    Always impressed with your skill and attention too detail. Almost seems a shame to paint them. Hats off to those who build these hand built locomotives :thumbup:

    As is the way sometime when kit building, one step forward equals one or more back. Because I had sent the chassis away for painting I was unable to test fit the chassis to the body and when I got it back it wouldn't fit....

    In the end I had to file of the edges of the cylinder covers front and rear to get it to fit in...which sort of ruined the paint job!

    It does look good when put together though. I did also note that the rear body fixing is sitting a little too low so I need to sort that the get the ab and tender tops to level up.

    I took it for a run on Saturday and it ran fine but it's not too keen on test track curves....

    Could you not touch that up yourself ?

    I could but Warren said that he will give it another blow over with some cellulose when he gets the body to paint.
    To be honest it is completely hidden inside the body anyway so you would only see it if you take the body off.

    Meaningful contributions to the forum have been infrequent of late, mainly due to life getting in the way of much modelling.

    I have been doing some though and much of it repeating what's gone before in terms of building the tender for the second coronation. Oddly this one has fought all the way and I am going to end up doing some scratch building to make the insides of the tender acceptable.

    Needing some light relief the other night when i didn't have much time to devote to the ill fitting tender, I built up the pony truck which went together just as the last one and then I started on the bogie. It was down to final detailing when a moment's inattention had me melting one of the bolster castings. After some muttering I decided to scratch build a couple of replacements and having a borrowed copy of the Wild Swan"LMS Locomotive Profiles no 11 The Coronation Class" to hand I had a look to see what the real thing looked like as opposed to DJH's interpretation.

    This crop from one of the photos in the Wild Swan book shows the shape of the bolster.

    Next is a crop of the accompanying GA drawing.

    These are the replacements alongside the remaining original bolster casting.

    Then they were fitted to the bogie.

    A big improvement in my opinion and almost worth melting the casting.

    Those that notice such things will have also noted that the bogie end frame in the first photo has a quite substantial plate over the top whereas the DJH bogie has just the edge of the etch.

    The top edge of the front frame as supplied is clearly visible in this shot of the bogie on the one that I built last year.

    On this one having done the research it seemed worth adding them and I must say that although not perfectly replicating the the prototype it is a big improvement to the overall look of the bogie. Sadly you won't see that much under the streamlined casing on this one but I have a Princess Royal and a couple more Coronations in the pipeline so if they are not included in the respective kits I will add them as I have done here.

    Other pressures are still keeping me from the workbench but I have managed to finish the tender but it wasn't without a fight. For some reason the coal space just wouldn't fit as the one that I built last year did and in the end I had to scratch build a replacement fire iron tunnel because the cast one just wouldn't fit.

    There are some shots of the other one earlier in the thread but this is the replacement. I put my Warco guillotine to good use in making it.

    I have made a start on the loco frames but they aren't assembled just yet.

    Hi Rob
    Just catching up on a few topics

    Well done with the reworks on is latest build
    The bogie modifications are a major improvement over original.
    The scratch built out riggers are a vast improvement over the DJH parts :tophat::tophat::tophat:

    And the additions/rework to the tender are nicely done the folding machine looks like a really worth while tool as a workshop addition.:thumbs:
    Was the fire iron compartment casting poorly done/miss shaped or the like:faint:,
    I’ve had a couple of issues with castings like that before having twists and as they are solid you can’t do too much with them and as they don’t have a flat surface to be able to heat them and get them to reset on a flat surface it’s very frustrating.

    Hi Chris,

    No the casting was perfect, it was just that the etch didn't fit the same as the first one I built and when fitted, the angles were different so the casting had big gaps around it.
