Progress is slow on these two locos, but I've finally got most of the feedwater piping in place. I've also replaced the locomotive's brake cylinders for the drivers - they broke off while other work was being performed. These are cast metal parts, and snapped off where the mounting pin enters the loco's frame. I managed to drill-out what was left of the larger mounting pegs, then created new mounting pins from wire.
The lifting injectors (black plastic) are from Bachmann's Consolidation (I bought a bunch of cabs to use on all my Grand Valley locos, and they come with the boiler casting, too). This provides lots of extra detail parts, although I decided to use top feed check valves on these two locos. Those parts are from PSC. I used brass wire for the line from the injectors to the check valve, connecting to the injectors with a short section of reamed-out brass tubing, while all of the brass-to-brass connections are soldered.
As was done on my Consolidations and re-worked Moguls, I added the actuating rods for the injectors using phosphor-bronze wire:
By adding a styrene spacer strip on the boiler-side of the backhead from the Bachmann 10-Wheeler's original boiler, I was able to include it on these locos. The spacer allows it to clear the rear of the motor. To facilitate dis-assembly, the backhead is cemented to the cab floor. One of the more difficult tasks during this kind of re-build is ensuring that all work is solidly done, yet still allows dis-assembly - In this case, it's simply to allow the cab window "glass" to be added after the loco is painted. Beyond that, cab and boiler will be removeable as a unit.
Also visible below is one of the lead blocks where the fireman's seatbox would normally be located - these help to counterbalance the weight of the cast metal boiler and the lead-filled air tanks.
The next task will be the air system, including the compressor, cooling coils and piping, and the other air tanks.
