Welcome aboard Steve, it's always nice to see working models.

To help with your questions do you have a copy of TTSM so that we can point to items in it?

Engine plans for the Britannic are at http://hmhsbritannic.weebly.com/plans.html

The governor was drawn in this post http://titanic-model.com/dc/dcboard.php?az=show_topic&forum=100&topic_id=49792&mode=full . It is nothing like a flyball governor at all, it uses the inertia of a measuring element mounted on an arm that swings up and down.

A physical starting platform suits an old riverboat and it was revived with turbine engines but for reciprocating engines it is nothing more than an area of the plain engine room floor that is the focal point of the controls. The term is figurative rather than literal. In the Titanic's case it is the floor space on the lowest floor, beside the HP cylinder and between the two engines. The engine controls are hung on the side of the engine and are marked in a picture on pg315 of TTSM-I. The throttle wheel pushes a lever rotating a rod along the engine to another lever that pushes the valve open. There is a large main throttle and a small bypass used for maneuvering. The reverser handle is hung on the side of the reverser. This thread http://titanic-model.com/dc/dcboard.php?az=show_topic&forum=100&topic_id=49609&mode=full points to textbooks about the reverser, specifically the responses to replies 21 and 24.

In your third close up view of the end of the engine you show a valve on the top side of the cylinder. This is the top tap point for an "indicator" test. Google steam engine indicator or look in an old text, it's a mechanical pressure recorder with a drum shaped chart. The pipe runs down to a matching valve at the bottom of the cylinder for recording its pressure too. The indicator is attached near the top valve when an acceptance or maintenance performance test is run. Beneath the end of each cylinder is a light linkage that pulls a driving string that rotates the indicator chart with the cylinder stroke. The area of a chart of pressure versus stroke shows the power being developed and reveals mis-set valves, leaking rings, etc.

The dome bottom tub that you had run that indicator tap pipe to is a steam trap for letting condensation out of the cylinders at starting. There are several of these and they connect from their own valves at the points where water can collect in the cylinder, valve and passages.

Two other light linkages beneath the cylinders are the oiling tubes to the crossheads and the drive for the revolution counter at the front side of the engine.

In your screenshots, the one with the semi exploded isometric view showing all the rooms looked very interesting. What software are you using?

Bill
