....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.......
