    The plan has been carried out and now drying, not as neat a job as Mr P would do but at least I am trying!

    I have just started practicing with crystal clear on a duff body, what a %^&*^% job and so many window to do, I hope it will get easier otherwise I'll be stark raving bonkers by the time they are all done.

    There is a knack to it and it does get easier as you practice. If it helps I use a cocktail stick with the point cut off and a flat filed on it - think wooden chisel point then I use that to apply the crystal klear (or Glue N Glaze in my case). I hold the cocktail stick almost horizontal to the opening and then using the flat that I have filed I pull it across the window. The flat seems to give a bit more surface tension to grab onto while stretching the glue across. It does sometimes take a few attempts on each opening

    Rob,

    I have been using just a standard cocktail stick, so next o I will modify one in line with your suggestions. What has surprised me is the quantity of glue needed, or perhaps that's just me being clumsy!

    Dual fitted NER Class M1. Vacuum brake pipe on left hand side and air brake to the right, fittings colour coded red or white to indicate use.

    Thanks Tom,

    Would the Westinghouse still be painted white even when not dual fitted?

    The few end views of coaching stock I have access to from the period all appear to show the pipes as a dark colour, so I would rule out white.

    correct. And if anyone was wondering (although somehow I suspect you all know) Red is for Vac braked and white is a through piped vehicle. (Ie the vac can be connected to the next vehicle and so on, but the brakes on this item with a white pipe as not connected and handbrakes only, or may be airbraked instead, in which case you may have 3 other pipes, white red and yellow. But that’s a bit above my skill level and even I have to ask which is which on that? One is main, one is control and I think White was later discontinued)

    Tom,

    One issue here. A white pipe on Air Brakes is not a control pipe. To control, a loco will have two pipes and will be red and yellow.

    Air Brake (Resevoir) - Yellow

    Air Brake (Main) - Red

    Air Brake (Through Piped Only) - White

    Vacuum Brake - Red, or bufferbeam colour

    Vacuum Brake (Through Piped Only) - white

    Electric - Orange

    Steam (Heat) - unpainted

    Hope this helps clear up.

    also asked a pal who works on wagon shunting and Westhouse was only a maker, never a type. we have only ever had unbraked, handbraked, vac and air brakes stock (some obviously were later dual brakes but only one system would be in operation at any one time.

    Andy,

    I heave read some where that at grouping over 90% of NER stock was either unbraked or Westinghouse only (air if you want) and they also has the largest fleet of wagons and coaches of any of the pre-grouping companies. Ut took to well into the 30's before the LNER eliminated they finally the Westinghouse brake system. Only the stock which was used on the East Coast Mainline was dual fitted, M1 no 621 is famous as being part of the NER stock which took part in the 2nd round of the "Race to the North", given the relatively low educational standards of the workers, colour coding makes sense to me.

    Andy,

    As Mossy has accurately described, NER express and some shunting locomotives had by necessity to be fitted with both the Westinghouse air brake and a vacuum brake for use with their own stock and East Coast Joint stock respectively,
    This is a diagram of the Westinghouse system reproduced from the NER staff handbook on the use of brake systems. There is only one pipe between the locomotive, tender and coaches. What you describe may well apply to modern air brake systems but not the Westinghouse system as used by the NER.

    Tom.

    More experiments without a great deal of success.

    I've never tried to use krystal Clear to create windows, so why not give it a go. Rob P kindly provided a video of how to use it he had made and also more advice on making a suitable tool to apply it. Well 3 separate attempts over 3-4 days, each trying numerous times results dire. The best results I got were not dissimilar to the convex/concave mirrors in old fairground attractions, thin at to start, fat and the end, any reduction in material used and the window failed. Rob, does this material increase it's viscosity in cold weather, could that be the reason? Another attempt will be made next week in the warmer weather. As a standby I have ordered some transparencies as an alternate solution.

    The second experiment, currently also failing but being retested is to try print a roof in 2 sections and then join them seamlessly. Yes I could probably have printed the roof in one piece using my big printer but as a test I used the mono 2. Attempt 1 was rapidly thrown in the bin not fit to be seen, part 1 of attempt 2 in currently printing. The idea when they are suitable is to lodge one end of the roof under the birdcage and use a pair of nemodium magnets to hold the opposite end in place. The tab on the short end is over long so will need cutting down but better to long than to short. More when it is fit to be seen.

    Oops forgot this:

    roof 3.jpg

    Forgot to say, one half of the roof was printed using the save as a mesh option, the other half using the long winded export as an stl method, the results are very different. The export section is narrower and has distinct lines running along the length of the piece. Not something to be repeated.

    I thought that was just me and my machine with the very slow export to STL. Yet it will import in less than a second. as comparison, the same file could be exported in 123d in around 15 seconds.

    It’s very odd!!

    Andy not sure this works with an stl, but with a body use Save as a mesh, it takes 2-3 seconds.

    Highlight the body and right click, select save as a mesh.
    On dialog that pops up, format stl, unit millimetre and refinement High, click ok
    Second dialog box decide where to save it.

    If you look at the size of the stl, it will be 10-15 times bigger than a export as stl
    A far better quality stl is the result

    I can't say as I have used Crystal Klear mine is Glue 'n' Glaze but I would be surprised if there is much difference in them. Mine have always been done in my workshop which is always at the same temperature so I have no experience but I suppose it might make a difference. The windows that I have glazed with it are never as perfect as using glass slides or clear perspex but small windows have proved quite easy to do.

    Thanks for that Rob. Will be doing another experiment later this week for now focusing on joining roof sections.

    Or far too cold .........

    The faster time for Save as Mesh vs Export is your PC is doing the conversion, rather than using the cloud service which puts you in a que.
