That said, larger blocks of time are certainly best for larger sections of the project. The main thing is to not just go down to the layout and stare/mull/(over)think about it too much. I know as well as anyone the value/necessity of "thinking my way into" a project, but lots of time can be wasted just staring at things. One strategy that's been working for me lately is to make out a list of those "bite-sized chunks" you can do when you have those little blocks of time. That way, you can get right to it, rather than just trodding the same mental ground all the time. And you can take advantage of opportunities for extra time and help as the come.
Case in point: All too often I schedule a "work" session and end up spending most of the time talking over different solutions rather than making any actual progress. True, progress does not always equal accomplishment, but sometimes it's better to make use of the extra hands at least as much as the extra brain.
Recent activity on the layout illustrates how having help and having bite-sized lists work together...
|Here's the other side of that hole through the wall - plywood to support the start of staging, all attached now.|
|A longer view, looking "west" back toward the Saybrook scene (though the hole in the wall). The subroadbed coming towards you will support the mainline going around the return loop.|
|Looking "east" again - and you can see where the subroadbed is going to join the return loop. The staging yard will evenutally occupy much of that vacant space just beyond the main section of plywood.|
