I pulled the springs out of the turnouts this morning, then started the slow process of gluing the track down. I used Aileen’s Tacky Glue, based on many recommendations, as it dries more quickly than some white glues, but not so quickly that adjustments can’t be made.
I laid one section at a time, to ensure good, tight connections, and weighed down sections with books while the glue dried.
To fill in the gaps under fishplates and near turnouts, I used some Peco SL-308F ties, slipped under the rails. I ordered another package of those a few days ago, as I will need them before gluing a couple of sections (the short length leading into the turntable, as well as the rearmost spur). I should be able to start wiring everything up while I wait for the spare ties to arrive.
