Your points are valid, Bill. I can't spend 6-8 solid hours in the shop like I used to, but I get in an hour here and an hour there, and sometimes 2-3 in a slow afternoon. It gets done, just takes a little longer. Having my shop in a walk-in attic space helps a lot. It's a 10 second walk from any living area to the building area. I didn't mean it to sound like I was jumping you.

PS For those of you who don't have unlimited building time, keep your shop organized and neat so you can grab any tool or part instantly without spending valuable time looking for it.
