Modifying The Hornby Turntable, Part 3.
The method for rotating the Turntable uses a "Geneva" Gear. In practice this has a "lump" on it which drags the table around 1 section. There is then a pause while the gear rotates until the lump engages again and move the 'Table on. The pauses give you a chance to stop the motor, and solves the alignment problem.
A downside of this is that the 'Table moves a section at a time, and cannot turn without stopping at every outlet, and on the R.410, which has fewer outlets, it stops in between them as well.
Another downside is that there is a large "ring" around the Turntable. Hornby make this look like Chequer Plate. (I have painted mine "Concrete" after sanding the moulding down a bit. It isn't perfect, but it does work...)
Hornby has modelled an "Under Girder" design. A pity they didn't copy Hornby Dublo, whose 3-Rail Manual Turntable was an Over Girder Type.
The other "problem" is the raised area with the "office" on it. This is necessary to accomodate the gearing and motor. (I intend to cover most of the raised area with a brick built Water Tower. Possibly using the Airfix/Dapol Tank.)
I am currently thinking of the Ranlaugh (?spelling!
) Bridge Yard outside Paddington Station as a basis for using the Turntable, as in Model Rail Magazine in 2011.)
More Photos.
More painting and trial fitting...
I have made a "Concrete" Buffer Stop for the exit position in line with the Raised Area to protect the Water Tower (Not yet built!).
More Concete Painting..
Testing...
Painting the track bases, etc. in Sleeper Grime.
The "Finished" Job. (Water Tower still to be built, but that is another story!
)
Weathering is by a mix of Black, Brown, White and Green Acrylic water colours from a local Art Shop.
