    Filming was planned today but it's raining

    Let's start with the recovery crane.

    The flatbed is only fixed with four screws on the base frame. Electric connection goes over a sub-d connector.
    the 12v connection wasn't use on the flatbed but maybe on the crane.

    First thing today was to cut off a bit of the base frame. so the crane can end closer to the rear axle.





    considering the open utitlity box I've changed the support winches. the older are to weak and to quick.
    new flanges made and the new, normally hidden, winch arrangement



    all winches in action you can see in this little instagram clip

    parallel I've made a key feature of the train: the big double hook beam with his jigs.
    massiv brass beam with adjustable steel jigs. the little joints are two 6x10 brass pipes. hardsoldered.
    i'm very pleased that just the first attempts has correct 90 angles




    Stay tuned for more happy metal

    Thank you

    Today cranes baseframe was built. Not very impressive and most if his time hidden but useful and very stable. Overall length in this configuration is 72 cm.

    I know my and my pals driving arts, so all my backplates are really massive :)

    Hi,

    the backplate is ready machined.

    Some drilling for lights, slotting for additional anchor points, a bit shaping and, for me, a well done surface making it ready for powder coating

    Hi,

    the Build of the second payload begins. A mechanical recovery crane.
    Cranes have many pulleys. So I have to make some of these silly things. After a bit gugeling etc I know, I need a formtool. So I go to my storage and found some 10mm silversteel

    After milling the rough shape...



    ... I gave him the needed clearence angles with jewellers files.
    A first try with the unhardened and unsharpened formtool



    Looks principally good. Ergo: it's the right way to do this.




    Stay tuned for more happy metal

    Hi,

    two, later quite unremarkable, pieces are done. Unremarkable but important and not easy to done.

    The in two axis rotable pulleys for the main hook rope.

    After roundabout 15 Hours of planning and machining they're done

    The main traverse is ready to use.

    You can look at my 3d plannings with fusion 360

    you can go round, move, look, special feature is the ability to made an explosion views of the parts. You cant save your modifications. So its save. Try it.




    Last parts of the traverse are the beamflanges on the bottom.



    It was a good exercise on the roundtable
