After an extended absence(!) from my workbench I'm now back working on these two.
My own loco is having an open cab, the owner of the second loco has requested the closed version. The body baseplate is first bolted to the main frames, a thin layer of grease between the two stops any embarassing solder accidents. Then I tacked the cab front in place, followed by one side;
I left the etched detail parts inside the baseplate in place while I made up the cab, to give the baseplate additional strength.
The second side can then be tacked in place, and the doors fitted. The doors have etched tabs which feature holes that line up with the handrail holes in the cab sides;
I used a taper broach to line them up before tacking.
I then tacked the cab rear in place before unbolting the assembly and finishing off the joints.
Here's the two cabs back to back;
I had a few problems soldering this assembly up... I simply coudn't get solder to flow into the joints. At first I thought that the element in my iron was on its way out - then I found a lot of corrosion inside the tip body (I use an Antex iron where the tip fits around the element). I thought that a fresh tip would cure the problem but I still coudn't get enough heat to make a joint. Eventually I removed the tip and fitted a larger one and that solved the problem. I was trying to use a 1mm tip, for a neater job, which wasn't holding enough heat or transferring it to the job, going back to my usual 2.3mm tip cured everything! I live and learn...
Paul.
