Hi Dan, I most of those pictures also, and I love it when I find a good crisp large format film photo that's been digitized (some from the library of congress are over 100mb!). I'm definitely trying to get things right but (confession time) I'm totally new to fusion 360 so limited skill set - and most of the "plans" out there on the internet for the USS Main, while good when compared to photos are also clear that they are "general arrangements" and deviate from the "as built".
I do plan to go back in the future and turn some iterations to get as accurate as possible -
As for the Torpedo Boat being on the USS Maine (or not), is actually an interesting topic to me - I have not yet found any photos with the torpedo boat mounted. I've seen websites that mention the Main was not equipped, the second boat was not completed, the first just became a training boat and "most likely ended as scrap". I've not seen any primary source of merit mention the fate of the torpedo boats.....except one. I actually posted that a few days ago up in the thread but the end got cut off so attaching the relevant portion to this post. The Scientific American journal says it was destroyed along with the Maine! (key ominous music)
(please don your aluminum foil hats!) Perhaps the little torpedo boat that was built was loaded up on the Maine just prior to the departure to Cuba.... and just maybe it was launched far off from the harbor as an insurance policy - if the Maine came under attack at night the torpedo boat would make for the harbor to try and attack the aggressor (large cruisers and battleships were easy prey for such a torpedo boat - especially in a harbor at night before "torpedo nets" were adopted). Possible that a small torpedo boat which can turn off it's boilers and run slow and silent into the port under remainder steam and pressure and either a) execute a hidden agenda to to torpedo a Spanish ship but mistake the Maine for it's target, or b.) slipped into the port in darkness with plans to be hoisted back on board when a lever, thought to be the one to discharge the air that would launch the torpedo , was in the utterly necessary and lightless stealth of darkness mistakenly the lever that actually launched the torpedo.
ha! gets you thinking!
Actually the whole reason I'm building these two torp boats is because, at 1/72 scale, they are just big enough for light weight RC gear and propulsion and I hope to be able to launch and recover them!
