    They look cracking, have you decided what to do about the V1/2 roofs?
    I love the K1 Cattle, but, it should have black buffer housings and coupling plate, like the D1 and D2.
    Have you decided if you want the buffer housings separate or attached to the body?

    My motto has always been “Credit where due”…

    so that’s my thoughts.. :) Well Done!!

    I may now have the missing info to finish at least one of my wagons.. managed to crawl under something similar at the NRM yesterday when no one was bothered looking where I was :facepalm:

    Just have to see if I can replicate it in model form.

    Hi Mate,
    I still have all the black to do, what you can see so far underneath is just primer.

    I haven't had a chance to work out how I might tackle trimming back the underside of the roof. if it was flat I would just run a milling cutter across it but with it being curved it needs more thought.

    Rob,

    I spotted that the black hadn't been done just after my previous post - a case of being optically challenged.
    I've been finishing off printing P6 and Bouch Van parts today, so tomorrow I am going to have a look and check what went wrong with the roof's.

    "think I may have to send my printing to you! :hammer::hammer:"

    I think the great outcome is down to using craftsman resin. It's more expensive than basic but produces much cleaner and better defined prints than the basic resin. I have about 250ml of basic left, and am trying to decide if to use basic for testing/craftsman for final prints or just stick with craftsman for all prints, swopping seems like a faff about, but I suppose it comes down to how many test prints are needed. As I am still relatively new to 3d printing so I do tend to do a few tests, which would waste craftsman. Decision not made - yet!

    Well I’m impressed with the artwork and final results.
    You have surpassed me in both! :thumbs: Although some of that will come down to the simple lack of time I have. Ive done 3 prints in 2 months. Andy

    I have just finished the test build of the Bouch Brake, and now I have a list of changes and/or improvements, very little to the body or roof, but the brake gear has driven me crazy. A rough list of jobs:

    All the brake gear is at least 2mm to low.
    The whole of it is very fragile and doesn't support .7mm wire, this build used .5mm - it needs redrawing and beefing up probably by .5mm all around.
    Look to see if there's a way to define the exact positioning of the 4 sets of brake gear, they are a complete ^&*(^ to position.
    The under chassis supports for the extended end beams conflict with the 3 point compensation they need a total rethink.
    Remove the 2 chassis cross members, they get in the way, are cosmetic and there is precious little room underneath any way.

    The next bit is an aide de memoire for me, there's a specific build sequence needed, which would save some of the horrors this build needed.

    Fit Buffers and Coupling hooks (there precious little room later).
    Fit the central brake assembly, pre wired and with the link to the brake handle.
    Fit the shorter set of brake assemblies, pre wired then their connecting rods.
    Fit the longer set of brake assemblies, pre wired then their connecting rods.
    Fit the short linkages from the central unit to the two sets of brakes.

    Quite a battle plan really with a lot of redesigning need, but, isn't that what a test build is for.

    Just for the fun of it, the brake gear has 14 components and needs 9 x .7mm wire links. Oops a morning after recount 12 .7mm wire links, not 9.

    I haven't done and printing or assembly of models for the last few days, a combination of a lack of motivation and it's been distinctly cool in Leeds which would affect the printing. Instead I have been playing with fusion 360. I picked up a project I started about 9 months ago but stopped as I realised I didn't have the necessary skills to make a decent job of it it's a ballast brake, fitted with a plough that raises and lowers as required. Before Mr Dundee even suggests it, I'm not daft enough to try get the mechanism working. The body is very simple, a few rectangles with bits added on, that was completed months ago, but two things stalled me, the spring hanger and the plough with its mechanism.

    I tackle the spring hanger first and utilised a technique Rob P described to me, that's to sketch on a surface of a model. After a bit of faffing about I got the hang of it and frankly it's dead easy and will be really useful.

    A single spring hanger and with springs attached:

    Spring Hanger 1.jpg

    Spring Hanger 2.jpg

    The plough has caused me a lot of pain, especially as I couldn't find anything about the lowering mechanism, so that bits straight from my imagination.
    I haven't got the plough blades thickness right which sticks out link a sore thumb, but as a first go 5/10. I have a theory how to get it better and that's going to my second go some time later in the week.

