    This is my first attempt at scratch building a loco in 7mm from a drawing out of the Railway Modeller magazine from 1975, it is drawn as first designed late 1800s however my build will use photos as inspiration to build one as being used in industry late `50s early `60s.
    First the drawing.
    [​IMG]
    The frames (chassis) cut from brass flat.[​IMG]
    the cylinders from brass tube with the ends blanked.[​IMG]
    Cylinders fitted to the frames on threaded rod, wheels and axles in place the front axle has rocking suspension which gives better pick up.
    [​IMG]
    the motor gears and some of the white metal castings I collected for the project.
    [​IMG]

    I have made my own cross heads and piston rods as well as connecting and coupling rods.
    [​IMG]

    The slide bars supports I cut out of brass sheet with my piercing saw and soldered some narrow strip to them to give the appearance of being cast.
    [​IMG]

    The brake hanger bars.
    [​IMG]
    The brake shoes them selves I cast using a plasticard pattern from which I made a mould using domestic mastic and cast them using 5 minute epoxy resin.
    [​IMG]
    I glued the brake shoes to their hangers with super glue and soldered them to the frames.
    [​IMG]
    I built up the cab sides.
    [​IMG]

    Made up the boiler backhead.
    [​IMG]

    Made up and fitted the cab rear-though I am going to have to remove it and re-jig it as I am not happy with the fit, it stands about 1-2mm high.
    [​IMG]
    The buffers, chimney and valves are only loosely fitted for effect.

    I haven,t posted lately on my Barclay mostly because I haven,t done any work on it but the last couple of nights I have started working on the brake linkages, I,ve been putting it off as I wasn,t sure how to go, anyway I took a bite on the bullet and got stuck in, the prototype has a shaft that runs across the rear of the frames ( chassis ) that has a screw operated hand brake from the rear of the cab,
    [​IMG]
    sorry I should have rotated the photo before uploading but it gives an idea of what I am on about.
    I have started by making the brackets that connect that rod to the brake hangers via bars and also the bracket that connects the air/vacuum brake cylinder.
    [​IMG]
    [​IMG]
    [​IMG][​IMG]
    anyway that is the state of play at the moment, some thing very small that took me the best part of 5 hours to make :twitch:.

    Now I have got this far the hardest part is done, still a lot to do though!

    Cheers, Pete.

    Of course, they'll be working brakes :facepalm:, just need to work out how often to re-shoe them.

    Congrats on Pic of the Week. You definately deserve the top spot as this model, although 50% complete, is a stunning piece of work. Keep the thread coming. :thumbup:

    Cheers, Gary.

    Thanks chaps, it is a long winded build I must admit, trouble is I am easily distracted ooh a shiny thing I need a shiny thing, oh where was I oh yes easily distracted, I have got about a dozen projects on the go at once with modelling and my resto project and truth be told I sometimes can,t make up my mind what to do so- I do nothing, this week I was re ringing my Lister B engine, I need to lift the hopper/cylinder back onto the crankcase but its too heavy to lift, so I have started building my own engine hoist, I don,t have all the parts for that yet so thats come to a standstill, next I was reading about model coal offices and that reminded me of the one I have built but with a different method so I started playing around with that! which led me on to the station building to go with it, while waiting for the glue to dry on that I started doing some more work on the iron foundry smelter for Wheeldon Mill, so I will get there eventually it will just be in fits and starts, I hope not too long from now.

    Sorry for rambling all over the place :lol:.
    Cheers for now, Pete.

    Spent two and a half hours on the brake gear this afternoon, I started by making the bracket for the right hand side brake shaft and the hand brake counter weight,
    [​IMG]

    next I made the bracketry for the hand brake capstan, I found the capstan casting a little too short, so I extended it with a short length of brass tubing,
    [​IMG]

    I,ve knocked off for now, next I need to make the bracket to connect the capstan to the brake cross shaft, then I can solder every thing up.

    Cheers, Pete.

    I dragged myself back into the shed again to do some work on the A/B, didn,t go quite to plan but it will do for me.

    First I made the bracket for the hand brake to connect to the brake capstan, some where in the soldering it twisted but as it took me 2 hrs to get this far I left it.

    [​IMG]

    Next job was to fit the rod, counter weight and bracket.

    [​IMG]

    Lining up the screw and buffer beam bracket was fun :twitch:.

    [​IMG]

    As can be seen it is a bit twisty, hopefully it won,t show up too badly when painted, fingers crossed.

    [​IMG]

    Capstan in situ, not fixed yet.

    [​IMG]

    Thats it for now, cheers, Pete.
