractors, trains and motorcycles. I spent six hours there. In my humble opinion worth a visit should you be in that neck of the woods.

    PS. The Turks like it too. Check out the final photo.

    Many many thanks for the pics Bob.
    I doubt that anyone who has walked 'past' a lathe let alone used one would find pics like this boring.
    That is quite a model of a beam engine, even the nuts look to scale, something that doesn't happen much anymore.
    Thanks again for taking the time to take transfer and upload all of them.

    Default Great pictures

    Hi Bob, the quality and content of your pictures never cease to amaze me.

    How do you get such clarity from a Brownie Box camera, I can't match it with my Nikkon D50 digital camera?

    In all seriousness, what do you use for a camera, lenses and settings?

    Brilliant, just brilliant.

    ps, what are you doing os anyway, holiday? Sure looks like you are having an interesting time.

    Thanks for the kind words Ken,

    It was a holiday and an absolutely fantastic one at that. Budapest, Zagreb, Split, Dubrovnik, Podgorica ( Montenegro's capital, formerly Titograd ) and Istanbul.

    This trip I had with me my old faithful Coolpix and a little Nikon J1. I had fitted an adapter to the J1's lens to enable the mounting of standard Nikon 52mm lens caps and filters because I didn't have a much smaller J1 filter. The 52mm filter is wider than the lens and proved to be a handy convenience. Most of the smaller exhibits at the museum are inside glass cases. Holding the lens by the filter adapter flat up against the glass removed reflections. If you look at the Turkish Metalwork thread you will notice there are no reflections in the snapshots. The problem in the Koc museum was that many the objects were further away from the glass requiring the camera to be angled. Reflections appear but I was able to reduce camera movement by using the glass as a support. A lot of the photos had exposure times of between 1/2 and one second. A lot of the photos were blurred and I took a lot of photos, nearly 1100. I have done a lot of culling. Dim illumination seems to be favoured in a lot of museums. I had my tripod but was unable to use it at the military museum and I foolishly left it in the hotel room when I visited the Rahmi Koc museum. Even more foolish was my decision to leave my tiny table top tripod in Perth. Next time..........

    Bob.

    Hi Phil,
    Are nuts generally to small A/F, or too thin (or both), or lacking those rounded corners at the top?

    Most of the models I've seen that don't look to scale have nuts that are too big. The temptation is to use nuts that are off the shelf and they don't scale well. The A/F dimension of a nut is typically 1.67 of the thread (at least in metric land) but for an M2 thread this is only 3.34, so a bit gets added on. While not much it does look out of place. In the big model competitions in the UK points are taken off for using off the shelf gear - which they pick because it doesn't look quite right.

    Hi Bill
    Michael has answered beautifully
    Purists will make each nut individually which undoubtedly would require a lot of patience (more than I have ever had).
    Where I did my apprenticeship, the boss' father in law was a toolmaker who was making a steam loco and as I happened to be running the boilers one Saturday he thought he would bring it in for a live steam test.
    This guy was one of those purists. Every nut and bolt was individually made. The loco had a lubrication pump that ran off an eccentric from one of the axles and when scaled down, the piston was 1/4" diameter. He also managed to machine piston ring grooves and the piston rings to match. The damn thing actually pumped like a trooper. Even with the young eyes I had in those days I was struggling to see the bevel he cut in the rings to assist in placing them into the grooves.
    It was an amazing piece of work.

    Default Well, Just Two More....

    Given the interest in appropriate sized fixings, I thought these two engines might be of interest.
