Tonight I finished working on the arched wall and installing it onto the layout. I know the back of my legs are going to be killing me tomorrow, since I can already feel them aching. (Leaning over the 1st two level tracks to install)
I installed the N scale Architect sheeting into the openings I wanted bricked in, then I cut a 3/4" plywood template to go into the arch. This allowed me something to hold the strip of brick sheet against while the hot glue cooled and keep the arch liners fairly straight.
I'll touch up any paint that has any hot glue around arch edges tomorrow.
