    Now printing it upside down (suggest printed flat, 8mm Z offset) - top of wagon nearest to the build plate, with the hopper doors printed seperate to avoid the vacuum effect.

    Ah, well, if you have that much free time, I’ll send some plans over :avatar:

    Sat again looking at a number of photos of the blessed wagon I’m trying to finish, but all seem to have missed the relevant detail I need. I have a pal who works on restoring coaches and wagons, but he’s on holiday till tonight, so may pick his brains.

    maybe I should have picked an unfitted wagon rather than Vac braked!

    Andy,

    Same problem I have with the axle box for the S4, plenty of photos, none of which show the details I need. I suppose most photographs would rather photo the whole wagon rather than just specific detail. Amazingly there is a photo of the axlebox/w iron etc but even that doesn't help.

    The S1 hopper is progressing nicely with a few hurdles along the way. chiefly drawing the running plate which needs a cut out to accommodate the hopper. All 4 sides of the cut outs need chamfering to allow the hopper fit. What a ^%$£*^%, there must be an easy way but frankly I bodged it. All that's left to do is the brake gear - easy said but....

    Well another one finished. I'm not 100% certain of the accuracy as the sketch I was working from lacked a lot of definition and detail and the only 2 photos I could find are rather dark. All up my version of an S1 Ironstone Hopper. which is now definitely on my print list.

    Half a body and chassis

    The end brakes (these are the parts I am most unsure about). Strangely the brake shoe appears to press down on the wheel at an angle of about 45 degrees rather than acting horizontally against it.

    Hi Mossy - great progress.

    I believe the contact angle doesn't make any difference, as the brake shoe pivot point appears to be aligned with the wheel center.

    Hi Paul
    I couldn't see why it would work as you say the pivot is aligned with the wheel centre, it just looks unusual. The history of these little wagons is all a bit vague but from what I have manged to find out the first examples seem to date from the 1860's with further batches being built up to the early 1900's when in theory they were to be replaced by the S4's but the clearance height to loading screens and tight curvature of the sidings in the smaller ironstone mines meant they had to stay in service. The only two photos I have found show examples in BR livery as engineering stock, so some examples must have been pretty long lived. Three of my relatives worked the last shift at North Skelton mine (the last to close in 1963) sadly they have all passed on so I can't ask them either, not that any of them worked with the wagons, in Cleveland dialect one was a banger the other two marra's (an explosives miner and two 'miners assistants' in truth labourers).

    What a small world, Chris and I bought and renovated an iron ore miners cottage in the village of Brotton between Saltburn and Whitby (not far from North Skelton which was the next village over on the inland side of the village).

    We were less than half a mile from Lumpsey mine which closed in 1954. There are quite a few remains above ground which we walked a few times.

    Rob,

    Its even smaller my mother was born in Magra Park (or Margrove Park to use it's posh name) almost all her siblings either married mine workers or worked in mines, just to name a few you would know and I'm sure of- North Skelton, South Skelton (basically Brotton), Boosbeck. Spa, Aysdale Gate, Skelton Old Shaft Skelton Park and Kilton. One of my Uncles was seriously injured in Kilton by a roof fall, his rescuers were all awarded medals for his rescue, he was a marra. Also I'm sure I have mentioned it before, I got my first kiss in Brotton high street (about 1964 or 65), about 1/2 hour later later I went back to Guisborough where we lived, and the first words from Mum were why were you kissing .....(I won't mention the ladies name). We didn't have a phone but the Cleveland jungle drums were that ..... effective!

    Hopeless with dates it would have been 66 or more likely 67, not 64-65 I was still in short pants then,

    A few days ago I manged to get access to a couple of excellent photos of the S4 hopper and decided to review my model against them. What was immediately apparent was I has drawn the chassis as if it was a standard 11" x 4 1/2" wood chassis, it isn't, it's an all steel chassis. Both the dragbeam and solebar needed reworking, and after numerous restarts and reworkings I finally got to a state where I was happy, but then I reviewed if the bodywork support legs would still slide over the chassis - nope, oh botty! After having been mind bending over the chassis changes I wasn't looking forward to this next bit but actually it was pretty easy so the S4 now looks like this:

    I have also found a potentially better diagram of the S1 in the NERA archive so I have ordered a copy and will review that model when it comes.

    In amongst trying to solve Andy's roof problem and messing with the S4 chassis, I have been doing a load of digging to try find a proper diagram of under chassis end brakes. There is so much info available in the NER Expresses and they are all available on-line to members, I decided to trawl through every copy and develop a register of every article / diagram covering wagon stock and found an elusive diagram of the brake gear. If anyone would like a copy just send me a message.

    So revamped and update brake gear for the S1 looks like this. The blue items will be replaced by .9mm brass rod.

    I've been playing again. I really fancied another hopper wagon and found a short article and diagram of an R3 Coke Hooper, first built in the 1880's. More interestingly it was described as being a P5 Coal hopper fitted with two additional raves. I also have the diagram and article on the P5 and yep other than the raves they are identical. Twinkle twinkle my little brain, model the R3 and its some very simple changes to also create an early P5 (both have wooden buffer housings - a very S&D characteristic and end brake levers). In fact it was the R3n coke diagram that I used to model the P1 Ironstone hopper brak gear. Well here they are:

    The R3 Coke Hopper

    The P5 Coal Hopper

    I don't have any plans to print either just another Fusion 360 drawing excersie,

    Forget wheels, how this happened is beyond me, I'm blaming a bug in fusion 360, it certainly couldn't be my fault.

    Left the blooper, right corrected.

    You are a better man than me, admittedly I'm looking on my phone but I still can't spot the error/difference.

    Rob,

    The left end support is nearer the end post than the corresponding right support, it's only a few mm but its there.

    It shows up better in this print which is where I first spotted the problem. There are holes either side of the coupling mounting for side chains, but look at the distance from them to the end supports.
