What are TwistTies used for?
We developed TwistTies as a method of building a curved turnout of unknown size. The approach to using TwistTies is closer to traditional handlaid track in that rail is spiked in place onto wood ties. Etched guidelines are engraved onto the surface of the ties to aid in keeping the geometry accurate. Pre-drilled spike holes are provided to also aid in rail alignment.
Other than the throwbar tie there are not PC board ties used in a TwistTie built turnout. TwistTies are very flexible and can be curved into any radius but still maintain standard frog geometry. A #8 frog used in a TwistTie can be formed with a #8 PointForm tool regardless of the radii it has been curved into.
