Midland Class 800 2-4-0
2mm Class 800 Loco construction
This class of loco has outside frames, so clearances will be tight. I have therefore decided not to start with the chassis, as would be my normal process, but to make a start on the main footplate & body work, so I can check clearances as I progress.
The main outside frames and footplate assembly was carefully folded to shape. I found that the artwork design over estimated the curved splasher length, so I have opted to cut these into three sections. There will be a joint in the footplate at the top of the curved section of each driving wheel, but this joint will be filled in and hopefully not be evident later. They can be seen clearly in the running plate view below.
The cab sides have a simple pattern of rivets, that in modern etches would be half etched in. The designer in this case has half etched them from behind, a sharp scriber, is used to push the rivets out - the pictures explain the process far better than words. The cab sides and spectacle plate are then soldered up, keeping everything square.

All done, ready for assembly.
The basic cab assembly is now test fitted in place, after carefully filling back the inside for the rear splashers to provide clearance, making sure that all sits centrally on the footplate.
The boiler was first annealed to allow it to be rolled - a tricky job at the best of times, but I do find that the annealing helps. The spectacle plate has an etched line to show where the boiler should fit, This can be seen in the next picture.
holding the parts in place shows that there is excess material below the fire box that will have to be trimmed back. I have temporarily tacked the boiler in place on the cab front to measure and file back as required. The boiler will be removed later during chassis assembly to cut away more material to provide clearances.
This represents a full day's work, and is for me very fast progress. The next task is to look at chassis and gearing etc. But right now I'm going to have a quiet drink!
