    Sounds good Toto enjoy the build. I did an M&M 20 ton brakevan once... they are nice kits but you may have to drill the axleboxes to take the bearing cups. :thumbs:

    Wheels and Bauxite paint arrived.

    Question, what is the wheel base for these wagons ?

    Thanks Paul

    And here is the result of the answer

    upload_2020-4-5_12-1-26.png

    This one does 8ft to 12ft 6inches in 6inch steps

    Hopefully will get a test print started this afternoon - approx 4.5 hours to print.

    There is a larger version 8ft to 16'6" but because its bigger than the build plate, has to angled and will take approx 15 hrs to print.

    Well, camera is on charge and busy conditioningnmy brain into the idea that I'm heading for the shed shortly.

    As the photos will show, the shed needs a bit of a clean up 8n order to make space but nothing major. I'll set up my laptop for the Skype conferences with Dundee and Yorkie as he has expressed an interest in joining in just for the crack ..... and possibly on an advisory roll.

    I'm looking forward to this. The initial foldmup box section for the wagon body should be straight forward and when done, gives the I impression of good progress. All these things help in building confidence and enthusiasm for someone of my " beginners " ability.

    I need to look out some wheels as before you know it, they come in to play as there are not a huge amount of parts involved in this build. ..... possibly a good thing.

    I will also try and locate the various sizes of iron tips that I have as I would like to use something of a modest size rather than jumping in there with a tip the size of a Jack hammer. Keep the soldering as minimum as possible to reduce the amount of clean up afterwards. Obviously it still has to be big enough to deliver the heat from the iron sufficiently to the parts in order to get in and get out. A good solder and flux will help there also.

    The PITA element of this build is the chassis lattice as it will be a challenge keeping this square and flat. There may be a little time spent on some basic form of jig to assist with this. We'll see what ideas the collective minds come up with on that subject. Hopefully something effect tive as I have a few of these M and M wagons of varying types but all of which are supplied on the same construction principle.

    I should be back on within the next couple of hours at least showing the progress with organising the work bench and showing the selection of tools used and more on the victim.

    Cheers for now

    Toto

    As above, I've been busy in the shed looking out all my weapons of mass destruction. :avatar:

    here is where we are ........


    teraaaaaaaa ....... a reasonably clear work space has been created ..... and


    found the solder .....


    Various types of clamps .... although thats not them all .....


    Variable temperature soldering iron ( as well as a collection of fixed temperature versions at hand )


    An 8 inch hold and fold ......


    various files .... and tools.

    there are more tools and other materials in the armoury but I wont bore you all with that.

    I have various other jigs and clamps and fluxes and all sorts.

    Now ....... just to get down to the build ..... simples ...... :avatar:


    stay posted for the first of the updates. I have just tested my skype on my " shed laptop " and after renewing my Skype details and testing that it works ( with Dundee ) I think I am all ready to go. I just need to check that I have some laughing juice in stock ....... for medicinal purposes.

    catch up soon.

    Toto

    Now,

    just to remember everybody of the victim ......


    complete with Poppys internal wagon sides ....


    The various white metal castings .....


    and of course the etched brass components .....


    study their beauty keenly as they may never look this good again.

    Still have to look out the wheels which I'll do now as they do come into play quite early in the build.

    Cheers

    Hi Toto. My advice (for what it's worth) is leave the 70 degree solder in the packet, stick to the DCC Concepts 100 degree, and cut it up with tinsnips or similar into short but useable 'sticks' as you'll find it easier to use.
    Keith.

    No worries, I take it thats for the white metal element.

    i found both wheels and potential buffers ( advice needed on the buffers ) ....... That was painless. Found them quite easily for a change.

    here is the wheels


    wheel type as recommended in the destructions. and here are some buffers that I have ......


    I am sure that I have other variants available too if I need them.

    cheers

    started the build .....


    main body removed from the main fret and the little half etched tab flash filed off to match the contour of the body.


    first snag above. I dont know if you can see this very well but the brass wont go deep enough into the folder to reach the half etch bending line.

    We wont be beaten on a small glitch like that though .......


    not when you have these bad boys .......


    problem solved and the first side is bent up at 90 degrees to the floor.


    and the second side gets the treatment as well.


    all sides and the ends are now bent up to shape ready for the next step.

    first, solder all the corners in to place and then fit the side mid stantions ( white metal ) into the pre made slots. Apparently there may be a little fettling required to get them to fit just right. We shall see.

    more soon.

    cheers

    If you can Toto, tin the brass where the white metal will attach first with 'normal' solder, then you'll find the white metal will solder more easily to the brass using the low melt solder, and yes, I was referring to white metal soldering with the 100 degree stuff in my previous post.

    Thanks Keith.

    I will tin the brass as suggested. I've heard of that before. Apparently it creates an Alloy out of the different solder types ....... all beyond me. :avatar:

    Ok,

    this is as far as I'll be getting for tonight.

    as keith mentioned, I have tinned the brass where the stanchions will be placed. note they will be place from and soldered to from the inside .....


    So the tinning is done but before the stanchions are soldered in place, the four corners need to be squared up and soldered up.


    one of the four that have all been done.

    I will pick up on this tomorrow as I will be doing a little experimenting on scrap brass and white metal before wielding my iron at the victim.

    catch you guys up tomorrow.

    cheers

    Thanks Yorkie.

    Tomorrow is white metal challenge day :avatar: I've done the tinning with the " normal " solder so I'll be interested to see how the 100 degree stuff takes to it.

    One of the stanchions have already broken but can be soldered ok I think. They are an awkward fit. The second went in no problem. I wondered whether a scratch built version made of laminated brass etch might have been a stronger option for later handling purposes. May look at that idea tomorrow.

    A reasonable start made though and my confidence is in a decent place.

    More tomorrow.

    Toto

    You could glue it on with cyano but if the WM has broken that may be the better option unless you use it as a pattern to scratch a replacement from scrap etch. If you do the scratch route take a thin trim fret from one of your many kits, mark the rivet positions then press them using the embosser and then file the edges until the correct size is met. It ain't that scary and can be quite fun when the neighbours all wonder what the loud swearing coming from the shed is all about. :avatar:

    :avatar: they are already used to the swearing Yorkie. Not that I am normally uncouth of course :whatever: just the occasional slip of the feckin tongue.

    Maybe get the chance of a 3 way link up soon with Dundee.

    Cheers for now

    Yes just shout up for a Skype once Dundee feels able. I'm lucky here as you know because my neighbours are reasonably well spaced apart... (oh how I love social distancing) and I can recite particular artistically created sayings without much ado from anyone. Passing ramblers walking down the lane who react to such audio tones are often given a friendly country salute over the gates, they always seem to like country ways... and there I was thinking all they did was to take a walk in the woods collecting nuts and wild flowers. :avatar:
