Still waiting on the new gearboxes, so, some of the "easy" work.
I hung a cross compound air pump on the smoke box front, ( Sumpter Valley #250, 4th loco back in the picture, had the compressor there ).
With the front mount Bell, it looks too crowded. My next "work session", first thing, move the compressor to the Left hand, "Fireman's" side, and repair the damage to the smoke box front.
I got the side rods, and the piston rods installed. I need to adjust ( shorten) the crosshead guides, and build, and install, the supports for them. I also got the power reverse unit installed, and started on the steam supply pipes, for the rear engine.
Once the compressor is moved, and the supply pipes are done, it's time to complete the frame modifications so I can install the cab floor, and begin the back head details. Somewhere in the middle of all that I have to mill the top of the frame castings, for clearance for the universal drive shafts that will allow the motor connections to the drivers.
No, there is no prototype for this locomotive. Then again, there is no prototype for the locomotive builder, Sag Harbor Shipbuilding and Dry Dock Company. I am using my own limited knowledge, the model of the SVRY #250, and the model and photos of Sierra Railway's #38, as "references" to "what, and where".
I have stumbled onto the first of what will probably be many *problems*. The shafts on the main driver counterweights, aren't long enough for the side rods, drive rods, AND the eccentric for the valve gear. Looks like the only way out of this one, is to remove that shaft, drill and tap the counterweight, and insert a new, longer shaft. ( I really do want Walschaerts valve gear on this loco )
Close-up of the running gear, the Trailing truck, and the Power Reverse unit.
a :o clear shot :o of the right hand side, and the first part of the main steam pipe installation.

We always learn far more from our own mistakes, than we will ever learn from another's advice.
The greatest place to live life, is on the sharp leading edge of a learning curve.
Lead me not into temptation.....I can find it myself!
