Is there a Frog Juicer wiring diagram for a single crossover?

Is there a Frog Juicer wiring diagram for a crossing?

Wiring a crossing for automatic polarity control requires 2 Frog Juicer circuits. (Two single Frog Juicers, one dual Frog Juicer, or two circuits from a Hex Frog Juicer.) Two of the frogs diagonally across from each other can be un-gapped. The other two frogs need to be gapped and the polarity controlled with each frog ... Read more

Is there a Frog Juicer available to control “live” frogs?

The Frog Juicer was developed to only work with isolated frogs. However, several users have used the Frog Juicer with live frogs by making the following simple modification. Paint the inside of the rails where the points contact them to insulate the points from the rails. Attach an output from the Frog Juicer to the ... Read more

Is the Rail Roller pre-calibrated to produce different radiuses?

No. Since the Rail Roller can be used for any scale, there are too many combinations to reliably pre-calibrate the tool. You will quickly find this isn't necessary anyways as the tool is straightforward to adjust and use.

Suppose some of the outputs of the Frog Juicer are used as an auto-reverser, and other outputs are used to control frog power. Will there be a problem with a multiple unit locomotive clearing the turnout before the reverse section is entered?

Symptoms For example, there is a crossing on one end of a turnout and less than 12 inches from the other end of the same turnout to the isolation gaps for the reversing section. The crossing and the turnout are located within the reversing section, so a multiple unit locomotive can start continuously switching polarity ... Read more
