After the mess
With the Evostik cleaned off the floor more of the cassettes could be assembled. At the front are three loco-sized ones, properly weighted down while the glue sets. The long cassette to the back only has one of the aluminium angles glued in so it can be left to set. It is much easier to check and guarantee the correct gauge over the 1.2 m length if both aluminium strips are not able to shift on the glue.
