a Cornerstone 2-rail Turntable to 3-rail
Many thanks to Pierre GILLARD who inspired me and led the way to to make this kit conversion.
It took me about 15 hours to complete the conversion including the mating tracks and saved me over 200 Euro, compared to buying a Märklin turntable. More fun, more special, less cost!

I started to paint all the parts in the kit as follows:
Humbrol #110 Natural wood - Ground colour for the deck
Humbrol #113 Rust - Weathering of pit, rails & bridge structure
Humbrol #33 Black - First drybrush layer on deck & rails. Second layer drybrush on the house and pit.
Humbrol #64 Gray - Ground colour for the house, bridge structure, motor & support bars
PollyScale F414317 Concrete - Ground colour in the pit.
Adding Roco code 100 rails to the
Since I'm using Märklin M-rail I need a rather tall rail profile to get the same height on the deck as on the mating 5106 modified track sections. Best for this purpose was a Roco code 100 flexitrack section.
I cut away the rails using a razorblade.
Next thing was to solder feed cables from both of the rails.
After that I simply just glued them on the deck using CA glue.
I didn't care too much about getting the exact distance between
the rails, since they were sitting quite tight in the space
for the rails in the deck.
Building the kit
The rest of the kit was built according to the instructions that came with the kit. Not so many parts, very easy work really.
Cleaning of brass contact rings and
It is necessary to clean the contact rings and springs with Isopropanol, or Acetone to achieve proper contact after the assembly is completed.
Converting mating M-tracks
The track sections which will interface with the turntable have to be somewhat modified. This is necessary since the pit sides require the rails to be 6mm longer than the track bed on a normal 5106. I simple broke off the spring contact on one side of the centre conductor rail. Thereafter I fixed it gently in a skruvstycke and used a vinkelslip to cut the trackbed. After the track bed was cut away I finished the work by griding manually with a fine grinder.
