INTRODUCTION AND GUIDE FOR USING THE CROSSOVER CONVERTER OPTION.
"THE "CROSSOVER CONVERTER" is an incredibly simple and inexpensive upgrade to a turnout option jig that instantly extends it to be able to construct accurate and precision crossovers as well!
ESPECIALLY NOTE THAT YOU ONLY NEED ONE TURNOUT OPTION TO BUILD BOTH TURNOUTS IN THE CROSSOVER. AND THE SAME OPTION AND CONVERTER WILL BUILD CROSSOVERS OF BOTH HANDS (L & R).
This guide is a work in progress. The current pictures are temporary and obviously "Photo-shopped" from other illustrations and should not show tieplates at these earlier stages of construction. Please send in any problems or comments for correction to the ACCU-TRAK elist. All the existing instructions for turnout building in the turnout building generally apply to building crossovers. We will confine ourselves here to the use of the converter jig and any major differences.
NOTE: The converter may be used on either the short 19" or the long 38" base. In the former case just use the jig to build exactly half of the crossover, then assemble the two halves on your layout. The rest of this guide will describe how to build a crossover on the long base. The process for building a half crossover on the short base should then be obvious if you need to do it that way.
As per the usual turnout construction, the first step is to make sure that the plastic base is laid on the base first. Also, it is possible to use the straight edge side of the base, to keep the entire crossover tool and construction in straight-line alignment during the whole of the construction.
Begin by laying the left-hand end ties of the crossover using the regular option tie base parts. At this stage, only lay the regular turnout length ties up to the point where the double length ties start.
Remove the curved side of the tie base option, and substitute the second straight tie base side using the two double length two cross pieces as shown.
Now lay the double length ties only up to the midpoint of the crossover.
Using the newly laid double length ties and the alignment edge of the base, reverse the crossover converter parts as shown, so that they are correctly positioned to later lay the ties of the other half of the crossover
However, because of the overlap of the curved tool side on the already laid double length ties, it is better not to lay the remaining double length ties at this stage, but to instead first lay the second set of regular turnout ties. So replace the curved side of the normal turnout base tool.
Now lay the regular turnout ties of the other end of the crossover, again only up to the point where the double length ties start.
Then replace the curved side of the turnout base tool with the second straight side and the two double length links.
Lay the remaining double length ties to complete the tie base.
With the tie base complete, the tieplates can then be laid using the regular turnout tieplate jig, using the appropriate tie base tool straight side in each of its four possible positions.
