Brian, working at home is a two edged sword as you discribed. But think of it this way, you can work on the trusses while the wood glue dries, then work on the plane while they are checking your drawings. I have always found that work will always be waiting for you. Sometimes play won't stick around and wait for the work to get finished. Plus you have a two hour time difference - work to boss. Get up and work while the factory is open and play when the shop closes. Lots of daylight left at 2:00 pm even in the winter. You forgot to mention if you have a family or not, they demand a lot of time and some of them don't like airplane smells. If you are a single guy and cant find time to build, well you either work too hard or play too hard.
Wink,Wink, Nudge, Nudge. Know what I mean? Know what I mean?

later, Roger.
