Thanks Melgar!!!! I started building the first of the 4 sections... and, it started to rain!!! argh!!! I should be able to carry each section up the spiral staircase to the attic apartment.
I'm with you 100% GRJohn. I put tape on the floor yesterday and O72 made passage through the apartment a little tight (see photo). My wife was much happier with O63 (she probably wishes I had stuck with Super-O). I'm a whisker under 6' tall... the ceiling travels down to 42" where it meets the wall.
Everything under the sheets are trains... that pile is approximately half of my collection. I don't even really know if I'm a collector... an operator, for sure.
Update: Just finished the jig for the bends @ the front of the bench work (frame) and put the plywood strips in the swimming pool. I'll pull them out in the morning... and, put them in the jig for 24 hrs.