    Plough from the side, (the blocked in section at the top is behind the chassis so wouldn't be seen) along with a rear view showing my imagined mechanics and a view from the front.

    Actually, that looks rather good!

    what thickness is it?
    I suspect the lift mech hasn’t changed much, look at a more modern Shark van, big wheel on the veranda that had a rack on it. Turn the wheel, lift the rack with a Paul lock to stop it dropping.
    Although I seem to remember the block it sits on is quite solid due to the force against it by the ballast.
    I don’t think I’ve any photos of ours on the CVR.

    Andy,

    I was trying to make it 1.5mm thick, measure horizontally. The curve of the blade is made up of a series of arc's connected together some are obvioulsy not consistant with others. hence the unsightly bulges.

    Well the redrafting of the plough took two goes before I was happy with it after which rebuilding the rest of the structure went easily. I now have another beastie waiting in the print queue. What next??? no plans so far.

    Having sorted all the difficult bits, I thought I thought I would post some prints of the bodywork that sits on top of it. According to Ian Sadler the V5 was simply a stretched V4 (Jim McGeown does an excellent model of it) the wheel base being increased to13ft but more interestingly he points out instead of the standard NER 2ft 9in verandas one on the V5 was increased to 4ft 9in to accommodate the handwheel. The veranda openings at both ends are the same size, so logically one of the end wall of the cabin must be recessed back shortening the cabin length. This can't be deduced from Ian's drawings, any how that's how I have modelled it, if I'm wrong well I'm wrong.

    So two print, the first a side view showing how all the below waistline bits appear, the other a quarter on view to show the recessed cabin wall. Obviously I have omitted one of the brake end walls.

    Interesting. You can see why the more modern Shark plough vans had one either end, kind of makes it hard without turning the van.
    Look forward to seeing the model!

    New projects the good the bad and the frustrations. I decided the next project should be the alternative Bouch, with one end looking more like a V1 with a birdcage. Dead easy after all I had all the sketches of a normal Bouch so it was just a quick new half side and a few bits, so why not use the existing project and add bits on. What an atrocious idea, after b.... g up the normal Bouch because of changes I was making I simply abandoned that idea, and ended up copying the design to a new project and restarting.

    A new half side and a few bits, how wrong can one be, in the end the list ended up as:
    a new half side
    a clerestory and roof
    a modified main roof
    a new chimney
    a new body end
    and finally four pieces of revised brake gear.
    Everything else will be taken from the original project.

    Well it's finally done and looks as odd as the sketch in Ian Sadlers book

    Screenshot 2022-10-09 105252.jpg

    Screenshot 2022-10-09 102653.jpg

    As an antidote to all the set backs and frustrations with the alternate Bouch I also started fiddling around with a project to design the V2 brake, another curiosity (have a read of Ian Sadlers book) and what looks to me to be a hybrid, its kind of part Bouch, part early brake and bits of everything else. In comparison to the alt Bouch what a breeze, it's done and proved to be a quick easy project and will probably take long to print than design.

    Anyone got 2 or 3 spare printers so I get everything printed?

    Still more drawing with Fusion, Yesterday was the first day the attic temp got above 10c but I couldn't get the printers running as it was a mega family day, typical.
    Over the last week or so I have been trying to improve a set of NER low roofed carriages which I started over a year ago but was never happy with, I'm still not happy with them but a a distraction I have also been fiddling with with a C5 sleeper wagon. It's essentially a C2 high open on anabolic steroids. in O gauge the C2 is 105mm x 10mm, the C5 is 140mm x 45mm. It was built concurrently with the C6 sleeper the only difference being instead of a single side door the C6 has two slightly smaller doors. Why the NER needed two different configurations who knows but it's minimal work to create a C6 from a C5. Fatal last words or foot in mouth - oh dear me.

    Mossy

    The C5 above and C2 below (obviously not to scale).
