T-Trak Track Alignment Gauge

thingiverse

**T-Trak Track alignment gauge** This is a gauge for aligning tracks to the T-Trak module standards while constructing modules. The standards call for the centerline of the front track to be 2" from the front edge of the module, the tracks to be placed on 33mm centers, and to overhang the ends of the module 1mm. This gauge can be clamped to the end of a module, with one edge even with the front of the module to achieve this position. Several years ago I fabricate this style of gauge for my own use from sheet styrene, this is a 3D printable realization. There are four versions here: * The normal one * A version for Kato Unitrack double track pieces that omits the center spacing piece. * A test version without most of the clamping surface. This prints more quickly, if you want to check that dimensions are correct on your printer. * A version with three track locations. Useful if you add a third track, or to set the three allowable position used in my narrow single track modules, Print a pair to clamp to both ends. The gauges are symmetrical and can be used for either end. 7/28/19 added track placement gauge. This is a simple gauge for evaluating track position on already constructed modules. Reliefs added next to tracks to allow for ballast. T-Trak is a popular standard for table top model railroad displays. See http://www.t-trak.org/ for more information and http://ttrak.wikidot.com/ for example modules. See http://ttrak.wikidot.com/hillside for an example of modules using the 3-position single track concept.
