[UPDATE 2.18.21]
Here we go with an update... finally.
First off the bat, we've decided that we're going to renew our lease and live in this house for another year, so the Summer 2021 deadline no longer exists. Still need to keep the foot on the gas pedal.
They say that you learn things building layouts, and I can say that I know for any future ceiling layout, I will build the tracks on the wood FIRST (like JerryG did) instead of doing what I'm doing know. It is no fun and a pain in the rear to be laying track, wiring, etc. while standing on a ladder and seeing everything a ground level. Before everything is screwed in, I'm going to have to make sure that the tracks are separated the correct distance all the way around (hard to see at this angle) and that track runs that seem that they are dead straight (they're not) are not kinked.
Took these photos over the past two days. Cut and laid down the cork two weekends ago and then this week is to put up the track.
