1. The new rods now come in multiple sizes for different gauges:-

        SWRDH  for HO and PROTO:87
        SWRDN  for HOn3,
        SWRDM for HOm
        SWRDT  for HOn2.5

In addition, the fret parts can be used for "N" and "FiNe", with a little extra adjustment.  Please call or email for advice.

2. The Mk II kit parts comprise:
    An appropriate size fret containg 4 sets of double bar divided rods.
    6 precision pre-drilled insulating bars.

To use the optional second rod as per the prototype, two of the pre-drilled insulated bars should be cut in half, to make four half length bars. 

Note that there are now 8 holes in the full length plastic bars. When the rod is used full length, only the 4 holes adjacent to one end should used.  The metal bars can be removed from the fret merely by bending them off.  The tabs will snap away without the need for aditional filing or clean up.

Assemble the metal rods onto the plastic bars by adding a tiny amount of ACC or epoxy to the appropriate holes, then press the rods fully home with grips (pliers) using a crimping action to clamp the rods down against the bars.  Use the plain end bars for the operating rod and the hook end bars for the dummy rod.  Wait for the glue to cure before proceeding.

If you are using the option dummy rod to operate loose heel switch rails, then it is necessary to drill a small hole (#75 drill)  in the base of each switch rail centrally between the dummy rod ties. A Dremel is ideal for this task and the hole should be drilled as close to the rail web as possible. Use proper safety eye protection whenever drilling. The dummy bar can be dropped in to place with the switch rails held apart. Then the hooks will snap into the holes, if they are eased carefully over the rail bases as the switch rails are moved back together.

Here we see the assembled switch rods in place beween the switch ties. The hooks hide the drilled holes completely.  This example is an original style Micro Engineering Switch, but most good quality RTR and hand laid switches can be used just as easily.

The width of the plastic bar is a smooth sliding fit between the blade ties.  Note that the plastic bar is only half the height of a standard plastic tie, leaving space to glue a single cosmetic layer of ballast. One of the spare holes in the operating bar can be used for the operating wire coming from a switch machine or hand throw. Or drill a new hole if more convenient.

For an even better appearance, cut small strips from the self-adhesive paper label material provided and press them down over the insulating gaps. These both hide the gaps, and also simulate the central bolted joiner strips on many real protoype rods.

Color the paper and the rods a suitable dark grey or brown as per your prototype. We have deliberately left our rods plain in this instance, so they show up in the picture.

 

Finally add the layer of ballast to hide the supporting insulating bars. The switch rails have been left uncolored for contrast.

These operating rod kits are intended for use with our own switch kits, upgrading good quality RTR switches, or for handlaid switches.  With a little care and adjustment, they can usually even be added to greatly improve existing laid switches.
