Just line modules, he said.
Last weekend we had a construction meeting. Dirk was so kind to let us occupy is garage and workshop. A few days before I brought my workbench and some power tools and Dirk prepared all the parts we would need.
Dirk hand built a jig to build curved modules and we used it to build curves with a track radius of 160 cm and an angle of 30 °. My son and I built four curved, three 90 cm straight and a 45 cm straight module.
