    .....Back in the workshop. I have added the vacuum tanks, some delay valves and the pipework to the brake system. Just a bit more to add when the boiler is fitted up. The tanks were made from tube and plate!

    Attention turned to the cab. The cab etching is nearly correct (!) but did need a few holes and vents filling that were in the wrong place. The strapping and cab window sliders were added and it was folded up.

    Stunning work as always, if I may be allowed a comment about brakes and specifically WHR brakes. I don't think 87 has been converted to air at all, from the WHR/ Festiniog operational matters all passenger rolling stock and at least some WHR goods stock is vacuum braked as are all the locos, I can see no sense, nor a pump, to change 87. I wonder if differences are more to 87 being Cockerill built in the 30's and the rest by Beyer Garrett in the 50's.
    Regards

    Sorry Martin it was my mistake. I was a bit confused by the absence of a Westing house pump or similar. I saw a pic of the underside of 87 in Dinas and I mistook the very small vac cylinder for an air brake item. The model is actually of 138 (I changed loco early in when someone pointed out the kit was nearer to 138 than 87, it hasn't turned out to be the case!)

    Does anyone have a picture of the cab interior of 87, 138, 143 or similar? I'd like a bit more info about what the controls look like and how they're arranged. And what's in the rear of the cab.

    Thanks

    ....moving on, the kit has very little in the way of cab interior parts, so I sent a shopping list off to Laurie Griffin. While we await a bag of goodies, and with Brexitcast on the BBC Sounds app, I decided to fix some chequer plate to the footplate. A very helpful Aussie bloke called Brian Millar contacted me through Messenger. He offered some etches for sandboxes and oil tanks. He also offered to make some chequer plate etches as I had discovered that the footplate of 138 isn't plain, a week later they arrived from Queensland. Massive thanks Brian. Also about half way down the overlays change pattern from old fashioned diamond to a modern chequer pattern and Brian had taken care of that too.

    Here's the cradle with the cab fitted up. If you look carefully you can see where the pattern changes, here:

    Still waiting for cab castings I made up the sand boxes, oil tanks, lubricators and lamps for the front panels. Also the fromt deck has more Chequer plate.

    Next some tedious lube pipe activity..........

    ....I have caught up the bunker end of the garratt model, and all was well with that. I have also made the linkage from the lever attached to the expansion link pivot on the lubricator side of each unit to the lubricator operating arm below the footplate. In this way it will gently reciprocate.

    At this stage both units are complete and ready for paint, so on to the cab.

    The backhead was made taller, by soldering on a strip of scrap whitemetal, and thicker by soldering a strip of brass round the perimeter. Some improvements were made to the firehole door.

    The cab roof on 138 is wooden with a canvas skin. I made the model roof from 0.2 mm brass sheet so I could get the compound curves made easily. Guttering was added, a sliding sunshine roof and some lifting eyes. The underside of the roof was covered in venir to represent the planking.

    I think it worked out well as the planking strengthened the paper thin brass and the roof now fits nicely like a box lid.

    Next I think I'll have a go at a the boiler/smokebox and firebox. I suspect I'll be scratchbuilding.......

    Sorry just upgraded my Flickr account and all the pics have become massive. Will sort for next post...

    ....well a big push to finish the thing. I thought the boiler was pants for a variety of reasons. The smokebox was ok, so I fabricated a new boiler and firebox and grafted them together.
