Thank you, both RRB and bondoman. Coming from such accomplished builders makes your comments even more welcome.
RRB--until last year I did nothing but aircraft, too. When I got into ships, I picked some simple ones--to start with, old Fujimi ships dating back to the '70's. I went with 1/700 scale because of cost and size.
Then, I studied up on the "Ships" forum here and at modelwarships, and picked up a lot of good insights.
I even checked bondoman's USS San Francisco over at modelwarships, in researching New Orleans. That's a neat, appealing ship. http://www.shipmodels.info/mws_forum/viewtopic.php?f=48&t=6603&start=200
Some things are very different with ship building. Not as much filling and sanding, although there is some of that. Mostly, though, it's assembly little modules of parts and gluing them on.
And using white/craft/Elmer's glue to bring the modules together. If you have an interest in some ships, or get tired of planes, naval modeling is a good addition. I don't intend to give up planes, just build both now.
On another subject, RRB--how did you get your group build badges to "play" consecutively, one after the other? It seems that I've run out of room in my signiture, and can't post more than 4 badges. So I dropped everything for now, except the current one. I tried to make a movie (Windows movie maker), put it on photobucket, then paste it into the signiture. It didn't work; just sat there.
